Cryosurvival of human spermatozoa frozen in eight different buffer systems
human spermatozoa eight different buffer systems
2009/2/23
The present study was conducted to ascertain optimal cryoconditions for human spermatozoa by comparing the relative cryoprotective efficiency of eight buffer systems and assessing various cryovial...
Comparison of glycerol and a zwitter ion buffer system as cryoprotective media for human spermatozoa. Effect on motility, penetration of zona-free hamster oocytes, and acrosin/proacrosin
spermatozoa human cryopreservation
2009/2/20
This study compared the cryoprotective effect of glycerol with that of a zwitter ion buffer system (TESTCY). Spermatozoa that are cryopreserved in the presence of glycerol possess a somewhat highe...
Comparison between human sperm preservation medium and TEST-yolk buffer on protecting chromatin and morphology integrity of human spermatozoa in fertile and subfertile men after freeze-thawing procedure
Acridine orange chromatin normality cryopreservation
2008/12/29
The aim of this study was to identify the detrimental effect of the freeze-thaw process on chromatin integrity and morphology of human spermatozoa, and to determine whether human sperm preservation ...
