Efficacy and safety of simplified follitropin delta dosing in women undergoing intrauterine insemination in Indonesia

Available evidence indicate that Intrauterine Insemination (IUI) cycles with controlled ovarian stimulation (COS) yield better oocyte quality and higher pregnancy rates compared to those without COS in infertile women. As follitropin delta is an improved version of recombinant FSH, its ability to stimulate the development of multiple ovarian follicles is supposedly superior to follitropin alfa. The objective of this study was to evaluate the efficacy and safety of follitropin delta with a simplified dosage equivalent method in Indonesian women undergoing IUI. The design of this study was a retrospective observational study conducted from February 2022 to December 2023 involving 248 IUI cycles at Halim Fertility Center (HFC) IVF Center, Indonesia. Controlled Ovarian Stimulation was performed with follitropin delta with a simplified dosage equivalent method in IUI. From this study, we found that the clinical pregnancy rate (CPR) for IUI was 27.8%. The Ovarian Hyperstimulation Syndrome (OHSS) rates was 0.4%, with 2,9% multiple pregnancies in the follitropin delta with a simplified dosage equivalent method. This study showed no statistically significant differences in pregnancy rates based on age groups and BMI (p=0.288 vs p=0.934). WE conclude that follitropin delta may improve the outcome of intrauterine insemination in women undergoing IUI.
