  1. Describe the descent of the testicles as the animal matures.
    • testes develop in the abdomen, and once fully developed, testes migrate through the inguinal canal d/t the pulling of the gubernaculum testis
    • should occur by 6 months of age (if longer, considered cryptorchid)
  2. Why is migration of testis out of the abdomen essential for reproduction?
    to decrease temperature for successful male gamete production
  3. What structures are contained within the spermatic cord?
    • ductus deferens
    • testicular a.v., n., and lymphatics
    • mesoductus deferens
    • mesorchium
  4. What is the advantage of closed castration?
    leave fascia intact, so the vaginal cavity is not opened--> less chance of abdominal infection and peritonitis
  5. Why shouldn't you use too much force when pulling the testes out of the scrotum?
    ureters are very closely associated with the ductus deferens--> too much force while exteriorizing testes may result in damage to ureters
  6. How do you disrupt the gubernaculum/ spermatic fascia?
    strip is away from caudal to cranial (the spermatic cord is at the cranial edge, and this is what we clamp and ligate)
  7. What is the origin of the testes in the fetus?
    caudal ridge of the kidney
  8. Cryptorchidism is...
    heritable in dogs and cats (these animals should not be allowed to reproduce; orchipexy is unethical)
  9. Cryptorchidism leads to... (3)
    • neoplasia!!!! (sertoli cell tumors most common; interstitial cell/ leydig cell tumors less common)
    • testicular torsion
    • urine spraying (cats)
  10. For inguinal and subQ crypt testicles, your approach is...
    paramedian incision right on top of the testicle [if the testicle isn't in these locations, it's abdominal and you must prep for exploratory celiotomy]
  11. How do you locate an abdominal testicle?
    go to aorta, find testicular a. and v. and follow this vessel to the testicle
  12. Describe the approach to scrotal ablation.
    • scrotal and periscrotal prep
    • elliptical incision around base of scrotum
    • removed scrotal skin
    • remove testes
    • suture elliptical incision closed
