A brief history of men lying to their urologist

What men leave out of the ED visit, why the research says they do, and what each omission costs the workup.

Published · Last reviewed · How we review →

Nobody walks into the exam room planning to lie. What happens is smaller and more human than that. The intake form asks for "current medications" and you write down the blood pressure pill and leave off the two things from the internet. The doctor asks how often it happens and you say "sometimes," which is true in the way that "I drink socially" is true. He asks about recreational drugs and the room goes quiet for a half-second longer than it should. Then the visit is over, seven minutes in, and he is writing a prescription for a problem you described instead of the one you have. This is a page about that gap: what men leave out, why the research says they leave it out, and what each omission actually costs the workup. It ends with the part that matters, which is what to say instead.

What gets left out

Anyone who has spent years on the forums knows the list, because we have all written a version of it in a thread and then said something very different in a clinic. Roughly in order of how often it is omitted:

The real drug list

The generic sildenafil from a telehealth site that wasn't this doctor. The tadalafil that arrives in a plain envelope. The compounded troche. The bremelanotide vial. The peptide that a guy with 4,000 posts swears by. And the supplement bag: the horny goat weed, the "natural" capsule from the gas station that turns out, on FDA testing, to contain an unlabeled PDE5 inhibitor. "Current medications" on the form gets the pharmacy list. The rest stays home.

Anabolic steroids, past or present

This is the best-measured omission in the whole field. Pope and colleagues interviewed weight-lifters in 2004 and found that 56% of steroid users had never told any physician, and 40% trusted their dealer's information at least as much as their doctor's. Sixteen years later, Bonnecaze surveyed 2,385 men who used anabolic steroids and got almost the identical number: 56.1% had not disclosed, and of those who had, more than half felt discriminated against for it. The non-disclosure rate did not move in a generation.

Recreational drugs, poppers, and the actual drinking

Cocaine, MDMA, cannabis, and above all alkyl nitrites ("poppers"), which a lot of men do not think of as a drug at all and so never mention. Alcohol gets the standard social discount. None of this is moral information. All of it is pharmacological information, and one item on this list is dangerous in combination with the drug the doctor is about to prescribe.

How often it actually fails, and when

"Sometimes" covers everything from one bad night to never-firm-in-two-years. Whether morning erections still happen, whether it works solo and fails with a partner, whether it works with one partner and not another, whether there is a pattern around porn and masturbation: these are the questions that sort vascular from nerve from psychological causes, and they are the ones men most often answer vaguely.

The partner situation

Who the sex is with, whether the relationship is in trouble, whether there is a new partner or more than one, whether the problem is with men, women, or both. Doctors ask about this because context is diagnostic, and it is the question most likely to get a tidy, fictional answer.

Why: the research on withholding

The reflex is to call this shame and move on, and shame is in there. But the literature is more specific and more forgiving than that, because it turns out almost everyone does it. In the largest study of patient nondisclosure to date, Levy and colleagues surveyed two national samples totaling more than 4,500 adults and found that 81% of the younger sample and 61% of the older sample had withheld at least one type of medically relevant information from a clinician. The top reasons, in both groups: not wanting to be judged or lectured (82% and 64%), not wanting to hear how harmful the behavior is (76% and 61%), and embarrassment (61% and 50%). Read those three again. Two of them are not about shame at all. They are about not wanting to be told to stop.

That maps precisely onto the gray-market piece. Eisenberg's national survey of adults who used both conventional and complementary therapies found that 63% to 72% did not disclose at least one alternative therapy to their doctor, and the reasons were not fear. They were "it wasn't important for the doctor to know" (61%), "the doctor never asked" (60%), "none of the doctor's business" (31%), and "the doctor would not understand" (20%). Swap "alternative therapy" for "the peptide from the forum" and you have a near-perfect description of how a compounded troche or a research vial fails to make it onto the intake form: not hidden so much as filed under irrelevant, with a side of "he won't know what it is anyway."

The steroid data adds the third motive, and it is the one the forums understand best: distrust of competence. In the Pope study, users rated physicians highly on general health, smoking, alcohol, and conventional drugs, and markedly lower on anabolic steroids specifically. Bonnecaze's 2020 respondents rated physician knowledge of steroids at about 4 out of 10. When a man believes the doctor knows less about the compound than he does, disclosure feels like volunteering for a lecture from someone less informed. Whether or not that belief is fair (and in a good sexual-medicine clinic it usually isn't), it drives the silence.

Then there is the chart. Anything you say becomes part of a record that insurers, future doctors, and in some jobs an employer can see, and men on testosterone or steroids know that a documented history can complicate a later prescription, a life-insurance exam, or a fertility workup. That fear is not irrational. It is also mostly misdirected, and we will come back to it.

