  4. 4. INTRODUCTION  Endocrine system - second key regulator of organ systems Thyroid gland – one of the largest endocrine gland metabolism  growth development.  Well functioning TG - pivotal for a healthy body & to conceive a healthy child. 4
  5. 5. 5 ANATOMY
  6. 6. Thyroid means “oblong sheild.” Brownish-red, butterfly shaped structure - front of the neck . justinferior to larynx from C5 to T1 6
  7. 7. Weight 25 gm./1 ounce Each lobe - 5 x 3 x 2cm Isthmus – 1.25cm x 1.25 cm x 1.25 cm. Slightly heavier in females enlarging during menstruation and pregnancy.  Highly vascular receiving 80-120ml of bloodmin. 7
  8. 8. Microscopic anatomy includes thyroid follicles -spherical. 0.02 to 0.9mm in diameter.  with a central colloid core surrounded by a simple epithelium and basal lamina. Colloid -thyroglobulin. Parafollicular cells /“C”cells. 8
  9. 9. THYROID HORMONES Thyroid gland – large storage capacity , store thyroid hormone for 2 to 3 months. Thyroid hormone include 1. 93% Thyroxine (t4) - 10-25pmol/ltr (normal) 2. 7 % Triiodothyronine(t3) - 1.1-2.3nmol/ltr 3. Thyrocalcitonin – parafollicular cells  Normal value - TSH - 0.45 -5.5mmol/ltr T3 is about 4 times as potent as T4. 9

  21. 21. THYROID DISORDERS Thyroid abnormalities – autoimmune, 10 times more common in women than men. Antigens Antibody  Thyroglobulin(Tg)  Antithyroglobulin(anti-tg)  Thyroid  Antimicrosomal thyroid peroxidase(TPO) peroxidase (anti-TPO)  TSH receptor(TSHR)  Anti-tsh receptor(anti-tshr)  Na /I symporter(NIS)  Anti-na/I symporter(anti – 21 NIS)

  26. 26. Effect of Hyperthyroidism in Reproductive system FEMALES MALES Increased mean Increased estrogen plasma estrogen level.&LH production. level . Increased level of SHBG. Defective Increased incidence of spermatogenesis. oligomenorrhea Low sperm count with amenorrhea & anovulation. sperm motility defect. . 26
  27. 27. May cause early onset of menopause Symptoms – lack of menstruation, hot flushes, insomnia, mood swings – mistaken for menopausal symptoms. Treatment of hyperthyroidism – alleviate symptoms of ,or the actual onset of early menopause. 27
