Early cessation of growth at age 13 in an athletic boy
academic.oup.com
Examination revealed adult-like pubic hair quality, extending across pubis but sparing medial thighs, with testes long axis measuring 4.5 cm. Facial hair reached upper lip. The patient had an athletic body physique: height = 183.0 cm, weight = 77.6 kg; muscle mass = 52.9%. CDC height for age calculation revealed Z -score of 3.3 and 99.9th percentile. Growth velocity curve showed a tall stature (≥95th percentile) for the past 5 years of height measurement, with annual growth velocity decline from 8 to 2 cm per year. No limb length discrepancy has been found. An X-ray of the left hand and wrist done at chronological age of 13 years revealed advanced skeletal age closest to 18.0 years; all the epiphyses except that of the radius have fused with their shafts. Laboratory evaluation revealed a serum total testosterone of 743.2 ng/dl (normal range: 7–800 ng/dl), free testosterone of 25.8 ng/dl and Dehydroepiandrosterone (DHEA) sulfate of 211.6 µg/dl (reference values for free testosterone and DHEA sulfate have not been established for patients under age 16), estradiol of 26.9 pg/ml (normal range: 0–38 pg/ml), and free thyroxin of 1.3 ng/dl (normal range: 0.7–2.0 ng/dl). Chromosomal analysis showed normal karyotype.
What the fuck. 13 yo casually height and testmogging everyone...
