A total of 130 semen samples were examined for motility (by computer-assisted sperm analysis), morphology and acrosomal status. A high positive correlation was found between percentages of normal forms and progressive motility in the whole semen (r = 0.539, P < 0. 0001) as well as in the Percoll fraction (r = 0.702, P < 0.0001). Among the specific abnormalities, acrosome defects were most highl...
