Testosterone levels surge dramatically during puberty, increasing up to ten times in boys compared to childhood levels, which triggers key physical changes like genital growth, voice deepening, muscle development, and body hair emergence [1][2][3][4][5]. Puberty in males is initiated by brain signals prompting the testes to ramp up testosterone production, alongside dihydrotestosterone, driving secondary sexual characteristics and libido [3][6]. These hormonal shifts, including testosterone, also contribute to mood fluctuations and overall pubertal development [7][8].
