Abstract:
The cryoprotective effects of glycerol in three different semen freezing extenders, Tris-citrate (TRIS), TEST, and Tes-Tris-Egg yolk (TTE), on wild-type (WT) rhesus monkey (Macaca mulatta) sperm cryopreservation have been tested. Sperm motility and viability were examined to evaluate the integrity of frozen-thawed sperm, and the best extender was selected to cryopreserve sperm from transgenic Huntington's disease (HD) rhesus monkey. The results showed no post-thaw motility difference among the freezing extender tested (P>0.05). However, sperm membrane integrity in TEST and TTE were significantly better than in TRIS extender (P<0.05). TEST was chosen for HD rhesus monkey sperm cryopreservation. The results showed that post-thawed HD sperm motility and viability was not different compared with WT control group (P>0.05). The present study demonstrates that TEST and TTE were excellent extenders and suitable for rhesus monkey sperm cryopreservation and no detectible differences of post-thaw sperm motility and viability between HD and WT rhesus monkeys resulted from TEST extender.
