TRT and Erectile Dysfunction: When Testosterone Helps — and When It Doesn't

TRT and erectile dysfunction are linked, but testosterone does not reliably fix erections. It may improve desire and modestly help erections in some men with symptoms and repeatedly low testosterone. Normal testosterone, other ED causes, and near-term fertility plans change the next step. Persistent ED needs its own assessment, even while you're on TRT.

The more useful answer depends on which of six situations you're in, and one of them includes an early heart warning. We'll get you to yours fast.

Educational information, not medical advice. This page can't diagnose low testosterone or ED. It is for adult men asking about testosterone deficiency and erection problems, not performance enhancement or other uses of hormones. An erection lasting more than 4 hours, or chest pain during sex, needs emergency care right away. (NIDDK; Cialis prescribing information)

What does the research show about TRT and erectile dysfunction?

TRT has a small average effect on erections in several studies, but the results differ by study and population. Improvements of roughly 2 to 3 points on one common erection scale may matter for mild ED but fall below thresholds used for moderate or severe ED. Desire improves more consistently than erections in the trials discussed here. (Study interpretation; Hudson review; TRAVERSE)

Here's the idea that makes the rest of this page click. Think of your sex life as having two dials.

  • The desire dial is how much you want sex. Testosterone has a real hand on this dial.
  • The erection dial is whether you can get and keep an erection firm enough for sex. This dial runs mostly on blood flow: healthy blood vessels, working nerves, and the right signals at the right moment.

Testosterone touches the second dial too, just not much in the average trial result. Blood-vessel disease, nerve problems, medicines, and mental health can all contribute to ED. A hormone result does not check all of those causes. (NIDDK)

So when a man starts TRT and says "I'm interested again, but things still don't work," he isn't imagining it. That pattern is consistent with the TRAVERSE findings. (Pencina et al., 2024)

What the studies actually found

We pulled the eight most important studies and guidelines into one table. That way you don't have to open eight tabs. Most numerical erection results below use the IIEF erectile function domain, a six-question survey scored up to 30. TRAVERSE used the shorter IIEF-5, scored up to 25. Those scales are not interchangeable; neither are before-and-after changes and differences between randomized groups.

TRT and erectile dysfunction table 2: What the studies actually found
Study or guideline Who was studied Erections Sex drive and activity What it means for you
TRAVERSE sexual-function study (Pencina et al., JCEM, 2024) 1,161 men aged 45–80 with low testosterone on two tests, low sex drive, and heart disease or high heart risk. Testosterone gel vs. placebo for up to 2 years. No statistically significant benefit over placebo on the IIEF-5 Desire and sexual activity improved, with benefits maintained at 24 months More wanting did not mean better erections in this population.
Testosterone Trials (Snyder et al., NEJM, 2016; Cunningham et al., JCEM, 2016) Men 65+ with average testosterone under 275 ng/dL; the sexual-function study included 470 men with low sex drive. Gel vs. placebo for 1 year. +2.6 points over placebo Desire and activity improved A small average erection gain in selected older men, not a promise for everyone with ED.
T4DM sexual-function analysis (Wittert et al., JCEM, 2025) 932 men aged 50–74 at high risk of, or newly diagnosed with, type 2 diabetes. Testosterone injections vs. placebo, both with a lifestyle program, for 2 years. Pathological hypogonadism—testosterone deficiency due to disease—was excluded. +2.5 points over placebo Desire improved A modest average effect in a different population—not a trial limited to men with established testosterone deficiency.
Spitzer et al. (Annals of Internal Medicine, 2012) 140 men aged 40–70 with ED and low or low-normal testosterone. Sildenafil dose fine-tuned first, then testosterone gel or placebo added for 14 weeks. Sildenafil phase: +7.7 points from baseline. Adding testosterone: no statistically significant extra gain. — The initial sildenafil phase was not randomized against placebo. The randomized comparison tested the testosterone add-on.
Cochrane review (Lee et al., 2024) 43 trials and 11,419 men overall; the key short-term sensitivity analysis covered 6 trials and 2,016 men. The review excluded classical primary or secondary hypogonadism—deficiency caused by disease of the testicles or hormone-control system. +2.4 points over placebo; moderate-certainty evidence — The authors judged this little to no clinically important difference using a 5-point threshold for this comparison.
Corona et al. meta-analysis (European Urology, 2017) 14 trials, 2,298 men +2.3 points overall; about +3.0 in studies of men starting below about 230 ng/dL — A subgroup finding, not a diagnostic cutoff or a personal benefit forecast.
Hudson et al. individual-patient analysis (Lancet Healthy Longevity, 2023) 17 trials supplied individual data on 3,431 men; the erectile-function analysis included 1,436 men. +2.1 points over placebo — The mean gain met the threshold used for mild ED. It did not establish that men with mild ED respond more than other men.
Endocrine Society guideline (Bhasin et al., JCEM, 2018) Systematic review behind the guideline A small, statistically significant improvement Small improvements in libido and sexual activity Statistical significance does not guarantee a noticeable benefit for an individual.

These reviews include overlapping trials. Their participant counts cannot be added to create a new evidence total, and differences between their average results do not rank treatment formats.

What "2 to 3 points" means in real life

The smallest meaningful change is not the same for every starting point. Rosen and colleagues estimated 4 points overall, but 2 points for mild ED, 5 for moderate ED, and 7 for severe ED. Those estimates came from tadalafil trials; they are useful guides, not a rule that every man notices exactly the same change. A 2-to-3-point average gain can meet the mild-ED threshold while falling below the others. (Rosen et al., 2011)

Now look at the Spitzer trial again. Same men, same scoring system. Sildenafil alone moved erection scores by about 7.7 points during the initial treatment phase. In the later randomized phase, testosterone added on top did not improve them significantly more than placebo. This was not a head-to-head trial of testosterone alone versus sildenafil. (Spitzer et al., 2012)

That's not a knock on testosterone. It's a different tool. Testosterone may help the desire dial when deficiency is part of the problem. Sildenafil and tadalafil act on the blood-flow part of the erection dial, with sexual stimulation still needed. (TRAVERSE; Viagra label; Cialis label)

Who is most likely to notice a difference?

