While vasectomy reversal boasts an impressive 90-95% success rate overall, the chances of restoring sperm flow dramatically decrease from 96% to just 74% depending on how many years have passed since the original procedure.
Key Takeaways

- Pregnancy rates after vasectomy reversal average 52% overall
- Live birth rate of 76% if reversal within 3 years of vasectomy
- Pregnancy rate 30-75% depending on obstructive interval, highest <5 years
- Intraoperative complications occur in 1-2% of vasectomy reversals
- Hematoma formation rate is 1.7% post-reversal surgery
- Wound infection risk is 0.5-2% with prophylactic antibiotics
- Average operative time for bilateral vasovasostomy is 2.5-3.5 hours
