[ 1 ] - Research Paper: Correlation Between Serum and Seminal Leptin and Nitric Oxide (Nitrite) in Asthenote-ratozoospermic Males

Introduction: Leptin is a critical metabolic signal linking nutrition and reproductive functions. Leptin receptors are expressed in germ cells, Sertoli and Leydig cells. Oxidative stress increases sperm DNA damages. Nitric oxide is a free radical, produced by most cells via Nitric Oxide (NO) synthase and plays stimulatory and inhibitory roles on cells. Physiological concentrations of NO are ess...
