[Interactions of male sex, thyrotropic and chorionic gonadotropic hormones in ontogenesis].
The influence of thyrotropin and chorionic gonadotropin on the testicles and of testosterone and its 5 alpha-reduced metabolites upon the thyroid was studied in ontogenesis of rats and rabbits. It was determined that thyrotropin and gonadotropin stimulate the testicle development, exhibiting different effects on their structures. Thyrotropin has a direct action upon the testicles and does not affect the thyroid, that was proved by thyroidectomy. This effect is manifested already in the prenatal period of the development. Testosterone and its metabolites exert a direct action on thyroid function, their effects on the organ being different.
