Article Synopsis
- 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.

Article Synopsis
- The study investigates global practices and challenges in using sperm DNA fragmentation (SDF) assays, which can affect male reproductive potential, as outlined in the latest WHO manual.
- A survey of 436 reproductive clinicians revealed that the most popular SDF assay is TUNEL, with a significant influence from availability on their choices.
- Clinicians see the value of SDF testing in understanding infertility but face barriers like insufficient professional guidelines and a lack of accepted reference values for interpreting SDF results.
Article Synopsis
- The meta-analysis investigates the effects of varicocele repair on semen parameters in infertile males, combining data from diverse studies without language restrictions.
- A total of 351 studies were analyzed, revealing significant improvements in several semen parameters post-repair, including semen volume, sperm concentration, total sperm count, motility, and morphology, while sperm vitality showed no improvement.
- This research is the largest of its kind and highlights the benefits of varicocele repair for male infertility, contributing valuable insights for clinical practice.

Article Synopsis
- The study investigates global practices for managing sperm DNA fragmentation (SDF) in infertile men, highlighting its impact on fertility and assisted reproductive technology (ART).
- A survey collecting data from 436 reproductive experts across 55 countries revealed a common recommendation for lifestyle changes and antioxidants, with varying durations for treatment and differing management approaches for specific infertility cases.
- The findings indicate a lack of uniformity in practices, emphasizing the need for standardized guidelines and expert consensus for treating men with elevated SDF.
