Varicocele is a condition characterized by enlarged veins within the scrotum. It is one of the most common reversible causes of male infertility.
The condition occurs when valves in the veins fail to function properly, causing blood to accumulate and increase temperature in the testicular area. Elevated temperatures can interfere with sperm production.
Varicocele often develops during puberty and may remain unnoticed for years. Symptoms may include scrotal discomfort, visible enlarged veins, or infertility.
Treatment typically involves a surgical procedure called varicocelectomy, which improves blood flow and may enhance erotic sperm production.
