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 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.
