Abstract

The investigations showed that differentiation and functional activity of gonadotropocytes in ducks at different phases of a sexual cycle change in complete conformity with the quantitative changes of gonadotropic hormones in the hypophysis and peripheral blood. Intensification of the function of gonadotropocytes and an increase in the content of gonadotropins in blood and hypophysis correspond to activation of gonads. The refracteriness of gonads is accompanied by involution of gonadotropocytes and inhibition of synthesis and secretion of gonadotropins in them.
