Figure 1

Morphology of cumulus recovered at different stages of the follicular maturation in the mare. The number of compact and expanded cumulus were illustrated by histograms in each of the 6 follicular maturation stages (early dominance [ED], end of growth [T0 h], 6 h [T6 h], 12 h [T12 h], 24 h [T24 h] and 34 h [T34 h] after injection of crude equine gonadotropin). Cumulus morphology in each group was compared with the non parametric Kruskall Wallis test. ** p < 0.05 at least.
