What participants receive

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

  • Ovarian punctureProcedure or surgery

    Donors and patients are subjected to ovarian puncture as part of their donation procedure or IVF treatment. Oocyte are retrieved in this procedure along with granulosa and cumulus cells. Donors and patients sign an informed consent in order to donate their granulosa and cumulus cells for the study.

    Measured: 4 years

  9. Embryo quality

    Embryo quality at day 3 of embryo development (of each embryo of the cohort). Quality assessed according to ASEBIR (ASEBIR = "Asociación Española para el estudio de la Biología de la Reproducción" = Spanish society for reproductive biology) criteria. Embryo quality grade A to D.

    Measured: 4 years

  10. Daily and total dose of FSH (FSH = follicle stimulating hormone)

Questions about this trial

What is this clinical trial studying?

A study testing Ovarian puncture in people with Infertility, run by Vida Recoletas Sevilla at 2 sites 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 9 inclusion and 5 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 13 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Expression level of Substance P (SP) (time frame: 4 years). The study lists 9 primary outcomes in all. 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 NCT02877992, which also lists 2 linked publications.

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 13 Feb 2020.
