++

  • The biosynthesis and physiological and pharmacological actions of the estrogens, progestins, and androgens

  • A detailed discussion of gonadotropin and gonadal steroid concentrations during the menstrual cycle, the effects of cyclical gonadal steroids on the reproductive tract, and the metabolic effects of estrogens, progestins, and androgens

  • A detailed discussion of fertility induction and the general principles of drug therapy of pregnant women, and the prevention or arrest of preterm labor

  • A detailed discussion of the secretion and transport of testosterone, the physiological and pharmacologic effects of androgens, and the effects of androgens at different stages of life
