Embryo Aneuploidies and Ovarian Stimulation

Phase 4
Completed
Conditions
Embryo Aneuploidies
Interventions
Procedure: Preimplantation Genetic Diagnosis
Registration Number
NCT00707525
Lead Sponsor
Instituto Valenciano de Infertilidad, IVI VALENCIA
Brief Summary

There is a considerable concern about the effects of controlled ovarian hyperstimulation (COH) for In Vitro Fertilization- Embryo Transfer (IVF-ET) on embryo quality and on the incidence of chromosomal abnormalities in oocytes and embryos.

The main question remaining is if COH may increase the aneuploidies rate in young and healthy women. Therefore, the primary endpoint of the present study is to analyse the incidence of chromosomal abnormalities in this group of patients (oocyte donors), either in oocytes obtained after a natural cycle or in those retrieved after a COH cycle. To get rid of the male factor influence, donated sperm will be used.

2Preimplantation Genetic DiagnosisStimulated cycle oocyte donation. * Long protocol down-regulation with a GnRH agonist, starting on the midluteal phase of the previous cycle with leuprolide acetate (0.2mg/day). * Once evidence of downregulation is documented, leuprolide will be halved to 0.1 mg daily. * COH with be carried on with gonadotropins (150UI/day of rFSH and 75 UI/day of HP-hMG). The dose can be adjusted according to ovarian response as judged by ultrasound and by serum oestradiol (E 2 ) concentrations.
