Ja Hyang Cho, Hae Woon Jung, Kye Shik Shim
Clin Exp Pediatr. 2024;67(11):553-559.   Published online October 28, 2024
Height gains result from longitudinal bone growth. Upon adequate growth, growth plate closure limits longitudinal bone growth. To date, gonadotropin-releasing hormone analogs, aromatase inhibitors, C-type natriuretic peptide analogs, and fibroblast growth factor receptor 3 inhibitors have been studied or used as therapeutic interventions to delay growth plate closure and increase human height. The development of more effective therapeutic modalities for short stature, precocious puberty, and skeletal dysplasia is anticipated.
