About this study

Official title: Endometrial Gene Expression in Different Protocols of Endometrial Preparation

Do differences in endometrial gene expression exist after different protocols of endometrial preparation for embryo transfer? The recent apparition of endometrial receptive arrays technology let us know if endometrial is receptive or not in patients with some problems of infertility as implantation failure, for that we want to know if this technology would tell us if the different kind of protocols for endometrial preparation origin differences that could explain some of the founded results.

Read the detailed description

Do differences in endometrial gene expression exist after different protocols of endometrial preparation for embryo transfer? The clinical results in different publications showed different results, some of them described the natural cycle superior as the substituted cycles, and in contrast other large series showed superior results in substituted cycles than natural but with an increased of pregnancies losses. The recent apparition of endometrial receptive arrays technology let us know if endometrial is receptive or not in patients with some problems of infertility as implantation failure, for that we want to know if this technology would tell us if the different kind of protocols for endometrial preparation origin differences that could explain some of the founded results.

What is being measured

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

  1. Endometrial receptivity

    Total RNA was extracted using the TRIzol method according to the manufacturer's recommendations (Life Technologies). Approximately 1-2 mg of total RNA was obtained per milligram of endometrial tissue. The RNA quality was assessed by loading 300 ng of total RNA onto an RNA LabChip and was analyzed in an A2100 Bioanalyzer (Agilent Technologies). Only samples with a RNA integrity number >7 were selected for microarray analysis.

    Sample preparation and hybridization was adapted from the Agilent technical manual. Hybridized microarrays were scanned in an Axon 4100A scanner (Molecular Devices), and the data were extracted with the GenePix Pro 6.0 software (Molecular Devices). The ERA microarray validation has been previously published. Reverse transcriptase-polymerase chain reaction (PCR) was performed for four selected up-regulated genes: GPX3, FXYD2, SPP1, and MT1G.

    The ERA gene expression values were preprocessed, normalized, and statistically analyzed. Briefly, the half background

Questions about this trial

What is this clinical trial studying?

An observational study of Endometrial, run by IVI Madrid 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 7 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 23 Feb 2016. 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?

Endometrial receptivity (time frame: 4 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Feb 2016.
