[Animal models of male genital tract chlamydia infection: An update].

Chlamydia trachomatis infection is one of the most prevalent sexually transmitted diseases in males and studies on its pathogenic and immunologic mechanisms are rather limited. Animal models play an important role in studying the pathogenesis, course and treatment of human diseases, and those of male genital tract chlamydial infection are relatively few and not well developed. This article focuses on the chlamydia species, animal species, infection route, infected organ, and infection process of chlamydia, as well as its impact on reproduction, aiming to provide some help for further studies of male genital tract chlamydial infection.
