Influence of non-alcoholic fatty liver disease on reproductive function in an experiment

BACKGROUND: Currently, the attention of specialists is drawn to the relationship between non-alcoholic fatty liver disease and the development of reproductive disorders in both men and women. To better understand the etiology of these conditions and the mechanisms of pathogenesis, experimental models are being developed. A model using a hypercaloric diet containing increased amounts of carbohydrates is presented in this study. AIM: The aim of this study is to study the effect of non-alcoholic fatty liver disease on the reproductive function of female Wistar rats. MATERIALS AND METHODS: The study was conducted on 30 female Wistar rats, which were divided into two groups. The rats in the control group received standard nutrition. The non-alcoholic fatty liver disease model was reproduced in rats of the experimental group. To verify the diagnosis in the groups, changes in animal body weight, total cholesterol, triglycerides and glucose were assessed. After the diagnosis of non-alcoholic fatty liver disease was established, males were placed with the females to assess the females’ fertility. RESULTS: Keeping animals on a high-carbohydrate diet led to obesity in the females of the experimental group. In rats with non-alcoholic fatty liver disease, a significant increase in the blood levels of total cholesterol and triglycerides, as well as glucose, was found. A significant decrease in the number of pregnancies was recorded in the group with non-alcoholic fatty liver disease. A decrease in the number of individuals in the offspring was also revealed. CONCLUSIONS: The results of the experiment indicate that the use of a hypercaloric diet in rats causes the development of non-alcoholic fatty liver disease. Non-alcoholic fatty liver disease significantly reduces the fertility of female laboratory rats and reduces the number of individuals in the litter. This model can be used to study the causes of the development of the disease, as well as to better understand the mechanisms underlying reproductive dysfunction in patients.
