Phimosis and Paraphimosis: A Patient Guide

Overview

Phimosis and paraphimosis are two related conditions that affect the foreskin, the loose skin covering the tip (glans) of the penis. Phimosis occurs when the foreskin is too tight to be pulled back over the glans, which is common in infants and young boys but can also affect teens and adults. Paraphimosis is a less common but urgent condition that happens when the foreskin is pulled back behind the glans and cannot be returned to its normal position, which can restrict blood flow to the penis if not treated quickly.

Signs & Symptoms

Symptoms vary depending on which condition you have. For phimosis, you may notice difficulty or pain when trying to retract the foreskin, swelling or redness of the foreskin, or problems with urination (such as a weak stream or dribbling). In some cases, phimosis may not cause any symptoms at all. For paraphimosis, symptoms come on suddenly and include a tight, painful foreskin stuck behind the glans, swelling of the glans, discoloration (pale or bluish skin), and difficulty urinating. If left untreated, paraphimosis can lead to permanent tissue damage.

Causes & Risk Factors

Phimosis is usually a normal part of development in young boys, as the foreskin naturally separates from the glans over time. In teens and adults, phimosis can be caused by scarring from repeated infections (balanitis, inflammation of the foreskin and glans), skin conditions like eczema or psoriasis that affect the penis, or trauma to the foreskin. Paraphimosis is almost always caused by forcibly retracting the foreskin, or by the foreskin getting stuck during sexual activity, masturbation, or a medical exam. Risk factors for both conditions include poor genital hygiene, frequent balanitis, and having a naturally tight foreskin from birth.

Diagnosis

Most of the time, a healthcare provider can diagnose phimosis or paraphimosis with a physical exam and a review of your symptoms. They will look at the foreskin and glans to check for tightness, swelling, or scarring. In some cases, they may take a swab of the foreskin to test for infections like balanitis, or order blood tests if they suspect an underlying skin condition. No special imaging or lab tests are usually needed for a diagnosis.

Treatment & Management

Treatment depends on the condition and how severe it is. For mild phimosis, at-home gentle foreskin stretches (done slowly and without force) and improved hygiene are often enough. For more persistent phimosis, a healthcare provider may prescribe a topical steroid cream to soften the foreskin and make stretching easier. If these treatments don’t work, a minor surgical procedure called circumcision (removal of the foreskin) may be recommended. For paraphimosis, immediate treatment is needed: a provider will manually push the foreskin back into place, sometimes with a local anesthetic to reduce pain. In severe cases, a small incision may be made to relieve pressure, or circumcision may be done to prevent the condition from happening again.

Living With It

If you have phimosis, practicing good genital hygiene (gently washing under the foreskin with warm water daily) and avoiding forceful retraction can help prevent symptoms from getting worse. For people with recurrent phimosis, circumcision is a permanent solution that eliminates the risk of the condition returning. After treatment for paraphimosis, follow your provider’s instructions for caring for the area, and avoid forcibly retracting the foreskin in the future to prevent recurrence. Most people recover fully from both conditions with proper treatment.
