A condition in which a tight foreskin can't be pulled back over the head of the penis.

Phimosis is typical in newborns and young children. Often, it goes away on its own by age 5. In adults, phimosis can raise the risk of urinary tract infections, penile cancer, HIV and sexually transmitted infections.

Phimosis symptoms can include swelling, tenderness, pain during urination, weak urine flow, blood in urine, urinary tract infections, painful erections, and bleeding or a thick discharge from under the foreskin.

Phimosis treatments can include steroid creams or gels to make the foreskin softer. Antibiotics can treat infections caused by germs. Surgery may be needed to remove the foreskin or to make the foreskin easier to pull back.
