IVF Hyper-responders: Oocyte Vitrification Compared With Embryo Freezing

Not Applicable
Completed
Conditions
Infertility
Interventions
Procedure: embryo freezing
Procedure: oocyte vitrification
Registration Number
NCT02026193
Lead Sponsor
Rambam Health Care Campus
Brief Summary

The chances to achieve pregnancy after retrieving \>15 oocytes are not good, probably because of bad effect on the endometrium (uterine inner lining). Therefore, in most such cases the investigators prefer to freeze all embryos, and transfer in a thaw cycle. With the introduction of oocyte vitrification (very fast cooling) technology, a new option emerged: to freeze un-fertilized eggs, to be fertilized and used later in a thaw cycle.

The purpose of this study is to compare the outcome of these two approaches.
