Eighteen 18 to 24-month-old mixed breed bullocks were submitted to removal of the apical ligament of the penis to induce penile deviation. After 60 days from the surgery the steers were put together with cows in heat. A ventral and right lateral penis deviation leading to incapacity to copulate was observed. The bullocks were then submitted to an autolgous transplant of a cartilage segment from the ear pinna placed on top of the tunica albuginea, replacing the penile ligament apical tha had been removed. The implanted material was well tolerated; histologically with only infiltration few mononuclear cells, polymorpho nucleated cells and giant cells, and fibrosis, which caused strong adherence and provided ability to sustain the free penile extremity. The bullocks that were cows in heat did not show any degree of penile deviation nor any change in sexual behavior. The surgical method described here was shown to be satisfactory as to be indicated for correction of ventral and right lateral penile deviation in bullocks. |
