Breast Development

Though breast growth is not able to be seen until puberty, breast development begins very early in the embryo and can be discern within just a few weeks of conception. Interestingly, the earliest stages are indistinguishable in male and female fetuses, so many men could develop fully implementation breasts given the right hormonal circumstances

After birth the breast has only two phases of expansion; the first at puberty with the outpouring of the hormones oestrogen and progesterone; the second during pregnancy and lactation, when the milk-producing lobules become larger

If puberty is undersized or if a woman remains childless, her breasts will not fully develop. The first stage of breast development begins in the embryo at about six weeks, with a thicken in the skin called the mammary ridge or milk line

By the time the fetus is six months old, this extends from the armpit to the groin, but it soon dies back, leaving two breast buds on the higher half oft he chest. Occasionally, rudimentary mammary glands enlarge along the milk line forming supplementary nipples or breasts that sometimes keep it up into adult life. More rarely, the two breast buds fade away with the rest of the milk line, so that the nipples are not in attendance from birth

Because the initial progress of the milk line is the same in male and female fetuses, this development can come into sight in the male and the female.

When a female fetus is about six months old, 15 – 20 solid columns of cells produce inward from each breast bud. Each column becomes a divide “sweat” or exocrine gland. With it’s own separate duct important to the nipple

By the eighth month of fetal expansion, these columns of cells have become hollow so that, by birth, a nipple and a rudimentary milk-duct arrangement have formed. No further development takes place until puberty

The first external signs of breast increase appear at the age of 10 or 11 – though it can be as late as 14 years. The ovaries start to secrete estrogen leading to an accumulation of fat in the connective tissue that causes the breast to make bigger. The duct arrangement also begins to develop, but only to the point of form cellular knobs at the end of the ducts.

As far as we know the mechanisms that secrete milk doesn’t develop until pregnancy. Although the breast may come into view fully grown within a few years of puberty, strictly speaking, their development is not complete until they have satisfied their biological function – that is, until the women carry a pregnancy to term and breast-feeds her baby, when they will experience further changes

MATURITY OF THE BREASTS

Once a young woman reaches teenage years, and ovulation and the menstrual cycle begins, the breasts start to mature, forming real secretary glands at the ends of the milk ducts. Initially these glands are very prehistoric and may consist of only one or two layers of cells bounded by a base membrane.

Between this membrane and the glandular cells are cells of another type, called myo-epithelial cells, these cells are the ones that contract and squeeze milk from the gland if pregnancy occurs and milk manufacture takes place.

With additional growth, the lobes of the glands become separated from one another by dense connective tissue and fat deposits. This tissue is with no trouble stretched. This is where the natural enlargement formula comes in and allows the improvement that in general occurs during pregnancy when the glandular rudiments swell and grow

The duct system grows by a long way after conception and many more glands and lobules are shaped. This causes the breast to increase in size as it mature to fulfill its role of as long as food for the baby

FEMALE CHANGES

Most women notice that just before menstruation their breasts enlarge and their nipples become sensitive and even raw. The texture of the breasts alter and they become rather lumpy, with small separate swellings that resemble orange pips in both feel and size. These lumps are glands in the breast which enlarge in grounding for pregnancy.

If pregnancy doesn’t occur, breasts return to their normal size and the glands become hardly noticeable to touch within a few days, ready for re-growth the next month. These changes in the breast are only one part of many change that occur in the female body as the result of the journal ebb and pour of the female hormones estrogen and progesterone

AGING OF THE BREASTS

As we get elder, our breasts tend to sag and flatten; the larger the breasts, the more they sag. With the menopause there is a reduction in motivation by the hormone oestrogen to all tissues of the body, including breast tissue; this results in a reduction in the glandular tissue of the breasts. So they unfastened their earlier fullness.

Regular do exercises would have however prevented or slowed down the elderly process. Much of the connective tissue in the breast is collected of a fibrous protein called collagen, which needs oestrogen to keep it healthy. Without oestrogen, it becomes dried out and inelastic. Once the collagen has lost its shape and stretch ability it “was” believed that it could not return to its previous state or condition

STAGES – BREAST DEVELOPMENT

Human breast tissue begins to expand in the sixth week of fetal life. Breast tissue initially develops the length of the lines of the armpits and extend to the groin (this is called the milk ridge). By the ninth week of fetal life, it regresses (goes back) to the chest area, leaving two breast buds on the upper half of the chest. In females, column of cells grow inward from each breast bud, becoming divide sweat glands with ducts leading to the nipple. Both male and female infants have very small breasts and actually knowledge some nipple discharge throughout the first few days after birth.

Female breasts do not begin increasing until puberty—the period in life when the body undergoes a multiplicity of changes to prepare for duplicate. Puberty more often than not begins for women approximately age 10 or 11. After pubic hair begins to grow, the breasts will set in motion respond to hormonal changes in the body. Specifically, the manufacture of two hormones, estrogen and progesterone, signal the growth of the glandular breast tissue. During this time, fat and rubbery breast tissue becomes more elastic. The breast ducts begin to grow and this enlargement continue until menstruation begins (typically one to two years after breast development has begun). Menstruation prepare the breasts and ovaries for potential pregnancy.
