MiscellaneousEnvironmental
GOVIND NARAYAN PUROHIT (GNP Sir)

Prognosis for low sex drive Guarded to poor
Low sex drive is inherent in some Bosindicusbulls
•Therapy
Before therapy careful examination and diagnosis is necessary
i)Diseases/deficiencies should be treated accordingly
ii)Regular exercise
iii)Decreasing sexual load
iv)Proper handling and management
GOVIND NARAYAN PUROHIT (GNP Sir)

Libido enhancement
•Testosterone Injections Bull and stallion 100-500 mg IM or SC
at weekly intervals
•Boar and Ram 50-100 mg, Dog 10-50 mg
•Chorionic gonadotropin
Bull/Stallion 5000-10000 IU IM or SC at 15-30 days
Dogs 100-500 IU IM or SC

•“Pizzlerot” or "Sheath rot" .
•CorynebacteriumrenaleRam
•Dourine
•TrypanosomaequiperdumStallion
GOVIND NARAYAN PUROHIT (GNP Sir)

Treatment and Prognosis
Douching the prepuce with antiseptics (1:2000acriflavinor potassium permanganate
solution, 1% H
2O
2solution) .
Application of oily preparation of antiseptics and antibiotics are also helpful.
Systemic antibiotics given in severe cases and sexual rest require during treatment.
Prognosis
Good in mild cases
Guarded in chronic cases

Phimosis
Stenosisoftheprepucialorifice
Inabilitytoprotrudethepenisoutsidethesheathorprepuceiscalledphimosis.
Cause
Penduloussheath,
Chronicprolapseoftheprepuce-posthitis–phimosis
Duetoinjuries,woundsandinfections
Sometimecongenitalalso(dog,catandhorse)
Treatment
Surgicaloperation.
GOVIND NARAYAN PUROHIT (GNP Sir)

Phimosis
GOVIND NARAYAN PUROHIT (GNP Sir)

Paraphimosis
The inability to withdraw thepenisinto theprepucecalled as paraphimosis
Paraphimosis–Swelling –Oedema-Balanoposthitis
Cause
Paralysis of thepenis
Bulls -Rabies
Horses -Late stages of dourine.
Most common in the dog and stallion

Priapism
Persistent erection in absence of sexual stimulation occurs most often in dogs.
Penile amputation is only feasible treatment.

Spiral or Corkscrew Penis
GOVIND NARAYAN PUROHIT (GNP Sir)

S-shaped deviation
 This mainly due to when the apical ligament is sufficient in strength but
insufficient in length and the S-shape results during erection.
GOVIND NARAYAN PUROHIT (GNP Sir)

Adhesions in the Penis and Prepuce
Adhesion in the region of sigmoid flexure may be due to horn injuries in bull and
ram.
An adhesion in the region of fornix of theprepuceto the abdominal wall or to the
skin.
Those both are produces more severe phimosis.
Surgical treatment -More severe form of adhesion.

Miscellaneous
Causes
GOVIND NARAYAN PUROHIT (GNP Sir)

Hematoma of the penis
Hematoma of the penis is also referred to as "ruptured penis", "broken penis" or
"fractured penis" -
Common in bovine species and rare in others -
Occurs during coitus when the cow slips or goes down under the weight of the bull
or when the penis is thrust against the escutcheon of the cow during breeding
attempts.
