dc.description.abstractThis study compared the automatic sperm classification generated by computer-assisted semen analysis (CASA) with a multivariate clustering approach (k-means). Both methods identified 3 sperm subpopulations with distinct motility profiles. However, the k-means clustering method provided clearer group definitions and reduced overlap between subpopulations, suggesting that multivariate methods offer a more detailed characterization of sperm heterogeneity than the automatic CASA classification.
