Fixed 3.66 mcg Rekovelle (follitropin delta) for ovarian stimulation before intrauterine insemination

Using a Fixed Dosage of Follitropin Delta for Ovarian Stimulation for Intrauterine Insemination: Rekovelle for Intrauterine Successful Experience (RISE)

Phase 2 Interventional Centre Hospitalier Intercommunal Creteil · NCT07153367

This test tries a fixed 3.66 mcg dose of Rekovelle (follitropin delta) to stimulate the ovaries of women 18–38 with regular cycles undergoing their first IUI to encourage two follicles and reduce the chance of multiple pregnancy.

What this trial studies

This Phase 2 interventional study gives a single fixed dose of 3.66 mcg follitropin delta (Rekovelle) to normo-ovulatory women undergoing their first intrauterine insemination. Treatment is started at inclusion and follicular development is monitored beginning on day 9 and then every two days until two mature follicles develop. Ovulation is triggered with hCG and insemination is performed 24–36 hours later. The main goal is to achieve a controlled bifollicular response while minimizing cycle cancellations and the risk of multiple pregnancies.

Who should consider this trial

Good fit: Ideal candidates are normo-ovulatory women aged 18–38 with BMI 18–29, regular menstrual cycles, at least one healthy fallopian tube, a normal uterine cavity, and who are undergoing their first IUI.

Not a fit: Women with PCOS, severe male-factor infertility (very low sperm counts), prior excessive response to gonadotrophins or OHSS history, major chronic disease contraindicating stimulation, or certain gynecologic or genetic conditions are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, this approach could simplify dosing, speed time to pregnancy, and lower the risk of multiple pregnancies and treatment cancellations.

How similar studies have performed: Rekovelle has demonstrated efficacy for controlled ovarian stimulation in IVF/ICSI and at least one recent study supports its use in IUI, but use of this specific fixed 3.66 mcg dose for first-attempt IUI is being specifically confirmed here.
