Galactomannan Restore Letrozole Induced Polycystic Ovarian Syndrome (PCOS) in Rat Model

Abstract

Current research aims towards evaluation of the effect of Galactomannan (GM) on letrozole-induced PCOS in adult female Wistar rats. Seven randomized groups of six female rats were made. The rats in all groups were administered with letrozole (1 mg/kg p.o.) for 21 days to induce PCOS. Rats in respective groups were treated with vehicle (10 ml/kg, p.o.), clomiphene citrate (1 mg/kg, p.o.), galactomannan (10, 20, 40 mg/kg, p.o.) and clomiphene citrate + galactomannan (1+20 mg/kg, p.o.) from day 22 to 36. On the last day of treatment i.e., 37th day of the study, blood was withdrawn, serum was separated and was used to assess hormonal and lipid profile. The rats were sacrificed in the late diestrus stage, ovaries were isolated and used for histopathological studies. Cysts in the ovaries of rats in control group was clearly seen after giving letrozole. Treatment either with Galactomannan or clomiphene citrate, significantly decreased blood sugar level, lipid profile, LH and testosterone whereas increased concentration of FSH and AMH was observed at the end of study. Reduced number of ovarian cysts as well as decreased body weight and ovary weight was documented for the possible protective role of galactomannan in PCOS. On the basis of results, galactomannan exerts protective effect in PCOS and could be given as adjuvant treatment with the available pharmacotherapy for the management of PCOS in women.
