Breast development , also known as mammogenesis , is a complex biological process in primates that takes place throughout a female's life. It occurs across several phases, including prenatal development , puberty , and pregnancy. At menopause , breast development ceases and the breasts atrophy. At puberty , gonadotropin-releasing hormone GnRH begins to be secreted, in a pulsatile manner, from the hypothalamus. During pregnancy , pronounced breast growth and maturation occurs in preparation of lactation and breastfeeding. In contrast to the female-associated sex hormones, estrogen and progesterone, the male-associated sex hormones, the androgens , such as testosterone and dihydrotestosterone DHT , powerfully suppress the action of estrogen in the breasts. Calcitriol , the hormonally active form of vitamin D , acting through the vitamin D receptor VDR , has, like the androgens, been reported to be a negative regulator of mammary gland development in mice, for instance, during puberty. Upon parturition childbirth , estrogen and progesterone rapidly drop to very low levels, with progesterone levels being undetectable.
