[Hormonal regulation of human mammary function].

This review summarises our present knowledge on the endocrine aspects of human mammary function. The fact is stressed that much of the knowledge on mammary function is based on animal studies, and therefore caution must be exercised in drawing conclusions as to mammary function in humans from such experiments. Some recent aspects of mammary function especially in humans are also summarised, as evaluated through 2-bromo-alpha-ergocryptine (CB 154). Special emphasis is placed upon the role of prolactin in the initiation and maintenance of human lactation, some phylogenetic aspects of this hormone are also discussed.
