About this study

Official title: Incidence of EmbyoO Aneuploidies in Natural Versus Stimulated Cycles in the Same Women.

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Preimplantation Genetic DiagnosisProcedure or surgery

    Preimplantation Genetic Diagnosis (PGD) is performed on the embryos resulting from these natural and stimulated cycles.

Study groups in NCT00707525
Study groupRoleWhat they receive
1No interventionNatural cycle oocyte donation
2Active comparatorStimulated 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.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Preimplantation Genetic Diagnosis in people with Embryo Aneuploidies, run by Instituto Valenciano de Infertilidad, IVI VALENCIA at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Mar 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Embryo aneuploidies (time frame: 2 cycles). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00707525, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Mar 2010.
