Abstract
The addition of dithioerythritol at 0.5 and 2 mM doses led to higher percentages of subjective motility (62.9 ± 4.2% and 63.6 ± 1.8%) compared to control (52.0 ± 4.9%, P < 0.05). As regards CASA motility, dithioerythritol 0.25 and 2 mM (60.2 ± 4.5% and 59.6 ± 1.2%) groups were higher from that of control (44.2 ± 8.7%, P < 0.05). For the CASA progressive motility, 0.25, 0.5 and 2 mM doses of dithioerythritol (22.0 ± 2.1%, 21.7 ± 2.5% and 24.0 ± 1.2%) had increasing effect in comparison to control (15.0 ± 2.5%). Dithioerythritol at 1 and 2 mM doses for ALH provided higher values compared to the control (P < 0.001) following the freeze-thawing process. Supplementation with dithiothreitol did not significantly affect the integrities of sperm membrane and acrosome, and mitochondrial activities. No significant differences were observed in biochemical parameters among the groups (P > 0.05). Findings of this study showed that dithioerythritol supplementation in semen extenders, was of greater benefit to sperm motility of frozen-thawed ram sperm.
