Estrogen comprises a group of three steroidal hormones: estrone, estriol and estradiol. These hormones are produced naturally in a woman's body by her ovaries, adrenal glands, fat cells and, to a lesser extent, muscle cells. Throughout a woman's lifetime, her natural estrogen levels experience periods of waxing and waning through puberty, pregnancy and menopause.Estrogen contributes to the development of breasts during puberty and pregnancy, along with another type of hormone known as progesterone. Together, they send signals to the body that lead to maturation of breast tissues, ducts and glands.

Estrogen also plays numerous other roles in the female body that affect the uterus, menstrual cycle, bones, muscles and some aspects of the liver and brain. Men produce small amounts of estrogen, too, but it does not play a role in developing secondary sexual traits in them as it does in women.

Estrogen is a hormone that signals the cells in your breast tissue to swell and enlarge, giving the breast its half-circle shape. Fat is deposited there too because estrogen tells it to go there, thus adding to the breast's shape. Atapose tissue is in your breasts and hips, so when estrogen levels rise, those areas respond by 'filling out'.

How to Increase Estrogen Level Naturally

Maintain a healthy diet. Avoid foods high in sugars and carbohydrates. Eating additional lean protein, and foods low in fat and high in fiber, can increase your estrogen levels.

Go for foods that are high in phytoestrogens, which are naturally-occurring substances found in plants that can imitate the function of estrogen in the body. For foods that are rich in phytoestrogens, eat

o Legumes, and especially soybeans, because they contain isoflavonoids, a type of phytoestrogen.

o Bran, beans, fruits and vegetables, because they contain lignans, another type of phytoestrogen.

o Peas, pinto and lima beans, because they contain coumestan, another type of phytoestrogen.

Be careful, however, about excessive consumption of estrogen-rich foods. Too much phytoestrogen consumption may cause tissue growth, making it unsafe for women who have previously had breast cancer.

Your endocrine system requires a healthy body in order to work properly and produce normal levels of estrogen. Eat a wide variety of fresh, organic foods to give your system the best chance to naturally produce estrogen.

Exercise, but not fanatically. Excessive exercise has been linked to a drop in estrogen levels, although regular exercise has also been linked to drops in estrogen levels as well. The difference is while normal exercise is healthy — and might decrease the risk of breast cancer in women and overall longevity — excessive exercise may not be. The increase of estrogen levels due to reduction is exercise is simply not worth it.

Athletes may experience a drop in estrogen levels. This is because women with low levels of body fat have more trouble producing estrogen. If you are an athlete or have very low body fat levels, see your doctor for an appropriate response to replenishing your estrogen.

Before puberty, the male and female breasts are the same. The production of estrogen during the adolescent years triggers the growth of female breast tissue. Estrogen increases fat in the breast, plus milk lobes and ducts, which all add to the size of the breasts. It is necessary to understand this important role of estrogen, because how to get bigger breasts naturally and safely relies upon this biological mechanism.
