Human Development and the Reproductive SystemThis program traces the development of a human being from conception to full-term fetus, with a focus on the functions of the male and female reproductive systems. The three stages of development in the womb—pre-embryonic, embryonic, and fetal, generated by the mechanisms of division, differentiation, morphogenesis, patterning, and growth—are illustrated, after which there is a close examination of male and female puberty—the maturation of the reproductive system and the beginning of human sexual response.
