BSE & Male Pathology Flashcards
purpose of BSE
- Estimate reproductive potential
- Identify potentially infertile or subfertile males
- Provide management or treatment recommendations for subfertile males
Indications for BSE
Prior to sale
Following a purchase
Prior to breeding season
Diagnosis of infertility or subfertility
what should a general BSE physical exam include
BCS, general body systems, conformation, heritable defects
BSE PE for Bulls
BCS, pelvic size, weight, eyes, teeth, feet
common hereditary foot problems of bulls
corkscrew claw defect
interdigital fibromas (corns)
weak pasterns
post-leggedness
sickle hocks
common ocular problems of bulls
SCC
infectious bovine KCS/pink eye (Moraxella bovis)
what are the testes evaluated for in the bulls and rams
scrotal circumference
what are the testes evaluated for in the stallion and dog
scrotal width
what can correlate to potential sperm production
size of testes - testicular volume
what is most common abnormal finding in bull internal genitalia
enlargement, excessive firmness or loss of lobulation of vesicular glands (seminal vesicles)
what accessory sex glands do dogs have
prostate
what accessory sex glands do cats have
prostate
bulbourethral
what accessory sex glands do stallions, bulls and rams have
prostate
bulbourethral
ampulla
vesicular glands
what accessory sex glands do pigs have
prostate
bulbourethral
vesicular glands
parts of a BSE
history
animal identification
PE
sexual behavior and mating ability
semen evaluation
classification
what ancillary tests can be used for semen evaluation
sperm chromatin structure assay (SCSA)
anti-sperm antibody test
fluorescent probes
biochem analysis of seminal plasma
true/false
BSE estimates fertility, the true criteria for evaluating fertility is preg rate in females bred
true
what is testicular hypoplasia associated with
congenital/hereditary
chromosomal abnormalities
cryptorchidism
exogenous hormones
where is a left testes located in a cryptorchid, right testes?
left - abdominal
right - inguinal
is unilateral or bilateral cryptorchordism more common? which one is infertile?
unilateral more common
unliteral potentially fertile
bilateral infertile
what is the most frequent cause of reduced fertility
testicular degeneration due to no spermatogenesis
what bacteria causes orchitis
Brucella
name 3 spermatic cord and/or tunic lesions
periorchitis
hydrocele, hematocele
torsion of spermatic cord
what testicular tumor:
tan, discrete, soft
most common testis tumor in dogs
minimal androgen production
seldom metastasize
Leydig cell tumor (interstitial cell tumor)
what testicular tumor:
white, lobular, firm
metastasis unusual
estrogenic effects: feminization, alopecia, bone marrow suppression
sertoli cell tumor
3 types of germ cell tumors
teratoma
dysgerminoma
seminoma
5 types of scrotal lesions
- dermatitis
- trauma
- edema
- frostbite
- neoplasm
prolonged penile swelling w/o stimulation
Priapism
inability to retract penis into prepuce
Paraphimosis
stenosis of preputial orifice preventing protrusion of penis
Phimosis
6 types of bull lesions
penile deviation
infectious pustular balanoposthitis
persistent frenulum
penila hematoma
preputial abscess
fibropapilloma
what virus causes infectious pustular balanoposthitis
BHV-1
6 types of stallion lesions
priapism
paraphimosis
SCC
habronemiasis
coital exanthema
urethritis
what virus causes coital exanthema
EHV-3
3 types of dog lesions
transmissible venereal tumor
canine herpesvirus
fracture of os penis
preputial diverticulitis is a lesion in what species
boars
2 types of lesions in sheep
ulcerative posthitis “pizzle rot” due to C. renale or high protein ration
urolithiasis
what bacteria can cause seminal vesiculitis in bulls and stallions
actinomyces pyogenes
what species is prostatic disease common in
dogs
primary vs secondary sperm defects
primary - defect in spermatogenesis
secondary - defect post testicular (epididymis or environment)
what stain do you use for a sperm viability assay
eosin/nigrosin stain
sperm affected will stain pink/red
why is yellow semen color normal in bulls
riboflavin
