Success Rates

Several factors affect the chances of success including:

  • surgical technique and quality of reversal operation
  • surgical technique of original vasectomy
  • time elapsed since vasectomy
  • presence of antisperm antibodies

Success is generally defined as the presence of viable spermatozoa in a postoperative semen sample. There is a steady decline in success rate as the time since the vasectomy increases.

The success rate in Mr Swinn’s series approaches 90%
. For those whose vasectomy was carried out within the previous 4 years of the reversal operation, the success rate is higher than 90%. Although the success rate declines with the passage of time since the vasectomy, stunning successes have been achieved at The Vasectomy Reversal Clinic for those undergoing a microsurgical reversal of vasectomy even close to 20 years after the vasectomy.
