Impact of Estrogen and Progesterone on Immune Cells and Host–Pathogen Interactions in the Lower Female Reproductive Tract

Microbial infections are a threat to women’s reproductive health. Although reproductive cycles and pregnancy are controlled by sex hormones, the impact of hormones on host–pathogen interactions and immune function in the female reproductive tract are understudied.

Zusammenfassung:Microbial infections are a threat to women’s reproductive health. Although reproductive cycles and pregnancy are controlled by sex hormones, the impact of hormones on host–pathogen interactions and immune function in the female reproductive tract are understudied. Furthermore, the changing endocrine environment throughout pregnancy may influence how and when women are susceptible to ascending infection. Because most intrauterine microbial infections originate in the lower reproductive tract, it is vital that future studies determine how different hormonal conditions influence the lower reproductive tract’s susceptibility to infection to understand temporal components of infection susceptibilities across pregnancy. These studies should also extend to nonpregnant women, as it is critical to establish how hormonal fluctuations across the menstrual cycle and hormonal contraceptives may influence disease susceptibility. This review summarizes current knowledge of how estrogen and progesterone impact vaginal and cervical mucosal immunity, barrier function, and interactions with microbial communities.
