Surgical sperm retrieval for assisted reproduction

Area of Science:

• Reproductive Medicine
• Urology
• Andrology

Background:

• Male infertility affects a significant portion of couples seeking assisted reproduction.
• Traditional diagnostic testicular biopsy has limitations in providing viable sperm for conception.
• Intra-cytoplasmic sperm injection (ICSI) has transformed the treatment landscape for male factor infertility.

Purpose of the Study:

• To review advanced microsurgical techniques for sperm retrieval in men with non-obstructive azoospermia.
• To highlight the efficacy of combining surgical sperm retrieval with in vitro fertilization (IVF)/ICSI.
• To compare these advanced methods with traditional diagnostic testicular biopsy.

Main Methods:

• Microsurgical testicular sperm extraction (TESE) to identify spermatogenesis.
• Testicular sperm aspiration (TESA) to retrieve sperm-containing fluid or tissue.
• Sperm cryopreservation for future use.

Main Results:

• Surgical sperm retrieval techniques, combined with IVF/ICSI, are effective in achieving biological offspring for azoospermic men.
• These microsurgical approaches allow for the identification of sperm in cases previously considered untreatable.
• Sperm cryopreservation enhances treatment flexibility by decoupling sperm retrieval from ovulation timing.

Conclusions:

• Advanced microsurgical sperm retrieval techniques represent a significant therapeutic advancement for male infertility.
• These methods offer viable options for azoospermic men, surpassing the limitations of diagnostic biopsies.
• The integration of surgical sperm retrieval, IVF/ICSI, and cryopreservation provides a powerful strategy for treating severe male factor infertility.
