Phimosis is the inability to retract the foreskin covering the head of the penis. There are two different types of phimosis: physiologic and pathologic. Physiologic phimosis occurs when children are born with a tighter foreskin. This form of phimosis usually resolves on its own over time between the ages of 5-7 years. However, the age can be a bit older depending on each specific case. Pathologic phimosis occurs when there is trauma from scarring, infection, and inflammation.
