You are the parent of twins, one male and one female, who are entering puberty. Describe to them the primary and secondary sex characteristics that they will each be acquiring over the next few years
What will be an ideal response?
Primary sex characteristics include the maturation of organs that are directly involved in reproduction (e.g., boys = testes, penis; girls =ovaries, vagina, uterus). For females, menarche (the onset of menstruation) is a key event. For males, spermarche (the first spontaneous ejaculation of sperm-laden fluid) is a key event. Secondary sex characteristics are signs of maturation that are not directly linked to reproductive organs (e.g., boys = facial hair, voice change, girls = widening hips and developing breasts).