The studies point in a few directions:

  • Men whose testosterone is clearly low. Corona's analysis found a bigger effect when starting levels were under about 230 ng/dL.
  • Men with mild ED. Hudson's average effect met the threshold for mild ED; this is not proof that mild ED predicts a larger response.
  • Men in the T4DM study. The findings about age, waist size, and depression differed by sexual outcome. They do not establish that older men or men with larger waists get a bigger erection benefit. Changes in waist size and depression were associated with changes in sexual function, not proof that those changes caused the improvement. (T4DM analysis)

The studies don't fully agree. Hudson didn't find that baseline testosterone predicted the treatment effect within the studied range; Corona found a larger effect in a lower-testosterone subgroup. Our read: if your testosterone is confirmed low, desire is the clearer possibility to discuss. Treat an erection gain as a possible bonus, not the whole plan. (Corona; Hudson)

What did TRAVERSE find about erections?

The TRAVERSE sexual-function substudy tested testosterone gel against placebo in 1,161 men with low testosterone and low sex drive, for up to two years. Sexual activity and desire improved; erection scores did not improve more than placebo. That separates a possible desire benefit from a dependable ED treatment. (Pencina et al., 2024)

Here's the result worth sitting with: TRAVERSE measured erections and found no statistically significant edge over placebo. That negative finding matters just as much as the improvement in desire. (Pencina et al., 2024)

Before you write TRT off, look at what did change. Men on testosterone reported more desire and sexual activity, and that held up for two years. For a lot of men, a missing sex drive is half the problem. Improving that part matters, even when erection problems need a separate treatment.

A few things about who TRAVERSE studied, so you can judge how well it fits you:

  • The men averaged about 64 years old and all had heart disease or high heart risk.
  • They used testosterone gel, not injections.
  • Their erection scores at the start sat in the moderate-ED range.

Younger, healthier men on a different treatment format could respond differently. These results do not prove that injections work better than gel for erections.

A rule worth knowing before you start

The American College of Physicians gives a clear, practical rule for men with age-related low testosterone (Qaseem et al., 2020):

  1. For age-related low testosterone, ACP suggests discussing treatment when sexual symptoms are the reason for considering it—not for energy, cognition, or physical function.
  2. Re-check within 12 months. ACP recommends that clinicians discontinue treatment for age-related low testosterone when sexual function does not improve. This is a clinician-led review, not a blanket instruction to stop TRT prescribed for other forms of hypogonadism.
  3. ACP favored injections over gels on cost grounds for that population. Its 2016 Medicare drug-cost figures were about $156 a year for injections versus about $2,135 for skin products. Those are historical medication figures, not current prices or complete care costs.

That review checkpoint helps you avoid continuing treatment without a clear benefit. Write it down.

Is any testosterone product FDA-approved to treat ED?

No testosterone product is approved specifically to treat erectile dysfunction. FDA-approved testosterone products treat specified forms of testosterone deficiency, called hypogonadism; approval is not permission to use testosterone for any sexual symptom or one low test. (FDA)

In April 2026, the FDA invited makers of approved testosterone products to explore a possible new indication: low libido in men with low testosterone that has no known cause. That announcement was an invitation to seek approval, not an approval, and it was about desire—not ED. (FDA, April 16, 2026)

Which care route fits you?

The right TRT provider is not the same for every person — it depends on whether low testosterone has been properly evaluated, your symptoms and health history, your fertility plans, your state, your insurance or cash-pay preference, your treatment-format preference, your budget, and whether online or in-person care is the better starting point. Some situations belong with primary care, urology, endocrinology, reproductive urology, or urgent or emergency care when the symptoms warrant it. Because a general answer cannot resolve those for you, use TRT Provider Guide's Find My TRT Path tool to map your situation to the right care route and the questions to ask before you pay.

Not sure where to start? Use the tool to compare care routes and prepare questions before you pay anyone. A clinician—not the tool—works out what is causing the ED. Map my TRT care route → Free and educational. It doesn't diagnose anything or decide if you'll get a prescription.

Can low testosterone cause erectile dysfunction?

Low testosterone can contribute to erectile dysfunction, but it is only one possible cause. Blood-flow problems, nerve conditions, medicines, and mental health can also affect erections. Low testosterone may affect desire as well, so the evaluation needs to separate wanting sex from getting and keeping an erection. (NIDDK; Endocrine Society)

You're far from alone. In the Massachusetts Male Aging Study, about 52% of men aged 40 to 70 reported some degree of ED. It rose from about 39% at 40 to 67% at 70 (Feldman et al., summarized by Boston University).

Low testosterone shows up in some men with ED. In one study of 157 men at an ED clinic, 36% had a testosterone reading under 300 ng/dL. That was a single clinic and a single measurement, not an estimate of confirmed testosterone deficiency in all men with ED. Roughly two of every three readings were not below that study's threshold; that does not establish those men's diagnoses. (Makhlouf et al., 2008)

What else causes ED?

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) lists diabetes among the most common conditions behind ED (NIDDK). Other common contributors:

  • Heart and blood vessel disease, high blood pressure, high cholesterol
  • Some medicines, including certain blood pressure drugs and antidepressants
  • Obesity, smoking, and heavy drinking
  • Nerve damage, including after prostate or pelvic surgery
  • Stress, anxiety, depression, and relationship strain
  • Poor sleep, including untreated sleep apnea

More than one contributor can be present at once. That's why a hormone test alone can't explain ED. (NIDDK)

What if my testosterone is normal and I still have ED?

Then a clinician needs to look beyond testosterone rather than prescribe TRT for the symptom alone. A normal result doesn't mean the problem is in your head, either. Blood flow, medicines, stress, and other factors still need assessment. An ED medicine may fit after that safety check. (Endocrine Society; NIDDK)

Can too-high testosterone cause ED?

The evidence doesn't give a clean answer. What's clear is that testosterone isn't a "more is better" hormone: these studies do not support raising it above the prescribed plan to improve erections. If you're on TRT and having trouble, see Why do I still have ED on TRT? below. (Endocrine Society monitoring guidance)

Claim check: A promise of ED relief is not proof that testosterone will fix erections. See the named examples and their limits in What TRT and ED programs claim—and what holds up.

How do you know if low testosterone is part of your ED?

