Men's Health Alert: Skipping Post-Urination Wiping Raises Infection Risk
Medical experts are issuing a stark warning to men about the dangers of neglecting a simple bathroom habit, following a surge in viral online debates. The discussion, sparked by viral videos with millions of views, centres on whether men should use toilet paper after urinating. This trend highlights a widespread issue, with YouGov polling revealing that more than a third of men admit they never wipe after urinating.
The Hidden Dangers of Poor Urinary Hygiene
Doctors emphasise that skipping this step is not merely unhygienic or a potential cause of odour; it can significantly increase the risk of painful infections. Professor Christopher Bunker, a consultant dermatologist specialising in male genital dermatology, provides clear guidance: 'The best advice for men when urinating is to pass urine with the foreskin fully retracted, empty the bladder, then gently squeeze the penis a few times to expel any remaining urine. After that, dry the area with dry toilet tissue – not wet wipes.' He cautions against wet wipes due to the chemicals they contain, which can trigger allergic reactions on sensitive skin.
Consequences of Residual Urine Build-Up
Failing to properly dry the area can lead to a harmful accumulation of bacteria. Professor Bunker states there is now strong evidence that retained urine on the penis is a causative factor for several conditions, including:
- Lichen sclerosus
- Thrush
- Dysuria (painful urination)
- Tightening of the foreskin
- Penile cancer
Men's health specialists explain that residual urine creates a warm, damp environment under the foreskin, ideal for bacteria and yeast to thrive. One of the most common resulting conditions is balanitis – inflammation of the head of the penis. This affects an estimated three to 11 per cent of men and is more prevalent in those who are uncircumcised.
Understanding the Root Causes
Dr Jeff Foster, a GP specialising in men's health, clarifies: 'Failure to expel the last part of your urine can result in a small build-up under the foreskin, leading to balanitis, which is effectively an infection.' While not wiping is not always the direct cause, it significantly elevates the risk. Balanitis is typically driven by a combination of moisture, irritation, and microbial overgrowth, with sweat and leftover urine both contributing.
Men experiencing post-micturition dribbling (PMD) – involuntary leakage after finishing – are particularly vulnerable. This condition is more common in men over 50, with studies suggesting up to 63 per cent are affected, often due to a weakened pelvic floor.
The Importance of Correct Technique
Experts point to poor technique as a frequent culprit. Professor Bunker notes that many men have never been taught the correct method: 'The reality is that the male urinary system isn't perfect – we don't have a 'tap' that completely shuts off at the end. There is often some residual leakage, even in men who think they are being careful. Many men are surprised to learn that it is not normal to be unable to retract the foreskin.'
In rare instances, bacterial build-up may contribute to urinary tract infections, though Dr Foster notes this is extremely uncommon in his clinical experience.
Serious Long-Term Health Implications
If balanitis is left untreated, it can develop into a chronic condition known as lichen sclerosus. This can cause intense itching, burning, soreness (especially during or after sex), tightening of the foreskin leading to painful erections, and skin that tears or bleeds. It may also affect urine flow. Treatment options include circumcision and potent steroid creams, though these are not always fully effective.
The British Association of Dermatologists recommends drying the penis after urination to mitigate risk. While lichen sclerosus is rare, affecting roughly 0.07 per cent of men, awareness is vital. Professor Bunker stresses that early diagnosis and proper preventive habits can lead to remission, describing it as 'a very, very nasty disease' that requires lifelong management.
