My sweat glands seem to be completely shut down. I’m 34, and have been experiencing this problem for about 2 years now (don’t know if its related). My left testicle is the only one that sweats and it’s very noticeable and looks like a deformed yellowish ball (about the size of a marble). I’ve had blood tests done which indicated no abnormalities, but my doctor doesn’t want to do surgery because he thinks it will make me infertile later on in life. Is there any way to fix this? What causes this kind of sweating? How can I prevent further problems with my balls by avoiding heat or cold exposure? Any help would really be appreciated!
