Vasovasostomy

Q: How long after vasectomy can reversal still work?

Vasectomy reversal is possible at any time; patency exceeds 90% within 3 years and remains viable at 10–15 years, though with declining success.

Q: How do I know if vasovasostomy has worked?

Semen analysis at 6–8 weeks confirms sperm return; patency is confirmed if sperm count improves progressively over 6 months.

Q: What if no sperm are found in the reversal fluid?

Absent sperm in the testicular vasal fluid suggests epididymal blockage; vasoepididymostomy is performed on that side instead. Your consultant will provide specific guidance based on your individual clinical situation and recovery.

Microsurgical Vasectomy Reversal to Restore Natural Fertility

What is Vasovasostomy?

Vasovasostomy is a microsurgical procedure to reverse a vasectomy by re-anastomosing the two divided ends of the vas deferens under the operating microscope. Using 10-0 nylon sutures and high magnification, the vasal lumen is precisely realigned in a two-layer or single-layer closure. Success rates depend critically on the time elapsed since vasectomy — patency rates exceed 90% within 3 years and decline to 50–70% after 15+ years. Sperm quality also diminishes with time due to anti-sperm antibody formation. The procedure is performed under general or spinal anaesthesia with a hospital stay of Day Care.

Men with previous vasectomy who wish to restore natural fertility, including those who have changed partners or lost a child. Patients must be adequately fit for anaesthesia and free from active systemic infection before proceeding.

How the Procedure Works

Incision & Access

Bilateral scrotal incisions; divided vas deferens ends identified and mobilised.

Fluid Sampling

Fluid from the testicular end sampled and examined for sperm under the microscope.

Decision Point

If sperm absent from testicular end, vasoepididymostomy is planned instead.

Anastomosis

Operating microscope used; vasal lumen mucosa re-anastomosed with 10-0 nylon in a two-layer closure.

Wound Closure

Muscularis and adventitia closed in a second layer; wound closed.

Who Needs This Treatment?

→Restores natural fertility without requirement for IVF or sperm retrieval.
→Natural conception possible in 50–80% within 2 years of successful reversal.
→One-time procedure avoiding repeated TESA/ICSI cycles and their costs.
→Microsurgical precision with 10-0 suture ensures accurate mucosal alignment.
→Sperm in the reversal fluid guides immediate decision to proceed with VV or VE.
→Cost-effective long-term compared to multiple IVF cycles with ICSI.

"Vasovasostomy is one of the most satisfying operations I perform. Using the microscope to reunite a man's vas deferens and watching him father a child naturally six months later — that never gets old."
