Two Methods of Reversal
The primary objective of reversing a male vasectomy is to rejoin the vas deferens tube so the sperm can reach the semen and ejaculate outwardly during orgasm. There are two methods of doing this: a vasovasostomy and a vasoepididymostomy. During a vasovasostomy, the surgeon will sew the vas deferens tube from the testes to the penis back together; this is a straightforward reversal of the original procedure if it is able to work. A vasoepididymostomy is more difficult and is used only if a vasovasostomy is unlikely to work. In this process, the surgeon will attach the vas deferens tube to the small organ at the back of each testicle that houses sperm.
