About six weeks after surgery, your doctor will examine your semen under a microscope to see if the operation was successful. To collect a semen sample, your doctor will have you masturbate and ejaculate into a container.

Your doctor may want to check your semen every two to three months. Unless you get your partner pregnant, checking your semen for sperm is the only way to tell if your vasectomy reversal was a success.

When a vasectomy reversal is successful, sperm usually appear in the semen after a few months, but it can sometimes take a year or more. When successful, vasectomy reversal usually leads to pregnancy within two years. The likelihood for success depends on various factors, including the length of time which passed since the vasectomy and the female partner's age.

If vasectomy reversal doesn't work

Vasectomy reversals sometimes fail if there is a sperm blockage that wasn't recognized during surgery, or if a blockage develops sometime after surgery. Some men have a second-attempt vasectomy reversal surgery if the procedure doesn't work the first time.

You may also be able to father a child through in vitro fertilization by using frozen sperm retrieved during a semen analysis during your vasectomy reversal. If you didn't have sperm frozen or you do not have any sperm in your ejaculate, in vitro fertilization may still be possible using sperm retrieved directly from your testicle or epididymis.
