This research work touches upon an important problem in the field of reproductive health and the influence of the environment on the formation of the endocrine system of offspring. The main purpose of this study was to study the effect of pesticides on the growth and formation of the adrenal cortex in offspring through the mother's body during pregnancy. To achieve the goal of the study, animal experiments were conducted in which various doses of pesticides were administered to mothers in utero. After the birth of the offspring, the researchers analyzed the structure and function of the adrenal cortex. The results obtained indicate significant changes in the structure of the adrenal cortex in offspring exposed to pesticides in utero. These changes can have a negative impact on the hormonal balance and metabolic processes in the offspring, as well as have long-term consequences on the health of the adult body. The results obtained are important for understanding the influence of the environment on the development of the endocrine system in the offspring and can serve as a basis for developing measures to protect pregnant women and their offspring from the adverse effects of pesticides during pregnancy.
