The breasts are hormonally regulated tissues that respond to a number of hormones circulating within the body. The developmental cycle of the breasts begins in puberty, and extends to changes during pregnancy. During puberty, the breasts undergo periods of cell proliferation and division, which causes the breasts to enlarge and develop. During pregnancy, the cells of the breast proliferate to enlarge the breast, then transform into specialized cell types that make and secrete milk to allow for breastfeeding. After breastfeeding stops, the breast cells die and the breast reduces to its size to pre-pregnancy. Four hormones control the majority of these behaviors.

Boy, 16, was given estrogen at L.A. juvenile hall, suit says - Los Angeles Times
A year-old boy being held at a Los Angeles County juvenile hall developed enlarged breasts after he was prescribed estrogen to treat a behavioral disorder, a move that baffled doctors who said the treatment defied medical logic, according to a lawsuit filed last month. The teen, whose identity is being withheld because of his age, was diagnosed with oppositional defiant disorder, or ODD, two days after he was arrested and housed at Eastlake Juvenile Hall in June , the lawsuit said. Estrogen regulates the development of female sexual characteristics and reproduction. Men produce the hormone at much lower levels. After taking approximately 13 daily doses of the hormone, the teen was diagnosed with gynecomastia, defined as the enlargement or swelling of breast tissue in males whose estrogen level is too high, medical records show.

There are three major endogenous estrogens that have estrogenic hormonal activity: estrone E1 , estradiol E2 , and estriol E3. Estradiol, an estrane , is the most potent and prevalent.
