Abstract
IN further investigations on the œstrogenic hormone, which to a large extent is excreted in the urine of the stallion1, we have examined the influence of this hormone on the secondary sexual characteristics, especially on the mammary gland. By the use of follicular hormone, Laqueur was able to induce lactation of male guinea pigs. We have now observed the same effect with the hormone obtained from the urine of the stallion and in the actual cases the lactation of the male animals has continued for 21 days.
