The season of ejaculate collection influenced (P < 0.01) the
sperm quality before freezing (Table 2). The total sperm motility
was greater (P < 0.05) in the ejaculates collected during winter
and spring than in those collected during summer and autumn.
Sperm viability was greater (P < 0.05) in the ejaculates collected
during winter and spring than in those collected during summer.
The ejaculates collected during spring showed the lowest
(P < 0.05) percentages of sperm with abnormal morphology,
whereas those collected during summer showed the highest
(P < 0.05) percentage
