Freeze-thawing as the factor of spontaneous activation of spermatozoa motility in common carp (Cyprinus carpio L.)

Original language description

In the present study, we investigated the possibility of spontaneous carp spermatozoa activation by freeze-thawing. To evaluate this, the parameters of spermatozoa motility percentage, velocity, ATP content level and fertility rate of sperm were used. The motility and velocity of spermatozoa activated by freeze-thawing were characterized by motile spermatozoa with a median value of 16% and a velocity of 98 mu m/s. In addition, the motility and velocity of sperm from the thawed samples were significantlylower than in the control (median value of 100% for sperm motility and 175 mu m/s for sperm velocity). Furthermore, a spontaneously activated spermatozoa motility terminated within five minutes post-thaw time. After freeze-thawing the ATP level significantly decreased with post-thaw time (46 nmol ATP/10(9) and 10 nmol ATP/10(9) at 25 s and 10 min after thawing, respectively). Fertility of spermatozoa, was not significantly affected within 10 min post-thaw. On the other hand, the fertili
