The document discusses infertility in male domestic animals. It begins by defining infertility as a temporary loss of fertility characterized by a reduced number of viable sperm. It then describes Nils Lagerlof's classification of infertility which includes impotentia coeundi (inability to copulate), impotentia generandi (inability to fertilize), and miscellaneous forms. The majority of the document provides details on causes, diagnosis, and treatment of various conditions that can cause impotentia coeundi such as injuries, diseases of the penis/prepuce, environmental factors, and more. It focuses on conditions like low sex drive, inflammation, tumors, deviations and injuries of the penis.

7. Prognosis for low sex drive Guarded to poor
Low sex drive is inherent in some Bos indicus bulls
• 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

10. Joint , Muscle, Bone, Tendon and Nerve injuries
Joint Ligament
1.Coxitis
Inflammation of hip joint
It is common in dogs and boars
Characterized by a short stride and adduction
of the limb.
2. Gonitis

Common in bulls
Characterized by a short, stiff gait, distension
and enlargement of joint capsule of the stifle.
1.Round ligament
Rupture of round ligament may be observed in
bulls with degenerative coxitis.

Rupture of the anterior cruciate ligament of the
stifle inhibits mounting in bulls and dogs.

15. Persistent Penile Frenulum
• It is characterized by a fibrous band attaching the prepuce to the free portion of the
penis.
• At approximately 4 months, the penis and prepuce begin to separate under the
influence of male hormones. Separation should be complete by 8 to 11 months of
age.
• The frenulum normally ruptures during separation of the penis from the prepuce
• Symptoms: Ventral deviation of the penis during attempts at coitus.
• Treatable by myectomy

24. Treatment and Prognosis
Douching the prepuce with antiseptics (1:2000 acriflavin or potassium permanganate
solution, 1% H2O2 solution) .
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
Stenosis of the prepucial orifice
Inability to protrude the penis outside the sheath or prepuce is called phimosis.
Cause
Pendulous sheath,
Chronic prolapse of the prepuce - posthitis – phimosis
Due to injuries, wounds and infections
Some time congenital also (dog, cat and horse)
Treatment
Surgical operation.

27. Paraphimosis
The inability to withdraw the penis into the prepuce called as paraphimosis
Paraphimosis – Swelling – Oedema - Balanoposthitis
Cause
Paralysis of the penis
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.

30. Phallocampsis or Deviations of the penis:
Ventral or Rainbow deviation
Dorsal ligament is thin and stretched to the point that it is incapable of holding up
the distal portion of the penis during erection.
Lateral deviation of penis
It may occur due to secondary to trauma of the penis or prepuce. Scars or adhesions
of the elastic tissue pull the penis to one side or the other.
GOVIND
NARAYAN
PUROHIT
(GNP
Sir)
32. Spiral or Corkscrew Penis
Dueto dorsal apical ligament slipping off to the left hand side of the penis
resulting in a counter clockwise spiral as viewed from the rear.
Spiraling of the tip of the penis is a normal part of the process of ejaculation in
the bull, occurring after intromission, during the ejaculatory.
It is not considered pathologic until its occurrence is observed on repeated
natural breeding trials in which it occurs prior to entrance into the vulva and thereby
prevents intromission.
GOVIND
NARAYAN
PUROHIT
(GNP
Sir)
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.

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 the prepuce to the abdominal wall or to the
skin.
Those both are produces more severe phimosis.
Surgical treatment - More severe form of adhesion.

Balanced Diet
Exercise
Age Too young -- No experience
Too old animals -- Decline
testosterone
Young males patiently, quietly trained and
handled.

Para tuberculosis,
Severe internal parasitosis etc.
Prevention
Proper deworming
Proper vaccination
Hormonal
Causes

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
or when the penis is thrust against the escutcheon of the cow during breeding
attempts.

43. Preputial Avulsion
Preputial avulsion usually occurs during semen collection with an artificial vagina
(AV).
If the AV is too tight, a transverse or oblique laceration may occur at the dorsum of
the preputial ring or fornix.
