This course will present fundamental up-to-date knowledge of embryonic sexual differentiation and development, including sexual differentiation of the brain and childhood sexual developmental milestones. Genetic and embryonic development of male and female reproductive tracts will be discussed, as well as how this development is influenced by hormones and the proteins that assist in DNA replication. The latest information about oogenesis and spermatogenesis and the effect of environment on these processes will be presented. We will explore the science of the continuum of embryonic development, as well as discuss embryonic stem cells and their functions. Other topics will be the ways in which the biology of an individual may develop differently from what we in our society consider the "binary norm," and the genotype and phenotype differences that lead to intersex, such an androgen insensitivity, Klinefelter's and Turner's syndromes, and congenital adrenal hyperplasia. The final sessions will present current scientific studies of LGBT biology. Lecture (with questions). Facilitated discussion. Viewing Videos..
