Abstract
Sperm motility is a natural selection with a crucial role in both natural and assisted reproduction. Common methods for increasing sperm motility are by using chemicals that cause embryotoxicity, and the multistep washing requirements of these methods lead to sperm DNA damage. We propose a rapid and noninvasive mechanotherapy approach for increasing the motility of human sperm cells by using ultrasound operating at 800 mW and 40 MHz. Single-cell analysis of sperm cells, facilitated by droplet microfluidics, shows that exposure to ultrasound leads to up to 266% boost to motility parameters of relatively immotile sperm, and as a result, 72% of these immotile sperm are graded as progressive after exposure, with a swimming velocity greater than 5 micrometer per second. These promising results offer a rapid and noninvasive clinical method for improving the motility of sperm cells in the most challenging assisted reproduction cases to replace intracytoplasmic sperm injection (ICSI) with less invasive treatments and to improve assisted reproduction outcomes.

Abstract
Appropriate stallion semen handling is of great importance in equine artificial insemination (AI) industry. Optimal treatment of AI doses is aiming for best sperm preservation by excluding strong environmental influences and adding media that favour sperm survival. One method widely used in stallion sperm handling is the rotation of liquid-preserved semen samples on roller benches during storage. As previous studies in boars give rise to the fact that rotation should not be considered beneficial for spermatozoa anymore, the present study investigated the influence of continuous rotation of diluted stallion AI portions on sperm quality. Ejaculates (n = 15) were collected at a German AI centre and diluted with the two extenders EquiPlus and Gent (Minitüb GmbH) to a final concentration of 50 × 106 sperm/mL. Afterwards, samples were placed separately on roller benches at 5°C in the dark, obtaining a rotation frequency of 5 revolutions per minute (rpm) and 36 rpm for four consecutive days following a split-sample design. Both groups were analysed daily in comparison to a control group (0 rpm) with an extended spectrum of spermatological methods including computer-assisted sperm analysis and flow cytometry. Statistical analyses were based on the calculation of generalized linear mixed models for each sperm parameter. The research revealed a decrease in sperm quality parameters of rotated samples compared to non-rotated control groups, visible in total sperm motility (p < .001), decreased thermo-resistance (p < .01) and a drop in pH (p < .001). Interestingly, no differences (p > .05) were detected between rotation frequencies of 5 and 36 rpm. We conclude that the fertilizing capacity of stallion semen was negatively affected by rotation during storage in vitro, irrespective of the rotation frequency. Further studies need to investigate whether field fertility in horses is similarly affected by semen rotation on roller benches in vivo.

Abstract
Cryopreservation of stallion semen does not achieve the post-thaw quality or fertility results observed in other species like cattle. There are many reasons for this, but the membrane composition and intracellular changes in stallion sperm predispose them to low resistance to the cooling, freezing, and subsequent thawing process. Damage to the sperm results from different processes activated during cryopreservation, including oxidative stress, apoptosis, and structural modifications in the sperm membrane that increase the deleterious effect on sperm. In addition, significant individual variability is observed among stallions in the ability of sperm to survive the freeze-thaw process. Recent advances in genomics, transcriptomics, proteomics, metabolomics, and epigenetics are making it possible to advance our understanding of the cellular and molecular processes involved in the cryopreservation process, opening new possibilities for improvement. This review addresses the ongoing research on stallion semen cryopreservation, focusing on the cellular and molecular consequences of this procedure in stallions and discusses the new tools currently available to increase the tolerance of equine spermatozoa to freeze-thaw.

Abstract
Sperm cells rely on different substrates to fulfil thei energy demand for different functions and diverse moments of their life. Species specific mechanism involve both energy substrate transport and their utilization: hexose transporters, a protein family of facilitative passive transporters of glucose and other hexose, have been identified in spermatozoa of different species and, within the species, their localization has been identified and, in some cases, linked to specific glycilitic enzyme presence. The catabolism of hexose sources for energy purposes has been studied in various species, and recent advances has been made in the knowledge of metabolic strategies of sperm cells. In particular, the importance of aerobic metabolism has been defined and described in horse, boar and even mouse spermatozoa; bull sperm cells demonstrate to have a good adaptability and capacity to switch between glycolysis and oxidative phosphorylation; finally, dog sperm cells have been demonstrated to have a great plasticity in energy metabolism management, being also able to activate the anabolic pathway of glycogen syntesis. In conclusion, the study of energy management and mitochondrial function in spermatozoa of different specie furnishes important base knowledge to define new media for preservation as well as newbases for reproductive biotechnologies.

