The primary breast enhancement hormone is estrogen. Estrogen is a hormone that is naturally produced in the two ovaries. This hormone is responsible for helping to maintain the reproductive cycle as well as the secondary sex characteristics of girls at puberty. A number of hormones really start to become active around the time of puberty, and estrogen is only one of the ones responsible for growth of breast tissue.
Some naturally occurring herbs also have chemical properties that are similar to estrogen. These chemicals, or phytoestrogens, seem to do some of the same things in the body that estrogen does. Phytoestrogens are found in fennel, fenugreek, wild yam, dandelion root, and saw palmetto. When added together, the estrogen like effects of these phytoestrogens have been noted in some herbal breast enhancing creams and pills to increase breast size.
The same phenomenon is noted during the menstrual cycle. Estrogen levels are at their highest during the week right before a woman begins to menstruate. This causes an increase in sensitivity in the breasts that may be noticed as soreness in some women. Many women also notice that their breasts swell a bit around this same time. This is the work of the breast enhancement hormone, estrogen.
Breast growth is at its highest during puberty and does not continue throughout a woman's life without a little help from phytoestrogens and implants. Both of these can improve the size and firmness of breasts either by supplementation or surgery. The effects of supplementation will only be temporary, but surgical implants can add several sizes to a woman's breasts permanently.
When discussing a breast enhancement hormone, many women just assume that hormone therapy is the only method to increasing bust size. This could not be further from the truth. Hormone therapy is only one way to increase breast size, and many times hormone therapy has been implicated in many cancers. When doing research, you may be able to find other phytoestrogen herbs that will work better for you. Herbal remedies can be used as a synthetic breast enhancement hormone when consulting first with your physician.
