Structural and morphological changes of endometrium related to ovary cycle and condition of genital function of cows

The article analyses structural and morphological changes of endometrium related to ovary cycle and condition of genital function of cows. It has been determined that during estrus, we find high functional activity, activation of physiological secretion processes, intensification of protein lipid metabolism. Endometrium of proesrtrus shows activation of regenerative processes accompanied with development of connective endometrium matrix. Such condition characterized by accumulation glycosaminglycans and increase the reactive activity of acid proteinglycans of deep phase of fibrous matrix proteins. Endometrium of cows during metestrus is charachterized by simultaneous dystrophic degenerative changes caused by hormone-dependent cell desquamation, and cell proliferation initiation. In postmorbid condition endometrium shows differentiation of stroma cells, vessel territories and uterine glands, reduction of proliferation processes, depression of regenerative ability and neoangenogenesis.
