The Human Microbiome and Gender Medicine

Discoveries in molecular genetics over the last two decades have broadened our information about the genomics of complex microbial communities. As in all other fields of medicine, there is an undeniable need to explore the microbiome and the way it is impacted by biological sex. A number, although small, of recent studies have demonstrated that women and men have striking differences in the species that constitute their microbiomes. This effects pathological physiology in fields such as hepatology, oncology, autoimmune disease (most notably diabetes mellitus), autism, and obstetrics. There is still an unfortunate lack of research being done on the “microgenderome”: the interaction between microbiota, sex hormones, and the immune system. This review will highlight some of the main areas to be affected by microgenderome physiology, with an in depth focus on obstetrics.
