Dear Twisted, Varicocele, or varicose veins that surround the testis, are simply abnormally distended veins. The usual cause of varicocele is failure of the testicular valves. The condition is usually harmless, though there may be an aching discomfort in the scrotum.
Diagnosis is confirmed by examination of the scrotum.
The condition may be relieved by wearing an athletic support. Further treatment is not usually necessary. However, if you and your partner are trying to get pregnant and are having trouble, it is possible that the varicocele may be affecting your fertility. The varicocele can cause your sperm count to be low, or your sperm to be abnormal in shape or motion, as it sometimes applies excessive heat and pressure to the testes. If you and your partner are not trying to get pregnant, there shouldn't be any cause for concern.
