. Serum follicle stimulating hormone (FSH), luteinising hormone (LH) and testosterone (T) concentrations in 118 boys aged 8 to 17.9 years were related to chronological age (CA), bone age (BA), genital development (G1–5+), pubic hair development (PH1–5 +) and mean testicular volume (MTV). A progressive rise in serum FSH, LH and T was noted in relation to CA, BA and all pubertal parameters studied. FSH showed an approximate twofold increase, LH an eight to tenfold increase and T a fourfold increase from pre‐puberty through to full adult maturity. The FSH/LH ratio decreased with advancing CA, BA and pubertal development.
