Experimental

Arm Label

fresh embryo transfer group

frozen-thawed embryo transfer group

Arm Description

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.

Outcomes

Primary Outcome Measures

live birth rate
This will be based on the outcome of either the fresh embryo transfer after ovarian stimulation (Group A) or the outcome of the first frozen embryo transfer cycle (Group B) as will all other secondary outcomes.

Secondary Outcome Measures

Ovarian hyperstimulation syndrome (OHSS) incidence
clinical pregnancy rate
This will be based on the visualization of a intrauterine gestational sac by ultrasound.
Pregnancy Loss rate
Loss of pregnancy will be defined by any positive pregnancy test that does not result in a live birth and will be tracked.
ectopic pregnancy rate
singleton live birth rate
pregnancy complication rate
Complications of pregnancy including gestational hypertension, diabetes, preterm labor, disorders of placentation will be collected in all patients with ongoing clinical pregnancies.
Congenital Anomalies rate
We will collect all recognized fetal and infant anomalies that occur within the trial.
neonatal complication rate
We will collect complications that occur in the neonate including admission to the neonatal intensive care unit (NICU), hospitalization, etc.

5. Study Description

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).
Detailed Description
This will be a multi-center, prospective, randomized (1:1 ratio)clinical trial of frozen-thawed embryo transfer vs. fresh embryo transfer after a uniform gonadotropin-releasing hormone (GnRH) antagonist protocol in infertile PCOS patients receiving IVF therapy. Qualified 1180 patients are randomized into either of two groups: group A will undergo fresh embryo transfer (590 cases), Group B will undergo elective cryopreservation of all embryos followed by transfer of thawed embryos to a programmed endometrium (590 cases). All of the participants will receive recombinant follicule stimulating hormone (rFSH)/GnRH antagonist protocol for ovarian stimulation and standardized luteal phase support. The target population will be infertile PCOS patients aged between 20 and 35 years, diagnosed by the Chinese PCOS Criteria(i.e. menstrual disorders PLUS either one of the remaining two criteria, hyperandrogenism or polycystic ovaries on ultrasound, with exclusion of secondary causes of hyperandrogenism and ovulation dysfunction). And subjects will be those who are undergoing their first IVF or intracytoplasmatic sperm injection (ICSI) cycle without other known factors interfere reproductive or metabolic functions. The randomization will take place at the oocyte pick-up day by an on-line randomization system. The pregnancy test results, pregnancy complications, congenital anomalies neonatal complications will be followed up by checking medical records and telephone calls.
