adolescent anabolic-steroid use stunts adult height via growth-plate closure
In plain terms: Can teenage anabolic-steroid use permanently stunt height?
Yes — androgens aromatize to estrogen, which prematurely fuses the growth plates; this is well-established endocrinology (high-dose testosterone is even used clinically to close plates in very tall teens), so steroid use before growth finishes can permanently limit height.

| Juul 2001 · Growth Horm IGF Res | mechanism | supports | moderate | High sex-steroid exposure, via aromatization to estrogen, drives epiphyseal fusion and terminates linear growth. |
| Savage 2002 · Horm Res | observational | supports | moderate | Chronic androgen excess causes early epiphyseal fusion and adult short stature in affected children. |
| Jaruratanasirikul 2011 · J Med Assoc Thai | observational | supports | moderate | Untreated early sex-steroid-driven puberty results in short adult stature from premature growth-plate closure. |
| Smith 1996 · Baillieres Clin Endocrinol Metab | mechanism | supports | moderate | Estrogen, largely from aromatized androgen, is the principal driver initiating and completing epiphyseal closure. |
| Hoffman 2009 · J Strength Cond Res | observational | supports | low | An NSCA position stand notes androgen use in adolescents risks premature epiphyseal closure and compromised growth. |
| Meazza 2017 · Ital J Pediatr | observational | supports | moderate | High-dose testosterone is used clinically in tall adolescents to induce epiphyseal fusion and reduce final height. |
Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
