This study aimed to investigate the protective effect of astaxanthin (AS) on 3-nitropropionic acid (3-NPA) induced experimental ovarian damage in rats. Thirty two female Wistar rats were divided into four equal groups of eight each: control group (C); phosphate-buffered saline, AS group; AS (80 mg/kg) for 14 days, 3-NPA group; 3-NPA (6.25 mg/kg) twice a day for 7 days, 3-NPA + AS group; administered AS (80 mg/kg) for 14 days and 3-NPA (6.25 mg/kg) for 7 days. All injections were administered intraperitoneally. Rats were fed ad libitum with standard rat chow and tap water. Plasma and ovarian tissue total antioxidant capacity (TAC), total oxidant capacity (TOC) and oxidative stress index (OSI) levels, whole blood reduced glutathione (GSH), plasma paraoxonase 1 (PON1) activity, lipid profile, malondialdehyde (MDA), nitric oxide (NO), total sialic acid (TSA) and total thiol(TT) concentrations were analysed spectrophotometrically. Also, ovarian tissue histopathology was performed. We observed 3-NPA-induced histopathological ovarian damage significantly decreased the TAC (p < 0.001), GSH (p < 0.001), high-density lipoprotein (p < 0.01) levels and PON1 activity (p < 0.01), and significantly increased TOC, OSI (p < 0.001), MDA, NO, TSA, cholesterol, low-density lipoprotein (p < 0.01) and triglyceride (p < 0.05) levels. In conclusion, cotreatment with AS restored the negative effect of 3-NPA on all biochemical parameters cited above and improved the histopathological ovarian damage. Ovarian toxicity induced by 3-NPA might be due to oxidative damage. The improvement of AS seems to be related to itsantioxidant properties.