You need an assessment and appropriate blood tests, not a guess from symptoms. Testosterone deficiency requires compatible symptoms or signs plus consistently low results, confirmed with repeat morning testing. The Endocrine Society recommends fasting morning measurements on separate days. (Guideline; July 2026 statement)

ED and low sex drive are reasons to discuss testosterone testing. The AUA recommends morning total testosterone measurement in men with ED; the Endocrine Society also lists ED among the symptoms that can prompt evaluation. Neither treats the symptom as a diagnosis. (AUA ED guideline, Statement 4; Endocrine Society, Table 3)

What a real diagnosis takes

  1. Symptoms or signs that fit low testosterone, like low sex drive, ED, fewer morning erections, or low energy. Symptoms alone don't count as a diagnosis, the Endocrine Society stressed in July 2026 (statement).
  2. Repeat early-morning testing on a separate day to confirm a low result. The Endocrine Society recommends fasting for these measurements because food can lower the result. The AUA calls for two separate early-morning total testosterone measurements; the fasting recommendation here comes from the Endocrine Society. (Endocrine Society, diagnostic technical remarks; AUA testosterone guideline, Statement 2)
  3. Consistently low results interpreted in context. The AUA uses under 300 ng/dL as a reasonable cutoff supporting diagnosis. The Endocrine Society describes 264 ng/dL as a lower reference limit from healthy, nonobese men aged 19–39 using standardized assays. Neither number diagnoses every patient by itself; the test method, reference range, symptoms, and sometimes free testosterone matter. (AUA testosterone guideline; Endocrine Society)
  4. A good lab. The Endocrine Society recommends accurate, reliable testing, ideally from a method certified through a standardization program such as CDC HoST. Results and reference ranges can differ between methods. (Endocrine Society)

A few terms you'll see on your results:

  • Total testosterone: all the testosterone in your blood.
  • Free testosterone: the small part not attached to proteins. It may be assessed when total testosterone is borderline or a condition changes SHBG.
  • SHBG (sex hormone-binding globulin): a protein that grabs testosterone. High or low SHBG can make total testosterone look misleading.
  • LH (luteinizing hormone): a signal from the pituitary gland to your testicles to make testosterone. It helps show why testosterone is low.

One low number isn't a diagnosis

No single result, cutoff, or quiz can diagnose low testosterone. If someone offers you testosterone after one afternoon test, ask why they aren't confirming it.

You may have to ask for the test

An online ED visit does not automatically include a full testosterone evaluation. Hone's ED page does describe hormone testing, so it would be wrong to say online ED programs never test testosterone. Ask what your own visit includes, whether a low result will be confirmed, and who will evaluate the other possible causes. (Hone's published process; diagnostic standard)

Do morning erections prove my testosterone is normal?

No. Morning erections are useful information, but they don't replace a clinical assessment and appropriate blood tests. Bring what you've noticed to your appointment. (NIDDK)

Which of these 6 situations are you in?

What TRT can do for your erections depends on your situation. Find the row that sounds like you, then use the first step, the right clinician, and the exact question to ask. More than one row can apply.

We built this map from the trials, guidelines, drug labels, and FDA sources on this page. It isn't a diagnosis. It's a way to walk into your next appointment knowing what to ask.

TRT and erectile dysfunction table 3: Which of these 6 situations are you in?
Your situation What the evidence says about TRT and your erections Your first step Who to see The question to ask
1. I have ED and my testosterone has never been properly tested. Not established by symptoms alone. Testosterone testing is one part of the evaluation. Arrange an ED assessment, including whether morning testosterone testing and a repeat low result are needed, plus a review of heart and diabetes risk. Primary care or urology; online care needs a plan for any examination or local testing. "Besides testosterone, what should we check to find the cause?"
2. I have ED and my low testosterone is confirmed. A possible modest erection benefit and a clearer desire benefit; neither is guaranteed. Discuss whether there are separate reasons to treat testosterone deficiency and ED. Settle fertility plans first. Primary care, urology, or endocrinology; an online clinician only when the needed assessment and follow-up are available. "Should we treat both, and how and when will we judge whether each treatment is working?"
3. I have ED but my testosterone is normal. A normal result does not establish a reason for TRT. Review blood flow, medicines, sleep, and stress; discuss an ED treatment after the safety assessment. Primary care or urology. "What's most likely causing this, and which ED treatment fits my health?"
4. I'm on TRT. My sex drive is better, but erections aren't, or they got worse. Possible even when testosterone rises: desire and erections are different outcomes. Timing alone doesn't prove TRT caused it. Don't stop or change your dose on your own. Ask your prescriber for a review (see the checklist below). Your current prescriber; urology if it isn't resolved. "What should we review before assuming I need a different dose?"
5. My ED medicine isn't working well enough. Testosterone isn't an automatic add-on fix; in the Spitzer trial it added no significant benefit to optimized sildenafil. Review how the medicine was taken, the dose, and other causes. The prescriber or a urologist. Don't combine ED drugs on your own. "Have we given this medicine a fair trial, and what else fits my health?"
6. We're trying to have a baby now or soon. Testosterone therapy can lower sperm production. Guidelines say not to prescribe it to men trying to conceive. Get a fertility-aware opinion before a treatment decision; discuss any current TRT with its prescriber. Urology or reproductive urology. "What options fit my symptoms and our plans for a baby, and what are their limits?"
🚩 Red flags, any situation — An erection lasting over 4 hours, or chest pain or trouble breathing during sex: emergency care now. ED that appears with diabetes or high blood pressure that's never been checked: see a doctor soon. ER, primary care, or cardiology —

Why do I still have ED on TRT?

ED can continue or begin while you are on TRT, and a higher testosterone result does not explain every erection problem. Your prescriber should review the treatment response, other possible causes, and routine safety checks. Do not change hormones or add medicines on the strength of a symptom or forum suggestion. (NIDDK; Endocrine Society)

If you thought fixing your testosterone would fix everything, you're in good company. A forum thread titled “ED On TRT. Bloods good on paper” captures that frustration. It is one person's account, not a verified interpretation of laboratory results or evidence that a treatment works.

Your labs can look great and your erections can still struggle. Both things can be true, because they run on different dials.

Seven things to ask your prescriber to review

Bring this list. You aren't diagnosing yourself. You're making sure nothing gets skipped.

  1. Blood pressure. In 2025 the FDA required class-wide labeling changes about increased blood pressure with testosterone products. High blood pressure can also contribute to ED. These are reasons to review it, not proof that it caused your symptoms. (FDA, February 28, 2025; NIDDK)
  2. Hematocrit. This is the share of your blood made up of red blood cells, and testosterone can raise it. Guidelines call for checking it before treatment, at 3–6 months, and then annually. This is a safety check, not a stand-alone explanation of ED. (Endocrine Society, monitoring table)
  3. Whether other hormone tests are indicated. Estradiol is an estrogen hormone, but ED alone does not prove it is too high or too low. Ask which tests your symptoms and history justify; do not assume you need an estrogen-blocking drug. (Endocrine Society, diagnostic assessment)
  4. Where you are in your dosing cycle. Ask if your symptoms track with the timing of your treatment, such as near the end of a dosing interval.
  5. Other medicines. Some blood pressure drugs and antidepressants are known ED contributors (NIDDK).
  6. Blood flow, blood sugar, and sleep. Diabetes and blood-vessel disease can affect erections. Sleep problems also belong in the medical history, and untreated severe sleep apnea is a concern before TRT. Testosterone is not a substitute for evaluating these conditions. (NIDDK; Endocrine Society)
  7. Pressure and stress. Some men feel they have "no excuse" anymore once their testosterone is treated. Anxiety and stress can contribute to ED. A counselor or sex therapist may help with those contributors. (NIDDK)

Can TRT make ED worse?

