Problems in the reproductive tract may result in difficulty or inability to copulate. Premature penile deviation is an important cause of impotency in male bovines. The aim of the study was to perform clinical and histological evaluation of the correction of surgically induced penile deviation in bulls by fixing the penile apical ligament in the tunica albuginea using synthetic or biological implants. Twenty-one animals with normal penile conformation were subjected to surgical induction of penile deviation by excision of a fragment from the penile apical ligament and replacement with a chitosan slab or polypropylene mesh. The scarification of the tunica albuginea was assessed as a control. The results showed that the tested or evaluated surgical techniques were ineffective in penile deviation correction, since all the animals failed to reestablish the normal axis of the penis. However, microscopic exam revealed that the chitosan slabs proved to be less irritating to the receptor tissue. Therefore, the proposed surgical techniques using synthetic or biological implants were ineffective for the correction of induced penile deviation in bulls.

Los problemas en el tracto reproductivo pueden causar dificultad o incapacidad para copular. La desviación prematura del pene es una causa importante de la impotencia en bovinos machos. El objetivo de este estudio fue realizar una evaluación clínica e histológica de la corrección de la desviación inducida quirúrgicamente en el pene de los toros, mediante la fijación del ligamento apical del pene en la túnica albugínea con implantes sintéticos o biológicos. Veintiún bovinos machos saludables no castrados mestizos, con una libido normal fueron sometidos a la inducción quirúrgica por la extirpación de un fragmento del ligamento apical del pene y su sustitución por una losa de quitosano y una malla de polipropileno después de la confirmación de la desviación del pene. Aunque el examen microscópico reveló que las losas de quitosano han demostrado ser menos irritantes para el tejido receptor. Se observó que todos los animales fallaron en restablecer el eje normal del pene. Por lo tanto, las técnicas quirúrgicas propuestas con implantes sintéticos no eran eficaces para la corrección de la desviación del pene inducida en los toros.
