  5. When does implantation occur in the cat?
    12-13 days after ovulation

    megastrol acetate, medroxyprogesterone acetate
  10. What drugs are used for induction of ovulation in the cat?

    cryptorchidism, but incidence is low (<2%)
  12. What is a popular diagnostic test for cat suspected of a retained testes?
    penile spines, presumed to be absent if no androgens are produced.
  13. What are paired 5 mm pea-shaped glands of the cat, dorsolateral to the bulb of the penis at the ischial symphysis?
    bulbourethral glands
  14. Serum concentrations of what hormones are elevated in female bitches with previous OVE?
    LH (>200 ng/ml) and FSH (>290 ng/ml)
  15. What are differential diagnosis for primary anestrus in the bitch?
    previous OVE, unobserved heat, abnormal sexual differentiation, drug-induced, hypothyroidism, systemic dz, ovarian P4 secretion, ovarian aplasia (elevated LH and FSH), and autoimmune oophoritis
  16. What can secondary anestrus in the bitch, which is prolonged interestrus interval > 10 months, be due to?
    hypothyroidism and age
  17. What is persistent estrus in the bitch?
    combined proestrus and estrus of more than 6 weeks
  18. What are causes of persistent estrus?
    hyperestrogenism caused by follicular cystic disease and ovarian neoplasia
  19. What is a cause of irregular estrus, is due to breakthrough bleeding at onset of follicular activity preceding normal proestrus?
    split heat
  20. What are 3 causes of infertility in females with abnormal estrus patterns?
    persistent estrus, irregular estrus, nonreceptive behavior at estrus
  21. What are reasons for nonreceptive behavior at estrus in the bitch?
    • poor timing of mating
    • physical abnormality of the vulva, vestibule, or vagina
    • some females wont stand for males until fertile period is almost over

    age, pain, pharmological agents, retrograde ejaculation
  24. What are some reasons for failure to copulate in the dog?
    age, overuse, psychological constraints
  25. What are some reasons for azoospermia (no sperm in ejaculate)?
    chromosomal, bilateral cryptorchidism, germinal cell aplasia, familial auto-immune thyroiditis/orchitis, segmental aplasia of duct system
  26. What are some reasons for oligospermia (abnormally low numbers of sperm in the ejaculate)?
    small testis, orchitis, prostatic disease

  29. What breeds are at risk for cryptorchidism?
    toy breeds and boxers
  30. What is the way to diagnose cryptorchidism in the dog?
    GnRH stim test for inducing measurable testosterone increase, testosterone increased 2 fold is diagnostic for cryptorchism
  31. What is the most common medical treatment for cryptorchidism?
    use of drugs providing lutenizing hormone activity
