THE EFFECT OF ALOE VERA HYDROALCOHOLIC EXTRACT ON SPERMATOGENESIS PARAMETERS AND HISTOLOGICAL CHANGES IN THE TESTIS OF RATS FED WITH A HIGH-FAT DIET

Diseases caused by high-fat diets and obesity are now recognized as a health problem. The aim of this study was to evaluate effect of aloe Vera hydroalcoholic extract on spermatogenesis parameters and tissue structure of testis of rats fed with a high-fat diet.

40 adult male Wistar rats were randomly divided into 5 groups (control group (Con), control group fed with a high-fat diet (HFD), and experimental groups 1 to 3 (HFD +150 mg aloe Vera, HFD +300 mg aloe Vera, and HFD + 600 mg aloe Vera(. High-fat emulsion and three doses of aloe Vera were administered orally for 60 days. Finally, after dissection and preparation, testicular tissue was examined histopathologically. The number of spermatogonia, spermatocytes, spermatids, Sertoli, and Leydig cells was counted. Data were analyzed by SPSS software and the means were compared using ANOVA and Post hoc Tukey's test at 0.05%.

The results showed a significant decrease in mean of spermatogonia, spermatocytes, spermatids, and Leydig cells in the group receiving a high-fat diet (HFD) compared to the control group. Aloe Vera extract significantly increased the number of sex cells in the testis. Increasing the dose of aloe Vera to 600 mg/kg further improved histopathological tissue damage.

The results of study showed that the hydroalcoholic extract of aloe Vera in mice fed with a high-fat diet significantly reduces the risk of pathological tissue damage in testes and increases fertility by increasing the number of sex cells.
