Title

Research Paper: Correlation Between Serum andSeminal Leptin and Nitric Oxide (Nitrite) in AsthenoteratozoospermicMales

Pages

  107-114

Abstract

 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 increasessperm 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 concentrationsof NO are essential for the biology and physiology systems. However, a low level of NO has adetrimental effect on cells. This study aimed to determine the correlation between seminal andSerum leptin and NO in asthenoteratozoospermic men. Methods: Semen and blood samples were obtained from (n=52) males referring to the Arak infertilityClinic, in Arak City, Iran. We examined each patient for serum hormones (LH, testosterone) bychemiluminescence. Serum and Seminal leptin were measured by ELISA and seminal NO wasmeasured by Griess reaction. Results: There were differences in Serum leptin levels, and total testosterone, LH, and NO concentrationsamong the 2 groups. Asthenoteratozoospermic groups showed higher testosterone and LH levelsthan the normozoospermic group. Serum leptin levels of asthenoteratozoospermic men significantlyincreased in comparison with normozoospermic men. Seminal leptin levels of asthenoteratozoospermicmen significantly decreased compared to normozoospermic men. NO levels in asthenoteratozoospermicmen significantly decreased in comparison with normozoospermic cases. There were no significantcorrelations between serum and Seminal leptin and seminal plasma NO. Conclusion: Our results do not support the hypothesis that in vivo serum and Seminal leptin affect NOsynthesis. Also, our results revealed that nitrite in the seminal plasma is not able to entirely indicate invivo NO synthesis.
