Male repro epididymis vas seminal vescile

  1. 1. Maj Rishi Pokhrel rongon28us@gmail.comSlideshare.net
  2. 2. Introduction • Parts – Testis – Genital ducts • Epididymis • Ductus Deferens – Accessory Glands • Seminal Vesicles • Prostate • Bulbouretheral glands – Penis
  3. 3. Epididymis • Along posterior (post-lat) border of testis • Single long tube, coiled – 6 m • Receives efferent ductules at head • Continuous with Ductus Deferens • Parts: head, body, tail
  4. 4. Epididymis • Sinus of epididymis: narrow slit b/w epididymis and testis • Blood supply: branch from testicular A • Dev: mesonephric duct • Appendix of epididymis: remnant of mesonephric tubule • Paradidymis: at lower end of spermatic cord
  5. 5. Histology • Smooth regular lumen • Pesudostratified columnar with stereocilia • Circularly arranged smooth muscle fibres – Thicker at distal end
  6. 6. Epididymis
  7. 7. Epididymis
  8. 8. Ductus / vas Deferens • Thick walled muscular tube • Tail of epididymis -> spermatic cord -> Enters abd at deep ring -> side wall & floor of pelvis ->back of bladder ->
  9. 9. Course & Relations • At deep inguinal ring: hooks around inter-foveolar ligament & inf epigastric A, • Crosses ext iliac A & V, obliterated umbilical artery, obturator N, A & V, • Cross above the ureter, approaches opposite fellow, turn downward and dilate to form ampulla • Join with seminal vesicle to form ejaculatory duct • Blood supply: artery to vas, br of inf vesical artery
  10. 10. Histology • Small lumen folded irregular • Pesudostratified columnar ep with stereocilia • Lamina propria – Fibro elastic (thin) • Muscular layer - 3, Thick, palpable (cord like) • Adventitia - fibroelastic • Surrounded by arteries, nerves, lymphatics & pampiniform plexus
  11. 11. Seminal vesicle • Paired, thin walled, elongated, lobulated sac • Blind tube folded on itself • On base of bladder above the prostate, • Post – rectovesical fascia
  12. 12. Seminal vesicle • Join lower end of ampulla of vas -> ejaculatory duct • 80% of seminal fluid, imparts motility • Vesical & middle rectal A • Dev: mesonephric duct
  13. 13. Applied anatomy • Vasectomy
