Vasectomy Reversal: Success Rates

By Tiffany Rindels, @tiffanyrindels



Dr. Landon Trost, specialist in male infertility and andrology, discusses success rates of vasectomy reversals.

Vasectomy reversal is surgery to undo a vasectomy. Pregnancy rates after vasectomy reversal will range from about 30 percent to over 90 percent, depending on the type of procedure. When a vasectomy reversal is successful, sperm may appear in the semen within a few weeks, but it can sometimes take a year or more.

Some factors on whether a reversal is successful include:

  • Time since vasectomy
  • Partner age
  • Partner infertility

Vasectomy reversals sometimes fail if there is an underlying issue with the testicle that cannot be recognized during surgery or if a blockage develops sometime after surgery. Some men have a second-attempt vasectomy reversal surgery if the procedure does not work the first time.

This video is one of several in a series on vasectomy reversal discussing the condition, its treatment, costs, outcomes, and potential complications.
