Summary: | Studies on the effects of exogenous hormones have led to the accumulation of a considerable body of information on the reproductive physiology and endocrinology of birds, and of the female domestic fowl in particular. Exogenous estrogens have been shown to produce striking effects in immature pullets, both on the morphology of the secondary sex organs and on the composition of the blood and other tissues. The similarity of these changes to those which occur in the normal pullet at puberty clearly indicate the presence of an endogenous estrogen or estrogens in the bird, and crude extracts of the ovaries of hens have been shown to have estrogenic activity by bioassay in rats. |