New or worse erection problems on TRT deserve a real review, not a shrug. Something in the list above may have changed, or the original ED cause may never have been hormonal. When ED appears after starting TRT, that doesn't prove TRT caused it, and it doesn't prove TRT didn't. A clinician needs the timing, product, symptoms, and other medicines to assess what happened. (NIDDK; Endocrine Society monitoring)

How long should I wait for TRT to help?

There's no guaranteed date. In TRAVERSE, sexual activity had improved by the 6-month assessment, with benefits maintained at 24 months, but erections did not improve more than placebo. The Endocrine Society recommends assessing response and adverse effects at 3–12 months after starting treatment; some safety tests come earlier. ACP's review within 12 months applies to testosterone used for age-related low testosterone and sexual symptoms. (TRAVERSE; Endocrine Society; ACP)

The AUA also advises clinicians to discuss stopping treatment at 3–6 months when testosterone levels have returned to normal but symptoms have not improved. That is a prescriber-led decision, not an instruction to stop on your own. (AUA's guideline announcement)

Those are check-in points. They aren't a reason to sit through worsening symptoms. Ask your prescriber to set a clear review date for your symptoms.

What happens to erections if I stop TRT?

Testosterone from outside your body can suppress your own hormone production. After stopping, low-testosterone symptoms may return; the course depends on the original condition and the treatment history. Plan any change with your prescriber rather than assuming that stopping will either fix ED or make it permanent. (Endocrine Society)

Can you take Cialis or Viagra with TRT?

Testosterone and an ED medicine can be prescribed together when a clinician finds a reason for each and checks that the combination fits your health. Combining them does not guarantee better erections. Sildenafil and tadalafil must not be used with nitrates, recreational nitrites such as poppers, or riociguat because blood pressure can fall dangerously. (Spitzer trial; Viagra label; Cialis label)

Sources: FDA testosterone information · FDA compounding information · Viagra label · Cialis label · Schedule III regulation · Endocrine Society

"Schedule III" means testosterone is a federally controlled drug. It needs a valid prescription, and it comes with extra legal rules (21 CFR 1308.13).

Does adding testosterone make ED pills work better?

The experts don't fully agree, so here's the honest version:

  • The AUA says maybe. Men with ED and low testosterone should be told an ED pill "may be more effective if combined with testosterone therapy" (AUA ED guideline, Statement 12).
  • The trial that tested exactly that said no significant boost. In Spitzer 2012, adding testosterone to a fine-tuned sildenafil dose didn't significantly improve erections over placebo.
  • The Cochrane review rates the combination evidence as low certainty. Its pooled short-term estimate did not establish a reliable, clinically important add-on benefit. (Full review, comparison 4)

Our read: if symptomatic testosterone deficiency is confirmed, treating it may make sense for that diagnosis and related sexual symptoms. Just don't assume it will rescue an ED pill that isn't working.

Daily Cialis or as-needed?

Both are FDA-approved for ED. Daily tadalafil comes in low doses (2.5 to 5 mg), and the 5 mg daily dose is also approved for urinary symptoms from an enlarged prostate (Cialis label). That can matter for men over 50 with both problems. Which one fits you is a choice to make with your prescriber.

⚠️ ED medicine safety: read this before any pill

  • Never take sildenafil, tadalafil, vardenafil, or avanafil with nitrates (like nitroglycerin, isosorbide) or poppers (amyl nitrite). Blood pressure can crash.
  • Never take them with riociguat (Adempas).
  • If you ever have chest pain after taking an ED pill, seek emergency care and tell the team what you took and when. The tadalafil label permits consideration of nitrates after at least 48 hours, and the avanafil label after at least 12 hours, only when medically necessary in a life-threatening situation, under close medical supervision and blood-pressure monitoring. These are not safe self-use timers. For sildenafil, its label says a safe nitrate interval is not known.
  • An erection lasting more than 4 hours is an emergency.
  • Sudden vision loss or sudden hearing loss means stop the medicine and get help right away.

Sources: Viagra label · Cialis label · Stendra label

What we found on public pages: Henry Meds, Maximus, and Hims publish nitrate warnings in the treatment or safety pages cited here. The Male Excel and Hone ED landing pages we reviewed did not display that warning in their main page text. This checks those pages—not their private intake, linked consent documents, or clinical screening. A missing landing-page warning does not establish that a clinician omits the check. (Henry Meds; Maximus; Hims; Male Excel; Hone)

Compounded ED products are not the same as generic Viagra or Cialis

Online programs sell chews, mints, troches, combination pills, and liquids. Some are compounded, meaning they are prepared by a pharmacy or outsourcing facility rather than supplied as an FDA-approved finished product. Compounded drugs are not FDA-approved. FDA does not review them for safety, effectiveness, or quality before marketing. (FDA)

FDA-approved generic sildenafil and tadalafil tablets are available. Ask for the exact manufacturer and finished product—not just the ingredient name or the word "generic"—when approved medicine is your priority. Approval of an ingredient in one product does not approve a compounded chew or multi-drug blend. (FDA; Viagra label; Cialis label)

What if ED pills don't work for me?

You still have options. NIDDK lists treating the underlying cause, counseling, vacuum devices, prescribed medicines placed in or injected into the penis, and surgery such as a penile implant (NIDDK). These belong with a urologist. Testosterone isn't a substitute for them.

Is erectile dysfunction a warning sign for heart disease?

It can be. ED can be a marker of underlying blood-vessel disease and may appear before heart symptoms, but it does not diagnose heart disease or predict a personal countdown. A cardiovascular risk assessment matters alongside treatment of the erection problem. (Princeton IV consensus)

This is the part that could matter beyond your sex life.

