What Embryoselection for What Chance of Success ? EmbryoSelect Study
Sponsor: University Hospital, Bordeaux
Summary
The aim of the research is to evaluate the results of the first in vitro fertilization (IVF) attempt according to the type of embryo culture. From the fertilization to the day 2 transfer, embryos are cultured in standard incubator or in a time lapse technology (TLT). TLT offers an uninterrupted culture environment with a morphokinetic evaluation, whereas culture in standard incubator involves discontinuous morphological embryo evaluation. The principal objective is to compare the live birth rate after the fresh embryo transfer, in a cohort of women less than 39 years-old.
Official title: A Randomized Double-blind Trial Evaluating the Live Birth Rate After Transfer of Embryos Cultured in Time Lapse Incubator Compared With Conventional Incubator: Embryoselect

Interventions
Embryo culture in time lapse technology (TLT)
In the TLT group, the selection for transfer was based on morphological and kinetic criteria (with the use of an algorithm). Embryos will be cultured and selected for fresh transfer.
Embryo culture in conventional incubator
For the standard incubation group, the selection for transfer will be based on morphological criteria. Embryos will be cultured and selected for fresh transfer.
