About this study

The aim of this study is to evaluate the use of a fixed dose of 3.66 mcg of follitropin delta (Rekovelle) on ovarian response during ovarian stimulation for intrauterine insemination (IUI). The assumption is that this fixed dose will be effective while minimizing the risk of multiple pregnancies. A recent study demonstrated the efficacy of follitropin delta for ovarian stimulation in IUI, and it has been approved in France for controlled ovarian stimulation in assisted reproductive techniques such as in vitro fertilization (IVF) and IVF with intracytoplasmic sperm injection (ICSI). With an adapted dose of Rekovelle for patients with regular menstrual cycles, ovarian stimulation is optimized from the first attempt, promoting the development of two follicles to improve pregnancy chances while reducing the risk of multiple pregnancies. This approach aims to achieve pregnancy faster and provide a more comfortable treatment experience.

Read the detailed description

Intrauterine insemination (IUI) is a frequently used step in the management of unexplained infertility or mild fertility disorders. In normal-weight patients, the main objective of ovarian stimulation in IUI is to obtain a controlled ovarian response, ideally bifollicular.

Moreover, the main risks currently associated with IUI are multiple pregnancies and iatrogenic complications (cycle cancellation due to insufficient response or excessive response to stimulation more than 3 follicles). It is therefore essential to optimize stimulation treatment protocols to ensure IUI under the best possible conditions.

Due to a precise dose adjustment with Follitropin Delta, the product used in the study (REKOVELLE), for normo-ovulatory patient, an optimal response (bifollicular response) is expected for the majority of patients from the first stimulation. This goal will also facilitate quicker pregnancy attainment and reduce the risk of drop-out and insémination annulation The hypothesis is that this dosage would be efficient and also minimize the risk of multiple pregnancies During the screening visit, the investigator checks the patient's eligibility and informs her about the RISE study. At the inclusion visit, written informed consent is obtained, and the Rekovelle® treatment is explained and initiated. Monitoring visits start on day 9 and then every 2 days until two mature follicles develop. Ovocyte maturation is triggered with an hCG injection, followed by insemination 24 to 36 hours later, performed according to routine care. Follow-up visits occur at 6-8 weeks and 13 weeks post-insemination.

What participants receive

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

  • REKOVELLE (Follitropin Delta)Drug

    Each patient will start the ovarian stimulation with a fixed dose of 3,66 mcg of Rekovelle ® on day 4 of the natural cycle (Stimulation day 1-S1). The stimulation period will last a maximum of 13 days.

    Patients will be regularly evaluated to monitor the response to stimulation with ultrasound scan and blood sampling

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 8 inclusion and 32 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: looking for participants now, as of the sponsor's last update on 8 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Aroua Ben Guirat (+33157023710, aroua.benguirat@chicreteil.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of cycles with two mature follicles (total of two ovaries) at the stage of triggering ovulation (time frame: up to 9 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 8 Apr 2026.
