7. 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

8. 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

24. 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

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

26. Phimosis
GOVIND NARAYAN PUROHIT (GNP Sir)

27. 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

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

34. 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)

35. 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.

41. 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

attempts.
