You might also ask a urologist whether you have a hydrocele in the larger testicle. A hydrocele is a sac of water in or on the testicle that causes the entire structure to enlarge. It's not life-threatening, and it can be repaired. It's thought to be congenital, and is not related to self-abuse. But unless the repair is done correctly the first time, it can mean further procedures in the future, one of which may be a vasectomy that you might not want, especially if you're young and would like to father children later.View Thread
