Infertility, Insemination
Conditions
Brief summary
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.
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.
Interventions
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
