A varicocele is a dilatation of the pampiniform venous plexus within the scrotum. Approximately 15-20% of the healthy fertile male population is estimated to have varicoceles; however, 40% of infertile men may have them. How a varicocele impairs sperm structure, function, and production is unknown, but researchers believe it interferes with testicular thermoregulation.
