The ontogenesis of reproductive hormones in the female embryo of the domestic fowl

The ontogenesis of sexual hormones and the responsiveness of both ovaries to LH were studied during the last third of incubation of chick embryos. Pituitary LH and FSH and serum 17β-estradiol increase through development to reach a plateau near hatching. Serum LH and the ovarian progesterone content...