And finally the seven-minute visit. Under-reporting is not only a patient behavior; it is a system behavior. In the Baldwin study of 500 men over 50 visiting a urologist for something unrelated, 44% had some degree of erectile dysfunction and had not raised it. Embarrassment was the top reason (74%), but 82% of the men who had never discussed it with their primary-care doctor said they wished the doctor had asked first. Most men with the problem never get as far as a visit at all: the Shabsigh six-country analysis of more than 32,000 men confirmed that only a minority with erectile dysfunction seek treatment, with the youngest men (20 to 39) least likely, usually because they assumed it would go away. The silence starts before the door, and the room isn't built to break it.

What each omission costs the workup

Here is the part that should change your mind, because it changed ours. The AUA guideline's first statement on erectile dysfunction is that every man presenting with it should get a thorough medical, sexual, and psychosocial history, a physical exam, and selective lab testing. The history is not the preamble to the workup. It is the workup. Every test that follows is chosen, dosed, and interpreted against what you said in the first five minutes, which means every omission is not a private matter. It is a wrong input to a machine that is now going to produce a confident wrong output.

Omit the PDE5 use, mis-steer the Doppler

A penile Doppler ultrasound works by injecting a vasoactive drug and measuring the blood-flow response. The injection dose and the redosing decision are made from your history: how severe the problem is, what you already respond to, what you took recently. Understate the severity and the first dose may be inadequate, producing a false "venous leak" picture. Leave out that you took tadalafil yesterday (it lasts well over a day) and the response is read against a baseline that isn't your baseline. Either way, a test that costs real money and a needle produces a number that doesn't mean what everyone thinks it means. The same logic runs through the whole workup sequence: the history decides which tests are ordered at all.

Omit the poppers, hide the one interaction that can put you on the floor

This is the omission with the shortest fuse. The FDA label for sildenafil, and the labels for every PDE5 inhibitor after it, contraindicate nitrates in any form because the combination can drop blood pressure to unsafe levels. The patient information names the recreational versions explicitly: amyl nitrate, amyl nitrite, butyl nitrate, "poppers." A man who uses poppers and doesn't say so walks out with a prescription for a drug that has a stated, label-level danger with something already in his bedroom drawer. The doctor cannot warn about what he was not told. Same for a cardiac nitrate you forgot was a nitrate. Our PDE5 lineup page covers the drug-side of this; the history-side is you.

Omit the steroids, hide a secondary hypogonadism

Anabolic steroid use suppresses the brain's own signal to the testes, and after a cycle ends that signal can stay suppressed for months or longer. The result, reviewed by Rahnema and Lipshultz in 2014, is anabolic steroid-induced hypogonadism: low testosterone, low LH and FSH, poor libido, erectile dysfunction, and often impaired fertility. A doctor who sees a low morning testosterone with no steroid history reads it as a testicular or pituitary problem and may start standard testosterone therapy, which deepens the suppression and, if you want children, is the wrong drug entirely. Told the truth, the same doctor orders LH, FSH, and estradiol alongside the testosterone, recognizes the pattern, and manages recovery instead of masking it. Your labs only make sense with the history attached.

Omit the pattern, get the wrong "psychogenic" label

Psychogenic erectile dysfunction is a real diagnosis and a treatable one, but it is also where vague histories go to die. A young man who says "sometimes" and has a normal exam and normal labs is, statistically, going to be told it's in his head. If the actual pattern is that morning erections have disappeared, that it fails solo as well as with a partner, and that he is three months out from a steroid cycle, that label is wrong and the vascular or hormonal cause goes unworked-up. If the actual pattern is that it works fine solo and only fails with partners, that's a different and genuinely psychogenic picture, and the clinician who hears it can skip an unneeded Doppler. Both mistakes come from the same missing sentence. The history is the only tool that sorts them cheaply.

Omit the supplement bag, mislead the prescription

The FDA has issued hundreds of public notifications for sexual enhancement supplements found to contain hidden sildenafil, tadalafil, or their analogues. If you are already taking one of those and the doctor adds a prescribed PDE5 inhibitor on top, you are stacking two doses nobody counted. If a compounded product with several actives is in the mix, the same. The doctor is titrating against an invisible baseline. Our product-forms page is about learning what is actually in the thing; this is about saying so out loud.

On the chart, and on fear

The chart fear deserves a straight answer rather than reassurance. Yes, what you say gets documented. But the thing men are usually afraid of, a note that says "patient reports prior anabolic steroid use," is routine in sexual medicine and endocrinology and is precisely what makes a later testosterone prescription defensible rather than suspicious. A hypogonadism diagnosis with a documented cause is easier to treat and insure than a mystery low-T with a gap in the story. Recreational drug use is a clinical fact, not a legal report; clinicians are not law enforcement, and the confidentiality rules around your record are strong. The real exposure is the other direction: an inaccurate chart produces treatment for the wrong condition, and that follows you too.

As for the lecture: the Levy data says the thing we most want to avoid is being told to stop. Here is a reframe that the veterans of these forums eventually arrive at. You are not asking permission. You are giving the doctor the inputs to do his job on your actual body. A good clinician takes a steroid history the way he takes a smoking history, as data, and if he doesn't, you have learned something useful about whether this is your clinician. The urologist visit page walks through how to tell a sexual-medicine practice from a general one; disclosure works far better in the former, and finding one is the smart move, not the last resort.

