Jordan's study guide- PENIS Flashcards
Accessory gland all males have
Prostate
What accessory gland is important in bulls and absent in dogs and cats
Seminal vesicles
What accessory gland is absent in dogs
Bulbourethral
What’s this form of testicular hypoplasia
sorry, poor editing of the picture on my part
Bilateral hypoplasia
What is this type of testicular hypoplasia
Unilateral hypoplasia
This causes a high risk for neoplasia
may be genetic
Retained testicle
Cryptochidism
Characteristics of hypoplasia
- regular circumference
- regular sertoli cell lining
- thickened but even basal lamina
- no inflammation
- no lipofuscin
Characteristics of degeneration
Irregular tubular circumferences
- lack of tubular lining and collapse
- thickend wavy basal lamina
- Secondary inflammation
- presence of lipfucin in tubular cells
Common causes of orchitis/periorchitis
Cow: brucella abortis
Goat: brucella melitensis
Goat: brucella melitensis
Dog: brucella canis
Why are the cow and goat forms of orchitis the most important
zoonotic
potential bioweapons
Sperm will have different chromosomes than the rest of the body
sperm leaks into surrounding tissue causing immune response
incidental unless severe
Sperm granuloma
- Yellow
- Firm
- Possible hemorrhage
- benign
- spherical and well circumscribed
- can have multiple masses in one testicle
- most common testicular cancer in dogs, cats, and bulls
INterstitial (leyding) cell tumor
- white
- soft to firm
- little structure
- buldge when cut
- homogenous
- softer edges
- less demarcation
Seminoma
Firm
white
well demarcated
wrinkled
fibrous tissue holding lobules
atrophy of normal testicle
generally benign
produces estrogen
Sertoli cell tumor
What can cause this to happen to the scrotum
Frostbite
ergot
dermatitis
What can cause this to happen to the epididymis
Inflammation from sperm granulomas or infection
Symmetric enlargement
smooth
treated by neutering
Benign prostatic hyperplasia
Irregular shape and texture
From the urethra
Trasitional cell carcinoma
Developmental issue
Persistant frenulum
Problem caused by trauma
penile rupture of the corpus cavernosum
Inflammation caused by a parasite
Habronema
Failure of the male repro/urinary tract to close properly
Hypospadius
Neoplasia caused by papilloma virus
Fibropapylomatosis
Squamous cell carcinoma
TVT
