Changes

Boys are born with a non-retractile foreskin.<ref name="agarwal2005" /> The [[foreskin]] gradually becomes retractable over a variable period of time ranging from birth to 18 years or more.<ref name="Øster1968"/><ref name="thorvaldsen2005"/> There is no “right” age for the foreskin to become retractable. Non-retractile foreskin does not threaten health , so no intervention is necessary. Many boys only develop a retractable foreskin after [[puberty]]. Education of concerned parents usually is the only action required.<ref>{{REFjournal
