Dietary fatty acids affect semen quality: a review
Mammalian spermatozoa are characterized by a high proportion of polyunsaturated fatty acids (PUFA) which play a crucial role in
fertilization. This review focuses on analysis of sperm fatty acid profiles and the effects of omega-3, saturated and trans dietary and
sperm fatty acids on sperm parameters. Two major points have been pivotal points of investigation in the field of sperm fatty acid
profiles: first, the comparison between fatty acid profiles of fertile and infertile men and second, the effect of dietary fatty acids on
sperm ...

Antioxidants and Polyphenols: Concentrations and Relation to Male Infertility and Treatment Success
Oxidative stress is induced by reactive oxygen substances (ROS) that are known to affect male fertility.The aims of this study were
to prospectively investigate and characterize total antioxidant and specifically polyphenols concentrations and their relations to
sperm quality and fertility treatment success. During their infertility treatment, sixty-seven males were prospectively recruited
to this study. After separation of the sperm from the semen sample, the semen fluid samples antioxi...

Antioxidant supplements and semen parameters: An evidence based review
Many studies have focused on male infertility. There is limited evidence about the influence of nutrition on quality of semen. Approximately, 30-80% of infertility cases are caused by oxidative stress and decreased level of seminal total antioxidant capacity. This study was aimed to review the effects of oral antioxidant supplements on improving major semen parameters such as sperm concentration, motility, morphology, DNA damage, and fertility rate. Data were extracted from PubMed and Google scholar database by using the ...
