title: [Ultrastructural cytochemistry of human spermatozoa].
abstract: Enzymatic activities and repartition of glycoproteins were studied with electron microscopy in human ejaculated spermatozoa. Enzymatic activities are localised in the head of spermatozoon: arylsulfatase in the acrosome, acid phosphatase in the periacrosomal cytoplasm. Phosphotungstic acid at low pH and colloïdal iron allow detection of glycoproteins and acid groups on the sperm cell surface. Glycoproteins are present in the acrosome. These results are slightly different to those obtained in other species.
