Continuous quality control and refresher training significantly improve sperm morphology assessment accuracy. This enhances the reliability of semen analyses for fertility evaluations.

Area of Science:

  • Andrology
  • Reproductive Medicine
  • Quality Control in Diagnostics

Background:

  • Sperm morphology assessment is crucial for predicting fertilization success but suffers from inter-observer variability.
  • Subjective evaluation by laboratory technicians impacts the reliability of semen analysis reports.

Purpose of the Study:

  • To evaluate the impact of continuous external quality control and refresher training on sperm morphology reading skills.
  • To determine the effectiveness of monitoring and retraining over 40 months.

Main Methods:

  • Nineteen technicians from 12 laboratories participated in a quality control program with initial training.
  • Quarterly monitoring and annual refresher courses were implemented for a subset of participants.
  • Technician performance was assessed against a reference laboratory using +/- 0.5 SD and +/- 0.2 SD error limits.

Main Results:

  • 78% of technicians maintained readings within +/- 0.5 SD limits after initial training and ongoing monitoring.
  • Technicians attending annual refresher courses consistently achieved results within +/- 0.2 SD limits.
  • Initial training combined with continuous quality control and refresher courses demonstrated sustained high-level performance.

Conclusions:

  • Initial training and ongoing external quality control are essential for accurate sperm morphology assessment.
  • Annual refresher courses further enhance and maintain high proficiency in morphology readings.
  • Standardized training and quality assurance programs are vital for reliable andrology laboratory results.
