37%. Sperm motility was affected by the
interaction of different conditions, such as SWC, DMAco,
and DMAeq. The combination of high sperm dilution
(1 109
/mL) and low DMAco (6%) was the best condition to
keep high proportion of motile sperm during processing
and after freezing/thawing, whatever the equilibration
time with DMA. In these conditions, the recovery of motile
sperm after cryopreservation was improved to 36% and 39%
using 1 and 30 minutes DMAeq, respectively.
