[Azoospermia: ICSI with synchronous versus non asynchronous testicular sperm retrieval]

Area of Science:

• Reproductive endocrinology and infertility.
• Urology and andrology.

Context:

• Management of infertile couples facing azoospermia.
• Challenges in predicting sperm presence in non-obstructive azoospermia.

Purpose:

• To review advancements in azoospermia management using intracytoplasmic sperm injection (ICSI).
• To discuss diagnostic challenges in non-obstructive azoospermia.
• To recommend optimal diagnostic and therapeutic strategies.

Summary:

• Intracytoplasmic sperm injection (ICSI) has significantly improved outcomes for infertile men with obstructive and non-obstructive azoospermia.
• Predicting sperm availability in non-obstructive azoospermia is difficult based on clinical and complementary investigations alone.
• Testicular biopsy remains the definitive diagnostic test for sperm detection in non-obstructive azoospermia.

Impact:

• Highlights the critical role of testicular biopsy in diagnosing non-obstructive azoospermia.
• Recommends non-synchronic testicular biopsy with concurrent sperm cryopreservation to enhance treatment efficiency.
• Aims to prevent unnecessary ovarian hyperstimulation by optimizing the timing of sperm retrieval and fertilization procedures.
