Effect of Honey, Coenzyme Q10, and β-Carotene/α-Tocopherol as Novel Additives in Rabbit-Sperm Cryopreservation Extender. Animals (Basel) 2023; 13:2392. [PMID: 37508170 PMCID: PMC10376550 DOI: 10.3390/ani13142392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 06/22/2023] [Accepted: 07/21/2023] [Indexed: 07/30/2023] Open
Abstract
The effectiveness of rabbit-sperm cryopreservation is still below average compared to other domestic species. After the sperm cryopreservation process, post-thawing parameters like motility and membrane integrity are significantly compromised. The use of new extender constituents is an approach that can be used to improve the effectiveness of cryopreservation. Accordingly, we used honey (1.25, 2.5, 5, and 10%), coenzyme Q10 (100 and 200 μM), and β-carotene/α-tocopherol (500 μM/620 μM and 250 μM/310 μM) as candidate components for rabbit-sperm extenders during cryopreservation. Ejaculates from commercial adult rabbit bucks (n = 5) were cryopreserved using conventional freezing. Several post-thawing sperm parameters were assessed, including total motility, membrane integrity, viability, nuclear membrane integrity, acrosome reaction, and mitochondrial membrane potential and activation. Additionally, we performed hormonal analyses of the seminal plasma. Moreover, we analyzed the post-thawing levels of a molecular marker of sperm quality, proAKAP4, which was used in rabbits for the first time. Our findings showed that the 2.5% honey supplementation increased the post-thawing sperm motility (13.75 ± 3.75%) compared to the greater concentrations employed. However, the post-thawing motility was negatively affected by the coenzyme Q10 (0%, in both groups) but was not affected by the β-carotene/α-tocopherol supplementation (22 ± 18.15%, and 11.67 ± 10.17%). In conclusion, the cryopreservation protocols of this study did not help to maintain the sperm parameters after thawing. Further studies are required to identify novel protocols to mitigate the damage caused to rabbit sperm during cryopreservation.

Abstract
In the present study, we evaluated the sustaining effect of various glutathione (GSH) concentrations in extender on rabbit sperm attributes during storage at 5°C for 24 h. Semen was collected from regular donor rabbit bucks using an artificial vagina and initially evaluated for sperm quality. The qualifying ejaculates were diluted with one of the extenders having 0, 1, 2, 4 or 8 mM GSH, to achieve a final concentration of 1×108 sperm/mL. The extended samples were stored at 5°C for 24 h. Sperm motility, motion kinetics, acrosome integrity and viability were assessed after 3, 6, 12 and 24 h of storage. The results showed that total sperm motility and sperm motion kinetics (oscillation index of the sperm, straightness index and beat cross frequency) were influenced (<em>P</em><0.05) by glutathione dose and refrigeration time. An interaction of (<em>P</em><0.05) GSH concentrations and refrigeration time was observed for sperm viability and acrosome reaction rate. In conclusion, the 4 mM GSH supplemented extender’s protective influence was remarkable to maintainrabbit sperm quality for 24 h 5°C.

Abstract
<p>The present study aimed to evaluate the effect of supplementation of INRA-82 semen extender with different cryoprotectants (dimethyl sulphoxide; DMSO vs. dimethyl formamide; DMF) on the quality of white New Zealand rabbit buck spermatozoa. We also investigated the possible association between the synergistic action of DMSO and DMF and their relation with INRA-82 extender composition. Semen was collected and pooled from 8 adult rabbit bucks. Pooled semen samples were diluted 1:1 with INRA-82 extender supplemented with DMSO 8%, DMF 8% or a combination of DMSO 4% and DMF 4%. The diluted semen samples were cryopreserved in 0.25 plastic straws. After thawing, progressive motility, sperm viability, sperm abnormalities, membrane integrity, acrosome status, viability index and DNA integrity were evaluated. The results showed that dilution of rabbit buck semen in INRA-82 supplemented with DMSO and DMF (4% each) before freezing significantly (<em>P</em><0.05) improved sperm motility (42.00%), percentage of live spermatozoa (45.30%), proportions of spermatozoa with intact acrosome (59.75%) and percentage of spermatozoa with non-fragmented DNA (86.04%), compared to those diluted in INRA-82 supplemented either with DMSO 8% (+9, +10, +5 and +7 percentage points, respectively) or with DMF 8% alone (+18 +18, +12 and +9 percentage points, respectively). In conclusion, dilution of rabbit buck semen before freezing with INRA-82 extender supplemented with a combination of DMSO 4% and DMF 4% improved quality of frozen-thawed New Zealand White rabbit spermatozoa. Furthermore, our results also suggest that supplementation of INRA-82 with DMSO or with DMF alone at higher concentrations deteriorates the sperm quality.</p>