  • In a study including 8,063 men without cardiovascular disease at entry, new ED was associated with a 25% higher adjusted hazard of a later cardiovascular event—not proof that ED caused the event (Thompson et al., JAMA, 2005).
  • The Princeton III panel described a 2-to-5-year interval before coronary symptoms in some studies of men with ED. The newer Princeton IV consensus also treats ED as a cardiovascular risk marker. Neither makes that interval a forecast for you. (Princeton III; Princeton IV)
  • The AUA tells clinicians to inform men with ED that it's a risk marker for heart disease (AUA ED guideline, Statement 3).

If ED is new for you, ask your doctor to check your blood pressure, blood sugar, and cholesterol. A pill can treat the symptom. A check-up can catch what's behind it.

Chest pain, pressure, or shortness of breath during sex needs emergency care.

Will TRT affect fertility (and does that change the ED plan)?

Yes—testosterone therapy can suppress sperm production, and major guidelines advise against it when near-term fertility is a goal. ED medicines are a separate treatment decision, not a fertility treatment. If a baby is in your plans soon, see a urologist or fertility-aware clinician before starting TRT. (Endocrine Society)

Testosterone from outside your body can suppress LH and FSH, the pituitary signals involved in testosterone and sperm production. For a man with ED who also wants children, that changes the treatment discussion.

  • The AUA says to discuss sperm effects with men who may want children, and not to prescribe testosterone to men currently trying to conceive. (AUA testosterone guideline, Statements 16 and 23)
  • The Endocrine Society also recommends against testosterone for men planning fertility in the near term.
  • Medicines such as clomiphene, enclomiphene, and hCG are not TRT. They work differently and are not interchangeable with testosterone. Clomiphene is approved for ovulation problems in women; prescribing it for men is off-label. Enclomiphene is not an FDA-approved drug. Pregnyl, an hCG product, has an approved indication for selected cases of male hypogonadotropic hypogonadism—a deficiency involving hormone signals from the brain. These facts do not establish which option fits your fertility problem. (Clomid label; OPSS, January 2026; Pregnyl label)

Nobody can promise that fertility will be protected or will come back on a set timeline. Bring that concern to a urologist or reproductive urologist before choosing treatment. (Endocrine Society)

What other health issues can change the plan?

Fertility is not the only reason to choose a more specialized assessment. The Endocrine Society advises against starting testosterone in men with certain conditions, including elevated hematocrit, untreated severe sleep apnea, breast or prostate cancer, uncontrolled heart failure, or a heart attack or stroke within the previous six months. Prostate findings and clotting disorders can also require further evaluation. This is not a self-clearance checklist; disclose your history to the clinician before paying for treatment. (Guideline)

Can you get TRT and ED treatment from the same online program?

Yes. Several online programs offer testosterone care and ED medicines, but one brand does not guarantee one prescriber, one bill, or the same state coverage. Confirm the exact treatment, repeat-testing plan, and combined cost before paying; the snapshots below describe published offers, not a ranking of clinical care. (Male Excel FAQ; Hone membership details)

This section is for men in situation 2: confirmed low testosterone plus ED. If your testosterone is normal, untested, or you're trying to conceive, go back to the six situations. Choosing a hormone subscription is not the first decision to make.

How the programs handle TRT and ED

Provider-stated offers, checked October 5, 2026. A published listing confirms what a company says it offers—not what a clinician will prescribe to you or which pharmacy will dispense it.

TRT and erectile dysfunction table 5: How the programs handle TRT and ED
Program Actual testosterone treatment ED medicines and published pricing Can both be discussed in one program? Testing and state limits
Male Excel Testosterone cypionate injections and compounded testosterone cream. Its separately marketed Triclozene contains clomiphene, thyroid medicine, and selenomethionine; it is not testosterone or TRT. Sildenafil 100 mg or tadalafil 20 mg: $35 first month, then $65/month. Tadalafil 5 mg: $29 first month, then $89/month. The page calls these generic Viagra/Cialis. These are product listings, not dose advice. Its FAQ says to discuss ED medicines during the TRT consultation. The price of adding ED care to an existing plan still needs confirmation. The $99 consultation offer includes an initial home kit. Hormone and ED state lists differ; see the 37-state overlap below.
Hone Health Injectable testosterone; compounded testosterone cream and troches. Tadalafil from $25/month plus a qualifying membership. The ED landing page and newer membership guide show different sildenafil and PT-141 prices, so obtain a current quote. Plus and Premium list both hormone and ED treatment options. Basic excludes hormone therapy. Same membership does not prove every visit uses the same clinician. Plus: initial test $45; confirmation $45 at a lab or $80 at home. Premium: initial test $65; confirmation $25. Its published state list differs by membership.
Henry Meds Compounded TRT from $129/month; FDA-approved Kyzatrex oral testosterone from $179/month, with the page excluding California for Kyzatrex. Sildenafil or tadalafil products, with approved and compounded options described. $50/month, billed $150 for a three-month supply. Separate TRT and ED programs are advertised; confirm whether visits and charges can be coordinated. TRT page describes lab review and an age range of 35–65. Confirm access for your state and exact product before payment; a complete common state list was not established here.
Maximus Compounded injection and cream offers from $99.99/month; oral testosterone from $149.99/month. Enclomiphene is a separate, non-TRT treatment. Compounded sildenafil, tadalafil, vardenafil, or combinations. Entry offer: $35.99 every 30 days for four 10 mg tablets; the pricing footnote does not identify which drug that entry dose represents. Separate treatment offers; a shared brand does not establish a single combined fee or consultation. At-home testing is advertised with testosterone care. Confirm repeat testing, your specific plan's state access, and product before paying.
Hims The testosterone page still marks injectable testosterone and Kyzatrex “Coming 2026.” That page does not confirm their availability now. Its marketed enclomiphene-plus-tadalafil product is not TRT. FDA-approved tablet options and compounded ED products are marketed separately. Prices vary by product, quantity, and billing plan; an ED price is not a combined testosterone-care quote. An enclomiphene/ED bundle is not proof of an available TRT/ED program. A lab-based assessment is described for its hormone-related offer, and the page says availability is not all 50 states. Check the exact medicine, not just the “testosterone” category name.

What we actually verified

  • Date and method: October 5, 2026; public provider treatment pages, membership explanations, FAQs, terms, and safety pages linked here.
  • Confirmed as published: the listed prices and billing units, product descriptions, Male Excel's differing state exclusions, Hone's published membership/state lists, and Hims' coming-soon labels. We recalculated the subtotals below.
  • Provider-stated, not independently tested: services included, clinician access, refill processes, laboratory panels, partner pharmacies, and product descriptions. A statement that a product is “generic” does not identify its manufacturer or confirm the particular dispensed drug.
  • Not established: your eligibility, final prescription, complete individual first-year quote, assigned prescriber or pharmacy, appointment wait time, every repeat-test charge, or the process and cost of obtaining your medical records. No private checkout, support conversation, licensing-database check, prescription, or treatment outcome was tested for this article.

