Phimosis and Paraphimosis

What is phimosis and paraphimosis?

Phimosis is a constriction of the opening of the foreskin so that it cannot be drawn back over the tip of the penis. This condition is a normal occurrence in the newborn boy, but over time the skin that adheres to the tip of the penis can be retracted as the foreskin loosens. By age 3, 90 percent of uncircumcised males should be able to completely retract their foreskin from the tip of the penis. By age 17, 97 to 99 percent of males will be able to completely retract their foreskin. Phimosis can also occur if the foreskin is forced back before it is ready. This can cause a fibrous scar to form, which may prevent future retraction of the foreskin.

Paraphimosis occurs when the foreskin is retracted behind the corona (or crown) of the penis and cannot be returned to the unretracted position. This can cause entrapment of the penis, impairing the drainage of blood, and may be serious.
