Definition Return to top
Paraphimosis is the inability of an uncircumcised male to pull the foreskin back over the head of the penis.
Causes Return to top
Paraphimosis and phimosis are related conditions caused by swelling and irritation (inflammation) and narrowing of the foreskin. Causes of inflammation include:
Uncircumcised males, and those who may not have been correctly or completely circumcised, are at risk.
Paraphimosis occurs most often in children and the elderly.
Symptoms Return to top
The foreskin is pulled back (retracted) behind the rounded tip of the penis (glans) and stays there. The retracted foreskin and glans become swollen. This makes it difficult to return the foreskin to its extended position.
Symptoms include:
Exams and Tests Return to top
A physical examination confirms the diagnosis. The health care provider will usually find a "doughnut" around the shaft near the head of the penis (glans).
Treatment Return to top
Pressing on (compression of) the head of the penis while pushing the foreskin forward may reduce the swelling due to paraphimosis. If this fails, prompt surgical circumcision will be needed.
Outlook (Prognosis) Return to top
The outcome is likely to be excellent if the condition is diagnosed and treated quickly.
Possible Complications Return to top
If paraphimosis is left untreated, it can disrupt blood flow to the tip of the penis. In extreme cases, this may lead to:
When to Contact a Medical Professional Return to top

Prevention Return to top
Circumcision, when done correctly, prevents this condition.
