title: [Round cells of human sperm].
abstract: Many round cells are found whose number may become conspicuous. These cells may originate as well from germinal as from somatic lines. Electron microscopy is the only way to distinguish the two kinds of origin. In some specimens germinal cells predominate (spermattids, plurinuclear cells), in others there are many phagocytic cells which may ingest a great number of spermatozoa and this phenomeon may stimulate an azoospermy by failure of spermatogenesis. The study of human sperm (or testicular biopsies) by electron microscopy is needed to obtain the necessary information in order to orient diagnosis, prognosis and therapy.
