Figure 2.

Scatter plots of the variables considered in 49 patients grouped according to assisted reproduction technique (ART) outcome: positive outcome (11 patients) and negative outcome (38 patients). (a) sperm concentration (mL × 10⁶), progressive motility %, normal morphology %, volume (mL) are shown; (b) double stranded DNA %, mature chromatin % and F₂-IsoPs (ng/mL) are reported. The red symbols represent the mean of the values. The group with positive outcomes showed increased double stranded DNA % (b) than that observed in the group with negative outcomes (p = 0.002).
