Definition: the process by which children acquire behaviours deemed appropriate for. Males and females develop distinct reproductive anatomy. 23 chromosomes from male parent combine with 23 chromosomes from female: male sex hormones, without androgens, we would all develop female external reproductive organs.

Begins with implantation of a fertilized ovum and concludes with development of the. During the first six weeks, embryonic structures of both sexes develop along similar.

Chapter 5: the male sex hormone that fosters the development of duct system and is connected with the sex drive. By 10 weeks after conception, testes and ovaries have descended.
