Assessing the Endometrial Environment in Recurrent Pregnancy Loss and Unexplained Infertility

The purpose of this study is to determine if patients with recurrent pregnancy loss or unexplained infertility have an altered uterine gene expression or uterine microbiome (micro-organism composition) during the window of embryo implantation. Furthermore we would like to assess for women with an abnormal uterine gene expression whether vaginal progesterone medication improves or alters gene expression and for women with an abnormal microbiome whether antibiotic treatment followed by probiotic treatment normalizes the microbiome.

Stanford is currently not accepting patients for this trial.
