Infectious Disease and Reproductive Health A Review

Human reproduction provides unique opportunities for the transmission of infectious agents. Furthermore, the mother and her offspring have distinct susceptibilities to infection at each stage of reproduction, from conception and gestation to parturition and the neonatal period. The impact of pathogens on reproduction can be mitigated or exacerbated depending on timing of acquisition during pregnancy. Similarly, factors such as maternal immune response, nutritional status, or concurrent infection may modify the effect of an infectious agent. In this review, we discuss the evidence-or lack thereof-for associations between infectious agents and reproductive problems at each stage of reproduction. We focus on well-substantiated associations, and consider several emerging or controversial associations. We discuss the challenges, limitations, and opportunities related to epidemiologic research on infectious disease and reproductive outcomes.
