Abstract

The aim of this study was to analyze the effects of progesterone withdrawal on gene transcription in receptive endometrium by the administration of a single dose of 50 mg of the anti-progesterone receptor mifepristone (MFP) at the time of follicle rupture (FR). Six volunteer ovulatory women were studied, taking endometrial biopsies of three control and three MFP-treated women on days LH+2 (C-LH+2) and LH+7 (T-MFP), respectively. The biopsies were prepared for RNA isolation or histological and immunohistochemistry studies. The genomic data from 14 women (C-LH+7) were included as a historical control. The functional genomic analysis of the differentially expressed genes showed that MFP interfered negatively with the bio-functions decidualization of uterus and implantation of blastocyst and embryo. The results of this study confirm but also give new information on how MFP affects endometrial gene expression when administered at the time of FR and the dose used in emergency contraception.
