Brief Summary

This study is to compare the efficacy in embryo selection based on morphology alone compared to morphology and non-invasive preimplantation genetic testing for aneuploidy (NIPGT-A) in infertile women undergoing in vitro fertilization (IVF). We supposed the embryo selection based on morphology and NIPGT-A results in a higher live birth rate and a lower miscarriage rate in IVF as compared with that based on morphology alone. Therefore we would like to conduct a double-blind randomized controlled trial. Infertile women undergoing IVF will be enrolled. The spent culture medium (SCM) of each blastocyst will be frozen individually. They will be randomized into two groups: (1) the intervention group based on morphology and NIPGT-A and (2) the control group based on morphology alone. In the control group, blastocysts with the best quality morphology will be replaced first. In the intervention group, blastocysts with the best morphology and euploid result of SCM will be replaced first.The primary outcome is a live birth per the first embryo transfer. We would like to compare live birth rates and miscarriage rates between the two groups.

    Number of pregnancies leading to live birth within 6 months of randomization

  • Time to pregnancy

    1 year

  • Positive urine pregnancy test

    Positive urine pregnancy test 14 days after embryo transfer

  • Clinical pregnancy

Study Arms (2)

intervention group using morphology and NIPGT-A

ACTIVE COMPARATOR

Both morphology and NIPGT-A result will be used to prioritize the sequence of embryo transfer in the intervention group.

Genetic: Non-invasive Preimplantation genetic testing for aneuploidy status

control group based on morphology alone

NO INTERVENTION

Morphology only will be used to prioritize the sequence of embryo transfer in the intervention arm.

Interventions

In the intervention group, comprehensive chromosome screening using NGS will be performed according to the recommendations of the company in all SCM samples. Sequence of replacement shall be altered by the NiPGT result after morpholgy.
