             • The female gonads, the ovaries, secrete estrogens and progestins.

                                                        Ovaries

                          Anatomy                                       endocrine portion
           The ovaries house female germ cells  ✓  related to the Graffian follicles ➔ theca and

           (oocytes) containing follicles in              granulosa cells.
           various stages of development:             ✓  Theca cells secreted testosterone and
           primordial, primary, secondary,                androstenedione which are transported to

           tertiary, and Graafian follicles.              granulosa cells (contain aromatase) to
                                                          utilize in estrogen synthesis

                           Three main estrogens                                       Transport

         •  estradiol, estrone & estriol ➔ The most potent is  Transported in blood bound to sex
             estradiol.                                                 steroid–binding globulin (SSBG)

         •  Estrone & estriol are formed in peripherals, &              & albumin
             secreted in conc. during pregnancy, respectively
