Can vasectomy or tubal ligation sometimes be reversed?

Yes, both vasectomy and tubal ligation can sometimes be reversed, though they are intended to be permanent forms of contraception.31

Vasectomy Reversal

A vasectomy involves severing the vas deferens to prevent sperm from being ejaculated. Reversal is performed using standard or microsurgical techniques to reconnect the tubes. While success rates for reconnecting the cords are often cited as at least 40 percent to 80 percent, the actual rate of successful conception following reversal can be lower. If surgical reversal is unsuccessful, sperm can sometimes be harvested for in vitro fertilization.23

Tubal Ligation Reversal

Tubal ligation involves closing or blocking the fallopian tubes. Reversal is difficult, expensive, and has limited success. The likelihood of success depends heavily on the initial method used; for example, techniques involving clips or bands are generally less destructive to the tubes and may have higher reversal rates than methods involving electrocautery or the removal of tube segments. Even when a reversal procedure is technically successful, other damage from the original sterilization may prevent pregnancy.3
