Improvement of Live Babies Rates After ICSI, Using cpFT (FERTICSI)

Improvement of Live Babies Rates After ICSI, Using cpFT: Multicenter Prospective Randomized Clinical Trial

Demonstrate the improvement of the live births rate after ICSI by supplementing the pre-ICSI incubation medium of oocytes and that of preimplantation embryos with cpFT at the 1st embryo transfer for women under 37 years old.

Supplementation of the incubation medium with cFEE should improve the implantation rate and ART outcome. As in France ICSI is widely used to achieve good fertilization rates, we decided to use ICSI to fertilize the egg, and the peptide: to improve chromosome segregation during meiosis, and to improve in vitro embryogenesis after ICSI. Hence the protocol includes an oocyte preincubation step prior to ICSI and a co incubation of the embryo with the molecule during blastocyst formation. Hence our protocol includes: - a preincubation of the decoronized oocytes with the peptide prior to ICSI, and - a coincubation of the developing embryo with the molecule. The principal criteria will be the live baby rate after the first embryo transfer (using the best embryo). As the oocyte loses its strength as the women is getting older, the main criteria will be evaluated for women under 37 years old. Randomization: every couple will be randomly assigned to the Control or the Treated group. Treated group: After egg retrieval, the oocyte will be decoronized and incubated prior to ICSI procedure into CSCM-C (Irvine) medium supplemented with the molecule. Control group: similar protocol of incubation but without the molecule. After ICSI the zygote will be incubated until the blastocyste stage in CSCM-C medium (Irvine). Embryo transfer will be limited to only one blastocyst, fresh or delayed after cryopreservation.

there will be two groups: one treated by supplementation of the culture medium with 1 Micromolar of the molecule, the other being the control group.

Upon retrieval, the oocyte will be decoronized and incubated prior to ICSI procedure into CSCC-M medium supplemented with the molecule. After ICSI, the zygote will be incubated in CSCM-C medium supplemented with the peptide.

Demonstration of the improvement in the rate of live births after ICSI by supplementing the pre-ICSI incubation medium of oocytes and that of preimplantation embryos with cpFT (1µM) during the 1st embryo transfer in women under 37 years of age.

The measure evaluates the rate and number of fertilized eggs over the total number of metaphase 2 oocytes.

The embryos will be kept in an incubator with an embryoscope so that their cleavage sequences will be registered "when possible". The criteria will analysis the cleavage sequences of all embryos during preimplantation embryogenesis.

All the embryos that will reach the blastocyst stage will be evaluated according to the Gardner criteria.

The percentage of Good and Top embryos after thawing will be compared to the grading for the same embryo before cryopreservation according to Gardner criteria

It reports the percentage of morphological ultrasounds showing an abnormality in the fetus morphology on the total number of morphological ultrasounds performed for all the pregnancies depending of the study.

It reports the percentage of neonatal baby examination showing an abnormality over the total number of neonatal baby examination performed for all the babies who will born during the study.

It reports the percentage of one year old baby examinations showing an abnormality over the total number of one year old baby examinations performed for all the babies who will born during the study.