Abstract
The semen quality of breeder cocks profoundly impacted the numbers of matched layer hens and the economic benefits of the poultry industry. Adequacy and balance of poultry nutrition, especially the energy provision, critically modulated the reproductive potential of breeder cocks, however, the underlying mechanism was still unclear. For the purpose of this study, a total of 90 yellow-feathered 13-week-old roosters with the same age in days and similar body weight (1,437 ± 44.3 g) were selected and randomly divided into the low energy diet (LE), the moderate energy diet (ME), and the high energy diet (HE) treatments. The phenotypic parameters related to reproduction include semen quality, fertility, and hatchability, and the testis morphological parameters, including seminiferous epithelium length (SEL), seminiferous tubule perimeter (STP), seminiferous tubule area (STA), and Johnsen score, were measured to investigate the regulatory effects of different energy diets on reproductive performances. Furthermore, spermatogenesis and sperm motility-related genes, which included the sry-related high mobility group box (SOX) gene family and sperm-associated antigen (SPAG) gene family, and mitochondria apoptosis-related genes, such as Cyt-C, Bcl-2, and Bax, were measured to determine the underlying mechanism of energy on the reproductive performances. The The results showed that the gonadosomatic index and sperm motility in the ME treatment significantly increased compared with the LE treatment. Chickens in the ME treatment showed a preferable performance of testis development, especially a significant increment of SEL and Johnsen Score, compared with the LE and HE treatments. Finally, spermatogenesis-related genes, which included SPAG6, SPAG16, SOX5, SOX6, and SOX13, and apoptosis-related genes of mitochondria, such as the Cyt-C and Bcl-2, were significantly upregulated in the ME treatment. This study concluded that proper energy provision stimulated regular energy metabolism for spermatogenesis and sperm capacitation, which finally increased semen quality and reproductive performances of breeder cocks.

Abstract
This study aimed at evaluating the relationship between biomarkers of oxidative stress (OS) in seminal plasma and sperm motility in bulls before and after cryopreservation. Three ejaculates per bull were collected from 20 young bulls. Each ejaculate was analyzed for motility before and after cryopreservation (by CASA), and the SP concentration of Advanced Oxidation Protein Products (AOPP), thiols, and carbonyl groups (CT) were examined. Then, based on their motility, the ejaculates were grouped into: high motility fresh (HMF), low motility fresh (LMF), high motility thawed (HMT), and low motility thawed (LMT) groups. Higher AOPP and thiol concentrations on SP were related (p < 0.05) to the higher LIN and BCF and lower ALH of fresh semen. In addition, AOPP and thiols were significantly higher in HMF than LMF. As a confirmation of this, the Receiver Operating Characteristic (ROC) curve analysis showed that AOPP and thiol concentrations in SP were able to discriminate between HMF and LMF ejaculates (Area Under the Curve of 71.67% and 72.04%, respectively). These observations give an alternative perspective on the relationship between sperm motility and the OS parameters of SP, which need further investigations.

Abstract
BACKGROUND Motility, morphology, membrane integrity and DNA fragmentation are sperm characteristics routinely used to assess quality of boar spermatozoa. However, the evaluation of individual parameters has intrinsic restrictions in the estimation of potential fertility. Therefore, we aimed to validate a new multiparametric protocol to assess fertility potential through the evaluation of viability, acrosome integrity and mitochondrial activity within the same sperm population for cooled and frozen-thawed boar spermatozoa. METHOD Three multicolor protocols to assess viability, acrosome integrity and/or mitochondrial activity were compared for agreement containing two dyes (HM-panel; Hoechst 33342, MitoTracker™ Deep Red), three dyes (3-panel; SYBR®14, propidium iodide and lectin PNA-Alexa™ 647) or four dyes (4-panel; Hoechst 33342, lectin PNA-Alexa™ 488, propidium iodide and MitoTracker™ Deep Red). Cooled (n = 132) and frozen-thawed (n = 254) samples of boar spermatozoa were assessed by flow cytometry. RESULTS 4-Panel enabled the detection of several sperm subpopulations based on plasma membrane integrity, acrosome status and mitochondrial activity in cooled and frozen-thawed spermatozoa. No significant differences were observed between 3-panel and 4-panel for the percentage of live, live-acrosome intact, and dead-acrosome reacted spermatozoa. However, the percentage of acrosome-intact spermatozoa was significantly higher in cooled samples when stained by 3-panel than 4-panel. Percentages of sperm parameters between protocols were strongly correlated, and agreement analysis demonstrated that both assays resulted in similar values for both sperm sample type. CONCLUSION Our results indicate that a four-color protocol is a practical, simple and reliable procedure to simultaneously evaluate boar sperm viability, acrosome integrity and mitochondrial activity under clinical conditions.

