VM 580 EXAM REVISION QUESTIONS AND
100% CORECT ANSWERS!!
A
What disease process is NOT an indication to castrate?
a. Prostatic neoplasia
b. Testicular neoplasia
c. Perineal Hernia
d. Population Control
Population control, behavioral, testicular neoplasia, perineal hernia treatment, benign
prostatic hyperplasia (BPH), testicular torsion/abscessation/trauma
What are indications for castration?
Intact male dogs exhibit more roaming behavior and have increased breeding
opportunities
Why does population control and behavior go hand in hand in male dogs?
Escaping/roaming behavior, aggression, mounting, urine spraying
What behaviors are decreased from neutering males?
Older dogs (median 10 years), cryptorchid testicles (13.6 times)
What things increase the risk of testicular neoplasia?
Palpable mass, contralateral testicular atrophy, hair loss or signs of feminization
What incidental physical exam findings are associated with testicular neoplasia?
Ultrasound
this can be used to confirm testicular neoplasia and examine lymph nodes
40
, > _____% of diagnosed cases of testicular neoplasia have >1 primary tumor
B
Why are cryptorchid testicles at an increased risk for developing neoplastic lesions?
A. Darwin's natural selection
B. Abdominal/inguinal position increases thermal exposure
C. They are cryptorchid because they have neoplastic lesions
D. Exposure to abdominal fluid
Sertoli cell tumor, interstitial (leydig) cell tumor, seminoma
What are the 3 common types of testicular neoplasia?
A
Which testicular tumor most likely result in changes termed feminization?
A. Sertoli cell tumor
B. Interstitial (Leydig) cell tumor
C. Seminoma
Gynecomastia, attraction of other male dogs, alopecia, atrophy of contralateral testicle,
squamous metaplasia of prostate gland
What are clinical signs of sertoli cell tumor feminization?
Aplastic Anemia
What can happen with excess estrogen?
Gynecomastia
one of the signs of sertoli cell tumor feminization - development of mammary glands
Bone Marrow Suppression
this can also occur with sertoli cell neoplasia - estradiol-17B is increasing to
testosterone/estradiol ratio is decreasing - may lead to bone marrow hypoplasia which can be
fatal
