Breast development Breast development is mainly influenced by various hormones in the reproductive endocrine axis, such as gonadotropin and lactogen from the pituitary gland, estrogen and progesterone from the ovaries, as well as hormones from the adrenal glands and thyroid gland, and growth hormone from the pituitary gland, in order to fully develop the breast. Secondly, breast development is also influenced by genetic factors, nutrition, climatic conditions, the environment and many other factors. Breast development refers to the period between sexual development and maturity during puberty, generally 3-5 years, the early and late start of breast development is to some extent related to race, living conditions, nutritional status and other factors, white women generally start breast development at the age of 9-13; black people 1-2 years later, China’s female breast development time is 12-15 years old, in recent years, due to the improvement of living standards and material conditions In recent years, due to the improvement of living standards and material conditions, the breast development of our girls has also been advanced. The effect of anterior pituitary hormones on breast development: The anterior pituitary gland and ovaries maintain a functional regulatory relationship with each other under normal conditions. When ovarian function is low, anterior pituitary function is increased, and conversely, when ovarian function is hyperactive, anterior pituitary function is decreased. The effect of ovarian hormones on breast development: Since puberty, women mature follicles in the ovaries and secrete large amounts of estrogen, at which time the mammary glands develop rapidly and become significantly enlarged. This function is under the control of anterior pituitary hormones for estrogen to do its work. The amount of estrogen is proportional to the regeneration of the milk ducts within a certain range. Excessive estrogen not only fails to promote the development of the mammary glands, but on the contrary inhibits it. This is because large amounts of estrogen inhibit the secretory function of the anterior pituitary gland. The secretion of gonadotropins in the anterior pituitary gland is reduced, which also contributes to low endocrine function of the ovaries and thus affects the development of the breast. Before the ovaries secrete luteinizing hormone, the development of the glandular lobules is extremely limited. After sexual maturation, especially during pregnancy, the glandular lobules develop fully under the combined and repeated action of progesterone and estrogen. Otherwise, the epithelial cells of the terminal milk ducts are prone to abnormalities, such as cystic hyperplasia. The effect of adrenocortical hormones on breast development: The adrenal cortex secretes a variety of hormones, including those that regulate sexual characteristics, including adrenal solid ketones and male ketones in men and progesterone and estrone in women. Therefore, when adrenal cortex hyperplasia or tumor occurs, it can stimulate the development of mammary glands in young men and women. If the adrenal glands of lactating animals are removed, lactation can be stopped, and if corticosteroids are injected, lactation can be restored. The effect of the thyroid gland on mammary gland development: In young children with hypothyroidism, the whole body is stunted and the mammary gland does not develop, but if thyroid preparations are given, the whole body and mammary gland development are normal. The effect of thyroid on mammary gland is indirect. When thyrotropin secretion from anterior pituitary gland decreases, thyrotropin secretion decreases and mammary gland development is affected. In the case of pregnant women, although there are often a lot of hormones in the body to promote breast development, but their mammary glands still do not have glandular vesicles, the breasts are composed of many long breast ducts, which means that the breast has not developed, and only after pregnancy, the estrogen in the blood greatly increased, due to the increase in estrogen, so that the breast ducts grow very long, and give birth to many branches, the increase in blood progesterone, so that the glandular vesicles at the end of the ducts gradually The increase in progesterone in the blood causes the alveoli at the end of the ducts to gradually enlarge and the lobules to gradually develop, which makes the breast more distended. Experiments have also shown that estrogen mainly stimulates the proliferation of milk ducts, while progesterone promotes the development of glandular alveoli. However, these two hormones alone cannot fully develop the breasts, and the combined effects of anterior pituitary hormones, i.e. growth hormone, glucocorticoid (or ACTH) and prolactin, are necessary to fully develop the breasts. Breast aesthetics and health care For patients with breast hypoplasia resulting in small breasts, the cause must first be identified when correcting the problem. If it is caused by a disease, the disease should be treated first. For simple dysplasia, it can be corrected by medication, diet, massage, exercise, and mammaplasty surgery. Patients can regulate their own diet. It is important to eat more foods rich in vitamin E and B group. This is because vitamin E promotes the development and perfection of the ovaries, which leads to an increase in mature egg cells and enlarged corpus luteum cells. The oocyte is an important place to secrete hormones, and when the secretion of estrogen increases it stimulates breast development, so you should eat more cabbage, cauliflower, sunflower oil, sesame oil and other foods rich in vitamin E. Vitamin B is an indispensable component for the synthesis of hormones in the body. Vitamin B2 is rich in animal offal, eggs, milk and soy products, and vitamin B6 is rich in cereals, beans, lean meat and other foods. In addition, food therapy can also be used, such as lamb stewed in soy milk, carp stewed in seaweed, lychee porridge, etc. Can also be treated by massage techniques, through the massage of the chest, breasts to increase breast. Specific methods: 1, straight push breast: first with the palm of the right hand in the upper part of the left breast, that is, below the clavicle force, evenly and gently pushed straight down to the root of the breast, and then pushed back up along the original route, do 20-50 times, the same method for the left hand to massage the right breast. 2, side push breast: with the left hand palm root and palm surface from the middle of the chest force, lateral push press the right breast to the armpit, return with five fingers finger surface will be breast tissue back, repeated 20-50 times, the right hand massage left breast. 3, hot massage breast: every night before bed with a hot towel on both sides of the breast 3-5 minutes, with the palm of the hand massage around the breast, from left to right, massage 20-50 times. Just massage once a day according to the above method, adhere to the massage for 2-3 months, can make the breast augmentation 2-3 cm. 4, exercise is also a good recipe for breast enlargement. Participate in physical exercise, pay special attention to exercise chest muscles, so that the pectoralis major muscle developed to promote breast augmentation. Usually pay attention to standing and walking posture, often keep the chest and abdomen, in order to facilitate breast development. The actual fact is that you will be able to get a good deal on your own. In addition to the above methods, breast augmentation plastic is also an effective way to increase the breast and make it beautiful. In recent years, this surgery has been commonly carried out in China, on small breasts, flat breasts to perform breast augmentation plastic, achieved a more desirable effect of breast augmentation. The beauty of the female breast, the breast naturally plays a decisive role. The shape of the breast in adolescence is the most ideal stage of breast shape in a woman’s life, characterized by conical shape, nipple areola is yellowish brown, located in the center of the cone. A well-developed breast should be basically symmetrical on both sides. There is no strict age limit for adolescent breasts, generally referring to unmarried women aged 15-25, or under 30, so also known as unmarried breasts; some women are past puberty, but still unmarried. But still not married, the breast is still in the state of adolescence, also known as adolescent breast. To keep your breasts beautiful, breast health is very important.
