Figure 1 Incidence (%) of total aneuploidy in the fertile control subjects and the patients with oligoasthenoteratozoospermia (OAT) related to the tail swelling pattern. The numbers above the bars indicate the relative increase (+) or decrease (−) compared with the initial nonselected semen (1.00) in the fertile control and OAT men. Statistical significance was analyzed using analysis of variance. Values represent mean ± SD. a–fa vs. b and c vs. d are significantly different at P<.05 between the fertile group and the OAT group; b vs. e, d vs. e, and e vs. f are significantly different at P<.05 in the OAT group.
