Transformation of endometrial cells and mammary gland cells occurs under the influence of altered ratios of hormones of the pituitary-ovarian system, which leads to changes in the morphological structure of these organs. Hyperplastic processes in the endometrium are one of the causes of infertility in women of childbearing age, which makes it important to study this problem. Purpose: to determine the level of ovarian and pituitary hormones in the blood plasma of women of reproductive age under conditions of development in the body of various types of endometrial hyperplasia and benign breast tumors. Object and methods of research. Surveys of women of reproductive age were conducted, which were divided into: the comparison group – women with GPE, and the main group – women with GPE and benign diseases of the breast. The analysis of indicators was performed taking into account the type of endometrial hyperplasia – GPE without atypia, atypical GPE and endometrial polyps. The condition of the pituitary-ovarian system was assessed by determining the hormones of the reproductive panel (follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen and progesterone). Levels of pituitary and ovarian hormones were determined using test kits for enzyme-linked immunosorbent assay. Results. It was found that the main endocrine disorder in GPE and proliferative dysplasia of the mammary glands is a hormonal imbalance with a predominance of hyperestrogenism and decreased progesterone levels. The greatest violations occur in atypical endometrial hyperplasia. It is shown that changes in pituitary hormones in GPE are manifested by an increase in plasma of both FSH and LH. Along with this, there is a decrease in the ratio of LH / FSH, which indicates the predominance of FSH products. Conclusions. In women with GPE and benign neoplasms of the mammary glands, there is an imbalance of hormones of the pituitary-ovarian system, which is expressed by relative hyperestrogenism, progesterone deficiency, elevated levels of FSH and LH, but a decrease in the ratio of LH / FSH. These changes are exacerbated in patients with atypical endometrial hyperplasia.
