Nonobstructive azoospermia (NOA) affects about 60% of men with azoospermia, representing a severe form of male infertility. The current approach to manage NOA primarily involves testicular sperm retrieval methods such as conventional testicular sperm extraction (c-TESE) and microdissection testicular sperm extraction (micro-TESE). While combining testicular sperm retrieval with intracytoplasmic sperm injection (ICSI) offers hope for patients, the overall sperm retrieval rate (SRR) stands at around 50%.

- Non-obstructive azoospermia (NOA) is a prevalent and complex issue with varied treatment options and no definitive guidelines, leading to differing management practices internationally.
- A comprehensive survey with 336 responses from specialists in 49 countries explored current medical and surgical strategies for NOA, analyzing results against existing guidelines and offering expert recommendations.
- Key findings included diverse approaches to hormonal therapy, significant variation in sperm retrieval success rates, and differing protocols around varicocele repair and follicle-stimulating hormone cutoff levels for sperm retrieval.
Article Synopsis
- * Conducted from July to September 2022, a questionnaire gathered responses from 367 doctors in 49 countries, focusing on how they diagnose NOA through methods like hormone tests and genetic analyses.
- * The survey identified that while many practices align with guidelines, significant differences in approaches were found, underscoring the need for standardized, evidence-based international guidelines for NOA evaluation.
