    Vasovasostomy surgery for male infertility resulted in a 43% pregnancy rate. Post-surgery semen analysis showed good sperm counts but reduced motility and viability, prompting further investigation into potential causes.

    Area of Science:

    • Urology
    • Reproductive Medicine
    • Andrology

    Background:

    • Vasovasostomy is a surgical procedure for male infertility reversal.
    • Assessing the efficacy of vasovasostomy is crucial for reproductive health outcomes.

    Purpose of the Study:

    • To evaluate the pregnancy success rate following bilateral vasovasostomy.
    • To analyze semen parameters, including sperm count, motility, and viability, post-vasovasostomy.

    Main Methods:

    • Retrospective analysis of 205 men undergoing bilateral vasovasostomy over an 8-year, 4-month period.
    • Follow-up included assessment of pregnancy status and semen analysis.

    Main Results:

    • A 43% pregnancy rate was achieved in patients with available follow-up data.

  • Semen analyses generally indicated good sperm counts but reduced sperm motility and viability.

    • Conclusions:

    • Vasovasostomy can lead to successful pregnancies, though post-operative sperm quality may be compromised.
    • Further research is needed to determine if abnormal epididymal function or antisperm antibodies contribute to reduced sperm motility and viability.