Abstract
Research on the role of reactive oxygen species (ROS) in the aging process has advanced significantly over the last two decades. In light of recent findings, ROS takes part in the aging process of cells along with contributing to various physiological signaling pathways. Antioxidants being cells' natural defense mechanism against ROS-mediated alteration, play an imperative role to maintain intracellular ROS homeostasis. Although the complete understanding of the ROS regulated aging process is yet to be fully comprehended, current insights into various sources of cellular ROS and their correlation with the aging process and age-related diseases are portrayed in this review. In addition, results on the effect of antioxidants on ROS homeostasis and the aging process as well as their advances in clinical trials are also discussed in detail. The future perspective in ROS-antioxidant dynamics on antiaging research is also marshaled to provide future directions for ROS-mediated antiaging research fields.

Abstract
Sperm mitochondrion is one of the major susceptible organelles that get damaged during cryopreservation. The study aimed to minimize mitochondrial dysfunction and oxidative stress during sperm cryopreservation using mitochondria-specific antioxidants. For this, semen was collected from five buffalo bulls (3 ejaculates/bull). The ejaculates were diluted in an low-density lipoprotein-based extender and divided into four equal aliquots. Mitochondria-targeted antioxidant (MitoQ) was added at a final concentration of 0 (control), 0.02, 0.2 and 2 μM separately in each aliquotes and cryopreserved. The addition of MitoQ at a concentration of 0.02 μM improved post-thaw sperm motility, plasma membrane integrity and able to sustain sperm motility for a longer time. To investigate MitoQ's effects on mitochondrial function, we measured mitochondrial membrane potential (MMP) using JC-1 dye, superoxide production using Mitosox assay, and lipid peroxidation by TBARS assay. The supplementation of 0.02 μM MitoQ in the extender prevented the significant reduction of MMP and reduced superoxide production resulting in lower lipid peroxidation of sperm plasma membrane after cryopreservation. Further, we found that a higher concentration of MitoQ decreases MMP and increases mitochondrial superoxide production. In conclusion, MitoQ @ 0.02 μM can alleviate oxidative stress by regulating mitochondrial functionality in spermatozoa during cryopreservation.

Abstract
The aim of this study was to determine an ozone dosage capable of inducing pro-oxidation, and to verify its action on sperm cells during the process of cooling and cryopreservation of equine semen. In this study, we evaluated the ozone concentrations of 2µg/mL,15µg/mL, 30µg/mL e 60 µg/mL added in equine semen cooling and freezing extenders. Samples were evaluated for sperm kinetics patterns, function of sperm structures and lipid peroxidation. In the experiment, the concentration of 15 µg/mL showed higher total and progressive motility when comparing to control (60.3±3 and 40.7±3.4 vs. 54.9±4 e 35.0±4.4, respectively, P < .05) at M24 of cooling; The concentration of 2 µg/mL showed higher percentage of intact plasma and acrosomal membrane when comparing to control at M24 (51.1±3.6 vs. 46.1±3.9, P < .05), M24 after 30 minutes of incubation (43.4±3.1 versus 32.4±2.6, P <.05). The concentration of 2 µg/mL showed higher percentage of intact plasma and acrosomal membrane (P <.05) comparing to control at moments M0 (43.5±5.0 vs. 36.3±3.5), M30 (41.0±3,7 vs. 35.3±2,9) e M60 (39.0±7.0 vs. 31.4±5.4). Thus, it can be concluded that low doses of ozone can lead to a positive response in the sperm kinetics patterns and sperm structures after sperm storage at low temperatures. Higher concentrations (30 and 60 µg/mL) were harmful in the cooling and cryopreservation of equine semen.

Abstract
Simple Summary Male fertility is often estimated by simple sperm assessment, and therefore, it is crucial to establish species-specific baselines for normal sperm parameters. In this paper, sperm physiology, function, and common abnormalities in stallions will be reviewed. Abstract As the use of assisted reproductive technologies (ART) and in vitro embryo production (IVP) expand in the equine industry, it has become necessary to further our understanding of semen physiology as it applies to overall fertility. This segment of our two-section review will focus on normal sperm parameters, beginning with development and extending through the basic morphology of mature spermatozoa, as well as common issues with male factor infertility in IVP. Ultimately, the relevance of sperm parameters to overall male factor fertility in equine IVP will be assessed.

