Summary

This study looks at 100 men with varicoceles (enlarged veins in the scrotum) to see if the amount of backward blood flow affects sperm quality. Participants will have ultrasound and semen tests before and 3 months after varicocele repair surgery. The goal is to better understand which patients might benefit most from the operation.
