IZQUIERDO, A. C. et al. Oxidative stress in fertility and reproductive performance of females and males mammals. Rev. vet. [online]. 2020, vol.31, n.1, pp.97-100. ISSN 1669-6840.  http://dx.doi.org/10.30972/vet.3114650.

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.

Palabras clave : mammals; oxidative stress; fertility; female; male.