Abstract
Spatial organization of mitochondria is vital for cellular function. In many specialized cell types, mitochondria are immobilized at specific subcellular loci through interactions with the cytoskeleton. One of the most striking mitochondrial configurations occurs in mammalian sperm, where mitochondria wrap around the flagellum. Malformation of the mitochondrial sheath causes infertility, but the molecular structures underlying this intricate arrangement are unknown. Here, we analyzed the mitochondrial sheath in sperm from three mammalian species. We find that although mitochondrial dimensions and cristae architecture vary across species, molecular assemblies mediating intermitochondria and mitochondria–cytoskeleton interactions are conserved. These findings yield important insight into sperm physiology and evolution and are relevant for other polarized cell types, such as muscles, neurons, photoreceptors, and hair cells. Mitochondria–cytoskeleton interactions modulate cellular physiology by regulating mitochondrial transport, positioning, and immobilization. However, there is very little structural information defining mitochondria–cytoskeleton interfaces in any cell type. Here, we use cryofocused ion beam milling-enabled cryoelectron tomography to image mammalian sperm, where mitochondria wrap around the flagellar cytoskeleton. We find that mitochondria are tethered to their neighbors through intermitochondrial linkers and are anchored to the cytoskeleton through ordered arrays on the outer mitochondrial membrane. We use subtomogram averaging to resolve in-cell structures of these arrays from three mammalian species, revealing they are conserved across species despite variations in mitochondrial dimensions and cristae organization. We find that the arrays consist of boat-shaped particles anchored on a network of membrane pores whose arrangement and dimensions are consistent with voltage-dependent anion channels. Proteomics and in-cell cross-linking mass spectrometry suggest that the conserved arrays are composed of glycerol kinase-like proteins. Ordered supramolecular assemblies may serve to stabilize similar contact sites in other cell types in which mitochondria need to be immobilized in specific subcellular environments, such as in muscles and neurons.

Increased mitochondrial activity upon CatSper channel activation is required for mouse sperm capacitation. Redox Biol 2021; 48:102176. [PMID: 34753004 PMCID: PMC8585656 DOI: 10.1016/j.redox.2021.102176] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 10/29/2021] [Accepted: 10/29/2021] [Indexed: 11/29/2022] Open
Abstract
To fertilize an oocyte, sperm must undergo several biochemical and functional changes known as capacitation. A key event in capacitation is calcium influx through the cation channel of sperm (CatSper). However, the molecular mechanisms of capacitation downstream of this calcium influx are not completely understood. Capacitation is also associated with an increase in mitochondrial oxygen consumption, and several lines of evidence indicate that regulated calcium entry into mitochondria increases the efficiency of oxidative respiration. Thus, we hypothesized that calcium influx through CatSper during capacitation increases mitochondrial calcium concentration and mitochondrial efficiency and thereby contributes to sperm hyperactivation and fertilization capacity. To test this hypothesis, we used high-resolution respirometry to measure mouse sperm mitochondrial activity. We also measured mitochondrial membrane potential, ATP/ADP exchange during capacitation, and mitochondrial calcium concentration in sperm from wild-type and CatSper knockout mice. We show that the increase in mitochondrial activity in capacitated wild-type sperm parallels the increase in mitochondrial calcium concentration. This effect is blunted in sperm from CatSper knockout mice. Importantly, these mechanisms are needed for optimal hyperactivation and fertilization in wild-type mice, as confirmed by using mitochondrial inhibitors. Thus, we describe a novel mechanism of sperm capacitation. This work contributes to our understanding of the role of mitochondria in sperm physiology and opens the possibility of new molecular targets for fertility treatments and male contraception.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 271:113810. [PMID: 33508368 DOI: 10.1016/j.jep.2021.113810] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 12/12/2020] [Accepted: 01/08/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sperm infertility and testicular atrophy are symptoms associated with aging. BaZiBuShen formula (BZBS), a patented Chinese herbal prescription composed of Semen Cuscutae, Fructus Lycii, Epimedii Folium, Fructus Schisandrae Sphenantherae, Fructus Cnidii, Fructus Rosae Laevigatae, Semen Allii Tuberosi., Radix Morindae Officinalis, Herba Cistanches, Fructus Rubi, Radix Rehmanniae Recens, Radix Cyathulae, Radix Ginseng, Cervi Cornu Pantotrichum, Hippocampus, and Fuctus Toosendan, has been used as a kidney-tonifying and anti-aging drug as well as for the treatment of impotence and male infertility in traditional Chinese medicine. AIM OF THE STUDY We aimed at investigating whether BZBS preserves sperm and testes morphology in aging mice, and to explore the underlying mechanisms. MATERIALS AND METHODS BZBS was orally administered to aging mice induced by D-galactose (D-gal) and NaNO2 for 65 days. Sperm quality and testes pathophysiological alterations were examined by a Semen Analysis System, hematoxylin-eosin staining, transmission electron microscopy, and mitochondrial complex IV activity. In addition, serum levels of total antioxidant capacity (TAC), malondialdehyde (MDA), 8-hydroxy-desoxyguanosine (8-OH-dG), reduced glutathione (GSH), oxidized glutathione disulfide (GSSG), testosterone (T), follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) and tumor necrosis factor-α (TNF-α) were determined by ELISA. The expressions of P450 aromatase (CYP19), sirtuin 6 (Sirt6), P53, inducible nitric oxide synthase (iNOS), nuclear factor-kappa B (NF-κB)-p65, and phospho-NF-κB-p65 (NF-κB-pp65) in the testes were examined by western blot and/or immunohistochemical staining. RESULTS Sustained exposure to D-gal/NaNO2 caused a deterioration of sperm quality and testes morphology in this rapid aging mouse model. BZBS treatment curtailed these alterations. These beneficial effects were associated with increased serum levels of TAC, GSH/GSSG, T, E2, and FSH, and decreased levels of MDA, TNF-α, and 8-OH-dG. BZBS treatment also downregulated the expressions of P53, iNOS, and NF-κB-pp65, as well as upregulated the expressions of Sirt6 and CYP19 in aging testes. CONCLUSIONS BZBS preserves testicular morphology and spermatogenesis possibly via inhibition of oxidative stress and the modulation of the Sirt6/P53 and Sirt6/NF-κB signaling pathways. The results shed light on the beneficial effect of BZBS on sperm quality and fertility in aging males.

