Erectile dysfunction as an early warning: blood flow, not hormones
Urologists Michael Eisenberg and Rena Malik say most erectile problems come from blood vessels and the pelvic floor and often appear before heart disease does, and Kelly Starrett and Kyle Gillett add the movement and lifestyle side. Men who treat it as a health signal get a chance to fix the cause early.
Erection trouble is usually a blood flow problem, not a hormone problem, and it can be an early warning about the heart and blood vessels. The shared conclusion of the four clinicians here is to treat the symptom as a reason to get checked and to fix what feeds it, even though the pills work. This reports what they said. Any man with these symptoms should see a doctor.
Stanford urologist Michael Eisenberg says over half of men past 40 have some trouble with erections, and that hormonal causes are a small share, probably around 5 percent. The usual causes are the ones that damage blood vessels anywhere: high blood pressure, diabetes, lifestyle and obesity. The penile arteries are only about a millimeter across, so they can show disease before the larger arteries of the heart do. Asked whether a man whose erections are fixed by a pill still needs checking, he answers: "Well, I think they should be screened." He sends patients for blood pressure, lipid levels and fasting blood glucose.
Urologist Rena Malik puts hormonal cases at about 3 percent. Testosterone drives desire, she explains, which is separate from the body's response. She cites a figure that about 15 percent of men who develop erectile dysfunction have a cardiovascular event within seven years. In men in their 20s and 30s she more often finds a tense pelvic floor, long hours of sitting and anxiety, and she says "exercising one hour is not going to offset the day full of sitting". A key question is whether a man gets erections at night, which shows the organ itself works.
Physical therapist Kelly Starrett describes the movement side, with one anecdote of a friend whose erections improved after hip work. Hormone physician Kyle Gillett calls erectile dysfunction the canary in the coal mine, since the same plaque can build in the coronary arteries. He still orders labs every time.
They agree that hormones are a small part, that the symptom is a signal about the heart and vessels, and that Kegels are not the answer by default. Some men need to strengthen the pelvic floor and many need to relax it, and only an assessment tells which. Lifestyle comes first, and the drugs, which help 60 to 70 percent of men, are still good.
They differ on how much is physical. Eisenberg says most cases are organic, while Gillett says a test of sleep erections is normal in about 90 percent of cases, pointing to a situational cause. The sources do not reconcile this, though the patients each sees may differ. They also give different figures on cycling and on heavy lifting.
There are limits. The vascular warning fits best for men with risk factors and gradual onset, and Eisenberg takes care not to be alarmist. Hormones still deserve a test. Starrett's evidence is one text message. And an erection lasting more than four hours without arousal is an emergency that needs an emergency room.
What to do with it: see a doctor and ask for the vascular basics, even if a pill has fixed the symptom. Notice whether you get erections during sleep. Get hormones measured but do not start there. Stop nicotine in every form. Sit less across the whole day. Do not start Kegels on your own. Breathe when you lift. If you cycle and feel numbness, change something. And ask about medication without embarrassment.
