    Vasovasostomy surgery achieved a 92% patency rate, with 45% of eligible patients achieving pregnancy. Postoperative sperm motility, not sperm count, significantly correlated with pregnancy success.

    Area of Science:

    • Urology
    • Reproductive Medicine
    • Surgical Outcomes

    Background:

    • Vasovasostomy is a surgical procedure for male infertility reversal.
    • Assessing the long-term efficacy of vasovasostomy is crucial for patient counseling.
    • Evaluating factors influencing successful outcomes is essential for reproductive health.

    Purpose of the Study:

    • To evaluate the surgical patency and functional success rates of vasovasostomy.
    • To identify correlations between semen parameters and pregnancy rates after vasovasostomy.

    Main Methods:

    • Retrospective analysis of 96 males undergoing vasovasostomy between 1976-1978.
    • Semen analysis to determine sperm presence (patency rate).
    • Pregnancy initiation by partners to determine functional success rate.

    Main Results:

    • Surgical patency rate was 92% (76 of 83 patients with semen analysis).
    • Functional success rate was 45% (32 of 71 eligible patients initiated pregnancy).
    • Significant correlation found between postoperative sperm motility and pregnancy rate.

    Conclusions:

    • Vasovasostomy demonstrates high surgical patency.
    • Postoperative sperm motility is a key predictor of successful pregnancy following vasovasostomy.
    • Sperm count alone was not significantly correlated with pregnancy rates.
