Can some one with knowledge and experience on this please help me figure out what is happing to me .
when i was 18 i went to the doctors because i was feeling pains in my groin .i went to the hospital and i was told by the doctor ( the same man who did the varicoelectomy surgery on me)that i had varicose veins. i have noticed those veins but they never bothered me until then . I was very nervous and i wanted to be cured from the pain and i feel as if i rushed into the surgery.He performed the operation to both sides of my testicles. My sperm count was never tested before the surgery. after the surgery i immediately noticed that my sperm changed drastically . it went from being white sticky and dense to looking like water and pre-***. my sperm is not sticky at all anymore there is only a little whiteness . i feel as if this surgery has made me infertile . i later went to the same hospital to get a sperm count they told me is was 50 percent chance that i can impregnate a women . IM not really sure what that means but i don't trust that doctor anymore . if my body is producing less sperm now how will this effect the testosterone in my body ? will this cause be to have less drive or less strength?(like a dog that has been neutered or something) because sometimes i be feeling so down .Now that time has past i feel as if i never needed surgery in the first place . im realizing at the time when my groin first started hurting i was gaining a lot of weight and my cloths started to fit tighter causing my groin to hurt . i feel that that was the reason why that happened to me . when get and erection i feel pain and discomfort at . some time my left testicle gets sucked into my body and it causes pain . i don't know what to do anymore .is there anyway to undo the operation ? im 22 now and i fear that as i age this will only get worse . please any advice and suggestions would by greatly appreciated
