EMBRYO TRANSFER (ET), LUTEAL PHASE SUPPLEMENTATION AND POSSIBLE CRYOPRESERVATION OF SUPERNUMERARY EMBRYOS

In our centres, the transfer of a single embryo, whether or not associated with advanced embryo selection techniques the elected adopted policy (Ubaldi et al., 2015).

The viable embryos obtained are transferred into the uterine cavity through a thin catheter.

The embryo transfer is performed in the operating theatre. This procedure is simple and therefore does not require anesthesia or hospitalization. Support of the luteal phase is ensured by vaginal administration of natural progesterone.

Embryo freezing is allowed in all cases where the transfer the embryos is not allowed due to a serious and documented state of health of the woman, not foreseeable at the time of fertilization (Constitutional Court ruling no.151/2009). Any embryo that is not transferred into the uterus is, therefore, cryopreserved, until future implantation.

 

 

Freeze all” policies involving the cryopreservation of all the material obtained (oocytes and/or embryos) may be adopted if the clinician does not consider the endometrium suitable for transfer, if there is a risk of OHSS onset or if the couple wishes to be informed about the state of health of the embryos obtained. The “freeze all” strategy, when combined with an efficient cryopreservation program, has demonstrated high efficacy in terms of cumulative clinical results and proven safety in terms of minimizing the risks related to a IVF treatment, even when applied to patients with poorer prognosis (Ubaldi et al., 2015).
