(A) Development of headless spermatozoa. Only the proximal centriole contacts the basal plate of the nucleus of the spermatid. The distal centriole is separated and develops the headless flagellum. Drawing on the basis of electron micrographs. From Ref. [9]. (B) Loss of the mitochondrial sheath during spermiogenesis. The spermatozoon is immotile. Drawing on the basis of electron micrographs. From Ref. [9]. (C) Development of malformed fagellar structures. Drawing on the basis of electron micrographs. From Ref. [9]. (D) Multiple malformations of spermatids. Drawings on the basis of electron micrographs from testicular specimen of several patients aged 43–85 years. The testes were removed by surgery as an additive treatment of prostatic cancer.
