Experimental: Early Embryo Viability Assessment + Morphological Grading
Embryos of subjects randomized in this group were assessed using Early Embryo Viability Assessment (Eeva) System and morphological grading to identify optimal embryos for transfer.
|
Device: Eeva
Embryos of subjects randomized in this group were assessed using Eeva System and morphological grading to identify optimal embryos for transfer. |
No Intervention: Morphological Grading
Embryos of subjects randomized in this group were assessed only using morphological grading to identify optimal embryos for transfer.

- Implantation Rate [ Time Frame: Gestational Weeks 5 to 8 ]Implantation rate was calculated by dividing the number of intrauterine gestational sacs by the number of embryos transferred multiplied by 100.
- Clinical Pregnancy Rate [ Time Frame: Gestational Weeks 5 to 8 ]Clinical pregnancy was confirmed by the presence of a gestational sac with heartbeat as assessed by ultrasonography. Clinical pregnancy rate was measured as the number of clinical pregnancies divided by number of embryo transfer (ET) cycles multiplied by 100.
- Number of Subjects With Ongoing Pregnancy Status [ Time Frame: Gestational Weeks 10 to 12 ]Ongoing pregnancy was defined as having a positive fetal heart beat (FHB) as assessed by ultrasonography at gestational week 10-12. Number of subjects with ongoing pregnancy status has been reported, where "Yes" indicates participants with positive ongoing pregnancy status and "No" indicates participants with negative ongoing pregnancy status .
- Multiple Pregnancy Rate [ Time Frame: Gestational Weeks 5 to 8 ]Multiple pregnancy rate was defined as a clinical pregnancy with greater than equals to (>=) 2 fetal sacs as assessed by ultrasonography. Multiple Pregnancies rate was measured by number of multiple pregnancies divided by number of embryo transfer cycles multiplied by 100.
- Utilization Rate [ Time Frame: Day 3 or Day 5/6 of embryo culture ]Utilization rate was defined as the sum of number of transferred and frozen embryos divided by number of normally fertilized oocytes multiplied by 100.
- Spontaneous Miscarriage Rate [ Time Frame: Gestational Weeks 10 to 12 ]Spontaneous miscarriage rate was measured by the number of spontaneous miscarriages as communicated during medical appointment or by telephone contact divided by number of clinical pregnancies multiplied by 100.
- Eeva Conformity in Early Embryo Viability Assessment + Morphological Grading Group for Day 3 Embryo Transfer (ET) [ Time Frame: Day 3 of embryo culture ]Eeva Conformity was reported as the number of subjects who were compliant to use Eeva in embryo assessment in the "Early Embryo Viability Assessment + morphological grading" group. Eeva-compliance subgroup refers to subjects whose embryos were assessed by embryologists following the recommendation of Eeva system and the instructions for use (IFU) of Eeva. Subgroup analysis revealed a high incidence of Eeva noncompliance in the experimental group, which compromised the quality of this study. Only "Early Embryo Viability Assessment + Morphological Grading" reporting arm was applicable for this outcome measure.
- Eeva Conformity in Early Embryo Viability Assessment + Morphological Grading Group for Day 5/6 Embryo Transfer (ET) [ Time Frame: Day 5/6 of embryo culture ]Eeva Conformity was reported as the number of subjects who were compliant to use Eeva in embryo assessment in the "Early Embryo Viability Assessment + morphological grading" group. Eeva-compliance subgroup refers to subjects whose embryos were assessed by embryologists following the recommendation of Eeva system and the IFU of Eeva. Subgroup analysis revealed a high incidence of Eeva noncompliance in the experimental group, which compromised the quality of this study. Only "Early Embryo Viability Assessment + Morphological Grading" reporting arm was applicable for this outcome measure.
