Usually, it is common for some thin girls to have a lot of doubts because of the protruding Adam's apple on their necks. They think that having an Adam's apple is a physiological phenomenon unique to men. They are worried that having an Adam's apple will transform them into men and affect their future lives. To understand this problem, we must first understand how Adam's apple is produced. The human Adam's apple is composed of 11 pieces of cartilage as a scaffold, the most important and largest piece of which is called thyroid cartilage. The laryngeal cartilage of the fetus begins to develop when the fetus is two months old, and continues to grow every year until 5-6 years after birth. However, the growth of laryngeal cartilage basically stops during the period from the age of five or six to the period of puberty. The thyroid cartilage in children is the same size in both men and women. After entering puberty, male androgen secretion increases, and the upper ends of the front corners of the thyroid cartilage plates on both sides rapidly increase and protrude forward to form the Adam's apple. At the same time, the laryngeal cavity also increases significantly, almost 6 times that of a newborn. This turns the boy's original clear childish voice into a deep and thick adult voice. This sexual characteristic in men is caused by the male hormone testosterone secreted by the testicles. Although normal women's ovaries also produce trace amounts of testosterone, it is only 5% of men's, so women generally do not have Adam's apple, that is, their Adam's apple does not protrude significantly. So, why do some girls have protruding Adam’s apples? According to research, there are roughly the following reasons: First, genetic factors. The growth and development characteristics of the parents, such as height, weight, facial features, and of course the size of the Adam's apple, will be passed on to the next generation. If the father's Adam's apple is particularly prominent, the daughter's Adam's apple may be more prominent than the average person. The second is endocrine disorders. Mainly due to insufficient endocrine function. The dominant sex hormone in women is estrogen, with very little androgen. However, if endocrine disorders are caused by pathological changes in the body, such as pituitary gland tumors, ovarian hypofunction, etc., the androgen content in the body will cause masculine manifestations such as protruding Adam's apple, thickening of the voice, and hirsuteness. At the same time, some characteristics that women should have are not obvious. The third is weight loss. For women who are too thin, the fat and muscle tissue in the front of the neck are underdeveloped, so the Adam's apple will appear to protrude forward. The protruding Adam's apple in girls is mostly a manifestation of the development process. If there are no other abnormal signs, it should be normal and will have no adverse effects on gender and development. However, for the sake of caution, if a girl's Adam's apple is obviously prominent, it is best to go to the hospital for examination. If it is caused by endocrine disorders, targeted treatment is needed, and it can be cured. Also check whether there are tumors in the reproductive system and whether there are diseases in the adrenal cortex. In addition, very few girls still have male testicles in their bodies, which is medically called hermaphroditism. Such patients will not only affect gender, but also affect fertility. If the protruding Adam's apple is related to the thinness of the neck muscles, as long as you pay more attention to nutrition, strengthen exercise, and do not blindly diet to lose weight, you will not feel the protrusion of the Adam's apple after the muscles become plump.
