fresh embryo transfer group
frozen-thawed embryo transfer group
rFSH/GnRH antagonist will be administered for ovarian stimulation. Two fresh embryos will be transferred at Day 3. Luteal phase support will last 2 weeks for all subjects in this group. Two weeks after embryo transfer, serum human chorionic gonadotropin (HCG) will be measured to determine pregnant or not. If biochemical pregnancy is achieved, luteal phase support will be continued to 10 weeks gestation. Pregnancy complications and final outcome will be followed up till 6 weeks after delivery.
rFSH/GnRH antagonist will be administered for ovarian stimulation. All embryos will be vitrified in fresh cycle, and at least 2 embryos should be frozen at Day 3. Two months later, two thawed Day 3 embryos will be transferred with hormone replacement therapy (HRT) prepared endometrium. Luteal phase support will last 2 weeks for all subjects in this group. Two weeks after embryo transfer, serum human chorionic gonadotropin (HCG) will be measured to determine pregnant or not. If biochemical pregnancy is achieved, luteal phase support will be continued to 10 weeks gestation. Pregnancy complications and final outcome will be followed up till 6 weeks after delivery.
