Can a simpler fertility drug dose match the standard for IUI success?
NCT ID NCT07801781
First seen Sep 03, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This study compares two follicle-stimulating hormones, follitropin delta and follitropin alfa, used to stimulate the ovaries in Indonesian women under 40 undergoing intrauterine insemination (IUI) for infertility. Researchers will review medical records from a fertility center to see whether a simplified follitropin delta dosing regimen leads to similar clinical pregnancy rates as the conventional follitropin alfa treatment. They will also check for differences in multiple pregnancy and ovarian hyperstimulation syndrome rates. The study does not assign treatments; it looks back at cycles already completed as part of routine care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Follitropin delta (a follicle-stimulating hormone) compared with follitropin alfa (GONAL-F)
- What this could lead to
- If follitropin delta with a simplified dosing works as well as follitropin alfa, it could offer a more convenient and equally effective option for ovarian stimulation in IUI.
- What could go wrong
- This is a retrospective review of past records, not a controlled experiment, so differences between groups may reflect patient factors rather than the drugs. Results may not apply beyond this Indonesian clinic.

Who is studied
The study population consisted of women younger than 40 years who underwent controlled ovarian stimulation followed by intrauterine insemination (IUI) at Halim Fertility Center, Indonesia, between January 2020 and December 2022. Participants had infertility associated with unexplained infertility, anovulation, mild male-factor infertility, or combined infertility factors and met the predefined eligibility criteria. Women were classified according to the ovarian stimulation received: follitropin alfa or follitropin delta.
