To study the relations between male infertility and centrosome protein (centrin) and the functions of centrin in spermatogenesis, the matured spermatozoa of 10 normal male people and 18 male infertility patients were stained by immunofluorescence labeling antibody against centrin. The results showed that two fluorescence signal dots appeared in the normal male spermatozoa and were located at the base of flagellum. They are proximal centriole and distal centriole. However, in some spermatozoa of the male infertility, centrin protein was located abnormally at the base of flagellum and its staining signals were spread, the normal proximal and distal centrioles were confused and could not be recognized separately. These results suggest that abnormality of centrosome protein may be related to male infertility. This discovery may be used as a marker of abnormal sperm and male infertility.
