Objective: To investigate potential reproductive effects of Pterocarpus marsupium methanolic extract on testosterone propionate induced Polycystic Ovarian Syndrome (PCOS) in female albino rats.Methodology: PCOS was induced in female albino rats by daily injecting testosterone propionate for 15 days intraperitoneally. Animals are divided into five groups with six rats per group. Group 1: Control group received olive oil, Group 2: Testosterone propionate+natural recovery, Group 3: Testosterone propionate + a dose of clomiphene citrate (standard), Group 4 and 5: Testosterone propionate + low dose (200mg/kg) and high dose (400mg/kg) b.w respectively for 15 days. Various biochemical and histopathological investigations were assessed. Results: Methanol extract of Pterocarpus marsupium was able to exert its protective effect successfully by restoring all the parameters to normal and diminishing the cysts found in ovaries. Conclusion: Pterocarpus marsupium showed potential reproductive effects on testosterone propionate induced PCOS female albino rats and could be used as an alternative therapy in the treatment of PCOS.
