Clinical Trial Summary

A single center, prospective, open-label, non-inferiority randomized controlled clinical trials (1:1 treatment ratio) regarding pregnancy outcomes between IVM and standard IVF among infertility couples with PCOS in China.

Description:

A single center, randomized controlled clinical trial will enroll 350 couples with PCOS undergoing their first cycle of IVF. The participation in this study will be approximately 2 years with a total of 7 visits from the cycle beginning, pregnancy to delivery. On day 2 or day 3 following the onset of menstrual bleeding, eligible patients will be allocated to two groups at a ratio of 1:1- IVM protocol, and standard IVF protocol. All participants will be randomized through stratified block randomization according to the study sites.

Intervention

Procedure:
• standard IVF
Ovarian stimulation will be performed by a standard protocol using gonadotrophin-releasing hormone antagonist (GnRH-ant) in association with recombinant FSH (rFSH) and human chorionic gonadotrophin (hCG).Oocyte retrieval is scheduled for 36 (±2) after hCG injection.The retrieved cumulus oocyte complexes (COC) will be inseminated using ICSI or conventional IVF according to the seman analysis. All embryos will be cultured to blastocyst stage and be vitrified.

Drug:
• In vitro maturation
Controlled ovarian stimulation protocol will not performed in this group patients. Transvaginal ultrasound scanning was examined on natural cycle to monitor the follicle size in group B participants. Oocyte retrieval was scheduled once the endometrium had reached at least 6 mm in thickness and there was no follicle larger than 10 mm. After oocyte retrieval, the COCs will be cultured for 28-32h in special IVM media in order to get the matured oocytes. All the metaphase II (MII) oocytes were inseminated by means of intracytoplasmic sperm injection (ICSI). All embryos will be cultured to blastocyst stage and be vitrified.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	the proportion of ongoing pregnancy leading to live birth	number of ongoing pregnancy leading to live birth resulting from the first oocyte retrieval cycle after the randomization ( 6 month) divided by the number of patients with oocyte retrieval	after 22 weeks of gestation
Secondary	implantation	Number of gestational sacs observed per embryo transferred	28 days after embryo transfer
Secondary	clinical pregnancy	one or more observed gestational sac or definitive clinical signs of pregnancy under ultrasonography at 7 weeks after embryo transfer (including clinical documented ectopic pregnancy)	7 weeks after embryo transfer
Secondary	Miscarriage	Spontaneous loss of an intra-uterine pregnancy prior to 28 completed weeks of gestational age	28 weeks of gestation
Secondary	Preterm birth	Birth of a fetus delieved after 28 and before 37 completed weeks of gestational age in participants confirmed ongoing pregnancy	28-37 weeks of pregnancy
Secondary	Birth weight	Including low birth weight (defined as weight <2500 gm at birth), very low birth weight (defined as < 1500 gm at birth), high birth weight (defined as > 4000 gm at birth) and very high birth weight (defined as > 4500 gm at birth).	within 2 weeks after live birth
Secondary	Large for gestational age	Birth weight >90th centile for gestation, based on standardised ethnicity based charts.	within 2 weeks after live birth
Secondary	Small for gestational age	Less than 10th centile for gestational age at delivery based on standardised ethnicity based charts.	within 2 weeks after live birth
Secondary	Congenital anomaly	Any congenital anomaly will be included diagnosed by physical examinition, ultrasound or necessary testing (including CT, X-ray etc.)	within 2 weeks after live birth
Secondary	Perinatal mortality	Fetal or neonatal death occurring during late pregnancy (at 28 completed weeks of gestational age and later), during childbirth, or up to seven completed days after birth.	within 2 weeks after live birth
Secondary	Moderate/severe ovarian hyperstimulation syndrome (OHSS)	exaggerated systemic response to ovarian stimulation characterized by a wide spectrum of clinical and laboratory manifestations. It is classified as mild, moderate, or severe according to the degree of abdominal distention, ovarian enlargement and respiratory hemodynamic, and metabolic complications. Diagosised by ultrasound, blood testing and physical examination according the Chinese Medical Guildline.	From date of controlled ovarian hyperstimulation until the date of oocyte retrieval, assesses about 14-16 days.
