Objectives: This study investigated the potential ameliorative effects of Albizia ferruginea leaves on letrozole-induced polycystic ovarian syndrome (PCOS) in Wistar rats.

Methods: PCOS was induced in 25 female Wistar rats by administering letrozole (1 mg/kg), followed by treatment with 100 and 250 mg/kg body weight A. ferruginea leaf methanolic extract, as well as 1 mg/kg body weight of clomiphene citrate as standard.

Results: An acute toxicity study revealed a toxic dosage of 2,000 mg/kg for the plant extract. The A. ferruginea extract exhibited potent hydroxyl radical scavenging ability. Treatment with A. ferruginea leaf extract improved the irregular estrus cycle and hormonal imbalance. Additionally, the extract administration led to decreased testosterone and increased estradiol levels when compared to the untreated PCOS rat. Furthermore, methanol extract normalizes the levels of insulin receptor substrate (IRS), type 2 17-HSD (HsD17β2), P53, 11a-hydroxylase/17,20-desmolase (CYP11a), and fat mass and obesity-associated (FTO), genes in the cervix of PCOS rats.

Conclusions: Overall, A. ferruginea demonstrated beneficial properties on polycystic ovary circumstances in rats, presenting its potential as a promising treatment for PCOS.
