Puberty

Complete overview of hormonal development and growth during adolescence.
This anatomy chart presents a clear, clinically accurate, and beautifully balanced view of hormonal development through puberty, showing how the body transitions from childhood to reproductive maturity. On the left side, the female anatomy details ovarian activation, the rise of oestrogen and progesterone, and the appearance of key physical and emotional milestones — from the first menstrual cycle (menarche) to the stabilisation of growth, mood, and fertility. On the right side, the male anatomy illustrates the gradual activation of testosterone, DHEA, and growth hormone, guiding muscle development, voice change, bone growth, and the onset of spermatogenesis.
