In Vitro Effects

Handling equine semen during the refrigeration process reduces sperm viability, and consequently causes membrane lipid peroxidation, among other challenges. The present study aimed to evaluate the in vitro effects of glutathione (control, 1. 0, 1. 5, and 2. 5 mM) on equine semen in a refrigeration protocol of 16ºC for 36 hours. The following variables were evaluated after 0, 12, 24, and 36 hours refrigeration: total sperm motility, vigor, viability, and plasma and acrosomal membrane integrity. Motility was higher with 2. 5mM of glutathione (57. 8 ± 7. 3) after 12 hours of refrigeration compared to the control (53. 2 ± 8. 3) (P < 0. 05). After 36 hours of refrigeration, motility was higher with 1. 5 mM (43. 4 ± 12. 7) and 2. 5mM glutathione (45. 5 ± 6. 2), than it was with 1mM glutathione (38. 2 ± 9) and the control (35. 5 ± 18. 4) (P < 0. 05), respectively. Vigor was highest with 1. 5mM glutathione (3. 7 ± 0. 3) after 36 hours compared to the control (3. 2 ± 1. 1), (P < 0. 05). Viability differed between control and 1mM treatments (79. 5 ± 1. 8) only after 24 hours (75. 5 ± 9. 7) (P < 0. 05). Throughout the investigation, no significant differences were noted in plasma and acrosomal membrane integrity (P > 0. 05). The 1. 5 and 2. 5mM glutathione levels were more efficient in protecting sperm cells and yielded higher total motility values after 36 hours of refrigeration.

Fresh Semen

Boars having normal (71.1 ± 1.2%; n = 10) or low (35.12 &plusmn 3.9%; n = 10) sperm motility 24 h after collection were used, and semen was evaluated following storage in Beltsville Thawing Solution (BTS) for 24 h at 18°C. Sperm lipids were extracted and lipid peroxidation quantified. No differences were evident in fresh semen, but after 24 h, sperm motility, viability and membrane permeability in the low motility group were lower (P < 0.001) compared with the normal motility group. Sperm membrane lipid peroxidation was greater (P < 0.001) in the low motility group. A factor influencing sperm storability is membrane lipid peroxidation, which can be accurately assayed using a commercial kit.Key words: Boars, sperm motility, sperm quality, lipid peroxidation
