A Kruskal–Wallis test and a Wilcoxon post hoc analysis were employed for the statistical evaluation. Statistical significance is set at P=0.00625. The letters in superscript indicate statistically significant differences for their respective groups. ^*Statistically significant differences for all other groups. PN: pronuclei; O: oligozoospermia; A: asthenozoospermia; T: teratozoospermia; OA: oligoasthenozoospermia; OT: oligoteratozoospermia; AT: asthenoteratozoospermia; OAT: oligoasthenoteratozoospermia; N: normal semen analysis
