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.
Basically, a hard thwack to the balls would do the trick.   Also, a man could stop producing sperm because â¦of a hormone imbalance, especially age related.     Men never stop making spermatazoa after the onset of puberty, as long as their testicles remain intact.