What to actually say

The trick that works is to stop treating the visit as a conversation and treat it as a handoff. Conversations invite vagueness. Handoffs invite lists. Write this down before you go, hand it over or read it out in the first minute, and let the doctor ask the follow-ups.

The one-page history

1. Everything you take. Prescribed, telehealth, compounded, gray-market, supplement. Name, source, how long, how much, when you last took it. "I get tadalafil from an online pharmacy and I took it two days ago" is a complete sentence. "I use a compounded troche with three drugs in it, here is the label" is a better one.

2. Androgens, ever. "I ran anabolic steroids for X years, last cycle ended in month/year, I did or did not do a recovery protocol, and I want children / don't." This one sentence changes which labs get ordered.

3. Recreational, honestly. Alcohol as a weekly number, not an adjective. Cannabis, stimulants, MDMA. And poppers by name, because the doctor is about to prescribe the one drug class they are contraindicated with.

4. The pattern, not the adjective. Onset (sudden or gradual), how many attempts out of ten fail, whether morning and nighttime erections still happen, solo versus partnered, whether it varies by partner or by situation, and anything about porn or masturbation habits you suspect is part of it. Bring a score from the erectile function questionnaire; the guideline recommends validated questionnaires for exactly this reason.

5. The context. Relationship status and stress, new partner, sexual orientation, anything that has changed in the last year. Two sentences. The doctor is not grading your life; he is looking for the timeline.

If the first thing you have to say is the hardest thing, say it first. "Before we start, there are two things that aren't on the form" is a sentence that has been said in a thousand exam rooms, and in a good one it is met with a nod and a pen. If it is met with a lecture instead, you have your answer about the fit, and the directory and the telemedicine route exist for a reason.

The forums taught a lot of us to keep careful logs and a wall between the log and the clinic. The log was the right instinct. The wall was the mistake. The whole point of an honest n=1 record is that it becomes the best history any clinician has ever been handed, and the man who hands it over gets a workup built on his actual life. That is not surrender to medicine. It is using it properly.

General education, not medical advice. Nothing here is a protocol for using, combining, or stopping any drug, prescribed or otherwise. If you use nitrates or poppers, tell the prescriber before any PDE5 inhibitor is started. Decisions about testing, testosterone, and recovery from androgen use belong with a licensed clinician who has your full history, which is the whole argument of this page.

Common questions

How common is it for patients to withhold information from their doctor?

Very. In a 2018 JAMA Network Open survey of more than 4,500 US adults, 81% of the younger sample and 61% of the older sample said they had withheld at least one type of medically relevant information from a clinician. The most common reasons were not wanting to be judged or lectured, not wanting to hear how harmful a behavior is, and embarrassment.

What percentage of men with erectile dysfunction never tell a doctor?

Most. A six-country survey of more than 32,000 men found that only a minority of men with erectile dysfunction seek treatment, with men aged 20 to 39 least likely to. In a study of 500 men over 50 visiting a urologist for unrelated problems, 44% had some degree of erectile dysfunction they had not raised, and embarrassment was the top reason (74%).

Do I have to tell my urologist about steroid use?

You should, because it changes the diagnosis. Anabolic steroids suppress the brain's signal to the testes, and a low testosterone result without that history can be read as a different condition and treated with standard testosterone therapy, which deepens the suppression and impairs fertility. With the history, a clinician orders LH, FSH, and estradiol alongside testosterone and manages recovery instead. Surveys in 2004 and 2020 both found that about 56% of steroid users had not told a doctor.

Why does my doctor need to know about poppers before prescribing sildenafil or tadalafil?

Because poppers are nitrates, and every PDE5 inhibitor label contraindicates nitrates in any form. The combination can drop blood pressure to unsafe levels. The FDA patient information for sildenafil names amyl nitrate, amyl nitrite, and butyl nitrate (poppers) specifically. A doctor cannot warn about an interaction with a substance he was not told about.

Can an incomplete history lead to a wrong diagnosis of psychogenic ED?

Yes. A vague history plus normal labs and exam often ends in a psychogenic label. If the real pattern includes lost morning erections, failure both solo and with a partner, or recent steroid use, that label is wrong and a vascular or hormonal cause goes unexamined. If the real pattern is that function is fine solo and fails only with partners, that points toward a psychogenic picture and can save an unneeded Doppler test. The history is what sorts the two.

What should I actually tell my urologist about erectile dysfunction?

Bring a written list: everything you take (prescribed, telehealth, compounded, gray-market, supplements) with source and last dose; any anabolic steroid use, ever, with dates; alcohol as a weekly number plus any recreational drugs including poppers; the pattern (onset, how many attempts fail, morning erections, solo versus partnered); and relationship context. Say the hardest item first. A good sexual-medicine clinician treats it as data, not a confession.
