[Dynamics of morphologic changes in the ovaries of guinea pigs modified by implanted endometrium].

The implantation of section of cornual endometrium into ovaries of guinea pigs was carried out. The purpose of the work is to evaluate the dynamics of morphologic changes occurring in ovaries following implantation of endometrium. During a 40-weeks period of followup, it was stated that after the initial massive degeneration of the normal endometrium, implanted into the ovaries, the regenerative processes of basic elements in endometrium take place, involving the excessive proliferation of its elements, and resulting afterwards in lesion of gonads. The morphologic manifestations in ovary consist principally in proliferation of glandular tubes, formation of endometrial cysts of various size, in growth of connective tissue, and progressive loss of vesicles in ovary. Presented morphologic dynamics may be a suitable experimental model for further studies on endometriosis in ovary.
