Lay opinion vs evidence: Testosteron Kinder

The topic of testosterone in children is one where lay opinions often diverge sharply from scientific evidence. Online, claims circulate that a 'low testosterone level' in boys causes developmental delays or that testosterone supplementation is beneficial. In reality, testosterone in childhood is physiologically very low and only rises during puberty. Routine testing of testosterone in healthy children is not medically indicated. Administering testosterone to children without confirmed hypogonadism is not only ineffective but can cause serious side effects such as premature growth plate closure, liver damage, and psychological effects. Evidence from pediatric endocrinology is clear: testosterone therapy is only indicated for well-defined conditions (e.g., congenital hypogonadism) after rigorous specialist diagnosis. Lay opinions driven by self-optimization or 'biohacking' are dangerous here. Caveat: The provided contexts contain no specific information on testosterone in children; this answer is based on general medical knowledge.
