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.
Vasectomy is a form of birth control for men that is meant to be permanent. During vasectomy, a health care provider closes or blocks the tubes that carry sperm. When the tubes are closed, sperm cannot leave a man's body and cause pregnancy. Sperm are made in the testicles. They pass through two tubes called the vasa deferentia to other glands and mix with seminal fluids to form semen.
