During pregnancy, the mammary gland undergoes significant growth and development primarily due to the influence of progesterone. Progesterone is a hormone produced by the ovaries during pregnancy and plays a crucial role in preparing the mammary gland for lactation.Progesterone acts on the mammary gland to stimulate the growth and branching of the ductal system, which is responsible for transporting milk from the alveoli to the nipple.
