Performance evaluation of sperm concentration, motility, and morphological analysis for GSA‐810 series of sperm quality analysis system
2023
Overview
Background The performance evaluation of each computer‐assisted sperm analysis (CASA) system may provide a basis for the interpretation of clinical results and further improvement of the CASA system. Methods The accuracy of the GSA‐810 CASA system was evaluated by detecting latex bead quality control products. The precision of sperm concentration, morphology, and percentages of progressively motile sperm (PR) were evaluated by coefficient of variation (CV). Three samples with sperm concentration of about 100 × 106/mL were diluted to evaluate the linear range. Results The detection values of latex beads were within the range of target values. The CVs of sperm concentration and PR were significantly and negatively correlated with sperm concentration (r = −0.561, p = 0.001) and PR value (r = −0.621, p < 0.001), respectively. The R2 values of the linear range of sperm concentration were ≥0.99. There was no significant difference in sperm motility and PR within 1–10 min at 36.5°C ± 0.5°C. The coincidence rates of sperm morphology and sperm head morphology for 36 semen samples analyzed by the GSA‐810 system and manual method were 99.40% and 99.67%, respectively. The CVs of the percentage of sperm with abnormal morphology and percentage of sperm with abnormal head morphology were less than 5%. Conclusion The GSA‐810 system can accurately analyze normal semen samples, but the repeatability of the results is poor for oligozoospermia and asthenozoospermia samples. The future CASA system for analyzing sperm morphology should focus on recognizing the middle and tail segments of a spermatozoon. The GSA‐810 system can accurately detect sperm concentration in semen samples with sperm concentrations in the range of (2–100) × 106/mL. Semen samples with a sperm concentration between 50 × 106/mL and 100 × 106/mL can be directly detected using the GSA‐810 system without dilution. The higher the sperm concentration and PR, the better the repeatability of the detection results.
