Our results show a higher
sensitivity of chicken sperm to DMAco and DMAeq. In fact,
sperm viability was already decreased after 30 minutes
equilibration even if lower DMAco were used, 0.69 M (6%)
and 1.03 M (9%), and only the 0.69-M DMA preserved the
highest proportion of motile sperm during freezing/thawing.
These results suggest a specific toxic effect of the
cryoprotectant on motile function
