Trial summary

Our working hypothesis is that patients undergoing "in vitro" fertilization (IVF) with higher response to ovarian stimulation protocols recover a higher number of oocytes and, this elevated response could be translated into increased incidence of chromosomally abnormal embryos.

About this study

Official title: Influence of Ovarian Stimulation and Embryo Aneuploidy

Our working hypothesis is that patients undergoing "in vitro" fertilization (IVF) with higher response to ovarian stimulation protocols recover a higher number of oocytes and, this elevated response could be translated into increased incidence of chromosomally abnormal embryos. Our objective is to develop a prospective study on healthy young donors, with a previous cycle with high ovarian response (>20 oocytes and/or E2 levels the day of the hCG injection >3000 pg/mL), but without developing mild or severe hyperstimulation syndrome. After signing a proper written consent, these donors would agree to undergo two subsequent stimulation cycles following two different protocols. In one cycle the stimulation pattern would be similar to the previous one, with elevated response and, in another cycle the amount of gonadotropins would be cut down in order to obtain lower ovarian response. Oocytes obtained in each cycle would be donated to anonymous recipients and after fertilization, embryo quality and chromosomal status of the resulting embryos would be evaluated. Preimplantation genetic diagnosis (PGD) will be performed on day-3 embryos and chromosomes 13, 15, 16, 17, 18, 21, 22, X and Y would be analyzed by fluorescence "in situ" hybridization (FISH).

Questions about this trial

What is this clinical trial studying?

A study testing Gonadotrophins and Low dosis Gonadotrophin in people with Aneuploidy, 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?

The sponsor lists 3 inclusion and 3 exclusion criteria. 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 18 Sep 2009. 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.

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?

Aneuploidy rate with two different stimulation protocols. (time frame: three months). 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 NCT00802295, 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 18 Sep 2009.
