title: Structure of the plasmalemma of human spermatozoa after treatment with antispermatozoa serum and concanavalin A.
abstract: Human ejaculated spermatozoa were treated with antispermatozoa serum as well as with the same serum and concanavalin. A. At both experimental conditions clusters of intramembranous particles both on P-face and on E-face in the acrosomal and postacrosomal regions were seen. The clusters were with different form and size and were built up from different number of intramembranous particles. Large areas with single particles or in some cases devoid of these particles were found out.
