Throat nodes in boys usually start to grow at the age of 12 to 18, but there are individual variations. The Adam’s apple is one of the signs of maturity in boys, and it usually appears when the secondary sexual characteristics develop (12~18 years old). With the onset of puberty, androgens in boys’ bodies continue to increase, so the laryngeal nodes will slowly protrude. At this time, boys’ voices will also change a bit and will change to a lower voice. However, for different boys, there is no specific time for the growth of the laryngeal knot because of the different secretion of androgen in the body. Some boys will not have a particularly pronounced laryngeal knot because they are more obese and have a thicker neck. If a boy does not have a laryngeal knot by a certain age, please see a doctor at a regular hospital for an evaluation.