Male Excel: check the two state lists and the medication bundle

Male Excel may be worth investigating after a clinician has established a reason for both testosterone care and ED treatment. Its home test lists testosterone, estradiol, thyroid markers, DHEA-S, and PSA, a prostate blood marker. A broader panel alone does not make it the best provider or replace repeat morning testosterone testing. Before ED medicines, its page requires a physical with vital signs taken by a provider within the past three years. (Testing and care FAQ; ED requirements; diagnostic standard)

One thing to know first. Male Excel's published injection package includes thyroid medicine, not just testosterone and injection supplies. Do not treat that bundle as proof you need thyroid treatment. Ask what each medicine is treating and whether a testosterone-only plan is available and priced differently. (Published package)

Its ED page lists sildenafil and tadalafil tablets; it does not list chews, mints, troches, liquids, or PT-141. That is a product-list observation, not proof that any alternative format is better or that the exact tablet dispensed has been independently checked. When FDA-approved medicine is your priority, ask for the finished product and manufacturer. (Male Excel ED; FDA)

Check your state first. Male Excel's two state lists don't match. From its published exclusions, we calculate that it offers both hormone and ED care in 37 of the 50 states; this calculation does not include Washington, DC. Men in North Dakota and South Carolina are excluded from its ED offer but not its hormone list. Men in Alabama, Arkansas, Connecticut, Hawaii, Idaho, Louisiana, New Hampshire, and Rhode Island are excluded from its hormone offer but not its ED list. Alaska, Minnesota, and Mississippi are excluded from both. Published coverage is not a prescription guarantee. (Hormone exclusions; ED exclusions)

What the published prices add up to:

TRT and erectile dysfunction table 6: Male Excel: check the two state lists and the medication bundle
Male Excel offer Reproducible calculation Advertised-rate subtotal—not a complete first-year quote
Injection package and membership $99 initial consultation/home kit + (12 × $99 membership) + (12 × $120 starting monthly-equivalent package price) $2,727
Above package plus as-needed ED offer $2,727 + $35 first month + (11 × $65) $3,477
Above package plus daily-tadalafil offer instead $2,727 + $29 first month + (11 × $89) $3,735

The medication package is billed in 60-day supplies and includes thyroid medicine. Twelve monthly equivalents represent six such supplies, or 360 days—not necessarily every charge before a 365-day anniversary. Shipping/handling, tax, any separate ED consultation, repeat testing beyond the stated offer, and the exact prescription may change the amount. Those unknown charges are not assumed to be zero. Ask for the number of shipments, refill dates, and total charges for your first 365 days. (Costs; ED prices; terms)

Follow-up and cancellation: Its FAQ describes refill assessments every two months and testing that may be needed at six and twelve months; that does not promise every required test is included. It lists AnazaoHealth and WellDyneRx-Fl as pharmacy partners, but this does not identify your dispensing pharmacy. The FAQ says there is no contract and describes a reminder 48 hours before refills are billed and shipped. Its terms say all sales and membership fees are nonrefundable. “Cancel anytime” is not a refund promise. FSA/HSA eligibility depends on the expense and your account rules; the company says it does not supply letters of medical necessity. (FAQ; terms)

Comparing Male Excel for both conditions? Start with the ED state restrictions and the written combined quote—not the introductory price. Review Male Excel's ED prices and state restrictions → Direct provider information link. A licensed clinician decides whether treatment is appropriate; this is not an eligibility check.

Hone Health: choose a hormone-eligible membership, not Basic

Hone lists hormone care and ED medicines within Plus and Premium, but its $25/month Basic membership excludes hormone therapy. A shared membership can make coordination easier to ask about; it does not establish that the same clinician will manage both prescriptions. Its September 2026 membership guides give a clearer cost breakdown than the older ED landing page. (Basic exclusions; Plus; Premium)

What to know:

  • Tadalafil starts at $25/month plus membership. Injectable testosterone starts at $28 per vial, not per month. The number of vials and their supply duration depend on the prescription. The cream and troche listings are explicitly compounded, at $60/month. (Premium medication list)
  • Plus is $135/month. Its starting test is $45, with a separate $45 confirmation test at a lab or $80 at home. Premium is $155/month, with a $65 starting test and $25 confirmation test. The guides describe follow-up labs, consultations, and shipping as included in membership, with medication charges separate. (Plus; Premium)
  • States are published. Hone's list names 35 states for men's Plus and 34 for men's Premium. Hawaii and South Dakota appear for Plus but not Premium; New York appears for Premium but not Plus. Use the exact membership list, not a general claim that Hone serves your state. (State availability, updated September 4, 2026)
  • Published prices differ between pages. The ED page lists sildenafil at $40/month and PT-141 at $130/month plus membership; the newer Premium guide lists sildenafil at $25/month and compounded PT-141 spray at $140/month. A quote needs the exact product and current plan. Hone identifies the spray as compounded, not FDA-approved. It is not interchangeable with FDA-approved sildenafil or tadalafil. (ED landing page; Premium guide)

PT-141 approval is product-specific. Vyleesi is an FDA-approved bremelanotide injection for a defined low-desire disorder in certain premenopausal women—not for ED in men. That approval does not cover a compounded PT-141 spray. (Vyleesi prescribing information; FDA compounding guidance)

TRT and erectile dysfunction table 7: Hone Health: choose a hormone-eligible membership, not Basic
Hone plan with tadalafil Twelve-month membership + starting and confirmation tests + tadalafil What is still missing
Plus, lab confirmation $45 + $45 + (12 × $135) + (12 × $25) = $2,010 All testosterone medication costs; final product, quantity, and any other charges
Plus, home confirmation $45 + $80 + (12 × $135) + (12 × $25) = $2,045 All testosterone medication costs; final product, quantity, and any other charges
Premium, lab confirmation $65 + $25 + (12 × $155) + (12 × $25) = $2,250 All testosterone medication costs; final product, quantity, and any other charges

These are partial care-cost calculations, not complete TRT-plus-ED totals. A $28-per-vial price cannot be converted into a yearly testosterone cost without the prescribed quantity and refill schedule. Basic is not a hormone-treatment option. (Basic; Plus; Premium)

Hone's membership guides say cancellation takes effect at the end of the billing period. That does not establish a refund for a medicine already prescribed, ordered, or shipped. Ask who handles both prescriptions, how to reach the clinician between visits, which pharmacy will dispense each product, and how to obtain your records before joining. (Plus terms; Premium terms)

Looking for one program to discuss both prescriptions? First check that the membership covers hormone care and serves your state. Review Hone's hormone-care membership and testing costs → Direct provider information link. The plan lists treatment options; it does not guarantee a prescription or a particular clinician.

