Table 2 Proportion of males sampled that had at least one sperm in different categories of abnormality, and the mean proportion of sperm per male in each category. All abnormalities are included in the first category; some males had sperm with abnormalities in more than one category
From: Extensive variation in sperm morphology in a frog with no sperm competition
