Repeatedly heated palm olein disrupts male reproductive system of rat: A histological and biochemical study

The aim of this study was to investigate the effect of heated and unheated palm olein in different doses on the male reproductive system of rats. Forty male rats were randomly classified into five groups (n = 8) including Control, Low palm, High palm, Heated low palm and Heated high palm. The palm olein was administrated orally for 6 months. Histological and biochemical parameters of the male reproductive system were measured. There was a significant reduction in sexual hormones, serum levels of superoxide dismutase, high‐density lipoprotein, testis weight and sperm parameters in the high dose and heated palm olein groups compared to the other group (p
