ABSTRACT

Due to the recent data of European Society of Human Reproduction and Embryology (ESHRE), about 1 million of couples are suffering from sterility in Ukraine, and that is 15-17 %. In the structure of causes of this pathology, 30% falls to the male factor, and this percentage is increasing. The disorders of reproductive function occur very often due to hemodynamic disorders which are considered to be one of the most common pathogenic factors in male infertility development. The experiments have been carried out on 78 non-linear white female rats. All the animals were divided into four groups: one control group and three experimental ones. At early stages of the experiment by the histological examination of the organ the moderate swelling of the interstitial tissue, which was unevenly distributed among sinuous canaliculi, was observed. Later, the disclosed changes continued to grow, and at the same time the number of the canaliculi in the line of vision was decreasing. In some sinuous seminal tubules the scaling of the spermatogenous epithelium from its own membrane was observed. On the 14th day of the experiment during the performance of the histological examination from the side of the vascular channel the moderate arterial plethora was observed only locally. The arteries had an ordinary look, their inner elastic membranes were mainly smooth. Sex cells were not rejected from the supporting ones, their layer could have been distinguished. In the lumen of the canaliculi there were matured spermatozoa.
