penis is pointed and covered with moist, pink
mucous membrane. The urethra can be identified
towards the tip of the glans on the right side. The external
urethral orifice is a few millimetres caudal to
the tip of the glans penis. Penile warts (viral fibropapillomata)
may be seen on the glans penis (Fig. 11.6).
They often have a narrow neck attached to the glans
penis close to the external urethral orifice. These and
other tumours such as squamous cell carcinoma should
be identified histologically. Tumours may become so
large that the penis cannot be moved through the
preputial orifice. Ulceration of the penile mucosa is seen
in cases of infection, including balanoposthitis (see
under prepuce below).
Bleeding at the time of service may occur from the
penile tumours mentioned above. Bleeding may also
occur from small pinpoint lesions in the erect penis
or arising in the urethra. Their position can seldom
be identified in the non-erect penis.
Penis caudal to the prepuce This can be identified
by palpation through the covering skin and subcutaneous
tissues. It can be readily identified back to the
scrotal neck, and it is in this area that damage to the
tunica albuginea with haematoma formation (‘fractured
penis’) can occur (Fig. 11.7). This type of injury is
more common in younger bulls, especially those
serving young and inexperienced heifers. The dam-
