Abstract
PURPOSE
Fibrates are drugs widely used for the treatment of hyperlipidemic disorders. Previous studies on a novel analogue of clofibrate, called silafibrate, have shown good lipid lowering effects. This study was designed to assess the role of silafibrate as a peroxisome proliferator-activated receptors (PPARs) agonist on sperm health and spermatogenesis in adult male rats.
MATERIAL AND METHODS
Seventy male Wistar rats were randomly allocated into 7 groups: Cl-10, Cl-20, and Cl-40 mg/kg/day (clofibrate); Si-10, Si-20, and Si-40 mg/kg/day (silafibrate); and C, control. After a 28-day treatment, all rats were euthanized. Blood samples were taken for determination of testosterone, total antioxidant capacity, levels of malondialdehyde, and oxidized low-density lipoprotein. Reproductive organs were dissected and spermatozoa collected from the epididymis for analysis.
RESULT
Sperm parameters (count, motility, viability, and morphology) and total serum testosterone decreased significantly in clofibrate-treated (20 and 40 mg/kg) rats (P < 0.05) as compared with normal rats.
CONCLUSION
We conclude that PPARs agonists have significant adverse effect on sperm viability, motility, and total serum testosterone, and could be harmful for sperm parameters and male reproductive function in rats.
