Phimosis (from Greek φίμωσις phimōsis 'muzzling'[9][10][11]) is a condition in which the foreskin of the penis cannot stretch to allow it to be pulled back past the glans.[3] A balloon-like swelling under the foreskin may occur with urination.[3] In teenagers and adults, it may result in pain during an erection, but is otherwise not painful.[3] Those affected are at greater risk of inflammation of the glans, known as balanitis, and other complications.[3]

In young boys, it is normal not to be able to pull back the foreskin at all.[7] Over 90% of cases resolve by the age of seven, although full retraction is still prevented by preputial adhesions in over half at this age.[5][7] Occasionally, phimosis may be caused by an underlying condition such as scarring due to balanitis or balanitis xerotica obliterans.[5] This can typically be diagnosed by seeing scarring of the opening of the foreskin.[5]

Typically, the condition resolves without treatment by the age of 18.[4] Efforts to pull back the foreskin during the early years of a young male's life should not be attempted.[7] For those in whom the condition does not improve further, time can be given or a steroid cream may be used to attempt to loosen the tight skin.[7] If this method, combined with stretching exercises, is not effective, then other treatments such as circumcision may be recommended.[7] A potential complication of phimosis is paraphimosis, where the tight foreskin becomes trapped behind the glans.[5]
