Penis is the copulatory organ of male. It is almost cylindrical in shape. The terminal portion of penis which is freely moving within the sheath is called as prepuce.
Penis of the bull should be examined for indications of injury or diseases.
Penis can be manually exteriorized, but in most cases should be examined at the time of collection of semen sample.
Penile deviations can be evaluated accurately only when the male mounts a teaser animal or breeds a female.
Electro ejaculator stimulation often produces deviations or other abnormal configurations in the normal penis so these defects must be evaluated by observing natural mating.
Persistent frenulum, tumors, abscess, balano-posthitis etc should be ruled out.
