IVF Hyper-responders: Oocyte Vitrification Compared With Embryo Freezing
- Conditions
- Infertility
- Interventions
- Procedure: embryo freezingProcedure: 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.
