What are 4 categories of causes of testicular degeneration?
Thermal
Cryptorchidism
Hypoplasia
Chemical
Testicular hypoplasia is an inherited condition in
________
Bulls
Inflammation of the testes is known as
Orchitis
Name 4 bacterial causes of orchitis
- Brucella*
- Pseudomonas*
- Mycobacterium*
- Nocardia*
CDV
EVA
EIA
are all viral causes of ______
orchitis
This is the foreign body inflammatory reaction
to sperm which have escaped tubular structures
Sperm Granuloma
Interstitial (Leydig) Cell Tumors
are most common in this species
Dogs
This is a tumor derived from the endocrine
cells of the interstitum
Interstitial (Leydig) Cell Tumor
Testicular enlargement is RARE in this type of tumor
Interstitial (Leydig) Cell Tumor
Endocrine effect and malignancy are very very rare
to see in this type of tumor
Interstitial (Leydig) Cell Tumor
This is a tumor of spermatogonia (germ cells)
Seminoma
Cryptorchidism is a predisposing factor for this type of
non- productive tumor,
where testicular enlargement is common
Seminoma
T/F:
Seminomas result in testicular enlargement with substantial
endocrine effects
FALSE!
Seminomas DO result in testicular enlargement, but
there are NO endocrine effects reported
Cryptorchidism is a predisposing factor for this type of
productive tumor,
where testicular enlargement is common
Sertoli Cell Tumor
Estrogen production is seen in this type of tumor,
resulting in male dogs that appear attractive to other male dogs,
testicular enlargement, and symmetrical alopecia, with
reduced libido
Sertoli Cell Tumor
Teratomas are rare tumors,
but if seen, are seen in the testes of young _______
horses
Epididymitis due to dilation from sperm accumulation
is known as
Spermatocele
Serous fluid accumulation in the Tunica Vaginalis
Hydrocele
Blood accumulation in the Tunica Vaginalis
Hematocele
Tumors of the Tunica Vaginalis are RARE
except for this type
Mesothelioma
(tumor of the membrane composed of
simple squamous cells that forms the lining of several body cavities)
Multifocal red-brown papules on the scrotal skin
of a ram is caused by this virus
Sheeppox
This is a disease seen most commonly in castrated horses
caused by a granulation response to this bacterial infection
of the scrotum
Scirrhous Cord
The abnormal enlargement of the pampiniform venous plexus (spermatic vein) in the scrotum.
This plexus of veins drains the testicles.
Varicocele
What are the 2 types of neoplastic conditions associated
with the scrotum?
Mast Cell Tumors
Hemangiomas
Which 3 species of animals have all 3 of the following
accessory glands?:
Prostate, Seminal Vesicles, and Bulbourethral Glands
Horse, Cow, Pig
Cats have a prostate and bulbourethral glands.
Dogs lack one of these. Which one?
Dogs only have a prostate,
they lack bulbourethral glands
This is a senile change of the prostate, which can
also occur post-castration. It results in a reduction
of organ size, cell numbers, and acinar structures.
Prostatic Atrophy
This disease of the prostate is very commonly seen
in older intact male dogs, likely due to hormonal imbalances.
Multiple cysts and proliferation of stroma is characteristic.
Prostatic Hyperplasia
A disease of the prostate caused by estrogen, this
condition results in the change of
prostate columnar epithelial cells into squamous cells.
Prostatic METAplasia
What type of neoplasia can result in Prostatic METAplasia?
Sertoli Cell Tumors
Prostatic Neoplasia is RARE, but if seen,
it is seen in old dogs. What type of neoplasia is
typically seen in these cases?
Adenocarcinomas
The connection of the ventral penis to the prepuce,
known as _________ _________
is a developmental disease of the penis seen
most often in bulls
Persistent Frenulum
This developmental disease of the penis
results in failure of closure of the urogenital grooves
Hypospadias
What two circumstances can result in
penile hypoplasia?
Early Castration
Intersex animals
Narrowing of the preputial orifice
preventing protrusion of the penis
Phimosis
Narrowing of the preputial orifice preventing
retraction of an already protruding penis
PARAphimosis
Inflammation of the prepuce
Posthitis
Inflammation of the glans penis
Balanitis
Inflammation of the prepuce and glans penis
balanoposthitis
What are 2 viral causes of balanoposthitis?
BHV-1
EHV-3 (Equine Coital Exanthema)
Balanoposthitis in sheep and cows can be caused
by this bacteria
Corynebacterium spp.
Balanoposthitis can be caused by these two parasites
- Trypanosoma equiperdum*
- Habronemiasis*
Name the 4 kinds of neoplasia that can
occur in the penis or prepuce
Fibropapillomas
SCC
Sarcoids
