Abstract

Objective: The appropriate interaction between a BLASTOCYST and the endometrium is essential for successful implantation. Numerous factors, including hormone receptors (progesterone receptor), cytokines [leukemia inhibitory factors (LIF)], and adherence molecules such as E-CADHERIN are involved in the cross-talk that occurs between the embryo and endometrium. Studies show that a lack of these genes impact endometrial receptivity. In this study, we compare the expression levels of E-CADHERIN, LIF, and PROGESTERONE RECEPTOR (PgR) genes in BLASTOCYSTs that have been obtained from super ovulated mice to those obtained from natural cycles.Materials and Methods: In this experimental study, for the experimental group, a total of 17 virgin female NMRI mice (6-8 weeks old) were injected with 7.5 IU pregnant mare serum gonadotropin (PMSG). Their BLASTOCYSTs (approximately n=120) were flushed out after 3.5 days, following administration of human chorionic gonadotropin (hCG). The control group consisted of BLASTOCYSTs from 62 female mice that were mated with male mice. The natural cycle BLASTOCYSTs were flushed out from the female mice uteri 3.5 days after mating. The expression levels of E-CADHERIN, LIF, t PgR genes were examined by quantitative real-time reverse-transcriptase polymerase chain reaction (RT-PCR). Data were analyzed by the student’s t-test (one sample t-test).Results: Expression levels of all studied genes were significantly lower in the hormone-treated group compared to the natural cycle BLASTOCYSTs (p<0.05).Conclusion: Although OVARIAN STIMULATION is utilized to obtain more oocytes in ART cycles, it seems that this could disadvantageous to implantation because of the decrease in expression levels of certain genes. Because of the important roles of E-CADHERIN, LIF, and PROGESTERONE RECEPTOR in the implantation process, we have shown lower expression levels of these genes in mouse BLASTOCYSTs obtained from ovarian-stimulated mice than those derived from the natural cycle. The results observed in this study have shown the possibility of an unfavorable effect on implantation and pregnancy rate.
