Height growth may continue even after the appearance of laryngeal nodes. The laryngeal node is a manifestation of male secondary sexual characteristics. Generally, after the age of 13, masculine characteristics tend to become obvious because of the massive release of androgens, rapid height growth, the appearance of laryngeal nodes, voice changes, and even the appearance of beards, and the gradual maturation of external genitalia such as testicles. The growth of the laryngeal node is only part of the secondary sexual characteristics. Even though the laryngeal node has reached adult level, the height will continue to grow as long as puberty has not yet ended. Growth may vary from one individual to another. Some patients may develop the laryngeal nodes and beard first, and then continue to grow in height. Some people may grow in height first and then develop a laryngeal node, so the laryngeal node is not an indicator of height growth.
