Study Notes

Introduction to the Reproductive System

Definitions

  • Gamete: haploid cell
  • Male gamete: spermatozoa
  • Female gamete: oocyte or ovum

Anatomy of the Pelvic Cavity

  • Lies within the bony pelvis, between the pelvic inlet and the pelvic outlet
  • Continuous with abdominal cavity
  • Pelvic floor: internal wall of skeletal muscle that separates the pelvic cavity and the perineum
  • Perineum: inferior to pelvic floor, situated between the proximal parts of lower limbs
  • Pelvic roof: formed by parietal peritoneum (lining of abdominal cavity)
  • Peritoneal cavity: space between visceral and parietal cavity

Female Reproductive System

  • Ovaries
  • Accessory reproductive organs: uterine tubes, uterus, vagina
  • Layers of the uterus wall: perimetrium, myometrium, endometrium
  • Ovulation and menstruation:
    • Ova released from ovaries into peritoneal cavity
    • Ovum gathered by fimbriae into infundibulum of uterine tube
    • Ovum moved along uterine tube by cilia until it reaches the uterus
    • During menstruation, an unfertilized ovum is expelled by contractions of the myometrium
  • Early pregnancy:
    • Fertilization: usually occurs in the ampulla
    • Implantation: usually occurs in the body of the uterus
    • Ectopic pregnancy: fertilized ovum implants outside of the uterine cavity

Male Reproductive System

  • Testes
  • Accessory reproductive organs: vas deferens, prostate gland, penis
  • Surface anatomy of the male perineum
  • 3 cylinders of erectile tissue become filled with blood at arterial pressure during erection
  • Retrovesical pouch: double folding of peritoneum located between the rectum and the bladder

Development of the Testes

  • During development, testes originate on the posterior wall of the abdominal cavity
  • By birth, they have descended into the scrotum through the anterior abdominal wall

Production of Spermatozoa

  • Produced in the seminiferous tubules
  • Sperm pass to rete testis, then into head of epididymis
  • Epididymis becomes vas deferens

Spermatic Cord

  • Contains: vas deferens, testicular artery, and pampiniform plexus of veins
  • Sperm pass from the testes via the vas deferens (part of the spermatic cord)
  • Each spermatic cord passes through the anterior abdominal wall to reach the pelvic cavity
  • Each vas deferens connects with the duct from a seminal gland - ejaculatory duct
  • Right and left ejaculatory ducts join together within the prostate and drain into urethra
  • Urethra opens at the external urethral meatus of the penis

Sterilization

  • Females: tubal litigation (uterine tubes clipped, cut or cauterized)
  • Males: vasectomy (vas deferens transected and lumen sutured shut)
