Improvement Prospects of Lycopene Supplementation in the L-NAME Toxicity on the Male Wistar Rat Reproductive System

Abstract

Non-selective nitric oxide synthase inhibitors, such as N (G)-nitro-L-arginine Methyl Ester (L-NAME), are typically prescribed to treat spinal injuries and hypotension. Many physiological processes, including the regulation of reproductive hormones, are ty pically linked to it. Bioactivity in physiological systems is influenced by the antioxidant lycopene. This study sought to determine the imp act of lycopene supplementation and L-NAME administration on gonadal hormones and sperm parameters. Twenty male Wistar rats were used for this study and were divided into four groups containing 5 rats each. L-NAME (5mg/kg) was administered through drinking water and Lycopene (5mg/kg) was supplemented through oral gavage for four weeks. Using established protocols with Elisa Kits, plasma hormone levels were ascertained. Estradiol did not differ substantially across all groups, however, the group that received L-NAME had lower plasma concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and nitric oxide (NO). Lycopene supplements raised testosterone, FSH, LH, and NO levels while not affecting estradiol. The sperm profile was altered with L-NAME but ameliorated in Lycopene supplementation. We conclude that lycopene has the potential to protect against hormonal imbalance and male infertility resulting from Nitric oxide synthase (NOS) inhibition.
