Differences (mean ± SEM) between the seminal parameters: volume (mL), motility (% of a+b forms), concentration (spermatozoax10⁶/mL). Observed in first ejaculate fraction (FEF), second ejaculate fraction (SEF), and total ejaculate fraction (TEF) in normozoospermic, oligozoospermic, and asthenozoospermic patients; p: statistical significance level between FEF and SEF; P: statistical significance level between FEF and TEF.

Figure 1. Sperm DNA fragmentation. The levels of sperm DNA fragmentation (SDF) were measured by the sperm chromatin decondensation (SCD) assay. The first ejaculate fraction (FEF), total ejaculate fraction (TEF), and second ejaculate fraction (SEF), in normozoospermic, oligozoospermic, and asthenozoospermic patients were compared. SDF presents a similar distribution in all groups, with lower levels in FEF as compared to both SEF and TEF. †p < 0.05; *p < 0.05.
