L Dubin, R D Amelar

    Urology
    |November 1, 1977
    PubMed
    Summary

    Surgical varicocele repair improved semen quality in 70% of subfertile men, leading to a 53% pregnancy rate. Postoperative human chorionic gonadotropin therapy further enhanced outcomes for men with lower sperm counts.

    Area of Science:

    • Urology
    • Reproductive Medicine
    • Andrology

    Background:

    • Varicocele is a common cause of male infertility.
    • Surgical correction aims to improve semen parameters and fertility outcomes.
    • Predictors of successful surgical outcomes require further investigation.

    Purpose of the Study:

    • To evaluate the efficacy of varicocele surgery in improving semen quality and pregnancy rates.
    • To assess the impact of preoperative sperm count on surgical outcomes.
    • To determine the benefit of adjuvant human chorionic gonadotropin (hCG) therapy in specific patient subgroups.

    Main Methods:

    • A retrospective analysis of 986 subfertile men undergoing varicocele repair over twelve years.
    • Follow-up for at least two years post-surgery.
    • Comparison of outcomes based on preoperative sperm counts (<10 million/mL vs. >10 million/mL) and use of postoperative hCG.

    Main Results:

    • Overall, 70% showed improved semen quality and 53% achieved pregnancy.
    • Patients with preoperative sperm counts >10 million/mL had higher improvement rates (85%) and pregnancy rates (70%).
    • Postoperative hCG therapy in patients with <10 million/mL sperm count significantly improved outcomes (55% improved, 45% pregnancy rate).

    Conclusions:

    • Varicocele surgery is an effective treatment for subfertile men, significantly improving semen quality and pregnancy rates.
    • Preoperative sperm count is a key prognostic factor for surgical success.
    • Adjuvant hCG therapy can enhance fertility outcomes in men with lower preoperative sperm counts after varicocele repair.
