ABSTRACT
We studied the expression of insulin-like growth factor 1 (IGF-1), androgen receptor (AR) and luteinizing hormone receptor (LHR) in the ovaries under the conditions of the modeling and subsequent treatment of functional ovarian cysts with gonadotropin-releasing hormone antagonist (ant-GnRH). The intensity of IGF-1, LHR, and AR expression in the generative elements of rat ovaries changed under conditions of functional ovarian cysts simulation, as well as during treatment with ant-GnRH. In both experimental groups, the expression levels of the studied markers in preantral follicles and epithelial lining of cysts were found to be related to the number of growing follicles and cysts. A divergence of LHR and AR expression indices and a more pronounced decrease in the number of cystic cavities were observed in the group receiving ant-GnRH. These changes demonstrate a positive effect of ant-GnRH on intra-ovarian regulatory factors and a therapeutic effect in functional ovarian cysts.

The morphofunctional features of the ovaries were evaluated in rats with functional ovarian cysts model treated with gonadotropin-releasing hormone antagonist. Administration of the antagonist significantly (p=0.009) reduced the number of cysts and the growth of follicles in the ovaries. The obtained results attest to a possibility of successful treatment of functional ovarian cysts with gonadotropin-releasing hormone antagonist.
