How the ReVas technique has led to greater success with vasectomy reversals

An advancement in vasectomy reversal developed by Dr. Landon Trost has led to greater success for men who undergo the procedure. In fact, research showed that this technique led to men who were 8.1 times more likely to achieve a pregnancy with their partner during the first year after reversal.

This surgical technique – called Reinforcing Vasal Suture, or ReVas – was developed by Dr. Trost in 2018 while he was the Mayo Clinic’s chief of male infertility. He noted that the most common reason for a vasectomy reversal failure was due to the two tubes of the vas deferens pulling apart.

To help reach greater success for patients, Dr. Trost developed a technique where the sides of the vas deferens were also sewn together, thereby taking pressure off the ends of the traditional connection during surgery. With ReVas, the vas is able to take on more stress before any strain is placed on the microscopic surgical area.

A study in 2019 published in Translational Andrology and Urology compared both traditional and ReVas surgeries. The results were clear: men had higher peak sperm concentrations after ReVas. It also showed that total sperm counts were higher and pregnancy rates for men’s partners were also higher.

Among the stats are these:

  • Men were 7 times more likely to have > 0 sperm
  • Men were 9.9 times more likely to have > 100,000 sperm
  • Men were 11.1x more likely to have > 1 million sperm
  • Men were 12.3x more likely to have > 5 million sperm
  • Men 5.8x more likely to have > 15 million sperm
