The Hormonal Basis for "Witches'Milk."

Abstract

Mammotropin was detected in the urine of 4 newborn babies. One of the babies, a boy, lactated, and his urine showed the largest amount of hormone (1 unit in 0.5 cc). It is suggested that “witches' milk” is formed in the infantile breast after successive stimulation with oestrin and mammotropin.
