Almost nothing. That's the instruction.
Intact care is the easiest care in pediatrics, and it gets taught wrong constantly.
Before the instructions below read as more than a preference.
The rule, in one line
Only the owner retracts his own foreskin, and only when it moves freely on its own. This is the standard position of pediatric bodies including the American Academy of Pediatrics, the Canadian Paediatric Society and the UK's NHS.
Babies and young children
Wipe the outside like you would wipe a finger, from base to tip. Water is enough. Nothing goes underneath, nothing gets pulled back, no cotton buds, no probing.
Older boys
Separation happens on its own timetable — anywhere from toddlerhood to the mid-teens is within normal range (see the separation timeline below). Once it retracts easily and painlessly, he can rinse underneath in the shower and slide it forward again.
Grown men
Retract, rinse with warm water, replace. About four seconds in a shower you were taking anyway. Skip harsh soap underneath — the inner layer is mucous membrane and detergent irritates it.
This is the single most misunderstood fact in the whole subject, and it causes real harm every year.
At birth, the inner foreskin and the glans are fused together, like a fingernail is fused to its bed. They are one continuous tissue. Over childhood, that bond separates naturally and gradually, at a pace that varies enormously between individuals. Erections during sleep, ordinary growth, and shedding of skin cells do the work.
In Øster's classic study of Danish schoolboys, full retractability rose steadily through childhood and adolescence, and true narrowing that needed treatment was uncommon by the late teens.[5] The takeaway is not the exact percentages — it is the shape of the curve.
Schematic, drawn from the shape reported in Øster (1968) and consistent with later series.[5] The point is that separation is a process with a wide normal range, not an event with a deadline.
Which is why forcing it is a mistake
Pulling back a child's foreskin before it has separated tears tissue that was never meant to come apart yet. It causes pain, bleeding, scarring — and the scarring can cause the very tightness that then gets treated as a problem requiring surgery.
- It doesn't retract. In a child, this is expected — see the separation timeline above. Physiological phimosis is a developmental stage, not a diagnosis.
- It balloons a bit when he pees. Common in young boys, usually resolving as the opening widens on its own. Worth mentioning at a routine appointment if it persists or if he is straining, but on its own it isn't an emergency.
For anything beyond this
Real problems can occur — such as paraphimosis (a retracted foreskin left stuck behind the head) or infections. yourwholebaby.org (opens in new tab) is a parent-facing resource dedicated to intact care and stays current with clinical guidance.
