Oxidative stress in fertility and reproductive performance of females and males mammals

Free radicals are highly reactive oxidation agents, which act as short-lived chemical  intermediates on lipids, amino acids, carbohydrates and nucleic acids. When there is an imbalance and the amount of free radicals exceeds the balance between oxidant production and antioxidant capacity in the cell...

Mamíferos estrés oxidativo fertilidad hembra macho Mammals oxidative stress fertility female male Free radicals are highly reactive oxidation agents, which act as short-lived chemical  intermediates on lipids, amino acids, carbohydrates and nucleic acids. When there is an imbalance and the amount of free radicals exceeds the balance between oxidant production and antioxidant capacity in the cell, a phenomenon known as oxidative stress is generated, which has negative consequences on multiple cellular processes, both in females as in males and therefore negative effect on fertility and reproductive performance. In this work, the oxidative stress in the spermatozoa, plasma membrane, mitochondria, acrosome and DNA is briefly described, as well as the effect of oxidative stress on female and male fertility. Los radicales libres son agentes de oxidación altamente reactivos, que actúan como intermediarios químicos de vida corta sobre lípidos, aminoácidos, carbohidratos y ácidos nucleicos. Cuando ocurren desequilibrios y la cantidad de radicales libres sobrepasa el balance entre la producción oxidante y la capacidad antioxidante en la célula, se genera un fenómeno conocido como estrés oxidativo. Tal anomalía genera consecuencias negativas sobre múltiples procesos celulares de los mamíferos, tanto en las hembras como en los machos, y -por lo tanto- daños en la fertilidad y desempeño reproductivo. En esta revisión se describe brevemente el estrés oxidativo en la membrana plasmática, las mitocondrias, el acrosoma y el ADN de los espermatozoides, así como el efecto del estrés oxidativo sobre la fertilidad de machos y hembras.
