Correlation of relative STL with age, BMI, DFI, percentage of sperm with immature chromatin, and intracellular ROS levels in normal-weight patients. A There was no correlation between relative STL and age (P = 0.7086). B There was no correlation between relative STL and BMI (P = 0.2715). C STL was negatively correlated with DFI (P = 0.0023). D There was no correlation between relative STL and percentage of sperm with immature chromatin (P = 0.0573). E STL was negatively correlated with intracellular ROS levels (P = 0.0034). F The heat map representation of the correlation matrix with the precise r and p values for each of the parameters. Pearson’s correlation coefficient was used to examine the correlations between STL and selected parameters. p < 0.05 was regarded to be statistically significant. Abbreviations: STL Sperm Telomere Length, BMI Body Mass Index, DFI DNA Fragmentation Index, ROS Reactive Oxygen Species, MFI Mean Fluorescence Intensity
