If you scientifically explain why you love 'boobs', it will be like this

Human babies get the nutrients they need to grow from their mother's milk. The breast is a symbol of life that nurtures the life of the baby, but it is not only the baby who loves the breast. The increasing number of women undergoing breast augmentation surgery suggests that women's breasts are an important part of both men and women, but what kind of function does such breasts have? It is scientifically explained whether it is done.

The Science of Boobs-YouTube


The breast is an organ that nourishes the baby ...

Breast milk is made from proteins, sugars and fats extracted from the blood. Breast milk plays a major role in the evolution of mammals.

Birds and reptiles grow by eating foods such as insects brought by their parents, but as the name suggests, mammals have the great advantage of producing essential nutrients for babies in their mothers and supplying them as breast milk. It has become.

Breast size, weight, and shape vary from person to person, but genetic factors are also involved. Fifty percent of women have asymmetric breast sizes and shapes, most of which are larger on the left. Such left-right asymmetry is a normal phenomenon, but the reason why female breast size becomes left-right asymmetry has not been completely scientifically elucidated, and hormonal changes in the body that occur during puberty are predominant. It is a candidate.

In addition, the size of the breast of a woman may change with each menstrual cycle, and to be precise, the secretion of estrogen (female hormone) and progesterone affects the change in the size of a woman's breast.

Nipples and mammary glands are found in both males and females, but only females develop nipples and mammary glands during the growing season.

The surrounding ring, which is similar in color to the female nipple, is called the 'Areola', and the small protrusions on the areola have the name

'Montgomery gland'. The Areolar gland is an organ that has essential functions for baby's growth, such as not only secreting sebum that makes the baby's mouth slippery during breastfeeding, but also secreting compounds that make the baby feel 'tasty' in the nipple. There is.

There are multiple holes in the nipple that secrete breast milk, but it is not well known that they are so small that they cannot be seen with the naked eye. Also, the nipples of mothers with babies have receptors that detect when the baby has started breastfeeding, which tells the mother's brain that the baby is breastfeeding. As a result, it will be possible to continuously secrete hormones such

as 'oxytocin ', which is also called 'hug hormone' because it promotes the formation of bonds between mother and child , and 'prolactin ', which is essential for the production of breast milk. It seems that such a mother's reaction may occur even if she hears the crying of a child other than her own child.

In this way, the mother's breast has many functions that the baby must love, but even for grown-up men and women, the 'female breast' is considered to be a special part. There may be. One study found that looking at women with large breasts and hips of a certain width increased observation time for both men and women. AsapSCIENCE says that the data that about 300,000 breast implants were performed in the United States in 2014 potentially explain the special feelings people have in their breasts. The study shows that people prefer breasts regardless of shape or size, rather reflecting that medium-sized breasts were the most highly rated.

In addition, the breast is not only a place to give joy to others, but also a part to feel sexual stimulation. According to a breast study, nipple stimulation improved overall sexual stimulation by 82% in females and 52% in males.

Studies using fMRI scans have also shown that the area of the brain that responds to clitoral and vaginal stimulation was the same area as when the nipple was stimulated.

Breasts are the source of such nutritional and joyful wonders, but they have the drawback of being prone to illness. This is because cells with a higher number of divisions have a higher possibility of mutation, but the breast is an organ in which cell division occurs frequently due to the effects of hormones and the like.

Breast cancer is also said to be the most common cancer confirmed in North America.

Female hormones secreted during breastfeeding have the property of stimulating the division of mammary gland cells, but environmental chemicals that mimic estrogen and affect cell proliferation have been discovered from pesticides, industrial products, foods, etc. I am. Avoiding unreliable products may reduce your risk of developing breast cancer.

The same study of breast cancer also discovered new risk factors involved in the development of breast cancer, such as breast density, first birth, and

tumor suppressor genes such as BRCA1 and BRCA2. , May be useful to remember.
