    Abstract:
    An overview of the sex hormones is presented. Testosterone is a natural androgen produced in the testes, adrenal glands, and ovaries. It has anabolic as well as androgenic effects. Testosterone is used to treat inoperable breast cancer and osteoporosis, and to stimulate erythropoesis. Androgens are absolutely counterindicated in cases of prostate cancer. Estrone, estradiol, and estriol are natural estrogens produced in the ovaries, placenta, testes, and adrenal glands. These hormones also influence the production of gonadotropins by the pituitary gland. Estrogens are used to treat menopausal disorders, ovarial insufficiency, estrogen-independent breast cancer, prostate cancer, and in some cases pregnancy disorders. Estrogens and progestagens are 2 components used in oral contraceptives. Progesterone, a natural progestagen, is produced by the corpus luteum. It promotes the proliferation phase of the endometrium, fertilization, and nidation, and it works to maintain pregnancy. Progesterone is used to treat spontaneous abortion, corpus luteum insufficiency, and endometrial cancer.
