    Summary

    Surgical sperm retrieval techniques like TESE, PESA, and MESA successfully obtained sperm in 76% of men with azoospermia. These methods offer hope for correcting male infertility and achieving pregnancy.

    Area of Science:

    • Reproductive Medicine
    • Andrology
    • Urology

    Background:

    • Azoospermia, the absence of sperm in ejaculate, is a significant cause of male infertility.
    • Assisted reproductive technologies (ART) are crucial for managing severe male infertility.
    • Surgical sperm retrieval offers a solution for azoospermic individuals seeking biological fatherhood.

    Purpose of the Study:

    • To evaluate the efficacy of surgical sperm retrieval techniques in azoospermic patients.
    • To assess the subsequent fertilization and pregnancy rates following intracytoplasmic sperm injection (ICSI).

    Main Methods:

    • Retrospective analysis of 42 infertile couples where husbands had azoospermia.
    • Performed 53 surgical interventions: Testicular Sperm Extraction (TESE), Percutaneous Epididymal Sperm Aspiration (PESA), and Microsurgical Epididymal Sperm Aspiration (MESA).

  • Spermatozoa obtained were used for Intracytoplasmic Sperm Injection (ICSI).

    • Main Results:

    • Spermatozoa were successfully retrieved from 32 (76.1%) of the 42 patients.
    • Fertilization occurred in 21 (50%) of the ICSI cycles.
    • Clinical pregnancies were achieved in 10 (23.8%) of the couples.

    Conclusions:

    • Surgical sperm retrieval techniques (TESE, PESA, MESA) are effective in obtaining spermatozoa in a majority of azoospermic men.
    • These procedures significantly expand treatment options for male infertility.
    • ART combined with surgical sperm retrieval improves pregnancy outcomes for infertile couples.
