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.
Testes secrete the male hormone testosterone. The testes secrete testosterone, which is necessary for proper physical development in boys. In adulthood, testosterone maintains libido, muscle strength, and bone density. Disorders of the testes are caused by too little testosterone production. The testes (or testicles) are a pair of sperm-producing organs that maintain the health of the male reproductive system. The testes are known as gonads. Their female counterpart are the ovaries.
