Vasectomy Reversal: Restoring Fertility After Vasectomy
A vasectomy reversal is a microsurgical procedure performed to restore the flow of sperm through the vas deferens after a vasectomy. This allows men to regain natural fertility and the possibility of fathering children without assisted reproductive technologies.
What Is a Vasectomy Reversal?
During a vasectomy, the vas deferens — the tubes that carry sperm from the testicles — are cut or sealed. A reversal reconnects these tubes, allowing sperm to once again be present in the semen. The procedure is typically performed by a urologist with specialized training in microsurgery.
There are two main techniques:
- Vasovasostomy: The severed ends of the vas deferens are reconnected directly.
- Vasoepididymostomy: Used when there is a blockage or damage near the epididymis, this more complex procedure connects the vas deferens directly to the epididymis.
The choice of method depends on factors assessed during surgery, such as the presence of sperm in the fluid from the vas deferens.
Success Rates and Considerations
Success rates vary depending on the time since the original vasectomy, the patient’s age, and the surgeon’s expertise. In general:
- The highest success rates are seen when the reversal is performed within 10 years of the vasectomy.
- Return of sperm to the semen occurs in approximately 70–90% of cases.
- Pregnancy rates after reversal range from 30–60%, depending on additional factors such as the age and fertility of the partner.
