Essentials of Steroid Structure, Nomenclature, Reactions, Biosynthesis, and Measurementsverview will focus on the primary hormones of the gonads (progestins, androgens, and estrogens) and will omit detailed discussion of the adrenal corticoids. It should be recognized, however, that the gonads may produce corticoids and the adrenals secrete progestins, androgens, and estrogens.

There are also peptide hormones of neurosecretory origin that are secreted by the hypothalamus and the posterior pituitary gland (see Chapters 2, 4, and 13). Finally, some of the chemicals that transmit information between neurons—the neurotransmitters—are derivatives of sim

Hormonal Actions on the Sexual Differentiation of the Genitalia and the Gonadotropin-Regulating Systtion that there was a very well-developed secretory interstitium in the testes of pig embryos at the time of genital tract differentiation indirectly supported this notion. The idea of hormonal regulation of the process of sexual differentiation was given further impetus by studies of a phenomenon k

Perinatal Hormones and Their Role in the Development of Sexually Dimorphic Behaviorsissues. It is only more recently that the idea of an influence of steroids on the differentiation of neural substrates for sexual behavior has been brought forward and systematically examined. The purpose of this chapter is to survey the evidence on which the notion of behavioral differentiation is

Early Organizational Effects of Hormones [coldblooded vertebrates] the environment assumes a greater part in fashioning the end-product than in almost any other genetically controlled process” (Dodd, 1960). In particular, behavioral sex differentiation provides a dramatic example of a permanent effect of sex steroids on brain function. Th
