How big do female breasts grow before they stop growing completely?

Breasts are one of the symbols of female sexiness and perfect beauty, but with the increase of age, the breasts will gradually stop growing and developing, and in middle-aged and elderly people, the breasts will gradually become brittle. At what age will breast development of girls stop?

In the sixth week of test tube embryo development, the breast budding period begins. By the time the baby is born, the prototype of the breast is already visible.

During childhood, breasts remain static and do not change, and there is not much difference between male and female breasts. However, until puberty, the girl's breasts serve as the first signal of growth and development, just like the harbinger of spring, starting with the initial budding, and gradually becoming fuller and more mature.

At the age of 9 to 10, the girl's ovaries start to activate and secrete estrogen, and the breasts begin to grow and develop. First the nipple becomes prominent, then the mammary gland enlarges, fat accumulates, and the entire breast develops fully.

Two or three years after a girl's breasts begin to develop, she will have her first menstruation, and after about half a year, pubic hair will appear, thus entering the active puberty period.

Young girls have erect and elastic breasts because they are mainly mammary glands with less fat.

By the age of 20, the fat in the breasts increases, forming slightly sagging perfect female breasts.

It takes about four to five years for a girl's breasts to start growing and developing and to take basic shape.

By the age of 25, breast growth and development have basically stopped.

Factors affecting breast development in girls:

Breast development is mainly affected by a variety of hormones in the reproductive endocrine axis, such as gonadotropin and prolactin secreted by the pituitary gland, and estrogen and estrogens secreted by the uterus and ovaries.

In addition, the effects of adrenaline, growth hormone metabolized by the thyroid gland, and children's growth hormone metabolized by the pituitary gland are also needed so that the growth and development of the breasts can be sufficient and healthy.

Breast development is also affected by many factors such as genetic factors, nutrition, climate conditions, and the natural environment.
