Introduction to the development process of girls

As women age and enter puberty, various body systems have undergone major changes and are gradually becoming mature. So what is the development process of girls like? After entering puberty, the secretion of estrogen in women's bodies begins to increase, and then the second characteristic of women gradually appears, which is the development of breasts. Let's take a closer look at it.

Starting at age 7 or 8, girls' body systems begin to develop. About 2 years later, breasts begin to develop under the combined action of ovarian hormones, pituitary hormones and insulin. Hello: The age of breast development also varies from person to person, with an average of 10.8 to 11.4 years old. If breasts have not developed after the age of 16, you should be alert to whether it is delayed sexual development or ovarian hypoplasia.

Girls' breast development usually begins when their nipples start to grow, around the age of 9 to 10 years old. Initially, it is breast hyperplasia, forming a breast nucleus, which feels like a nodule or a small lump and is painful when pressed; at the age of 12 to 13, the mammary ducts and subcutaneous fat increase day by day, the breasts gradually bulge and become elastic, and the color of the areola and nipple becomes darker. The mature breast is hemispherical in shape and is located between the 3rd to 6th ribs.

When girls reach the age of 16 to 18, their chest cavity and breasts are almost mature. Use a soft tape measure to measure from the upper bottom of the breast through the nipple to the lower bottom of the breast. If the upper and lower distance is greater than 16cm, they should wear a bra.

I hope that the above analysis of the girls’ development process will be helpful to everyone. I also hope that girls can master more physiological knowledge. Don’t worry or panic about these changes in the body. These are all normal phenomena. You should learn to face the growth and development process objectively.
