Representative sperm tracks in the three main clusters (a) and distribution of spermatozoa with cytoplasmic droplet (CD) or bent tail compared to sperm with normal tail morphology (normal sperm) in nine kinematic clusters (b). Data are based on sperm tracks analysed after a 30-min incubation period at 38 °C in Beltsville Thawing Solution from extended semen samples (n = 10 boars) with enhanced prevalence (≥ 15%) of cytoplasmic droplets or bent tails. Only clusters containing at least 5% of sperm in any of the sperm subsets were considered for evaluation. Cramer’s V (range from 0 to 1) indicates the effect size of a certain morphological defect on sperm distribution to the different cluster (movement patterns). V < 0.1 = no effect; 0.1 ≤ V < 0.3 small effect; 0.3 ≤ V < 0.5 moderate effect; V ≥ 0.5 = large effect.
