What is the development of mammary glands?
Mammary gland function is regulated by hormones. At puberty, increasing levels of estrogen stimulate the development of glandular tissue in the female breast. Estrogen also causes the breast to increase in size through the accumulation of adipose tissue. Progesterone stimulates the development of the duct system.
Which hormone brings about development of mammary gland?
The ovarian hormone, estrogen, is another critical regulator of pubertal mammary development and is responsible for the tremendous surge in growth occurring during this period that generates a functional mammary gland (Fig. 4).
What controls the growth and development of mammary glands?
