Is this trial a fit for you?
✓Likely a good fit
Infertile women aged 35-44 undergoing IVF who have DOR (POSEIDON group 4: FSH <10 IU/L and AMH >1.2 ng/mL) and are treated at The Center for Human Reproduction.
✕Probably not a fit
Some participants may not experience improved IVF outcomes or any benefit from G-CSF therapy.

What this trial studies
This is a randomized, double-blind, placebo-controlled Phase 4 study enrolling 140 women with diminished ovarian reserve (POSEIDON group 4) undergoing IVF. Participants receive either Neupogen G-CSF 300 μg or saline in five injections every other day starting in the early luteal phase, targeting ovarian response. The goal is to determine if G-CSF can improve IVF success metrics in this specific population. The study is conducted at The Center for Human Reproduction in New York, with the lead sponsor overseeing the trial. Safety and efficacy data will inform whether G-CSF could become a therapeutic option for DOR in IVF settings.
Why it matters
Potential benefit: If successful, participants may have improved IVF outcomes and higher chances of achieving pregnancy.
How similar studies have gone: Previous research on G-CSF for DOR has yielded mixed results, making this study among the more rigorous attempts in a defined POSEIDON subgroup.
