They were divided into three groups according to different kinds of endometrial preparation methods, natural cycle group(n= 89), induced ovulation cycle group(n = 110), and hormone replacement therapy (HRT) cycle group(n = 124). Exclusion criteria in this study included concurrent of hydrosalpinx, endometriosis and adenomyosis, endometrial polyps and poor ovarian reserve. The study protocol was approved by the Ethical Review Board of Investigation in Human Being of Shenzhen Hospital of Peking University.\nResults\nThere had no significant differences in three groups among age,duration of infertility, body mass index,intima-medial thickness on transfer day, and the number and quality of transfer embryo (P>0.05). There had no significant differences in three groups among clinical pregnancy rates, spontaneous abortion rates, implantation rates, ectopic pregnancy rates and multiple pregnancy rates(P> 0.05). Rate of cycle cancellation (with embryo factor excluded) in natural cycle group was much higher than that in induced ovulation cycle group and HRT cycle group, respectively (P<0.05).\nConclusions\nDuring FET cycle, three kinds of endometial preparation methods have their advantages and disadvantages. Therefore, further studies are needed to select the personalized endometrial preparation under individual conditions.\n| 1 |\nPinborg A. To transfer fresh or thawed embryos? [J].
