II. Definitions

  1. Estrogens
    1. Estrogens are synthesized in vivo and maintain female sex characteristics
    2. Estrogens target receptors in gynecologic organs, as well as male Ledigs Cells and Prostate Glands, and heart, skin, Kidney, liver, brain
  2. Estradiol
    1. Most potent, natural form of Estrogens in humans

III. Physiology

    1. menstrualCycle.png
  2. Estrogen effects
    1. Breast development (ducts, fat)
    2. Female genitalia
    3. Secondary sex characteristics
    4. Uterine endometrial lining proliferation in the Proliferative Phase of menstual cycyle
  3. Symptoms associated with physiologic increased Estrogen levels (e.g. Premenstrual Syndrome)
    1. Swollen or engorged Breast tenderness
    2. Water retention
    3. Irritability (decreased Serotonin)
    4. Headaches
    5. Visual disturbance
    6. Memory difficulty
    7. Sweet craving
  4. Excess Estrogen effects (e.g. Oral Contraceptives)
    1. Contraception
      1. Limits FSH and LH rise, preventing Ovulation
      2. Cervical Mucus thickening (more hostile to sperm)
      3. Inhibit ovum implantation in Uterus
    2. Adverse effects
      1. See Oral Contraceptives for adverse effects
      2. Venous Thromboembolism Risk
      3. Endometrial Hyperplasia or Endometrial Cancer (Unopposed Estrogen, without Progesterone)
      4. Hypertension
  5. Estrogen Deficiency
    1. See Menopause
    2. See Premature Ovarian Failure
    3. Hot Flushes
    4. Vaginal Atrophy
    5. Osteoporosis

IV. Labs: Normal Levels

  1. Male: 6 to 46 pg/ml
  2. Female
    1. Follicular Phase: 30 to 90 pg/ml
    2. Luteal Phase: 70 to 300 pg/ml

Definition (NCI_NCI-GLOSS) A form of the hormone estrogen.
Definition (NCI) A steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. Typically esterified, estradiol derivatives are formulated for oral or parenteral administration. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. Estradiol exhibits mild anabolic and metabolic properties, and increases blood coagulability.
Definition (NCI) The most potent form of the naturally occurring steroid sex hormone in humans, produced by ovary, placenta, testis, and in small amount by adrenal cortex. Estradiol binds to a specific intracellular estrogen receptor located in female organs, breasts, hypothalamus and pituitary. The receptor-ligand complex promotes gene expression necessary for the maintenance of fertility and secondary sexual characteristics in females. In addition, estradiol exhibits mild anabolic and metabolic properties, and increases blood coagulability. Estradiol, the principal intracellular human estrogen, is substantially more active at the cellular level than its metabolites, estrone and estriol.
Definition (MSH) The 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position. Estradiol-17-beta is the most potent form of mammalian estrogenic steroids.
Definition (CSP) generally refers to the 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position; estradiol-17-beta is the most potent form of mammalian estrogenic steroids.
Definition (PDQ) A steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. Typically esterified, estradiol derivatives are formulated for oral or parenteral administration. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. Estradiol exhibits mild anabolic and metabolic properties, and increases blood coagulability.
