Abstract
Propidium iodide (PI) and YO-PRO-1 (YPI) dyes are routinely used to determine sperm viability in many livestock species. It is commonly accepted that these dyes penetrate only sperm cells with damaged plasma membranes. Recently, however, the mechanism of dye uptake unrelated to damaged plasma membranes, but instead related to pannexin channels in dog and stallion sperm cells was demonstrated. This pilot study aimed to evaluate the role of pannexins in the uptake of PI and YPI dyes on Wallachian frozen-thawed ram spermatozoa by flow cytometry using probenecid, a specific inhibitor of pannexin channels. Additionally, the expression of pannexins in Wallachian sperm was evaluated directly (by qRT-PCR). The results demonstrate the active role of pannexin channels in the uptake of PI and YPI dyes on frozen-thawed Wallachian ram sperm. In conclusion, when using the PI or YPI exclusion assay to determine Wallachian frozen-thawed ram sperm viability, the danger of overestimating the number of spermatozoa with the damaged plasma membrane must be considered. The observed breed-specific, and more importantly, individual differences in gene expression as well as in dye uptake indicate the need for further studies.

Abstract
Abstract Searching for improvements in semen cryopreservation, natural substances are commonly studied focusing to improve the sperm quality. The aim of this study were evaluated the effect of adding orange, pineapple, and beet juices in different concentrations and combinations to the ram semen cryopreservation extender. Five ejaculates from five adult rams were used. The semen pool was diluted in egg yolk-based extender and mixed with the following 15 treatments (at a final concentration of 400.106 sptz/mL): orange 10% (O10) and 15% (O15); pineapple 10% (P10) and 15% (P15); beet 10% (B10) and 15% (B15); pineapple + orange 10% (PO10) and 15% (PO15); pineapple + beet 10% (PB10) and 15% (PB15); beet + orange 10% (BO10) and 15% (BO15); pineapple + beet + orange 10% (PBO10) and 15% (PBO15); and the control group (CON). Post-thaw in 0.25 mL straws semen quality analysis of cryopreserved semen was performed by CASA and flow cytometry. Analysis of variance (PROC GLM) was carried out and the averages were compared using the SNK test. Pearson's correlation test was also performed. No effect was noted in the addition of juices to the semen extender prior to cryopreservation. Post-thawed, although, statistically similar to the control group, the total motility of the B10 group reached acceptable standards of total motility. In addition, B10 group showed the highest values (p<0.05) of progressive motility than control group or other treatments. The addition of 10% beet juice to the ram semen extender can improve the cryopreservation of sperm motility.

Abstract
Resumo Em busca de melhorias na criopreservação do sêmen, substâncias naturais são comumente estudadas com o objetivo de melhorar a qualidade do sêmen. O objetivo deste estudo foi avaliar o efeito da adição de sucos de laranja, abacaxi e beterraba em diferentes concentrações e combinações ao diluidor de criopreservação de sêmen ovino. Foram utilizados cinco ejaculados de cinco carneiros adultos. O pool de sêmen foi diluído em diluente à base de gema de ovo e misturado com os seguintes 15 tratamentos (na concentração final de 400x10⁶ sptz/ml): laranja 10% (O10) e 15% (O15); abacaxi 10% (P10) e 15% (P15); beterraba 10% (B10) e 15% (B15); abacaxi + laranja 10% (PO10) e 15% (PO15); abacaxi + beterraba 10% (PB10) e 15% (PB15); beterraba + laranja 10% (BO10) e 15% (BO15); abacaxi + beterraba + laranja 10% (PBO10) e 15% (PBO15); e o grupo controle (CON). Pós-descongelação em palhetas de 0,25 ml a análise da qualidade do sêmen criopreservado foi realizada pelo CASA e citometria de fluxo. A análise de variância foi realizada e as médias comparadas pelo teste SNK. O teste de correlação de Pearson também foi realizado. Nenhum efeito foi observado na adição de sucos ao diluidor de sêmen antes da criopreservação. Após o descongelamento, embora estatisticamente semelhante ao grupo controle, a motilidade total do grupo B10 atingiu padrões aceitáveis de motilidade total. Além disso, o grupo B10 apresentou os maiores valores (p<0,05) de motilidade progressiva que o grupo controle ou os outros tratamentos. A adição de 10% de suco de beterraba ao diluente de sêmen ovino pode melhorar a criopreservação da motilidade espermática.

