Abstract

Background: A complex of effector and predominant regulatory immune responses are induced in the female reproductive tract (FRT) due to insemination that is necessary to achieve pregnancy. The expression of immune regulatory molecules by spermatozoa indicates the significance of the interaction between spermatozoa and immune cells recruited to the FRT in the preparation of appropriate immunity for pregnancy occurrence. One of the immune regulatory molecules is CD5 whose expression by spermatozoa has not yet been investigated. Therefore, the aim of this study is to investigate the expression of CD5 on the surface of human spermatozoa. Semen samples were collected from 30 healthy men with normal semen status. CD5 expression on purified spermatozoa was evaluated by flow cytometry methods. Results: The results showed the mean ± SD percentage of CD5 positive spermatozoa was 49.41 ± 8.73. Conclusion: CD5 is expressed on spermatozoa. © 2022, The Author(s).
