What participants receive

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

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. number of retrieved oocytes

    Measured: at the ovarian puncture, 36 hours post HCG administration

Secondary outcomes (5)
  1. pregnancy rate

    Measured: at pregnancy test and at 6 Week US examination

  2. delivery rate

    Measured: 9 months later

  3. number of obtained embryos

    Measured: 2 days after in vitro fertilization

  4. duration of FSH administration

    number of days of administration

    Measured: at the end of ovarian stimulation usually after a mean of 12 days of administration

  5. Total FSH dose

    daily dose x number of days of administration

    Measured: at the end of ovarian stimulation usually after a mean of 12 days of administration

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing 17beta-estradiol in people with Infertility, run by Gemer at 1 site in France.

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 4 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 12 Dec 2011. 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 France. 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?

number of retrieved oocytes (time frame: at the ovarian puncture, 36 hours post HCG administration). 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 NCT01489852, 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 12 Dec 2011.
