Objectives: To determine how the diet of mothers and offspring affects the morphological characteristics of ovaries, subcutaneous and perigonadal adipose tissue. Study design: Ten female Sprague Dawlaey rats were divided into two groups. One group fed standard laboratory food and the other group fed food rich in saturated fatty acids. All rats were then mated with the same male. After pregnancy and lactation, female offspring of both groups of mothers were divided into two groups, so that one group was fed standard laboratory food and the other food rich in saturated fatty acids for 22 weeks. Material and methods: Rats were sacrificed, and their ovaries were weighed, subcutaneous and perigonadal adipose tissue were isolated. The presence of cystic formations, the percentage of collagen in the ovarian stroma was determined in the ovaries, and after immunohistochemical staining, the number of macrophages and the intensity of immunohistochemical staining for TNF-α in ovarian tissue were determined. Histomorphometry was performed on histological sections of subcutaneous and perigonadal adipose tissue in the software Cell Profiler 4.2.1. to determine the surface area and number of adipocytes. Results: Ovarian weight was higher in the offspring of the mothers fed food rich in saturated fatty acids. The same groups also showed the occurrence of cystic formations and a higher percentage of collagen in the ovaries. The number of CD68 positive cells and the intensity of the immunohistochemical signal of TNF - α were more influenced by the diet of the offspring, so a higher number of macrophages and a stronger intensity of immunohistochemical staining for TNF - α was demonstrated in offspring fed food rich in saturated fatty acids. No statistically significant differences in adipocyte size were found between the groups. The offspring of mothers fed standard laboratory food had a significantly higher number of small - area adipocytes in the subcutaneous adipose tissue. Conclusion: Maternal nutrition affects ovarian weight, the incidence of cystic formations in the ovaries and ovarian fibrosis. The mother's diet affects the adipocyte surface area in subcutaneous adipose tissue. The diet of the offspring affects the number of macrophages and the intensity of the immunohistochemical signal TNF - α.
