The whole process of female breast development

The beauty of female breasts occupies a very prominent position in the overall aesthetic system of female body beauty. In today's increasingly open society, many men look at a woman's breasts at first sight, and breasts are also very important for a woman's self-confidence. The expansion of female breasts is also an important prominent feature of the female body and the most obvious feature between men and women. Women's breasts are not this big when they are born. They develop slowly. Let's take a look at how they change at different stages.

The whole process of female breast development:

1. The nipple period in infancy

Before puberty, when the breasts have not yet developed, there are only a pair of small nipples on the breasts.

2. Breast budding during puberty

This is the initial stage towards becoming a mature woman. Menstruation has just begun, the pubic hair around the genitals is gradually sprouting, and the area around the nipples is beginning to swell and grow. In the teenage years, breast size continues to increase slowly as age increases; at this stage, the breasts and surrounding areolae are noticeably bulged, giving the chest a conical shape.

3. Firm breasts in early adulthood

The most ideal stage of human physical condition is at the age of twenty-five, during which time human physical condition reaches its peak and all growth processes are completed. Women in their twenties have breasts that are most similar to hemispherical.

4. Perfect breasts after becoming a mother

Under the combined stimulation of motherhood and the sudden enlargement of breast tissue, the breasts filled with milk swell further and begin to show signs of sagging.

5. Sagging breasts of middle-aged women

As the reproductive stage comes to an end, although the breasts are no longer as plump and large as during the lactation period, they cannot stop the trend of sagging, and now they hang more loosely on the chest.

6. Sagging breasts in old age

After entering old age, tissues throughout the body begin to shrink, and the breasts become flatter. At this time, the breasts still hang loosely on the chest, but the difference is that the wrinkles on the breast skin increase a lot.

The development of the breast can be described using the Tyner's maturity scale.

1. Infancy: The breasts are in a static state. Only the nipples are protruding, and generally there is no difference between boys and girls. In girls, breast development is part of the first stage of Tyner's puberty.

2. Pre-puberty: 10 to 12 years old, before menstruation, the nipples are slightly raised and the color of the nipples and areolas becomes darker. Breast development belongs to the second stage of Tyner's sexual maturity. ? ??

3. Puberty: The onset of menstruation in Chinese girls usually occurs around the age of 14. Under the influence of estrogen secreted by the ovaries, breast development becomes apparent. At this time, active physiological changes occur in the glandular ducts and alveoli, fibrous tissue proliferates and fat is deposited around the breasts, and the breasts gradually become fuller and more raised. Generally, breasts mature at the age of 16 to 18 and stop developing at the age of 22. Stage III: The nipple and areola are further enlarged, and their outer contours are not separated. Stage 4: The areola and nipple rise above the breast to form another hillock. Stage 5: Also the mature stage, only the nipple is protruding, the areola recedes, and the overall contour of the breast is

Changes in breasts at different stages of development:

During the 5th to 6th week of pregnancy, the breasts are affected by large amounts of estrogen and progesterone, the milk ducts and alveoli increase significantly, the nipples and areola become larger, the pigmentation deepens, and the breasts become fuller. By mid-pregnancy, dilated superficial veins can be seen under the skin of the highly enlarged breasts. During lactation, the mammary gland is affected by the prolactin from the anterior pituitary gland, causing the glandular ducts, glandular lobes and alveoli to highly proliferate, hypertrophy and expand. The mammary gland becomes noticeably swollen, hardened and slightly painful. During pregnancy and lactation, benign tumors may become malignant and malignant tumors may develop rapidly, so attention should be paid. ???As women's ovarian function declines, they experience menopause. After menopause, the breasts may swell due to fat deposition, but the glands generally shrink, the milk ducts shrink or even disappear, the lobule structure is significantly reduced, the breasts gradually shrink, lose elasticity and sag, which is more obvious in multiparous women. As we age, only the skin folds, areola and nipple are left on the breast.
