Abstract

ABSTRACT Introduction: Negative demographic trends are often associated with high levels of infertility, including male. In the modern literature there are data on morphofunctional changes in various organs and tissues during inflammation of various origins, obtained in experiments on animals. At the same time, there are practically no studies on changes in the seminal glands in inflammation of different etiologies. The aim of this study is to identify the morphofunctional features of the seminal glands in the dynamics of acute infectious (staphylococcal) inflammation in rats. Materials and methods: Experimental studies were performed on 40 nonlinear male rats weighing 180-200 g. Microscopic and histochemical studies were performed on the 7th, 14th, and 28th day. Results: On the 7th day of staphylococcal inflammation, morphofunctional changes in the seminal glands were detected in rats in the form of a moderate rearrangement of the spermatogenic epithelium, which was manifested by a decrease in Sertoli cells and the number of type A light spermatogonia along with an increase in the number of type A dark spermatogonia and type B spermatogonia. The described changes were accompanied by a decrease in the metabolism of nucleoproteins in epithelial cells. On the 14th day, the morphological changes were characterized by a sharp decrease in Sertoli cells, the absence of type A light spermatogonia and an increase in the number of type A dark spermatogonia and type B spermatogonia. After 28 days, there is an increase in the number of tubules with the presence of type A light and dark spermatogonia, as well as single Sertoli cells, which indicates the restoration of the morphofunctional state of the seminal glands. Conclusions: More pronounced compensatory-adaptive processes in the seminal glands occur within a period of 28 days from the start of modeling of staphylococcal inflammation. The latter is confirmed by the appearance of various shapes and sizes of tubules with restored spermatogenic epithelium of various stages of development. The presence of type A light and dark spermatogonia indicates the reserve capacity of the seminal glands.
