The Relationship Between Endothelial Nitric Oxide Synthase Gene ( <i>NOS3</i> ) Polymorphisms, <i>NOS3</i> Expression, and Varicocele

Abstract

The 4b/a polymorphism may have a protective effect for varicocelem and G894T polymorphism may contribute to varicocele occurrence by lowering the level of NO. The higher NOS3 expression levels in the patient group may be a kind of dilator compensatory mechanism to protect vascular anatomy in varicocele.