Other programs we checked

  • Henry Meds lists visits, labs, medicine, and shipping in its TRT pricing: compounded TRT starts at $129/month, with the separate ED program at $50/month. 12 × ($129 + $50) = $2,148 at those starting rates; FDA-approved Kyzatrex is a different, higher-priced offer. Its pages include nitrate and heart-health warnings. Although cancellation is offered, a multi-month plan can leave a remaining balance due. Confirm the exact formulation and billing commitment, rather than treating the starting price as every patient's complete first-year cost. (TRT; ED and cancellation)
  • Maximus lists injection and cream offers from $99.99/month and ED treatment from $35.99 every 30 days. 12 × ($99.99 + $35.99) = $1,631.76 is a twelve-payment comparison, not a complete 365-day bill: a 30-day ED subscription has a thirteenth charge at day 360 if it starts at day zero and continues. The entry ED price covers four 10 mg tablets, not an unlimited supply; the exact drug needs confirmation. The testosterone and ED offers reviewed are compounded. Its ED subscription auto-renews and can be canceled through the account or support, subject to its refund policy. (Testosterone offers; ED pricing and billing)
  • Hims still labels both Kyzatrex and injectable testosterone “Coming 2026” on the page checked. Do not count a future product as an available TRT program. Its enclomiphene/tadalafil offer is a different, non-TRT treatment. (Hims testosterone page)

These are offer snapshots, not evidence that any program provides better erections, safer care, or a cheaper complete plan for you. The public information does not support a clinical winner based on a bigger lab panel, one membership, or a starting price alone.

The cheapest route may be your own doctor

If your testosterone is normal (situation 3), or you only need ED care, compare the total cost of a primary care visit and a local generic prescription before paying for a hormone membership. Do not add testosterone simply to access an ED medicine. Get the pharmacy price for the exact tablet, strength, quantity, and refill plan; an old coupon price is not a current quote.

Medicare Part D excludes drugs used for sexual or erectile dysfunction. The law allows an exception when the drug is used for another FDA-approved condition, so coverage can differ by diagnosis and plan. Ask your plan about the exact prescription and any prior authorization; a confirmed low-testosterone result alone does not guarantee coverage. (Social Security Act §1860D-2(e)(2)(A))

For the separate provider-selection question—including more programs, state access, and cancellation—see our comparison of online TRT providers for erectile dysfunction. Here, the main decision remains what needs evaluation and whether each treatment has a reason to be considered.

What must a complete first-year quote include?

Ask for all charges during the first 365 days, not just twelve times a teaser price. The quote should separate the first test, any required confirmation test, consultation, membership, each medicine and supply quantity, follow-up visits and labs, shipping, tax, and renewals. Ask whether any minimum term or cancellation deadline changes those charges.

For both prescriptions, also ask: “Who is my clinician, can they treat me in my state, do I need an in-person visit, which pharmacy dispenses each product, who handles refills, and how do I get my records?” A published price table cannot answer those personal details.

It can be, with a valid prescription from an appropriately licensed and DEA-registered clinician acting within the law. Testosterone is Schedule III. The current federal temporary rule extends qualifying telemedicine prescribing of controlled medicines without a prior in-person examination through December 31, 2026; for this testosterone pathway it requires real-time audio-video care and the rule's other conditions. State law, professional practice requirements, and a clinician's need for an examination still apply. A questionnaire alone does not satisfy that pathway or guarantee a prescription. (Schedule III regulation; DEA/HHS fourth temporary extension)

Which TRT and ED marketing claims hold up?

Some wording is more certain than the evidence, and some drug or care labels need more context. We checked seven examples below against public source pages, research, and official rules. These are editorial assessments of the wording—not ratings of a company or findings of a legal violation.

TRT and erectile dysfunction table 8: Which TRT and ED marketing claims hold up?
Published wording checked October 5, 2026 Where and context What the evidence supports Our assessment of the wording
“TRT typically relieves ED symptoms” Defy Medical TRT page, explanation of sexual symptoms Some trials show a modest erection benefit; TRAVERSE did not find improvement over placebo. Too broad as an expectation. Testosterone is not a dependable stand-alone fix for ED.
“Relief from erectile dysfunction (ED)” Defy Medical TRT page, under results that patients reportedly experienced A provider's report of patient experiences does not establish the usual result or prove treatment efficacy. Patient-report context matters. This is not a trial finding or a guaranteed outcome.
“FDA-approved medications” alongside a separately promoted “4-in-1” liquid ED offer Taurus Meds homepage; its ED page does disclose compounding The site's four-drug liquid is not made FDA-approved by approval of ingredients in other products. Read the product-specific disclaimer. The broad homepage wording must not be carried over to the compounded finished product.
“Testosterone Support” in an ED product name Hims product safety page; the ingredients listed are tadalafil, zinc, L-arginine, and B vitamins That ingredient list contains no testosterone or enclomiphene. The name does not establish treatment of testosterone deficiency. Not TRT. Do not choose it thinking it replaces testosterone.
“Helps restore drive and overall performance” Male Excel homepage A desire benefit can fit the evidence in appropriately selected men. “Performance” is not a defined erection outcome. Partly supported, partly vague. It does not establish a reliable erection benefit.
“your care is delivered entirely online” Male Excel TRT FAQ, answer about in-person care The same page's footer says DEA or state rules may require an in-person exam. Federal flexibility does not erase those limits. Read the FAQ with its footer qualification. It is not a guarantee that an in-person visit can never be needed.
“TRT may help improve symptoms when low testosterone is a contributing factor” Male Excel TRT FAQ, which also mentions other treatment depending on the cause This is a conditional claim, not a promise that TRT fixes every case of ED. Supported in that limited sense. Diagnosis, safety, and other ED causes still matter.

How to read any TRT or ED ad in 10 seconds:

  • Does it say "FDA-approved"? For which drug, exactly?
  • Does it promise better erections from testosterone alone?
  • Does it show the nitrate warning near the ED medicine?
  • Does it require two early-morning tests before testosterone?

How did we research and verify this page?

