Male Repro Failure 2 Flashcards
primary infection of the penis
balanitis
primary infection of the prepuce
posthitis
infection of the penis and prepuce
balanoposthitis
excessive sheath cleaning may predispose a stallion to ______, only clean every 6 months
balanoposthitis
veneral dz that causes balanoposthitis in the bull
infectious pustular vulvovaginitis virus (BHV-1)
common name for balanoposthitis in the ram
pizzle rot
bacterial cause of balanoposthitis in the ram
corynebacterium renale
tx for balanoposthitis (pizzle rot) in the ram
decrease protein intake, shear underside of ram
high ____ diet predisposes rams to increased urea in the urine, urine scalding, necrosis/blockage of preputial orifice
protein
lack of ability to get penis out of external or internal sheath
phimosis
most common cause of phimosis
persistent penile frenulum
tx for preputial eversion in machos post-breeding
decrease edema, purse string suture, 2 weeks sexual rest
penile swelling that occurs during penile paralysis leads to _______
paraphimosis
cause of penile paralysis
decreased retractor penis m tone (caused by ace, decreased muscle tone, EPM, EHV, spinal cord injury)
signs leading to early dx of penile paralysis
failure of retraction in response to stimulation, inability to retain penis w/in sheath following manual replacement
tx for paraphimosis
hydrotherapy, hydroscopic agents, massage, +/-compression bandage
hydroscopic agents that can be used to tx paraphimosis
glycerol, lanolin
do penile paralysis, paraphimosis and preputial injury typically result in inability to urinate?
no
tx for acute paraphimosis
anti-inflammatories, antimicrobials, hydrotherapy, forced exercise, avoid sexual arousal
duration of paraphimosis prior to tx of
24 hours
tx for adhesions caused by paraphimosis in the bull
preputial resection (reefing)
persistent penile erection in absence of sexual stimulation
priapism
cause of priapism
decreased venous drainage from corpus cavernosus penis
persistent erection and penile protrusion during priapism leads to edema at the _______
preputial reflection
way to tell difference b/t priapism and paraphimosis
palpation (priapism hard, paraphimosis softer)
etiology of priapism in the dog
trauma following mating, especially during tie (distemper, spinal cord lesions, penile thromboembolism, UTI, constipation, idiopathic)
in the dog, will be engorged during priapism and not engorged during chronic paraphimosis
bulbus glandis
tx for priapism in the horse
benztrophine mesylate, penile massage, corpus cavernosum penis irrigation (but usually referral)
tx for priapism in the dog
tx inciting cause, return penis to sheath (many require phallectomy, no efficacious pharamacologic tx)
species that fibropapilloma is most common in
bull
tx for fibropapilloma in the bull
self-cure by 3 years, removal, autogenous vax (good prognosis typically)
fibropapilloma in the stallion often occurs concurrently with ______
balanoposthitis (maybe a precursor to SCC)
most common penile/preputial neoplasm of the stallion/gelding
SCC
tx for SCC in the stallion
cryotherapy, 5-fluorouracil, aldara, sx excision
omission of sperm-rich fraction from ejaculate during semen collection
incomplete ejaculate
alternation b/t sperm-rich and prostatic fractions in young dogs
mixing of fractions
dog achieves but does not mainain intromission, breeding may not result in pregnancy since need to tie for at least 5 minutes
slip mating
damage to sensory innervation of glans penis, dorsal nerve of penis damaged by stretching secondary to paraphimosis, and compression of spinal root by exostoses can all cause ________
ejaculatory failure
