  1. 1. FEMALE REPRODUCTIVE SYSTEM
  2. 2. FEMALE REPRODUCTIVE SYSTEM <ul><li>Consists of paired internal ovaries , paired uterine tubes (oviducts) , and a single uterus , and vagina </li></ul><ul><li>Accessory gland – mammary gland </li></ul>
  3. 3. FEMALE REPRODUCTIVE SYSTEM
  4. 4. ANATOMY
  5. 5. MAIN FUNCTION/S <ul><li>Secretion of female sex hormones </li></ul><ul><li>Production of oocytes for fertilization by sperm </li></ul><ul><li>Transportation of embryo to the uterus </li></ul><ul><li>Implantation of embryo </li></ul><ul><li>Development of fetus (pregnancy) </li></ul><ul><li>Nutrition of newborn </li></ul>
  6. 6. OVARIES <ul><li>Flattened almond – shaped bodies </li></ul><ul><li>Situated deep in the pelvic cavity </li></ul><ul><li>One section is attached to the broad ligament by a peritoneal fold, mesovarium </li></ul><ul><li>Another section is attached to the uterine wall by ovarian ligament </li></ul>
  7. 7. OVARIES <ul><li>Surface is covered by simple squamous or cuboidal epithelium called germinal epithelium </li></ul><ul><li>Under the covered surface is the tunica albuginea made of dense irregular connective tissue </li></ul><ul><ul><li>Responsible for whitish color of ovary </li></ul></ul>
  8. 8. HISTOLOGY
  9. 9. HISTOLOGY
  10. 10. HISTOLOGY
  11. 11. OVARIES <ul><li>Below that tunica albuginea is the cortex of the ovary </li></ul><ul><ul><li>Predominance of ovarian follicles </li></ul></ul><ul><li>Deep in the cortex is highly vascularized connective tissue core of ovary, medulla </li></ul><ul><ul><li>No distinct boundary line exists </li></ul></ul>
  12. 12. HISTOLOGY
  13. 13. HISTOLOGY
  14. 14. HORMONES (OVARIES) <ul><li>Estrogen </li></ul><ul><li>Progesterone </li></ul>
  15. 15. ESTROGEN <ul><li>Manufactured mostly in ovaries by developing egg follicles </li></ul><ul><li>In addition, produced by the corpus luteum, placenta, liver, breasts and adrenal glands in smaller quantities </li></ul><ul><li>Essential to the menstrual cycle </li></ul><ul><li>Prepares uterus for pregnancy </li></ul><ul><ul><li>Enriching and thickening of endometrium </li></ul></ul>
  16. 16. ESTROGEN <ul><li>Contributes to the development of secondary characteristics </li></ul><ul><ul><li>Breasts, widened pelvis, increased body fat in buttocks, thigh and hip region </li></ul></ul><ul><ul><li>Less facial hair and smoother skin </li></ul></ul><ul><li>Luteinizing hormone (LH) and Follicle stimulating hormone (FSH) help to control production of estrogen </li></ul>
  17. 17. PROGESTERONE <ul><li>Responsible for the changes in the endometrium in the second half of the menstrual cycle </li></ul><ul><li>For fertility and pregnancy </li></ul><ul><li>Prepare the endometrium for implantation of fertilized egg and its development </li></ul><ul><li>Maintain the uterus throughout pregnancy </li></ul>
  18. 18. PROGESTERONE <ul><li>Low progesterone hormones have negative influences on your body, fertility, pregnancy and can even lead to an expelling of a fertilized egg </li></ul>
  19. 20. Histology of egg cell
  20. 22. <ul><li>The ovum or the female gamete is much larger than the sperm in size. </li></ul><ul><li>It is non - motile and laden with different types of energy rich materials like yolk, glycogen and proteins accumulated in its cytoplasm. </li></ul><ul><li>It is enclosed by one on more egg envelops. Size of ovum varies in different animals and depends upon the amount of yolk. </li></ul>
  21. 23. <ul><li>On the basis of amount of yolk, the ovum can be microlecithal (small sized egg with very small amount of yolk) Human ovum is microlecithal. </li></ul><ul><li>mesolecithal (egg containing moderate amount of yolk) and </li></ul><ul><li>macrolecithal (containing very large amounts of yolk). </li></ul>
  22. 24. <ul><li>the cell substance is known as the  yolk  or  oöplasm,   </li></ul><ul><li>the nucleus as the  germinal vesicle, </li></ul><ul><li>  and the nucleolus as the  germinal spot.   </li></ul><ul><li>  </li></ul>
  23. 25. <ul><li>The human ovum is surrounded by a number of egg envelopes: </li></ul><ul><li>vitelline membrane - A thin, inner transparent layer secreted by the ovum itself. </li></ul><ul><li>Zona pellucida - A thick middle layer which is transparent and non - cellular. </li></ul>
  24. 26. <ul><li>Corona radiata - An outer, thicker coat formed of radially elongated follicular cells. </li></ul><ul><li>Between the vitelline membrane and zona pellucida, there is a narrow space called perivitelline space </li></ul>
