|---|---|---|---|
| Primary | Clinical pregnancy rate | 7 weeks gestation | The fetal heart beat in an intrauterine gestational sac under ultrasound will be defined as clinical pregnancy. |
| Secondary | Oocyte maturation rate | 30 and 46 hours after oocyte retrieval | Oocyte maturation rate (%): number of MII oocytes/ number of oocytes retrieved. |
| Secondary | Fertilization rate | 30 and 46 hours after oocyte retrieval | Fertilization rate (%): number of oocytes fertilized/ number of oocytes retrieved. |
| Secondary | Cleavage rate | 24 hours after ICSI | Cleavage rate (%): number of cleavages/ number of 2PN embryos. |
| Secondary | Day 3 embryo rate | 72 hours after ICSI | Day 3 embryo rate (%): number of Day 3 embryos / number of 2PN embryos. |
| Secondary | Good quality embryo rate at cleavage-stage | 72 hours after ICSI | Good quality embryo rate at cleavage-stage (%): number of good quality embryos at cleavage-stage / number of 2PN embryos. |
| Secondary | Number of cycles with available embryo | 72 hours after ICSI | Available embryos will be defined as three days after oocyte retrieval with containing more than 4 cells and grade 1 to 2 or containing 4 cells with a grade of 1. |
| Secondary | Blastulation rate | 144 hours after ICSI | Blastulation rate (%): number of blastocysts / number of 2PN embryos. |
| Secondary | Biochemical pregnancy rate | 4 weeks gestation | A serum β-hCG level above 5 IU/L, which is performed 12 days after embryos transfer, will be defined as biochemical pregnancy. |
| Secondary | Implantation rate | 7 weeks gestation | The implantation rate will be defined as the number of gestational sacs seen on the ultrasound divided by the total number of embryos transferred. |
| Secondary | Miscarriage rate (at first trimester) | 28 weeks gestation in maximum | Miscarriage at first trimester will be defined by any positive pregnancy test that result in a loss of pregnancy before 12 weeks gestation. |
| Secondary | Cumulative pregnancy rate | 1-2year | Cumulative pregnancy rate will be defined as clinical pregnancies with intrauterine fetal heart beat detected divided by the number of retrieval cycles whose embryos are all transferred. |
| Secondary | Preterm birth rate | 1-2year | Preterm birth means the baby is born before the 37th week of pregnancy in China. |
| Secondary | Newborn birth weight | 1-2year | Newborn birth weight |
| Secondary | Neonatal complication rate | within one month after labor | We will collect complications that occur in the neonate including admission to the neonatal intensive care unit (NICU), hospitalization, etc. |
| Secondary | Live birth rate | 1-2year | Live birth rate(%): number of live birth/ transferred cycle. |
