Abstract:Mice of the ICR strain were orally administered with Sophoricoside (SOPH) to investigate the anti-fertility effect on female mice. The pregnant mice received SOPH at concentrations of 0 mg/kg·day, 150 mg/kg·day, 300 mg/kg·day and 600 mg/kg·day from day 1 (D1) of gestation to sacrifice, and the effects of the treatment on fertility were evaluated. Administration of SOPH led to blocked formation of pinopodes, compromised endometrial receptivity (D5) and decreased number of embryo implantation sites (P<0.01). The protein expression (D4, D5 and D6) level of ERα was down-regulated (P<0.05) by SOPH in the mouse endometrium, while the PR was up-regulated (P<0.01). This study suggested that sophoricoside can cause the failure of embryo implantation by modulating the expression levels of ERα and PR in uterus, affecting the formation of pinopodes and reducing mice endometrial receptivity.
