Generally, boys complete their physical development by ages 20–24; however, the rate of skeletal growth primarily depends on physiological (biological) age. Puberty in boys typically begins between ages 12 and 14, during which they may grow 9–12 cm per year. The age at which an individual boy stops growing varies considerably and is influenced by multiple factors—primarily genetics, nutrition, and physical activity. To definitively determine whether a boy has completed growth, it is advisable to consult a reputable hospital promptly for evaluation. An X-ray examination can assess whether the epiphyseal growth plates have fused, thereby confirming whether growth has ceased.
