What are the common treatments for varicocele?

Doctor's answer:

Varicocele can cause local discomfort, manifesting as a heavy and pulling pain in the scrotum, which is more pronounced during standing and movement and can be alleviated by lying down. It can also lead to neurasthenia accompanied by the patient's worry and anxiety, resulting in emotional instability, fatigue, and neurasthenia, among other symptoms. Varicocele can cause infertility and testicular atrophy.
The treatment of varicocele can be conservative for mild cases, involving rest, wearing tight underwear, reducing strenuous exercise, and appropriately using blood-activating medications. However, moderate to severe cases, or those accompanied by infertility or abnormal semen, require surgical intervention.
