Abstract
The straight line velocity of 500 individual spermatozoa was measured immediately before their direct injection into the cytoplasm of 500 me taphase II oocytes, The straight line velocity (VSL) did not have a no rmal distribution (P < 0.01) and ranged between 0 and 35 mu m/s. The f ertilization rate (84%) was significantly (P < 0.008) higher in the qu artile of the sperm population with the highest VSL compared to the fe rtilization rate (68 %) in the quartile with the lowest VSL, Embryo cl eavage and embryo quality were not different in the quartiles of the s perm population used for injection.
