A Congenital Short retractor penis muscle

  • Described as a recessive character in Friesians
  • Myectomy of this paired muscle under epidural or local anesthesia at the midway between the anus and the base of the scrotum resulted in improvement.
  • Affected animals are culled due to hereditary reason.

Psychic Impotency Caused by

  • Injury or lesions of the lumbar or scrotal region
  • Phimosis
  • Stenosis of the preputial orifice
  • If a bull is unable to protrude his penis, normally, a careful physical examination of the penis and prepuce should be made.
  • Use of tranquilizers, pudendal nerve blocks or electro ejaculator may be helpful in arriving an accurate diagnosis.

Bulls with short penis should be slaughtered and not used for breeding purposes because of the possible hereditary nature of the defect
