The breasts are not a part of the woman's genitals. They develop as a result of the action of the sexual hormones that manifest in puberty.

However, this does not mean that they do not take part in the erotic life of the woman, through their important psychological role.

The breasts are first of all important for breast-feeding the baby, apart from the usual erotic pleasure.

THE CONSTITUTION OF THE BREASTS
The mammal gland is usually "in pause", except for the interval of pregnancy and breast-feeding. The main constituents of the breast are the conjunctive tissue, rich in elastic fibers and the adipose tissue, rich in fat.

Each breast has 15 to 20 sections, called lobes that are arranged like the petals of a daisy. Each lobe has many smaller lobules, which end in dozens of tiny bulbs that can produce milk.

The lobes, lobules, and bulbs are all linked by thin tubes called ducts. These ducts lead to the nipple in the center of a dark area of skin called the areola. Fat fills the spaces between lobules and ducts.

There are no muscles in the breast, but muscles lie under each breast and cover the ribs.

Each breast also contains blood vessels and vessels that carry lymph. The lymph vessels lead to small bean-shaped organs called lymph nodes, clusters of which are found under the arm, above the collarbone, and in the chest, as well as in many other parts of the body.

ANATOMY AND PHYSIOLOGY
Each of these accessory reproductive glands lies on the superior surface of the chest wall lying mostly on top of the pectoral's muscle.

During pregnancy the alveoli enlarge and during lactation the cells secrete milk substances, i.e. proteins and lipids. The cells surrounding the alveoli contract to express the milk during lactation.

Breast tissue is supported by ligaments called Coopers ligaments that keep the breasts in their characteristic shape and position. In the case of older women or in pregnancy these ligaments become loose or stretched, respectively, and the breasts sag.

Reproductive hormones are important in the development of the breast in puberty and in lactation. Estrogen promotes the growth of the gland and ducts while progesterone stimulates the development of milk producing cells.

Prolactin, released from the anterior pituitary gland, stimulates milk production. Oxytocin, released from the posterior pituitary in response to suckling, causes milk ejection from the lactating breast.

In response to hormone stimulation, the breasts enlarge due to the growth of ductal and alveolar tissues and an increase in fat deposits. The nipple and areola also enlarge and become more sensitive to touch.

When the woman begins to menstruate, the breasts undergo a periodic premenstrual phase that varies with the individual but can include an increase in size, swelling and tenderness.

The symptoms subside within a few days of the onset of bleeding. During pregnancy, the breasts increase in size dramatically due to the influence of progesterone.

The nipple and areola become deeply pigmented and increase in size. The necessary machinery to produce milk by late pregnancy replaces most of the fat. After delivery the breasts begin to secrete milk.

The gland rapidly returns to the pre-pregnant state when nursing ceases. The postmenopausal breast may retain its shape but the milk producing machinery is mostly replaced by fat.

Nonetheless, the mammal gland gets its definitive structure only during pregnancy.

WHY DO BREASTS HAVE DIFFERENT SHAPES?
If the mammal glands develop in a plan parallel with the ribs, the breast will be somewhat flat. If they develop on a perpendicular plan, the breast will be hemispherical. Of course, the intermediary situations all exist, and consequently the variety of forms is infinite.

WHY DO NOT ALL BREASTS HAVE THE SAME CONSISTENCY?
If the conjunctive tissue is predominant over the fat tissue, the breast will be firm; if, on the contrary the fat tissue is predominant over the conjunctive tissue, the breast will be less firm. Again, infinity of forms is possible.

WHY IS ONE BREAST MORE DEVELOPED THAN THE OTHER?
The halves of our body are not identical, nor symmetrical. This is valid in the case of the breasts as well, as any two given organs of the body are very seldom identical.

99.9% of women's breasts are not symmetrical. The breasts will have different volumes of different components - more tissue, less fat, larger lobules, more connective tissue - it happens.

The nipples may be smaller, perpetually erect, inverted, or very prominent. The areolae complex may be large, small, non-existent, one larger than the other, be bumpy, have hair growth, be augmented due to herniated tissue/fat - sometimes called "snoopy".

WHY DO NOT ALL BREASTS HAVE THE SAME SIZE?
Breast size can vary from person to person although several deciding factors are usually the amount of breast tissue, body fat percentage, heredity and if you have been pregnant.

WHAT IS AN INVERTED NIPPLE?
Such a nipple is withdrawn towards the interior of the body, instead of being prominent in the exterior. In other words, it resembles to a navel. This particularity is congenital, meaning that it comes from birth.

Such a nipple is an impediment for breast-feeding, but fortunately a simple surgical intervention may solve this problem.

CAN I DEPILATE THE HAIR ON THE BREASTS?
Any woman may have several hairs around her areola, where there are sebaceous glands. In this case, their removal is not dangerous. However, if this hair is on the areola, whose tissue is very sensitive, it is best if you shave it every day, so that depilating it will not cause infections.

IS THE SUN DANGEROUS FOR THE BREASTS?
It appears that the sun does not cause breast cancer. Nonetheless, we recommend limited exposure to the sunlight, due to the harmful effects it may have on the sensitive skin of the breasts. The sun has serious effects on the elastic fibers and speeds their aging.
Therefore, before exposing your breasts to the sun rub some sunscreen lotion on them.

IS THE BREASTS' VOLUME SUBJECT TO VARIATIONS?
Yes, it is. If you gain weight, the volume of the breasts will increase as well, because the adipose tissue increases.

If you lose weight, the breasts in which the adipose tissue is predominant will become smaller, while those with conjunctive predominant tissue will suffer few changes.

The best is to avoid variations in weight, as they damage the elastic fiber of the skin, which tend to become loose.

Also, after your breasts enlarge due to pregnancy they usually shrink postpartumly, called involution. Other changes result from having breastfed, estrogen and progesterone supplementation in the form or shots, implants or medications, hormonal disorders, menopause and lastly age.

As you age your skin thins, you lose breast volume due to the shrinking of your lobules due to a decrease in hormones. But don't be afraid, there is a very natural way to keep the youth of your breasts: LOVEMAKING WITH SEXUAL CONTINENCE .