Comparative Analysis of piRNA Profiles Helps to Elucidate Cryoinjury Between Giant Panda and Boar Sperm During Cryopreservation. Front Vet Sci 2021; 8:635013.

Abstract
Cryopreservation induces sperm cryoinjuries, including physiological and functional changes. However, the molecular mechanisms of sperm cryoinjury and cryoresistance are still unknown. Cryoresistance or the freeze tolerance of sperm varies across species, and boar sperm is more susceptible to cold stress. Contrary to boar sperm, giant panda sperm appears to be strongly freeze-tolerant and is capable of surviving repeated cycles of freeze-thawing. In this study, differentially expressed (DE) PIWI-interacting RNAs (piRNAs) of fresh and frozen-thawed sperm with different freeze tolerance capacity from giant panda and boar were evaluated. The results showed that 1,160 (22 downregulated and 1,138 upregulated) and 384 (110 upregulated and 274 downregulated) DE piRNAs were identified in giant panda and boar sperm, respectively. Gene ontology (GO) enrichment analysis revealed that the target DE messenger RNAs (mRNAs) of DE piRNAs were mainly enriched in biological regulation, cellular, and metabolic processes in giant panda and boar sperm. Moreover, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated that the target DE mRNAs of DE piRNAs were only distributed in DNA replication and the cyclic adenosine monophosphate (cAMP) signaling pathway in giant panda, but the cAMP, cyclic guanosine monophosphate (cGMP), and mitogen-activated protein kinase (MAPK) signaling pathways in boar sperm were considered as part of the olfactory transduction pathway. In conclusion, we speculated that the difference in the piRNA profiles and the DE piRNAs involved in the cAMP signaling pathway in boar and giant panda may have contributed to the different freeze tolerance capacities between giant panda and boar sperm, which helps to elucidate the molecular mechanism behind sperm cryoinjury and cryoresistance.

