    PURPOSE: This study was conducted in order to investigate the effects of reactive oxygen species (ROS) levels on the seminal plasma (SP) metabolite milieu and sperm dysfunction.

    METHODS: Semen specimens of 151 normozoospermic men were analyzed for ROS by chemiluminescence and classified according to seminal ROS levels [in relative light units (RLU)/s/106 sperm]: group 1 (n = 39): low (ROS sperm DNA fragmentation index (DFI), chromatin maturation index (CMI), H19-Igf2 methylation status, and untargeted seminal metabolic profiling using nuclear magnetic resonance spectroscopy (1H-NMR), was carried out.

    RESULT(S): The methylation status of H19 and Igf2 was significantly different in specimens with high ROS (P sperm motility (P sperm concentration (P sperm motility (r = - 0.20, P sperm viability (r = - 0.23, P sperm concentration (r = - 0.30, P
