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.

Background: The question of whether patients are more likely to succeed with testicular sperm intracytoplasmic sperm injection (T-ICSI) after unsuccessful ICSI with ejaculated sperm (Ej-ICSI) remains unknown.

Objective: The study aimed to identify potential predictors of successful T-ICSI in men with idiopathic infertility and oligozoospermia (sperm concentration < 15 × 10/mL, non-azoospermic) who had previously experienced unsuccessful Ej-ICSI.

Materials And Methods: In total, 154 couples with male partners who had oligozoospermic conditions after two unsuccessful cycles of Ej-ICSI switched to T-ICSI.

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.
