Varicocele

Enlarged veins in the scrotum that can impair sperm production.

Male fertility

Varicoceles are common and often harmless, but a clinically palpable varicocele with abnormal semen parameters may be treated surgically or by embolisation. Improvement in semen parameters is common; improvement in live birth is less certain, so the decision is individual.

Also known as: varicose veins in scrotum, varicocoele
