Cisplatin (CP) treatment causes damage in the male reproductive system. Rutin (RUT) is a naturally occurring flavonoid glycoside that has antioxidant and anti-inflammatory properties. This study aimed to investigate effects of RUT against cisplatin-induced reproductive toxicity in male rats. Twenty-one adult male Sprague Dawley rats were used. The control group received physiological saline with oral gavage during 14 days, and physiological saline was injected intraperitoneally (IP) in 10th days of study. CP Group received physiological saline during 14 days, and 10 mg kg CP was injected IP in 10th day. RUT + CP group received RUT (150 mg kg ) during 14 days, and 10 mg kg CP was injected IP in 10th day. Spermatological parameters (including motility, cauda epididymal sperm density, dead sperm percentage and morphological sperm abnormalities), biochemical (MDA, GSH, GSH-px, SOD and CAT), histological (H&E dye) and immunochemistry evaluations of testicles were evaluated. CP treatment caused damage on some spermatological parameters, increased the oxidative stress and induced testicular degeneration and apoptosis when compared to the control group. However, RUT treatment mitigates these side effects when compared to the CP alone group. IT is concluded that RUT treatment may reduce CP-induced reproductive toxicity as a potential antioxidant compound.

Paracetamol (PRC) is a nonsteroidal anti-inflammatory drug used widely as a painkiller for various diseases and as the symptomatic flu cure in several countries worldwide. PRC toxicity may occur under conditions of the overdose usage. Chrysin (CR) is a flavonoid that is naturally present in several plants, honey and propolis. The aim of this study was to investigate the effects of CR (at the doses of 25 mg kg and 50 mg kg ) pre-treatment over seven consecutive days against PRC-induced reproductive toxicity in male rats. Our results showed that PRC toxicity decreased the sperm motility, and increased dead sperm rate, abnormal sperm cell rate, apoptosis and MDA levels in testicular tissues. Pre-treatment with CR at the dose of 25 and 50 mg kg for 7 days mitigated side effects of acute PRC toxicity in male reproductive system proportionally in a dose-dependent manner. This possible protection mechanism might be dependent on the antioxidant activity of CR. In conclusion, pre-treatment with CR at the dose of 25 and 50 mg kg for 7 days can be the beneficial against PRC-induced reproductive toxicity proportionally in a dose-dependent manner.

Cisplatin (CP) treatment causes the damage in male reproductive system. Carvacrol (CARV) is an antioxidant that is naturally found in some plants. We aimed to investigate the effect of CARV on CP-induced reproductive toxicity in male rats. Eighteen adult male Sprague-Dawley rats were used. The control group (n = 6) was treated orally with physiological saline (PS) daily for 14 days and a single intraperitoneal (IP) PS injection on day 10. The CP group (n = 6) was administered with daily oral PS for 14 days and a single IP injection of 10 mg/kg CP on day 10. The CARV + CP group (n = 6) was treated with daily 75 mg/kg oral CARV for 14 days and a single IP injection of 10 mg/kg CP on day 10. CP treatment caused the damage on some spermatological parameters (motility, live sperm rate, and abnormal sperm rate), increased the oxidative stress, and induced testicular degeneration and apoptosis. However, CARV treatment mitigates CP-induced reproductive toxicity.
