An orchidectomy is a surgical procedure that involves the removal of one or both testicles. There are several reasons why a man might have this operation, such as cancer, injury, or trauma to the area. Regardless of the reason, the effects of this surgery on a manâs sex life depend on the number of testicles removed. When one testicle is removed, there is usually no effect on a manâs sexual function.
Some reasons why testicles get smaller are: 1  If a man takes testosterone, the testicles do not have to work to make testosterone, so they become smaller. 2  If a man's testicles are kept more warm than usual, they make less sperm. 3  If testicles are injured(hurt) they can become smaller.
