Automated Seminal Fluid Examination
SQA-QWIKCheck GOLD Semen Quality Analyzer xxxxx xxxxx xx xxxxx xxxxx xxxxx xxxxx
At NDPC, we use SQA-QWIKCheck GOLD, a high performance, state of the art, a menu-driven analytical medical device for assessing Human Seminal Fluid. SQA- QWIKCheck GOLD uses a combination of electro-optics and computer algorithms to generate accurate and reproducible semen analysis results based on the WHO Laboratory Manual for the Examination and Processing of Human Semen: 6th edition (2021).
Semen analysis is the cornerstone of male fertility evaluation, with WHO guidelines providing the basis for procedural standardization and reference values worldwide. The first WHO manual was published in 1980, and five editions have been released over the last four decades. The 6th Ed. was published in July 2021. This new Edition has analyzed basic semen parameters more robustly, considering the criticisms and grey areas of the previous editions. Based on these WHO guidelines, it is now possible to evaluate semen more objectively in clinical practice using SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis.
About Various Seminal Fluid Parameters
Based on WHO Guidelines with Lower Reference Range-LRR in Bracket
Sperm Concentration (more than 16 mill/mL) Number of spermatozoa per unit volume of Semen. Total Motility(more than 42%): % of the Sperms that are moving.
Progressive Motile Sperm Concentration Total nos. of progressively moving motile cells per mL of sample. Functional Sperm Concentration: Progressive Motility (more than 30%): Spermatozoa Sperms having progressive motility & normal moving actively, either linearly or in a large circle, morphology. regardless of speed. a. Rapidly Progressive Motility in % b. Slow Progressive Motility in % Non Progressive Motility:
Average Path Velocity (more than 5 microns/sec): Time-averaged velocity of a sperm head along its average path. This path is computed by smoothing the curvilinear trajectory according to algorithms in All other patterns of motility with an absence of the instrument. progression, e.g. swimming in small circles, the Sperm Motility Index (more than 80): flagellar force hardly displacing the head, or when A quick reference parameter developed by MES. only a flagellar beat can be observed.
Anything over 80 equals a good sample.
Immotility:
Total Sperm Number (more than 39 million):
No movement.
Total nos. of spermatozoa in the entire ejaculate.
Morphology(% of Normal Forms- more than 4 %):
Semen Fructose Level:
% of Normal shape/sized sperms in the sample.
Total nos. of motile cells per mL of sample.
After about 4 hours of ejaculation: 100 mg/dL
IMPORTANT: WHO 2021 6th Guideline uses the term Lower reference limit /range instead of Biological Reference Interval. The new reference values have a clinical impact because they now classify men previously considered infertile as normal. The laboratory report should only be interpreted by a physician who can integrate other test results with the couple's assessment to determine overall status. Self-interpretation and self-medication are strongly discouraged.
