WebSep 28, 2024 · The evaluation of sperm motility and morphology mainly depends on the seminologist's experience. Adding the evaluation of speed would re-introduce an information that is certainly less precise, increasing variability, possibility of error and, thus, reducing standardization among laboratories. WebNov 1, 2013 · Regarding sperm velocity, the characteristics of the three sperm subpopulations were as follows: slow and nonlinear (SP1 vel), fast and linear (SP2 vel), and fast and nonlinear (SP3 vel). Subpopulations based on sperm velocity were classified as slow or fast based on whether their VCL was below or above average (average VCL, 136.7 …
