title: [Development of the breasts of the fetus. Effects of the administration of hormonal preparations during pregnancy].
abstract: The mammary glands of ten still-birth premature fetuses were studied histologically. In seven cases a combination of oestrogen-progesterone preparations were administered to the mother in early pregnancy for a duration of at least 3 months. In three cases no hormones were administered. According to our observations and the experimental work of other investigators, we may conclude that oestrogenic hormones inhibit the development of the mammary gland.
