What is it about?
A considerable number of infertile men have no known mechanism for their infertility. This study aims to examine if there is an association between endothelial nitric oxide synthase (eNOS) T-786C, G894T, and 4a/b gene polymorphisms and idiopathic male infertility.

Why is it important?
Worldwide, about one in 10 couples is infertile and around half of this is due to male factors (WHO, 1999). Because the etiology and pathogenesis are still to be defined, a significant proportion of male infertility is considered idiopathic. Through animal studies conducted recently, hundreds of genes have been found to be related to impaired spermatogenesis and reported as possible pathogenic mechanisms for idiopathic male infertility; however, their human counterparts need to be investigated in infertile patients.
