Endocrine System in Embryogenesis

New experimental methods that made it possible to perform surgical operations on embryos, extirpation of endocrine glands with their subsequent implantation, destruction of endocrine glands by ionizing radiation, blocking of one or another gland by chemical means, introduction of hormones, transplantation of gland rudiments, made it possible to clarify some of the established issues of endocrinology of the antenatal period of development. The results obtained gave grounds to talk about endocrinopathies of intrauterine development. During these periods, the processes of development, formation, differentiation occur with particular intensity, and violation of morphogenesis, maturation of endocrine glands have significant disturbances in the fetus.
