Will having varicose veins for 1 month, affect my testosterone and sperm? im still in pain, i cant do any activity and hurts when aroused or testicles are close to body?

No, it should not affect in the long term if the condition is mild.

Varicose veins can cause discomfort in the scrotum and seldom cause the symptoms you mention. If you continue to hurt pl see a Urologist. In the meantime wear a good scrotal support and use local heat. It does not affect testosterone and affects sperm counts only if of long duration- and then not in everyone. hope you feel better
