These differ for transwomen and transmen because testosterone’s effects are so hard to disguise. A transwoman who has gone through male puberty will bear its legacy for life: a deep voice and Adam’s apple; marked facial features; facial and body hair; and an enlarged frame with big hands and feet. The legacy of pubertal oestrogen for transmen is less visible, and can be masked fairly successfully by taking testosterone in adulthood (except for breast growth, which can be undone only by mastectomy).
