The Effect of Cushioned Centrifugation, with and without Enzymatic Reduction of Viscosity, on the Motility Pattern and Kinematic Parameters of Dromedary Camel Bull Spermatozoa. Animals (Basel) 2023; 13:2685. [PMID: 37684949 PMCID: PMC10487258 DOI: 10.3390/ani13172685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 07/20/2023] [Accepted: 07/24/2023] [Indexed: 09/10/2023] Open
Abstract
In order to contribute to the development of semen processing procedures in camelids, the aims of the present study were to evaluate (i) the effect of 35% seminal plasma incubation on dromedary camel epididymal sperm motility and kinematic parameters, (ii) the effects of centrifugation, with cushion fluid and enzymatic reduction of viscosity (Papain + E64) during ejaculate processing, on the motility and kinematic parameters of dromedary camel ejaculates. The incubation with seminal plasma significantly reduced the percentage of progressively motile spermatozoa as well as the proportion of medium progressive spermatozoa whilst increasing the percentage of non-progressive spermatozoa. The centrifugation procedure improved the sperms' kinematic parameters, and the highest values were observed for samples centrifugated with cushion fluid. The samples treated with Papain + E64 showed a significant increase in both total and medium progressive spermatozoa, along with a reduction of non-progressive spermatozoa (p < 0.05). The results of this investigation show that a simple, cheap, and effective procedure, such as cushioned centrifugation, could improve the motility patterns of dromedary camel spermatozoa; in combination with enzymatic reduction of viscosity, this method leads to the best results in terms of recovery rates and sperms' kinematic parameters.

Abstract
Some bulls with apparently normal semen quality yield unacceptably low pregnancy rates. We hypothesised that a differential uterine immunological response to sperm from high and low fertility bulls may contribute to these differences. The experimental model used was heifer follicular phase uterine explants incubated with frozen-thawed sperm from high and low fertility bulls (3-5 replicates per experiment). Inflammatory gene expression of IL1A, IL1B, IL6, TNFA and CXCL8 were assessed by qPCR and IL1-β and IL-8 were quantified in explant supernatants by ELISA. Neutrophil binding affinity to sperm from high and low fertility bulls was also assessed. There was a significant up-regulation of IL1A, IL1B and TNFA from frozen-thawed sperm, irrespective of fertility status, compared to the unstimulated control. This response was confirmed at the protein level, with an increase of IL-1β and IL-8 protein concentrations by 5 and 2.7 fold, respectively (P < 0.05). Although no significant differences in the inflammatory response at the gene or protein level were evident between high and low fertility bulls, more sperm from low compared to high fertility bulls bound to neutrophils (P < 0.05). Using bulls of unknown fertility, cauda epididymal sperm (CES) plus seminal plasma (SP) upregulated IL6 (P < 0.05) but there was no upregulation of any inflammatory gene expression for CES alone. Overall, this ex vivo study demonstrated an upregulation of inflammatory gene expression in the uterus in response to frozen-thawed bull sperm. While there was no difference between sperm from high and low fertility bulls, there was a greater binding affinity of low fertility sperm by neutrophils.

Is addition or removal of seminal plasma able to compensate for the dilution effect of buffalo semen? Andrologia 2021; 53:e14123.

Abstract
The present study aimed to compensate dilution effect using additional seminal plasma (SP) in conventional (80 million (M) spermatozoa/ml) dose and low spermatozoa/dose (8M spermatozoa/ml). We also attempted to confirm whether removal of SP before the extension of ejaculates affects post-thaw sperm quality of buffalo semen. For this, semen ejaculates (N = 15) were divided into four groups: control (CON), removal of SP by centrifugation (NSP), resuspension of the centrifuged semen pellet into SP (CEN) and extra supplementation of SP (ESP). All groups were diluted into two different semen doses to 20 and 2M spermatozoa/0.25 ml using tris egg yolk extender and subsequently cryopreserved. We found that neither addition nor removal of SP affected sperm motility, kinematics, longevity, mitochondrial superoxide production and high mitochondrial membrane potential (MMP). Further, the addition or removal of SP was not able to compensate dilution effect in 2M groups resulting in a significantly (p < .05) reduction in sperm motility, kinematics, sperm longevity, membrane integrity, MMP, and an increase production of mitochondrial superoxide. In conclusion, it appears that role of SP in the sperm cryopreservation process is insignificant.

