Many men put off asking about urinary or sexual health — sometimes out of embarrassment, sometimes because they assume it's just part of getting older. The cost of that silence shows up in the data: in Singapore, prostate cancer is now among the most common cancers in men, accounting for roughly one in six male cancer cases — yet only about 15% of cases between 2018 and 2021 were caught at Stage I, while around 31% were picked up at Stage IV, according to the Singapore Cancer Registry.1
That pattern repeats across men's health: conditions that are very manageable when raised early, discovered late because the question felt too awkward to ask. So we put the ten most-avoided questions to a urologist — and grouped the answers into three themes, so you can scan for the one that's been sitting in the back of your mind.
- 01 How many times is too many to pee at night?
- 02 When should men start prostate checks?
- 03 Why does the urine stream get weaker with age?
- 04 Can holding urine for hours damage the bladder?
- 05 Does ejaculating more often lower prostate cancer risk?
- 06 Does cycling really affect erections?
- 07 Is a morning erection a sign of good health?
- 08 Does a vasectomy lower testosterone or affect performance?
How many times is too many to pee at night?
Quick answerOnce a night can be normal. Twice or more, night after night, deserves a check.
One trip a night — especially after a late dinner, tea, or alcohol, is usually nothing. What matters is the pattern. Waking two or more times every night is worth a medical evaluation,2 because the causes range widely: an enlarging prostate, diabetes, even a sleep disorder. Each is treatable, but only once it's named.
"If night urination is becoming a pattern, get it checked. Better sleep starts with knowing the cause."— Dr Joe Lee
When should men start prostate checks?
Quick answerFrom 50 for most men — from around 40 if your father or brother had prostate cancer before 60.
Men aged 50 and above should discuss prostate screening with their doctor. If there's a family history of prostate cancer diagnosed before 60, that conversation should start around age 40.3 And if it's the famous physical exam putting you off: modern assessment often relies on blood tests, urine tests, scans, and MRI — not just the part everyone jokes about.
Why does the urine stream get weaker with age?
Quick answerOften an enlarging prostate — it affects roughly half of men in their fifties. But it's not the only cause.
Benign prostatic hyperplasia (BPH) — non-cancerous enlargement of the prostate, affects roughly half of men aged 51 to 60,4 and as the prostate grows it narrows the tube urine passes through. But a weakening stream can also point to an infection, a narrowing of the urethra, or a weakening bladder, which is why it deserves a proper look rather than a shrug.
"If your stream is getting weaker, you're straining, or you feel you cannot empty properly, it is worth checking."— Dr Joe Lee
Can holding urine for hours damage the bladder?
Quick answerOccasionally, no harm done. As a daily habit, yes — it strains the bladder muscle.
Holding it through the occasional long meeting or road trip carries minimal risk. The trouble is when it becomes routine: a bladder that's regularly overstretched can develop discomfort, control problems, and a higher risk of infection.
"Don't panic if it happens once in a while. But don't train your bladder to suffer every day."— Dr Joe Lee
Does ejaculating more often lower prostate cancer risk?
Quick answerOne large study suggests a link — but it's no substitute for actual screening.
A 2016 study in European Urology found that men reporting 21 or more ejaculations a month had roughly a 20% lower risk of a prostate cancer diagnosis than men reporting four to seven.5 It's an association, not a guarantee — and not a health plan.
"It does not mean ejaculation is a guaranteed way to prevent prostate cancer. Don't treat it as a substitute for proper health checks."— Dr Joe Lee
Does cycling really affect erections?
Quick answerNot automatically. Long hours on a narrow saddle can press on nerves and vessels — the fix is usually equipment, not quitting.
Cycling doesn't damage erections by default. The issue is extended time on a narrow saddle, which can put pressure on the nerves and blood vessels of the perineum. Most of the risk is engineered away with a properly adjusted saddle, padded cycling shorts, and regular breaks out of the seat.
"Adjust the saddle, take breaks, and use proper cycling shorts. If the problem persists, see a doctor."— Dr Joe Lee
Is a morning erection a sign of good health?
Quick answerBroadly, yes — and a change in erection quality is information your doctor should hear.
Morning erections suggest the nerves and blood supply involved are doing their job. What matters more is change: research shows erectile dysfunction can precede the symptoms of coronary artery disease by two to five years,6 because the arteries involved are smaller and show trouble sooner. A quiet change in this department is worth a conversation, not just for your sex life — for your heart.
"Erection health is not just about sex. It reflects general health too."— Dr Joe Lee
Does a vasectomy lower testosterone or affect performance?
Quick answerNo. It blocks sperm transport only — hormones, libido, and performance are untouched.
A vasectomy blocks the tubes that carry sperm. That's all it does. The testes continue producing testosterone and releasing it into the bloodstream exactly as before, which is why the procedure has no effect on erections, sex drive, or performance. The myth persists; the anatomy disagrees.
Blood in the urine — when should I worry?
Quick answerAlways. Even once. Even without pain.
This is the one answer with no nuance. Visible blood in the urine is the most common first symptom of bladder cancer,7 and it often appears once and then disappears for weeks — which is exactly how it gets dismissed. Painless doesn't mean harmless.
"Even if the blood appears only once, even if there is no pain, you should still get it checked."— Dr Joe Lee
How do men check for testicular cancer?
Quick answerA monthly self-check after a warm shower — and any new lump gets seen, promptly.
Once a month, after a warm shower when everything is relaxed, gently roll each testis between your fingers and feel for anything new — a lump, a hard area, a change in size. Testicular cancer most commonly affects men aged 15 to 35, and when caught early the five-year survival rate is above 95%.8 Few cancers reward early detection so generously.
"Not every lump is cancer. But any new lump should be checked."— Dr Joe Lee
The thread that ties all ten
Run back through the list and a single pattern emerges: almost everything here — an enlarging prostate, a changing stream, blood that appears once, a lump found in the shower, is dramatically more manageable when raised early. The barrier is rarely medical. It's the asking.
That's also why continuity matters. A doctor who knows your baseline — your usual pattern, your last PSA reading, your family history, is far better placed to spot the change that matters than one meeting you for the first time at the emergency stage.
The takeaway
If one of these ten questions has been sitting in the back of your mind, consider this your prompt to ask it out loud. None of them gets more awkward by being asked early — only by being asked late.
