Objective:To study the ultrastructure differences of spermatozoon between normal fertile males and infertile males. Methods: Transmission electronic microscope was used to examine spermatozoon ultrastructure of subjects of which 10 were infertile males (as experimental group, EG) and 8 were fertile males (as control group, CG). The head and tail ultrastructure of spermatozoa of both groups were specially compared. Results: Multi - morphologic abnormality of ultrastructure was found in the spermatozoa of EG. The injury extent of acrosome - membrane, and the rates of mitochondria swelling and deformation were higher, and dreg of died spermatogenic cells was more in EG than those in CG. The differences were statistically significant(P 0. 05). Conclusions: There might occur close relationship between the male infertility and the injury of acrosome - membrane structure, and other abnormality of spermatozoon ultrastructure.
