Changes in viability status associated with chromosomal constitution over a 3-day observation period.

<p>(<b>A</b>) Frequencies of live spermatozoa (blue line) and live aneuploidy (red line). Statistical significance was analyzed using analysis of variance. The data were expressed as the mean frequency of spermatozoa ± SEM. ^A–BViability of euploid spermatozoa and aneuploidy spermatozoa (^a–b) denote significant differences in live frequencies at the indicated time point (<i>p</i><0.05). (<b>B</b>) Frequency of aneuploidy related to tail swelling pattern. The data are expressed as the mean frequency of spermatozoa ± SEM. ^*Spermatozoa with the tail-tip swelling pattern displayed a significantly lower frequency of aneuploidy compared with that in spermatozoa with other patterns at the indicated time point (<i>p</i><0.05).
