From: The effects of male age on sperm analysis by motile sperm organelle morphology examination (MSOME)
Percentage of spermatozoa with large nuclear vacuoles (presence of one or more vacuoles occupying > 50% of the nuclear area) by MSOME according to age for the three age groups. There was no difference in the percentages of spermatozoa with large nuclear vacuoles in the younger (I and II) groups (P = 0.39, Mann-Whitney U test). The percentage of spermatozoa with large nuclear vacuoles in the older group (III) was significantly lower than those in the younger (I and II) groups (P = 0.0005 and P = 0.021, Mann-Whitney U test).
