  1. 1. Female Reproductive System Anatomy<br />By <br />Dr: Mohammed Faez<br />
  2. 2. Female Reproductive System<br />The reproductive tract in women is contained mainly in the pelvic cavity and perineum.<br />It is divided to:<br />External genitalia<br />Internal genitalia<br />
  3. 3. Female External Genitalia<br />Vulva is the term given to the female external genitalia.<br />The vulva includes:<br />Mons pubis<br />Labia majora<br />Labia minora<br />Clitoris<br />Urethral opening<br />Vaginal opening<br />Perineum<br />

  5. 5. MONS PUBIS<br />The triangular mound of fatty tissue that covers the pubic bone<br />It protects the pubic symphysis.<br />During adolescence sex hormones trigger the growth of pubic hair on the monspubis.<br />Hair varies in coarseness curliness, amount, color and thickness.<br />5<br />
  6. 6. LABIA MAJORA<br />The outer lip-like structure<br />They have a darker pigmentation<br />The Labia Majora: <br />Protect the introitus and urethral openings<br />Are covered with hair and sebaceous glands<br />Become flaccid with age and after childbirth <br />6<br />
  7. 7. LABIA MINORA<br />Referred to as the “inner lips”<br />Made up of erectile, connective tissue that darkens and swells during sexual arousal.<br />Located inside the labia majora.<br />They are more sensitive and responsive to touch than the labia majora.<br />The labia minora tightens during intercourse.<br />7<br />
  8. 8. CLITORIS<br />The small penis-like structure.<br />Highly sensitive organ composed of nerves, blood vessels, and erectile tissue<br />Located under the prepuce<br />It is made up of a shaft and a glans.<br />Becomes engorged with blood during sexual stimulation.<br />Key to sexual pleasure for most women.<br />Urethral opening is located directly below clitoris<br />8<br />
  9. 9. VAGINAL OPENINGINTROITUS<br />A mucous membrane normally covers the opening into the vagina, called the hymen.<br />Using the presence of an intact hymen for determining virginity is erroneous.<br />Some women are born without hymens.<br />Posterior to the vaginal opening are the two Bartholin’s glands. <br />9<br />
  10. 10. PERINEUM<br />The muscle and tissue located between the vaginal opening and anal canal.<br />It supports and surrounds the lower parts of the urinary and digestive tracts.<br />The perinium contains an abundance of nerve endings that make it sensitive to touch.<br />10<br />
  11. 11. 11<br />
  12. 12. Female Internal Genitalia<br />The internal genitalia consists of the:<br />Vagina<br />Cervix<br />Uterus<br />Fallopian Tubes<br />Ovaries<br />

  15. 15. VAGINA<br />It is a distensible fibromuscular tube that extends from the perineum through the pelvic floor and into the pelvic cavity<br />It measures approximately 8–12 cm in length. <br />It extends from the vestibule to the uterus, and is situated behind the bladder and in front of the rectum.<br />It is directed upward and backward.<br />Its axis forming with that of the uterus an angle of over 90°, opening forward.<br />15<br />
  16. 16. VAGINA<br />The anterior wall of the vagina is related to the base of the bladder and to the urethra; in fact, the urethra is embedded in, or fused to, the anterior vaginal wall.<br />Posteriorly, the vagina is related principally to the rectum. <br />
  17. 17. VAGINA<br />The vaginal fornix is the recess formed between the margin of the cervix and the vaginal wall. Based on position, the fornix is subdivided into a posterior fornix, an anterior fornix, and two lateral fornices.<br />17<br />
  18. 18. VAGINA<br />Blood Supply<br />The blood supply to the vagina is from the vaginal artery (branch of the internal iliac artery) and the vaginal branch of the uterine artery.<br />Lymphatic drainage<br />Lymph from the upper vagina drains into the internal and external iliac nodes.<br />Lymph from the lower vagina drains to the superficial inguinal nodes<br />18<br />
  19. 19. Uterus<br />The uterus is a thick-walled muscular organ in the midline between the bladder and rectum.<br />It consists of a body and a cervix.<br />Inferiorly it joins the vagina.<br />Superiorly, uterine tubes project laterally from the uterus and open into the peritoneal cavity immediately adjacent to the ovaries. <br />19<br />
  20. 20. Uterus<br />The body of the uterus is flattened anteroposteriorlyand above the level of origin of the uterine tubes it has a rounded superior end (fundus of uterus). <br />The cavity of the body of the uterus is a narrow slit, when viewed laterally.<br />It is shaped like an inverted triangle, when viewed anteriorly. <br />
  21. 21. Uterus<br />Each of the superior corners of the cavity is continuous with the lumen of a uterine tube; the inferior corner is continuous with the central canal of the cervix<br />The body of the uterus normally arches forward (anteflexed on the cervix) over the superior surface of the emptied bladder<br />
  22. 22. Uterus<br />The cervix forms the inferior part of the uterus and is shaped like a short, broad cylinder with a narrow central channel.<br />The cervix is angled forward (anteverted) on the vagina so that the inferior end of the cervix projects into the upper anterior aspect of the vagina.<br />
  23. 23. Relations of Uterine<br />Anteriorly<br />The uterus and cervix are related to the uterovesical pouch and superior surface of the bladder.<br />Posteriorly<br />The uterus is related to the recto-uterine pouch (of douglas), which extends down as far as the posterior fornix of the vagina.<br />Laterally: the broad ligament<br />
  24. 24. Uterus<br />Blood supply<br />The uterine artery (a branch of the internal iliac artery)<br />Lymph drainage<br />Lymphatics from the fundus accompany the ovarian artery and drain into the para-aortic nodes. <br />Lymphatics from the body and cervix drain to the internal and external iliac lymph nodes.<br />
  25. 25. Uterus<br />
  26. 26. The ovary<br />The ovaries are the sites of egg production (oogenesis). <br />Like the testes in men.<br />The ovaries lie adjacent to the lateral pelvic wall just inferior to the pelvic inlet. <br />Each of the two almond-shaped ovaries is about 3 cm long and is suspended by a mesentery (the mesovarium) from the posterior aspect of the broad ligament.<br />
  27. 27. The ovary<br />Blood supply<br />The ovarian artery (a branch of the abdominal aorta)<br />Venous drainage<br />To the inferior vena cava on the right and to the left renal vein on the left.<br />Lymphatic drainage<br />To the para-aortic nodes<br />