Abstract
Flow cytometry becomes a common method for analysis of spermatozoa quality. Standard sperm characteristics such as viability, acrosome and chromatin integrity, oxidative damage (ROS) etc. can be easily assess in any animal semen samples. Moreover, several fertility-related markers were observed in humans and some other mammals. However, these fertility biomarkers have not been previously studied in ram. The aim of this study was to optimize the flow-cytometric analysis of these standard and novel markers in ram semen. Ram semen samples from Slovak native sheep breeds were analyzed using CASA system for motility and concentration and were subsequently stained with several fluorescent dyes or specific antibodies to evaluate sperm viability (SYBR-14), apoptosis (Annexin V, YO-PRO-1, FLICA, Caspases 3/7), acrosome status (PNA, LCA, GAPDHS), capacitation (merocyanine 540, FLUO-4 AM), mitochondrial activity (MitoTracker Green, rhodamine 123, JC-1), ROS (CM-H2DCFDA, DHE, MitoSOX Red, BODIPY), chromatin (acridine orange), leukocyte content, ubiquitination and aggresome formation, and overexpression of negative biomarkers (MKRN1, SPTRX-3, PAWP, H3K4me2). Analyzed semen samples were divided into two groups according to viability as indicators of semen quality: Group 1 (viability over 60%) and Group 2 (viability under 60%). Significant (p < 0.05) differences were found between these groups in sperm motility and concentration, apoptosis, acrosome integrity (only PNA), mitochondrial activity, ROS production (except for DHE), leukocyte and aggresome content, and high PAWP expression. In conclusion, several standard and novel fluorescent probes have been confirmed to be suitable for multiplex ram semen analysis by flow cytometry as well as several antibodies have been validated for the specific detection of ubiquitin, PAWP and H3K4me2 in ram spermatozoa.

The Impact of Bacteriocenoses on Sperm Vitality, Immunological and Oxidative Characteristics of Ram Ejaculates: Does the Breed Play a Role? Animals (Basel) 2021; 12:ani12010054.

Abstract
Bacterial contamination of semen is an often overlooked, yet important, factor contributing to decreased sperm vitality. Understanding the impact of bacterial presence on sperm structural integrity and functional activity may assist the development of effective strategies to prevent, or manage, bacteriospermia in the breeding practice. The aim of this study was to describe the bacterial profiles of ram semen (n = 35), and we also focused on the associations between bacteriospermia, sperm structure, and function, as well as oxidative and inflammatory characteristics of semen. For a better insight, the samples were divided into three groups, according to the breeds used in the study: native Wallachian (NW), improved Wallachian (IW), and Slovak dairy (SD) breeds. The results showed a significantly lower motility and membrane integrity in the NW group in comparison to the IW and SD groups, which was accompanied by a significantly higher concentration of leukocytes, increased reactive oxygen species (ROS) generation, and subsequent oxidative insults to the sperm lipids and proteins. Accordingly, the NW group presented with the highest bacterial load, in which Staphylococcus and Escherichia were the predominant representatives. The Pearson correlation analysis uncovered positive relationships amongst the bacterial load and leukocytospermia (r = 0.613), the extent of lipid peroxidation (r = 0.598), protein oxidation (r = 0.514), and DNA fragmentation (r = 0.638). Furthermore, positive correlations were found between the bacterial load and pro-inflammatory molecules, such as the C-reactive protein (r = 0.592), interleukin 1 (r = 0.709), and interleukin 6 (r = 0.474), indicating a possible involvement of the immune response in the process of bacteriospermia. Overall, our data indicate that ram semen quality may be equally affected by the bacterial load and diversity. Furthermore, we can assume that the presence of bacteria in ejaculates triggers inflammatory processes, causes ROS overproduction, and, thereby, contributes to alterations in the sperm structure, while at the same time compromising the fertilization ability of male gametes.
