Brief Summary
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of childbearing age. However, the optimal infertility treatment for PCOS patients is still a matter of controversy. Despite producing more follicles and more oocytes than other women undergoing controlled ovarian hyperstimulation during an IVF cycle, women with PCOS have comparable or lower pregnancy rates. Additionally women with PCOS patients undergoing IVF have a higher risk of developing ovarian hyperstimulation syndrome (OHSS), which may be aggravated by pregnancy after an embryo transfer in a fresh cycle. Further women with PCOS are thought to have higher rates of later pregnancy complications including spontaneous abortion, pre-eclampsia, and preterm labor that may be related to impaired implantation in the superovulated endometrium. We propose a randomized clinical trial of elective embryo cryopreservation followed by a programmed cycle of endometrial preparation and frozen embryo transfer (FET) compared to fresh embryo transfer in women with PCOS undergoing in vitro fertilization (IVF).

singleton live birth rate
10 months for group A, 12 months for group B
- +3 more secondary outcomes
Study Arms (2)
fresh embryo transfer group
EXPERIMENTALrFSH/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.
frozen-thawed embryo transfer group
EXPERIMENTALrFSH/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.
Interventions
rFSH/GnRH antagonist will be administered for ovarian stimulation. Oocyte pick-up will be performed when at least two follicles ≥18mm. 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 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.
