Effect of dietary vitamin E on the sperm quality of rainbow trout (Onchorynchus mykiss)

Abstract

Vitamin E is a fat-soluble vitamin that consists of a group of tocopherols and tocotrienols with a hydrophobic character. It has a major function in its action as a lipid antioxidant to protect the polyunsaturated membrane lipids against free radical attacks (Wang & Quinn 2000). Vitamin E is a strong antioxidant that is capable of neutralizing reactive oxygen species harming sperm cells during spermatogenesis (Yousef, Abdallah & Kamel 2003). Vitamin E has been used to improve sperm quality and to prevent male infertility both in humans and in animals (Halver 1989
