Effect of Sodium Cyanide-induced Tissue Hypoxia on Reproductive Capability of Male Mice and the Protective Effect of Ethyl Pyruvate

The present study aimed to assess the effect of tissue hypoxia induced by sodium cyanide (NaCN) on male mice fertility and the protective role of ethyl pyruvate (EP). A number of 30 adult mice were assigned to three groups: 1) a control group, 2) a treatment group treated with 2 mg/kg of NaCN, and 3) a treatment group treated with 2 mg/kg of NaCN, along with 40 mg/kg EP (NaCN+EP). After 35 days, animals were anesthetized and serum, sperm, and tissue samples were taken. The results demonstrated a significant decrease in sperm quality, reproduction potency, and anti-oxidant potential, as well as an increase in lipid peroxidation in the NaCN group (p <0.05). Moreover, the use of EP effectively restrained the disastrous effects of tissue hypoxia. It can be concluded that EP can moderate the complications resulting from tissue-hypoxia that is related to testes parameters.
