What is the size of a woman's chest related to? Women's breasts are big and small, depending on it

Some people say that the size of the chest is related to female obesity, while others say that the size of the chest is related to height. There are many women in life who want to have full breasts, but some women are born with sadness. Many women blindly believe that the size of their breasts is related to massage, so they often massage to expand their breasts. In fact, the size of a woman's chest is determined by her body hormones.

What determines the size of a woman's breasts?

1、 Estrogen

Estrogen is mainly produced by the secretion of ovarian follicles. During puberty, when ovarian follicles mature, they begin to secrete a large amount of estrogen, which stimulates the mammary gland. Estrogen can promote epithelial growth in the mammary ducts and the development of tissue around the breast lobules, which can prolong and branch the breast. However, estrogen requires a complete pituitary functional system to promote breast development. During pregnancy, estrogen can work with other hormones to promote breast development and milk production. In addition, estrogen expands breast blood vessels and increases breast transparency.

2、 Pregnancy hormone

Pregnancy hormone, also known as lutein, is mainly secreted by the corpus luteum of the ovaries or by the placenta during pregnancy. Among Progestogen, progesterone, which has physiological activity, is mainly used to promote the development of breast lobules and acini, and with the cooperation of estrogen, the breast can be properly and fully developed. The large dose of Progestogen has the effect of inhibiting Prolactin. Experiments show that Progestogen needs to have a complete pituitary functional system with the cooperation of estrogen to stimulate breast development.

3、 Prolactin

It is a protein hormone secreted by eosinophils in the anterior pituitary gland. It mainly promotes the growth of Mammoplasia. During puberty, Prolactin, in cooperation with estrogen, pregnancy hormone and other hormones in the body, makes the breast develop well. During pregnancy, Prolactin fully develops the breast, making the final duct of the breast lobule develop into small acini, preparing for postpartum lactation. It can be seen that the size of a woman's chest is mainly related to hormones in the body, which can directly be said to affect breast development. For women with low levels of hormones, the stimulation to the breasts will also decrease and the development of the breasts will also increase. Therefore, adolescent women can consume more hormonal foods, supplement their body hormones, and increase the probability of preventing development.
