Summary
Implementing a structured training program and continuous quality control significantly reduced inter-laboratory variability in sperm morphology assessments. This approach enhances the reliability of andrology laboratory results.
Area of Science:
- Reproductive Medicine
- Andrology
- Laboratory Quality Control
Background:
- Inter-technician and inter-laboratory variability in sperm morphology evaluation is a significant concern.
- Standardized and accurate semen analysis is crucial for male fertility assessments.
Purpose of the Study:
- To develop and evaluate an intensive training program with continuous quality control for sperm morphology assessment.
- To reduce variability in sperm morphology evaluations across different laboratories.
Main Methods:
- Twenty andrology laboratories in sub-Saharan Africa participated in a World Health Organization (WHO) semenology workshop.
- Intensive training in strict sperm morphology evaluation was followed by quarterly quality control assessments.
- Sperm morphology results were compared against a reference laboratory.
Main Results:
- The mean percentage difference between participants and the reference laboratory decreased from 33.5% at baseline to 14.3% at 3 months and 5.0% at 6 months post-training.
- Pre-training differences were statistically significant compared to 3-month and 6-month post-training differences (P = 0.0002 and P = 0.007, respectively).
- No significant difference was observed between 3-month and 6-month results (P = 0.27), indicating sustained improvement.
Conclusions:
- Intensive training and continuous quality control are effective in improving sperm morphology assessment accuracy.
- National and international training and proficiency testing programs are feasible with reference laboratory support.
- Mandatory global quality control in andrology laboratories is recommended to ensure consistent and reliable results.
