Folate and human reproduction
TL;DR: This review focuses on the relation between various outcomes of human reproduction and folate nutrition and metabolism, homocysteine metabolism, and polymorphisms of genes that encode folate-related enzymes or proteins, and identifies issues for future research.

The role of sperm oxidative stress in male infertility and the significance of oral antioxidant therapy
TL;DR: Adequately powered, placebo-controlled comprehensive clinical trials are now required to establish a clear role for antioxidants in the prevention of oxidative stress in the male germ line, such that the clinical utility of this form of therapy becomes established once and for all.
