Resumen
RESUMEN: En este texto se presenta una revisión de los aspectos básicos relacionados con la formación de radicales libres en el organismo, así como los mecanismos disponibles para hacer frente a un desequilibrio en su producción, fenómeno conocido como estrés oxidativo. El espermatozoide es una célula altamente susceptible al daño inducido por la liberación de radicales libres, ya que su citoplasma es escaso y lo deja desnudo frente a la agresión por radicales libres. Los antioxidantes presentes en el plasma seminal son los encargados de la defensa del espermatozoide frente a un estrés oxidativo, y las enzimas y las vitaminas antioxidantes juegan un papel primordial. El desequilibrio entre la producción de radicales libres y antioxidantes, puede inducir cambios en la fisiología espermática, trastornos de la fecundación y alteraciones de la información genética que posee el espermatozoide. Lo anterior acarrea una serie de trastornos que han sido asociados con infertilidad en el macho.
