Hormone Treatments for Breast Growth

Breast tissue is sensitive to hormonal changes. Hormonal changes can cause an increase in size, tenderness and breast composition. These changes occur during every menstrual cycle. The introduction of hormones might change breast size, but it can also cause many unwanted and unpleasant side effects.

Progesterone is a female reproductive hormone present in a woman's body during a menstrual cycle, and it rises during pregnancy. Progestin is a synthetic hormone of similar composition to progesterone that is used as an oral contraceptive. Both of these hormones can induce breast growth. These hormones increase the amount of glandular tissue in the breast. Progestin should not be used without consulting your physician.

Growth Hormones

Human growth hormones are produced naturally and can be synthetic. These hormones can also increase the size of your breasts, but they are not recommended to be used for this purpose. The unnecessary use of growth hormones can result in serious and possibly life-threatening complications. Growth hormones should only be used under a doctor's supervision.


Estrogen is a female reproductive hormone used to increase breast tissue in transgender women. This treatment will not be effective for cisgender women. Estrogen is administered to men to bring their level of estrogen to that of a woman. This treatment can cause serious health problems, such as tumors, heart attacks and blood clots.
