Recovery from a vasectomy reversal probably takes about one week. You’ll be able to go back to work within a few days. I know, not what you want to hear, but even after that, you’ll be advised to limit some of the activities that cause excessive movement in your testicles. Primarily the scrotal area, as this could really pull on that anastomosis of the vas. Ironically, you’ll actually be asked to abstain from sexual activity by your physician until they give you the okay.
