Why don't girls have Adam's apples?

In many people's impressions, Adam's apple is something only boys have, and around us, girls' necks are very smooth without any prominent area, so most people think that girls do not have Adam's apple. But is it really that simple? Why do boys have Adam's apples but girls don't?

In fact, girls do not have no Adam's apple, it's just that their Adam's apple does not look very obvious and many people have not noticed it. It can be seen in some ancient medical books that the structure of the larynx of women, like men, is supported by nine cartilages, among which the thyroid cartilage is the most important and largest cartilage.

The laryngeal cartilage begins to grow when a person is still a test-tube embryo, and it continues to develop for 5-6 years after birth. Growth and development will not stop until the first two years of puberty. Therefore, there will be no significant changes in the necks of boys and girls during this period, because the thyroid cartilages at this time have grown to similar sizes and no obvious differences can be seen.

Boys' Adam's apples tend to become larger and more obvious, mainly due to development during puberty. During this period, the most obvious changes in girls are menstruation and breast enlargement. The most obvious feature of men is that the Adam's apple becomes more and more prominent. The front end of the thyroid cartilage plate grows rapidly, causing the front-to-back diameter of the boy's larynx to expand, and the Adam's apple is very prominent.

The prominence of the Adam's apple will also cause some changes in the boy's voice. After all, the sound also needs to be transmitted through the larynx. The area here has become larger, and the crisp tone will definitely become thicker and even louder. Such changes are mainly caused by the excessive secretion of testosterone in men's bodies.

For girls, although the body also secretes some androgens, the amount excreted is very small. Women's bodies mainly secrete more estrogen. This small amount of androgen cannot promote the growth of the thyroid cartilage, so it is impossible to form a Adam's apple as large as that of boys. Of course, some female friends may grow beards due to excessive androgen metabolism in their bodies, and they may also have a small Adam's apple.

Although it is normal for men to have Adam's apple, it does not necessarily mean that all men's Adam's apples are more obvious. The existence of Adam's apple cannot be used as a criterion for judging whether a man is fully developed. Although some men's Adam's apples are not obvious, it does not mean that there is something wrong with their physical condition.