We checked the published trial reports, clinical guidance, medicine labels, and federal sources supporting this page, alongside the public program pages cited above, on October 5, 2026. We report what those sources establish and distinguish it from our interpretation. This is public-source editorial research, not a clinical review or a hands-on test of any program.

What we actually verified (medical and regulatory)

  • Checked: the populations, comparisons, reported outcomes, and interpretation limits in the eight-row evidence table; the diagnosis and monitoring recommendations described here; prescribing information for sildenafil, tadalafil, and avanafil; fertility-related drug indications; FDA compounding information; testosterone scheduling; the temporary federal telemedicine rule; and the cited Medicare exclusion. Source access varied: we used accessible full texts and primary abstracts, with the current Endocrine Society statement alongside its guideline. We do not claim to have re-read every inaccessible guideline page or every product label.
  • Our original work: the evidence table with its different scales and populations made explicit, the six-situation map, the ED-on-TRT review checklist, the full appointment worksheet, the provider-stated offer table, the state-overlap calculation, the reproducible cost subtotals, and the marketing-claim comparison.
  • Not established: your diagnosis, whether a treatment suits you, how you'll respond, or your insurance coverage.
  • Review status: By TRT Provider Guide. Not clinically reviewed.

Our full process is in How We Review TRT Providers. It separates verified facts, provider-stated facts, customer-experience signals, and our own editorial conclusions. See our editorial standards, privacy policy, and corrections policy for how the site handles sources, data, and updates.

Why no patient success stories? Testimonials can't tell you whether testosterone will help your erections, and we won't use them as if they could.

What else should you know about TRT and erectile dysfunction?

Testosterone tests, ED symptoms, treatment format, and insurance each answer a different question. These answers address the remaining practical details without turning a symptom or product listing into a treatment decision.

Does TRT cure erectile dysfunction?

TRT is not a guaranteed cure for ED. It may improve erections in some men with symptomatic testosterone deficiency, but its average erection effect is modest in several trials and was not significant in TRAVERSE. An ED assessment and an appropriate ED treatment may still be needed. (TRAVERSE; Cochrane; NIDDK)

Can TRT cause ED?

Erection problems can continue or appear while taking TRT. Timing does not establish the cause: the clinician needs to review other medicines, vascular and metabolic health, the treatment response, and safety checks. Ask for that review instead of changing the dose yourself. (NIDDK; Endocrine Society)

Will Viagra work if I have low testosterone?

It can. In a trial of 140 men with ED and low or low-normal testosterone, a fine-tuned sildenafil dose raised erection scores by about 7.7 points during the initial, nonrandomized phase. Adding testosterone in the later randomized phase did not significantly improve on placebo. (Spitzer et al.)

Can I take Cialis with testosterone injections?

They can be prescribed together when a clinician checks the indication for each and the safety of the whole medication list. Tadalafil must not be taken with nitrates, poppers, or guanylate cyclase stimulators such as riociguat. (Cialis label; Spitzer trial)

Is daily Cialis better than as-needed on TRT?

Neither is "better" for everyone. Both as-needed and daily tadalafil regimens are approved for ED; the daily 5 mg regimen is also approved for enlarged prostate symptoms. That describes approved uses, not a dose recommendation for you. (Cialis label)

What testosterone level causes ED?

There's no single level that causes ED in every man. A low reading does not prove the hormone caused the erection problem, and a study's entry threshold is not a universal diagnostic cutoff. Diagnosis requires compatible symptoms or signs and consistently low, appropriately measured results. (Endocrine Society)

Should I get my testosterone checked if I have ED?

It is a recommended part of the assessment to discuss with your clinician. The AUA recommends morning total testosterone testing in men with ED; a low result needs confirmation rather than an automatic prescription. (AUA ED guideline, Statement 4; Endocrine Society)

Is ED a sign of heart disease?

It can be an early warning, but it does not diagnose heart disease. Ask for a cardiovascular risk assessment, which may include blood pressure, blood sugar, and cholesterol. Chest pain or trouble breathing during sex needs emergency care. (Princeton IV; Cialis label)

How long does TRT take to improve sex drive and erections?

There is no guaranteed deadline for a benefit. TRAVERSE found better sexual activity at six months and maintained benefit at two years, but no erection improvement over placebo. The Endocrine Society's response review at 3–12 months and ACP's review within 12 months for age-related low testosterone are follow-up recommendations—not instructions to wait through worsening symptoms. (TRAVERSE; Endocrine Society; ACP)

Are testosterone injections better than gel for erections?

The studies don't show a winner. TRAVERSE used gel and T4DM used injections, but they studied different men, so their results can't be compared head to head. (TRAVERSE; T4DM)

Is compounded tadalafil the same as generic Cialis?

No. Compounded tadalafil preparations are not FDA-approved finished products. FDA-approved generic tadalafil tablets are available, but the ingredient name alone does not establish approval of a particular chew, liquid, or combination. (FDA)

Does insurance cover TRT and ED pills?

It depends on the diagnosis, medicine, and plan rules. Medicare Part D excludes medicine used for ED, with an exception when it treats another FDA-approved condition. Ask separately about the consultation, tests, testosterone prescription, ED prescription, and prior authorization; do not assume a cash-pay subscription can be reimbursed. (Social Security Act §1860D-2(e)(2)(A))

Can I get TRT online if I have ED?

Possibly, after an appropriate evaluation establishes an indication and a clinician can lawfully provide that care. ED and two blood results alone do not establish suitability. Testosterone is Schedule III; the qualifying federal audio-video prescribing flexibility currently runs through December 31, 2026, with state and other requirements still applying. No program can guarantee a prescription. (Endocrine Society; Schedule III; DEA/HHS rule)

What if I'm trying to have a baby?

Get a fertility-aware opinion before choosing treatment, and discuss any current TRT with its prescriber. Testosterone can suppress sperm production, so a urologist or reproductive urologist may be the better starting point. ED medicines are a separate decision, and no option should be sold with a fertility guarantee. (Endocrine Society)

What is the right next step?

TRT and erectile dysfunction are connected, but testosterone is not a dependable erection fix. Separate the desire problem from the erection problem, confirm whether testosterone deficiency is present, and agree on how each symptom will be assessed and reviewed. Fertility plans, safety, and the real care cost can change that plan. (TRAVERSE; Endocrine Society; NIDDK)

If your testosterone is normal, focus on the erection side and your heart health. If ED showed up on TRT, get a review, not a bigger dose. And if a baby is in the plan, talk fertility first.
