    [Reprinted from The American Practitioner, November, 1914] ACTION OF CORPUS LUTEUM UPON THE MAMMARY GLANDS BY ISAAC OTT, M.D., Professor of Physiology, AND JOHN C. SCOTT, M.D., Lecturer on Physiology, Medico-Chirurgical College of Philadelphia. All workers agree as to the presence of a hor- mone increasing the size of the mammary glands for Lane-Claypon and Starling it is in the foetus, for Foil, Biedel and Koenigstein it is also in the foetus; Bouchacourt, Lederer and Prizbram and Basch, it is in the placenta; Ancel, Bouin, O’Donoghue and others, it is in the corpora lutea. Ott and Scott1 were the first to show that injec- tions of an extract of corpora lutea and certain other extracts increase the secretion of milk to a marked degree. Mammary gland enlargement and the quantity of milk secreted should stand in direct relation. But in virgin animals the breasts do not contain milk, and the effect of the internal secretions upon their mammary hypertrophy is yet to be determined.
