The reliability and validity of semen analysis depend solely on the expertise and skills of laboratory personnel.5 Hence, frequent training and continuous education and future practitioners in the field of andrology are of great importance to ensure the precision and accuracy of the test results.6 Due to the complexity of the test, and it being done manually on several steps, strict adherence to the semen laboratory manual must be followed to ensure correct results. Laboratory personnel are responsible to ensure the quality of services provided. This is achieved through the establishment of quality control (QC) and quality assurance (QA) plans, which are fundamental to monitor the process rigorously.7
Objectives: In this review, we described the standardized laboratory procedures essential for proper evaluation of semen quality, and the established QC and QA plans in the context of managing the quality of a busy clinical andrology laboratory (see figure below). Additionally, we described several clinical scenarios in which reliable semen analysis results have played a significant role in the management of infertile males.
Recommendations: Understanding the principles and procedures for the analysis of semen plays a major role in clinical practice and the management of infertile patients. In this context, it is essential to enforce strict QC in the andrology laboratories to ensure reproducible results of semen analysis. Participation in proficiency testing for reproductive laboratories engaged in moderate or high complexity testing is necessary by all accrediting agencies. Finally, understanding the reference ranges for normal semen parameters and definitions of various categories of abnormal semen parameters is important in the clinical interpretation of laboratory results.
