In the Paper article, the collection of the studies related to the effect of ovarian stimulation on endometrium of uterus and implantation have been investigated. History: Monash group used ovarian stimulation method for the first time in infertility treatment and also, they could increase the pregnancy rate using this method. However, the percentage of successful embryonic implantation has been decreased by this method due to imbalance of hormones and the effect of these hormonal changes on endometrium. Materials and Methods: Studies done by researchers have shown that ovarian stimulation causes undesirable changes in endometrium which in turn such alterations lead to inadequate attachment of embryo to endometrium and finally decrease the percentage of embryonic implantation. Conclusion: Based on several researches and the importance of using the ovarian stimulation method in treatment of infertility, also due to undesirable effects that ovarian stimulation has on endometrium during embryonic implantation it is inevitable that more investigations should be done for improvement of treatment methods in infertility clinics.
