Abstract
The molecular mechanisms controlling the onset of copious milk secretion are only now beginning to be elucidated. We have known for nearly four decades that progesterone suppresses milk secretion during pregnancy, and that the fall in progesterone near parturition is necessary for secretory activation. Similarly, we’ve known for 15 years that transforming growth factor β (TGFβ) also suppresses milk secretion. Yet no formal link between the two has ever been established. This work aims to review the evidence for and against a link between progesterone and TGFβ, raise unanswered questions, and to propose further lines of research.
