Men's Sex Myths: Does Vasectomy Cause Testosterone Deficiency?

Vasectomy is a minor surgical procedure used for permanent birth control. A vasectomy simply stops the flow of sperm from the testicles to the urethra. It does NOT affect testicular function. The testicles continue to produce testosterone at the same rate. So, this myth is very easy to bust. A vasectomy will NOT change your testosterone level. Furthermore, it will not change your sexual function in any way, shape or form!
