简要总结

The study is designed as a proof of concept pilot study with 3 study arms to evaluate the safety and feasibility of the use of oral probiotics and/or antibiotics in women with unexplained infertility/endometriosis. Our secondary outcomes will assess In Vitro Fertilization outcomes, and changes in the uterine microbiota (bacteria), intestinal barrier integrity, and urinary metabolites in response to study interventions.

详细描述

Previous research has demonstrated that the uterine microbiota can impact fertility and embryo implantation. This information leads to the hypothesis that prophylactic antibiotic and/or probiotic treatment may improve reproductive outcomes in women with unexplained infertility/endometriosis who are seeking In Vitro Fertilization (IVF). No therapeutic protocols to improve these outcomes currently exist. However, there are safe and easily accessible medications and supplements that may be able to optimally modify the uterine microbiota. Herein we are proposing a proof of concept pilot study of the feasibility, safety and tolerability of administering oral probiotics, or oral probiotics in combination with antibiotics, to women seeking IVF.
