NCT05109676

Brief Summary

During an In Vitro Fertilization (IVF) attempt, several embryos are obtained but not all of them can be transferred to the uterus in the same cycle due to the risk of multiple pregnancies. Thus, it is very common for these couples to benefit from cryopreservation. Patients scheduled for frozen embryo transfer (TEC) receive estrogen and progesterone replacement therapy to prepare the endometrium for implantation. Data from the literature recently showed that low progesterone on the day of embryo transfer was responsible for a significantly higher rate of implantation failure and miscarriage.

    Dosage of apparent clearance (CL/F)

    Day of embryo transfer.

Study Arms (1)

Patients having embryo transfert

EXPERIMENTAL

Patients benefit from the usual treatment for frozen embryo transfer with a preparatory cycle of the artificial endometrium: 150 µg of percutaneous estradiol for approximately 11 days and 200 mg of progesterone morning and evening to be taken vaginally for 2 days in case of embryo transfer at day 2 stage, 3 days in case of embryo transfer at day 3 stage, 5 days in case of day 5 embryo transfer or 6 days in case of day 6 embryo transfer.

Other: Questionnaire

Interventions

A questionnaire will be offered to patients and identify the schedules of administration of progesterone, the day and time of blood samples taken as part of the care, the potential adverse events associated with this administration.
