[摘要]：A 14-year-old boy with an unremarkable medical history presents because of lack of pubertal development. He has always been relatively short, but his growth velocity is slowing as compared with that of his peers. His height is 146 cm 957.5 in., <3rd percentile for age), and his weight is 37 kg 982 lb, 3rd percentile). His father, who is 168 cm (66.1 in.) tall, continued to grow until his second year in college; his mother is 153 cm (60.2 in.) tall and began menstruating at the age of 14.0 years. The patient's target height on the basis of the parental heights is 167 cm (65.8 in.). The physical examination reveals Tanner stage 1 pubic hair and prepubertal-sized testes. How should the boy be evaluated and treated? |
