The vasectomy reversal risk of surgical infection is less than 1%. Dr. Turek gives a single dose of antibiotics 1 hour before the procedure to minimize this. An infection may require oral antibiotics, or in its most serious form, intravenous (by vein) antibiotics and hospitalization. Fevers and increased scrotal discomfort are clues that this may be happening. The risk of an infection of the surgical incision is more rare (less than 1%) but may also require antibiotics. During or after vasectomy reversal, when a small amount of sperm and fluid leaks out of the reconnected site, it may induce an inflammatory reaction termed a granuloma (risk less than 1%) that may be painful, but usually resolves with time. Rarely this will disrupt the reconnection.
Failure of the vasectomy reversal to produce a sperm count in the ejaculate is a risk but not a complication. This is an unfortunate outcome and can be due to
- 1) poor sperm production with a correctly performed vasectomy reversal procedure or
- 2) normal sperm production and a technical issue (reconnected site has scarred down) or judgment issue (needed an epididymovasotomy instead of a vasovasostomy) with the vasectomy reversal procedure.
