Estrés oxidativo y antioxidantes en la conservación espermática

Abstract

Oxidative stress of spermatozoa, it refers to damage that may have on the integrity of their structural and physiological components, whose purpose is directly related to the decrease in the survival and fertilizing capacity after he ejaculates. Oxidative stress is caused by the formation of large amounts of reactive oxygen species (ROS), or molecules containing free radicals, which are present during the handling and manipulation of the ejaculate and jeopardize the viability of spermatozoa. The loss of the functionality of sperm-fertilizing capacity, the presence of large amounts of ROS, after he ejaculates, is of great interest and concern on the issue of preservation of seminal male breeding, which aims to maintain, improve and to optimize reproductive efficiency in animal production units, anywhere in the world. This paper presents an overview on oxidative stress, antioxidants, techniques for assessing oxidative stress in spermatozoa and in the end a glossary of terms related to the topic.
