WebApr 13, 2024 · The protection of human sperm during cryopreservation is of great importance to infertility. Recent studies have shown that this area is still a long way from its ultimate aim of maintaining the maximum viability of sperm in cryopreservation. The present study used trehalose and gentiobiose to prepare the human sperm freezing medium … Webpercentage of sperm with slow motility (41.7 ± 4.45%). Independently of the applied thawing rate, the freezing rate generated the main significant effect on total motility. Conclusions. It is possible to conclude that the interaction effect between freezing and thawing rates is nil (except for slow motility) during cryopreservation process.
WebMar 1, 2011 · SUMMARY This study was designed to compare the effect of straw size (0.25 vs. 0.5 ml) and thawing time (30 vs. 60 sec) on the quality of cryopreserved buffalo bull semen. Sperm motility, plasma membrane integrity and viability were higher (p≤ 0.05) in 0.25 ml than 0.5 ml straw, thawed at 37°C either for 30 or 60 sec. WebThe first sperm evaluation was conducted immediately in order to know whether sperm quality was adequate for cryopreservation, taking total and rapid motility (%) as a …
