The study looked at chicken ovarian cells and found that a synthetic IGF‑1 molecule (LR3‑IGF‑I) can boost the hormones these cells make when they’re also given LH or FSH, but the effects vary with the cell’s stage and over time. This is basic bird biology and doesn’t give any direct advice you can use for human health or performance.
