Vasectomy Reversal Success Depends on Three Big Things…Read On!

The three things…The surgeon, the quality of fluid at the time of the procedure, and the years since the vasectomy…and a little luck.

Time to Sperm Appearance Can Be Predicted After Vasectomy Reversal

Urology – November 30, 2007 – Vol. 23 – No. 08

After vasectomy reversal, motile sperm observed intraoperatively at the testicular vas, undergoing vasovasostomy, and an obstructive interval of <=8 years predict shorter time to appearance of sperm in the ejaculate.

Objective: To study the time to appearance of sperm in the ejaculate for men undergoing vasectomy reversal. Design: Retrospective chart review of men who had undergone bilateral vasovasostomy, bilateral epididymovasostomy, or a combination of vasovasostomy on 1 side and epididymovasostomy on the other. Participants/Methods: 150 men whose records included intraoperative findings with type of reversal performed, record of sperm presence or absence, and associated fluid findings from each testicular vas deferens. Results: Presence of motile sperm in vasa was associated with a shorter time to postoperative presence of sperm observed in the ejaculate: 95% of men with motile sperm in the intraoperative vasal specimen were observed to have sperm in the ejaculate by 6 months after vasectomy reversal compared to 76% of men without motile sperm in the intraoperative specimen (P =0.04). Features correlated with a shorter onset to the observation of sperm in the ejaculate within the first 3 months after vasectomy reversal included an obstructive interval of <=8 years and vasovasostomy rather than epididymovasostomy. Patient age did not affect time to the observation of sperm in the ejaculate after vasectomy reversal.

Conclusions: Motile sperm observed intraoperatively at the testicular vas, undergoing vasovasostomy, and an obstructive interval of <=8 years predict shorter time to the appearance of sperm in the ejaculate after vasectomy reversal.

Reviewer’s Comments: The similarity with previous studies by other investigators of time to sperm seen in the ejaculate, with an average of 3.2 months for vasovasostomy and 6.3 months for epididymovasostomy, provides excellent counseling information for couples considering vasectomy reversal.