Abstract
In species where semen is deposited in the vagina, the cervix has the unique function of facilitating progress of spermatozoa towards the site of fertilisation while also preventing the ascending influx of pathogens from the vagina. For the majority of species, advances in assisted reproduction techniques facilitate the bypassing of the cervix and therefore its effect on the transit of processed spermatozoa has been largely overlooked. The exception is in sheep, as it is currently not possible to traverse the ovine cervix with an inseminating catheter due to its complex anatomy, and semen must be deposited at the external cervical os. This results in unacceptably low pregnancy rates when frozen-thawed or liquid stored (>24 h) semen is inseminated. The objective of this review is to discuss the biological mechanisms which regulate cervical sperm selection. We assess the effects of endogenous and exogenous hormones on cervical mucus composition and discuss how increased mucus production and flow during oestrus stimulates sperm rheotaxis along the crypts and folds of the cervix. Emerging results shedding light on the sperm-cervical mucus interaction as well as the dialogue between spermatozoa and the innate immune system are outlined. Finally, ewe breed differences in cervical function and the impact of semen processing on the success of fertilisation, as well as the most fruitful avenues of further investigation in this area are proposed.

Abstract
Artificial insemination (AI) is widely used for livestock breeding. Although sperm cryopreservation is the most efficient method for long-term storage, its use for porcine AI is marginal, because of its dramatic impact on sperm quality. While the removal of seminal plasma is a routine practice prior to porcine sperm cryopreservation, its beneficial role on sperm function has not been investigated in as much detail. In this context and despite seminal plasma being regarded as a mere vehicle of sperm, mounting evidence indicates that it could be positive for porcine sperm fertility. In effect, not only is seminal plasma able to interact with the female reproductive tract after mounting/insemination, but it has been demonstrated it modulates sperm function. For this reason, the composition of this fluid and its proteome have begun to be investigated in order to elucidate whether its components play any role in sperm function, fertility and cryotolerance. Previous research has demonstrated that seminal plasma may maintain the quality and fertilizing ability of frozen-thawed boar spermatozoa when added before or after cryopreservation. However, a large variety of results have been reported with both beneficial and detrimental effects, including studies in which no influence has been observed. This review examines the composition of porcine seminal plasma and summarizes the available published studies regarding seminal plasma supplementation to spermatozoa before or after freeze-thawing. The take-home message of this article is that clearing up the role of seminal plasma in sperm cryotolerance may increase the reproductive performance of frozen-thawed boar spermatozoa.

Abstract
SummaryThe aim of this study was to investigate the effect of adding homologous or heterologous bovine seminal plasma (SP) to SP-free sperm samples before freezing on sperm quality after thawing. Ejaculates from bulls of known fertility were used as a source of SP. The SP was removed from further aliquots of the same ejaculates by colloid centrifugation to create SP-free sperm samples; the resuspended sperm pellets were treated with homologous or heterologous SP from high or low fertility bulls at 0%, 1% or 5% before freezing. After thawing, sperm quality was evaluated by computer-assisted sperm analysis and flow cytometry for membrane integrity, reactive oxygen species, chromatin structure, mitochondrial membrane potential and protein tyrosine phosphorylation. Data were analysed using Proc MIXED, SAS®. Post-hoc comparisons were adjusted for multiplicity using Tukey's method. The addition of SP resulted in significant differences in sperm quality, namely velocity class A, Velocity Straight Line (VSL), Velocity Average Path (VAP), Velocity Curved Line (VCL), Amplitude of Lateral Head Displacement (ALH), Hyperactive (HYP), reactive oxygen species (ROS) production and % DNA fragmentation index (DFI) (P<0.05 for each). Although adding 5% homologous SP from high fertility bulls was beneficial to sperm kinematics, 5% heterologous SP from high fertility bulls had a deleterious effect on chromatin integrity and on sperm velocity. In conclusion, adding SP may have either a beneficial effect or a deleterious effect depending on the individuals involved. It might be feasible to use this method to improve sperm quality in some circumstances.
