Data presented as mean ± standard deviation/median or n (%) unless otherwise noted
TPMSC: total progressive motile sperm count
#Age, progressive motility, and TPMSC were significantly different between DFI groups (p = 0.000)
*Semen volume was significantly different only between DFI < 20% and DFI ≥ 30% groups (p = 0.024)
△Total sperm count was significantly different only between DFI < 20% and DFI ≥ 30% groups (p = 0.001)
◊Sperm concentration of DFI < 20% group was significantly higher than other two groups (p = 0.008 and 0.000, respectively) while no significant difference was indicated between 20% ≤ DFI < 30% and DFI ≥ 30% groups (p = 0.639)
