[Male sterility caused by a lack of the acrosome in spermatozoa with a round shaped head].
Only properly structured spermatozoa are able for transportation and penetrating the permeable membrane of oocyte. The key role in the process of fertilization belongs to the anterior part of acrosome, i.e., the spermatozoon's head. A case of a married couple, with diagnosed 8-year-long infertility, has been presented. A spermocytogram, run in the man, revealed all spermatozoa to be with rounded heads, i.e., without acrosome. That pathology was confirmed in electron microscopy. The significance of correct examination--spermocytogram--has been stressed in the diagnostic of male infertility.
