A new procedure for determining acrosomal status of very small numbers of human sperm.
The acrosome of human sperm cannot be easily distinguished by light microscopy. Although several techniques are now available to label the acrosomal region of human sperm and report acrosomal status, they generally require large numbers of sperm. We describe here a new procedure in which sperm are collected and treated on small-pore filters. The acrosomal region is then labeled using fluoresceinated lectin. The main advantage of this method is that it enables the study of the acrosomal status of sperm in samples with very low sperm concentration.
