Microbiome and Endometrial Receptivity in Obese Infertile Women

The objective of this project is the identification and quantification of the main bacterial communities present in the endometrial microbiota in obese infertile patients, to assess if there is an alteration of their composition dependent on the body mass index, and if such alteration it could influence the reduction of endometrial receptivity, demonstrated in obese women. If obese patients have an altered digestive microbiota and, at the same time, a lower endometrial receptivity, the investigator want to assess whether such reduction in receptivity may depend on an alteration in the endometrial microbiota, which in non-obese infertile patients has been shown to negatively influence the reproductive results
