1 Cumulative Live Birth Rates After Cleavage-stage Versus Blastocyst-stage Embryo Transfer: A Multicenter, Prospective, Randomized Controlled Trial

The aim of this RCT is to compare differences in the efficacy and safety between cleavage-stage embryo transfer and blastocyst-stage embryo transfer in IVF/ICSI treatment cycle, taking into account of subsequent vitrified embryo transfers. Subjects with 3 or more transferrable cleavage embryos will be randomized to the cleavage-stage or blastocyst-stage embryos transfer group. The primary outcome is cumulative live birth rate (CLBR) per patient until the first live birth from one initiated oocyte retrieval cycle, calculated using outcomes from the first three embryo transfers within 1 year after randomization.

NCT03152643 Infertility Procedure: blastocyst-stage embryo transfer Procedure: cleavage-stage embryo transfer
MeSH:Infertility
HPO:Infertility

Primary Outcomes

Description: Cumulative live birth rate (CLBR) is defined the first live birth per patient from one initiated oocyte retrieval cycle(Calculated using outcomes from the first three embryo transfers within 1 year after randomization). Live birth is defined as delivery of any neonate ≥24 weeks gestation with heart beat and breath.

Measure: cumulative live birth rate

Time: 30 months

Secondary Outcomes

Description: Biochemical pregnancy is defined as a serum β-HCG level of at least 25 IU/L 14 days after embryo transfer.

Measure: biochemical pregnancy rate

Time: 30 months

Description: Clinical pregnancy is defined by the presence of intrauterine gestation sacs at 30-35 days after embryo transfer.

Measure: clinical pregnancy rate

Time: 30 months

Description: Ongoing pregnancy is defined as a viable pregnancy at 12 weeks gestation.

Measure: ongoing pregnancy rate

Time: 30 months

Description: Pregnancy loss is defined as a pregnancy that results in a spontaneous abortion or therapeutic abortion that occurred throughout pregnancy.

Measure: Pregnancy loss rate

Time: 30 months

Description: Number of patients with moderate or severe OHSS/ number of COS cycles.

Measure: moderate or severe OHSS rate

Time: 12 months

Description: diagnosed by ultrasound examination or laparoscopic surgery visualizing more than or equal to 1 gestational sacs outside the uterus or by abnormally increasing serum hCG level without sonographic visualization and the absence of chorionic villi inside the uterus after uterine curettage, which was treated by methotrexate.

Measure: ectopic pregnancy

Time: 24 months

Description: the ratio of males to females in the newborns

Measure: sex ratio

Time: 30 months

Description: Number of multiple pregnancies / number of clinical pregnancies.

Measure: multiple pregnancy

Time: 30 months

Description: Number of pregnancies with complications / number of pregnancies; ;number of live births with neonatal complications / number of live births

Measure: incidence of obstetric and perinatal complications

Time: 30 months

Description: structural or functional anomalies that occur during intrauterine life and can be identified prenatally, at birth or later in life.

Measure: congenital anomalies

Time: 30 months

Description: the number of gestational sacs detected with sonography at 6 weeks of pregnancy/the number of embryos transferred

Measure: implantation rate

Time: 30 months

Description: Weight of newborns at delivery

Measure: Birth weight

Time: 30 months
