The parameters of sperm motility assessed using CASA are presented in Fig. 1. The MOT value at 3 h after thawing in the PFM treatment group was higher than in the mMS group (P < 0.05), but was not significantly different between treatments at 0.5, 1.5 and 6 h. The PROG, LIN, STR and VSL values in the PFM group were higher than those in the mMS group throughout the 6 h (P < 0.05). The VCL and ALH values in the PFM group were lower than those in the mMS group from 0.5 to 3 h after thawing (P < 0.05). The VAP value in the PFM group was lower at 0.5 h and higher at 3 h than in them MS group (P < 0.05), respectively. The BCF at 1.5 h in the PFM group was lower than in the mMS group (P < 0.05).
