Forcible retraction will tear the synechia so should be avoided. 2) Nature provides a second method is provided to prevent retraction by making the tip of the immature foreskin too narrow to pass over the [[glans penis]]. The tip One-half of the [[foreskin]] normally widens to render the foreskin retractable boys can retract by 10.4 years of age 18, but a few persist the others do not become retractable until later. <ref>{{REFjournal |last=Thorvaldsen |first= |init=MA |author-link= |last2=Meyhoff |first2= |init2=HH |author2-link= |etal=no |title=Patologisk eller fysiologisk fimose? |trans-title= |language=Danish |journal=Ugeskr Læger |date=2005-04-25 |volume=167 |issue=17 |pages=1858-62 |url=https://www.cirp.org/library/normal/thorvaldsen1/ |archived= |quote= |pubmedID=15929334 |pubmedCID= |DOI= |doi= |accessdate=2025-10-29}}</ref>  Continued physiological phimosis with non-retractable foreskin into adult life is a normal variant.
