Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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)

Primary outcomes

  1. The embryo implantation rate at 5 weeks after transfer is defined by the presence of an embryo with objective cardiac activity by ultrasound

    Time frame: 5weeks

    The embryo implantation rate corresponds to the number of embryos with cardiac activity found on the number of embryos transferred
