The aim of this study is to evaluate the outcomes of single embryo transfer in patients with good ovarian reserve in the IVF program using time-lapse microscopy. This is a retrospective cohort study in a private IVF center in Russia. Comparison was done between 90 IVF cycles using time-lapse (study group) and 113 IVF cycles using standard culture (control group). Within each group, subgroups were selected with selective transfer of one embryo for 5 days (5SET) and elective transfer of one embryo for 5 days (5eSET). The primary outcome of the study was pregnancy rate. Secondary outcomes were miscarriage rates, live birth. Pregnancy rate did not significantly differ between the groups - 64.2% in the study group and control group. In the study group, the delivery rate was 54% in the subgroup 5eSET and 51.1% in the subgroup 5SET ( p = .940). In the control group, the type of the embryo transfer significantly influenced on the delivery rate: in the 5eSET subgroup the birth rate was 54.4%, and in the 5SET subgroup it was 34.3% ( p = .055; by Fisher's exact method p = .052). There were no adverse effects of the intervention. Selection of a single blastocyst based on information derived from time-lapse monitoring can help embryo selection for transfer. |
