Of the half a million men who have a vasectomy each year, 2 percent to 6 percent of them — 10,000 to 30,000 men — later decide to have the vasectomy reversed. This surgery reconnects the ducts that carry sperm from the testicles into the semen. After a successful vasectomy reversal, sperm are present in your semen again and you may be able to get your partner pregnant.
Men decide to have the surgery to restore fertility for a number of reasons, including loss of a child, remarriage, or improved finances. A small number of men have a vasectomy reversal to treat testicular pain.
