Trial summary

To determine if different serum Progesterone levels on FET day are associated with different clinical pregnancy rates (CPR), and if increasing dosage of vaginal Progesterone in cases of lower serum Progesterone level on FET day can be either beneficial or detrimental regarding the CPR.

About this study

Official title: Is There an Association Between Low Serum Progesterone on the Day of Frozen-thawed Embryo Transfer and a Reduced Clinical Pregnancy Rate After an Artificial Endometrial Preparation: A Randomized Control Trial

To determine if different serum Progesterone levels on FET day are associated with different clinical pregnancy rates (CPR), and if increasing dosage of vaginal Progesterone in cases of lower serum Progesterone level on FET day can be either beneficial or detrimental regarding the CPR.

Read the detailed description

Over the past decade, the use of frozen-thawed embryo transfer (FET) has risen around the globe. There is no consensus which mode of FET is superior, either natural cycle (NC) or artificial cycle (AC) with hormonal replacement therapy (HRT). The latter has become more and more popular because it allows more flexibility in timing of FET and it requires fewer visits for monitoring before the transfer. AC also has the advantage of a more precise control of progesterone (P) exposure, which is of utmost importance for controlling the window of implantation between the embryo and the endometrium. Although FET in AC give excellent results, there is still a need for improvement, as the ideal dose is not individualized to a patient's characteristics and serum P required for optimal cycle outcome haven't been established.

Retrospective studies about P levels on the day of FET in AC cycles showed contradictory results regarding cycle outcomes. Several studies showed that a lower P levels on FET day, or one day prior, are associated with lower clinical pregnancy rate (CPR) or live birth rate (LBR), whereas one study showed that women with higher P on FET day were having lower LBRs. Recently, a prospective study showed that serum P level < 9.2 ng/ml on the day of FET in oocyte reception cycles was associated with a significant lower ongoing pregnancy rate. Considering these previous studies, we wanted to determine if different serum P levels on FET day are associated with different CPR, and if increasing dosage of vaginal P in cases of lower serum P level on FET day can be either beneficial or detrimental.

Questions about this trial

What is this clinical trial studying?

A study testing Progesterone in people with IVF, run by Hillel Yaffe Medical Center at 1 site in Israel.

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 23 Jun 2022. 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 Israel. 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?

Clinical pregnancy rate (time frame: 1 Year per patient). 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 Jun 2022.
