Brief Summary
The aim of the study is to determine if collapsing an embryo (or making it fold compactly by taking away its fluid) before the transfer in the uterine cavity improves pregnancy rates in assisted reproductive technology (ART). Women coming to our ART center will be randomized in two groups : the collapsing group and a control group. Pregnancy rates will be compared in the two groups. A biomarker (cell free DNA) will also be determined in each group and correlated to pregnancy occurrence.
