Vasectomy is a safe, effective, and permanent method of birth control for men. It is also the most cost-effective form of birth control, costing half as much as a tubal ligation (having a woman's "tubes tied"). A successful vasectomy will last for life, but if circumstances change, the procedure can be reversed. In this podcast, I'll discuss how the initial procedure is carried out and exactly how the surgery can be undone, as such. I'll also examine the reasons for infertility even after a vasectomy reversal.
