Blood flow before and after varicocele surgery
Part of Heart & circulation, Kidney & urinary clinical trials.
This study looks at how the amount of blood flowing backward in the veins affects sperm health before and after a surgery to fix varicocele. It aims to see if the surgery improves sperm count and quality in men with varicocele on both sides.
