Brief summary

Compare, in young patients with In vitro fertilization (IVF), the rate of embryo implantation by early culture transfer (J2-J3) between 2 groups of patients: normo responders vs. poor responders.

Inclusion criteria

* IVF patient managed with or without ICSI between 01/01/2014 and 30/06/2015 in one of the two study centres * Age \< 35 years old * Fresh transfer of at least one embryo between D2 and D6 * patients who have already received one or more transfer attempts.

Exclusion criteria

* No fresh transfer (Freeze All, segmentation failure, stimulation failure) * Double successive embryo transfer (e. g. J3-J5). We did not retain these cases because if only one of the 2 embryos is implanted, it is not possible to know which transfer it corresponds to. * Maternal serum FSH determination \< 4 IU/ml at D3 in the baseline balance sheet (hypogonadotropic hypogonadism)

Design outcomes

Primary

MeasureTime frameDescription
The embryo implantation rate at 5 weeks after transfer is defined by the presence of an embryo with objective cardiac activity by ultrasound5weeksThe embryo implantation rate corresponds to the number of embryos with cardiac activity found on the number of embryos transferred
