  1. Male Genital Tract

  2. Color Code: (page 491) • Testes: B Seminal Ves: E • Epididymis: C Prostate: i • Vas Deferens: D Bulbourthral: H • Ejaculatory Duct: F • Urethra: G • Prepus (Prepuce): Around glans • Glans: Labeled

  3. Testes • Primary male reproductive organ • Sperm producing organ.

  4. Epididymis • Coiled Tubules • Seminiferous Tubules  Epididymis  Vas Deferens

  5. Vas Deferens • Tube that connects: • Epididymis  Vas Deferens  Urethra

  6. What happens with a vasectomy? • A vasectomy can be performed under local anaesthetic. During a vasectomy, the scrotum is cut on both sides and the vas deferens drawn out. The exact surgical procedure varies slightly but usually involves the vas deferens being cut and a small piece removed, with the ends being tied and /or sealed using heat.

  7. Ejaculatory Duct • Where sperm enters the urethra. • Where Vas Deferens and duct of the Seminal Vesicles combine

  8. Urethra • Tube leaving the body: • Bladder  Outside

  9. Case report • A 66-year-old white man presented to a local emergency department with fever and severe dysuria. He was admitted for antibiotic treatment of urosepsis. CT was performed and identified a tubular metallic object in the patient’s urethra. After discharge from the hospital, the patient was referred for definitive urologic evaluation of this finding.

  10. Penis • Cylindrical Organ to move semen and Urine through the urethra.

  11. Prepus (Prepuce) • Covering of the Glans. (Foreskin)

  12. Circumcision • Removal of the prepuce.

  13. Glans • Sensory center of the penis.

  14. Seminal Fluid (Semen) • Male reproductive fluid • Sperm • Fluids secreted by glands • Sugar • ***2-to-5 mls secreted per ejaculation • Average: 120 million sperm per milliliter

  16. Gland Approximate % Description • testes 2-5%[1] Approximately 200- to 500-million spermatozoa (also called sperm or spermatozoans), produced in the testes, are released per ejaculation. • seminal vesicle 65-75% amino acids, citrate, enzymes, flavins, fructose (the main energy source of sperm cells, which rely entirely on sugars from the seminal plasma for energy), phosphorylcholine, prostaglandins (involved in suppressing an immune response by the female against the foreign semen), proteins, vitamin C • prostate 25-30% acid phosphatase, citric acid, fibrinolysin, prostate specific antigen, proteolytic enzymes, zinc • bulbourethral glands < 1% galactose, mucus (serve to increase the mobility of sperm cells in the vagina and cervix by creating a less viscous channel for the sperm cells to swim through

  17. Seminal Vesicle • Connect to the vas deferens and release • Fructose • Prostaglandins • Suppress and help female contractions

  18. Prostate Gland • Chestnut shaped gland posterior to the bladder. • Produces a milky buffer that empties into the urethra.

  20. Bulbourthral Gland • “Cowper’s Gland” • When stimulated, secrete natural lubricant to aide in intercourse.
