  • Title: [Rôle of the hypophysis in the endocrine function of the ovary in the duck embryo (author's transl)].
    Author: Weniger JP, Akram H, Reichhart D, Zeis A.
    Journal: Arch Anat Histol Embryol; 1974; 57(2):283-8. PubMed ID: 4620140.
    Abstract:
    Ovaries from normal and hypophysectomized 16-day-old duck embryos were cultured in vitro using 14C-sodium acetate as a precursor and the synthesis level of both 14C-labelled oestrone and oestradiol was determined in each case. The results demonstrate that the synthesis of oestradiol is under hypophyseal control as early as 16 days of incubation, while oestrone synthesis seems not yet to be dependent on pituitary LH at this same age.
