Family elders of male laryngeal nodes are not prominent, this situation, not no laryngeal nodes, just a smaller laryngeal nodes, looks less obvious.
2. Obesity: obese people neck part of the fat, the laryngeal knot may be covered up, so it is not obvious.
3. Sex hormones: the appearance of the Adam’s apple is closely related to the secretion of androgens, which may be genetically related, such as the sex chromosomes, X or Y chromosomes, or a genetic defect. It may also be related to the endocrine glands, and low levels of androgens may cause the absence of a laryngeal node.
In addition, the male secondary sex characteristics develop in the following order: straight pubic hairs appear as the testicles increase in size, pubic hairs appear as the penis develops and increases in height, and the laryngeal nodes increase in size as the voice lowers. Therefore, the laryngeal nodes need to reach a certain age to increase in size.
