Area of Science:

  • Andrology
  • Reproductive Medicine
  • Laboratory Science

Background:

  • Accurate evaluation of strict sperm morphology is crucial for male fertility assessment.
  • Standardization and quality control are essential for reliable andrology laboratory results.

Purpose of the Study:

  • To develop and evaluate a training program incorporating continuous quality control for strict sperm morphology assessment.
  • To assess the feasibility of national and international implementation of such a program.

Main Methods:

  • A prospective analytical study involving nine Swiss andrology laboratories.
  • Participants underwent a training course followed by 9 months of continuous quality control with Papanicolaou-stained sperm slides.
  • A reference laboratory provided standardized slides and analyzed results every 3 months.

Main Results:

  • Technician proficiency, measured by the percentage of normal spermatozoa, showed a difference of less than 10% from the reference laboratory in 94% of cases.
  • Statistical analysis (P>.2) indicated no significant differences between the reference laboratory and participating laboratories for most slides evaluated.

Conclusions:

  • Training and proficiency testing for strict sperm morphology can be effectively conducted at national and international levels with reference laboratory support.
  • Mandatory global quality control measurements in andrology laboratories are recommended to ensure consistent and successful technician performance.
