Purpose: Chronic stress represents a critical influence on ageing of Leydig cells in testis. We aimed to investigate expression changes of microRNA (miRNA) associated with stress-induced ageing in Leydig cells. Methods: Brown Norway rats were separated into three groups, young control group, stress group and age group. Physiological changes, including serum corticosterone and testosterone level...
