Sperm/mL: the number of spermatozoa/mL; Mot (%): the percentage of sperm with rapid + slow progressive motility; morphology (%): the percentage of sperm with normal morphology; vitality (%): the percentage of viable cells; FI: fertility index is a number indicating the fertility power of ejaculated sperm—the number of sperm probably is devoid of defects; A (%): the percentage of sperm apoptosis; N (%): the percentage of sperm necrosis; I (%): the percentage of sperm immaturity; F2-IsoP: semen F2-IsoP levels (ng/mL) evaluated by the GC/NICI-MS/MS analysis. values are reported when significant: .
