The WHO laboratory manual for the examination and processing of human semen (Sixth Edition) is a definitive global reference published by the World Health Organization to standardize procedures for assessing male reproductive health. Since its initial publication in 1980, it has served as the recognized standard for clinical and research laboratories worldwide, aiming to ensure the quality, reliability, and comparability of semen analysis results.
The manual is structured into several comprehensive sections:
• Basic Examination: Covers essential procedures such as macroscopic evaluation, sperm concentration, motility, and morphology.
• Extended and Advanced Examinations: Provides detailed protocols for specialized tests, including sperm DNA fragmentation, oxidative stress testing, and computer-aided sperm analysis (CASA).
• Sperm Processing: Detailed techniques for preparing spermatozoa for assisted reproductive technologies (ART) and cryopreservation protocols.
• Quality Management: Emphasizes rigorous quality assurance and quality control to minimize errors and maintain laboratory standards.
Ultimately, the manual supports international efforts toward universal access to sexual and reproductive health care by providing evidence-based tools for diagnosing male infertility and monitoring treatments. It serves as an essential resource for technologists, scientists, and clinicians dedicated to improving male reproductive outcomes.