Abstract
As the vital organelles for cell energy metabolism, mitochondria are essential for oocyte maturation, fertilization, and embryo development. Abnormalities in quantity, quality, and function of mitochondria are closely related to poor fertility and disorders, such as decreased ovarian reserve (DOR), premature ovarian aging (POA), and ovarian aging, as well as maternal mitochondrial genetic disease caused by mitochondrial DNA (mtDNA) mutations or deletions. Mitochondria have begun to become a therapeutic target for infertility caused by factors such as poor oocyte quality, oocyte aging, and maternal mitochondrial genetic diseases. Mitochondrial replacement therapy (MRT) has attempted to use heterologous or autologous mitochondria to rebuild healthy state of oocyte by increasing the amount of mitochondria (e.g., partial ooplasm transfer, autologous mitochondrial transfer), or to stop the transmission of mtDNA diseases by replacing abnormal maternal mitochondria (e.g., pronuclei transfer, spindle transfer, polar body transfer). Among them, autologous mitochondrial transfer is the most promising therapeutic technology as of today which does not involve using a third party, but its clinical efficacy is controversial due to many factors such as the aging phenomenon of germ line cells, the authenticity of the existence of ovarian stem cells (OSC), and secondary damage caused by invasive surgery to patients with poor ovarian function. Therefore, the research of optimal autologous cell type that can be applied in autologous mitochondrial transfer is an area worthy of further exploration. Besides, the quality of germ cells can also be probably improved by the use of compounds that enhance mitochondrial activity (e.g., coenzyme Q10, resveratrol, melatonin), or by innovative gene editing technologies which have shown capability in reducing the risk of mtDNA diseases (e.g., CRISPR/Cas9, TALENTs). Though the current evidences from animal and clinical trials are not sufficient, and some solutions of technical problems are still needed, we believe this review will guide a new direction in the possible clinical applied mitochondrial-related therapeutic strategies in reproductive medicine.

Abstract
BACKGROUND The isolation and characterization of sperm subpopulations that can achieve fertilization is a major challenge of assisted reproduction methods. We focused on the microfluidic sperm sorter as a novel tool for collecting highly motile spermatozoa from heterogeneous semen samples. OBJECTIVES This study primarily aims to obtain baseline information on sorted spermatozoa according to its characteristics and in vitro life span. MATERIALS AND METHODS Frozen-thawed bull semen was subjected to microfluidic sperm sorting using diffuser-type microfluidic sperm sorter (DMSS). After sorting, samples were collected as the sorted spermatozoa and unsorted residual spermatozoa and incubated at 37°C for subsequent evaluation. The samples were assessed at different time points (0 or 1, 6, and 24 h) in terms of motility, which was measured by computer-assisted sperm analysis (CASA), membrane integrity, mitochondrial function, and adenosine triphosphate (ATP) production after sorting (0 h). To determine the characteristics and efficiency of DMSS sorting, the sorted spermatozoa were compared with samples collected using the swim-up method, a conventional method in motile sperm selection. RESULTS A comparison between the sorted and residual spermatozoa demonstrated significantly higher motility parameters, membrane integrity, and mitochondrial function of the sorted spermatozoa until 6 h after incubation. The time course decrement of membrane and mitochondrial status were subjected to curve fitting and theoretically supported. Sperm ATP production measured immediately after sorting showed higher ATP generation of the sorted spermatozoa compared with the unsorted, frozen-thawed spermatozoa. The motility parameters and mitochondrial activity of DMSS-sorted spermatozoa were higher than the swim-up-collected spermatozoa (p < 0.05). DISCUSSION AND CONCLUSION These results indicate that DMSS sorting can strictly select highly motile spermatozoa with the ability to maintain its membrane integrity and mitochondrial function related to ATP production. We speculate that the device that is able to sort high-quality spermatozoa can have great potential in assisted reproduction.

Abstract
This work aimed to investigate how stimulation of donkey sperm with red LED light affects mitochondrial function. For this purpose, freshly diluted donkey semen was stimulated with red light for 1, 5, and 10 min, in the presence or absence of oligomycin A (Omy A), a specific inhibitor of mitochondrial ATP synthase, or FCCP, a specific disruptor of mitochondrial electron chain. The results obtained in the present study indicated that the effects of red LED light on fresh donkey sperm function are related to changes in mitochondria function. In effect, irradiation of donkey sperm resulted in an increase in mitochondrial membrane potential (MMP), the activity of cytochrome C oxidase and the rate of oxygen consumption. In addition, in the absence of oligomycin A and FCCP, light-stimulation augmented the average path velocity (VAP) and modified the structure of motile sperm subpopulations, increasing the fastest and most linear subpopulation. In contrast, the presence of either Omy A or FCCP abolished the aforementioned effects. Interestingly, our results also showed that the effects of red light depend on the exposure time applied, as indicated by the observed differences between irradiation protocols. In conclusion, our results suggest that exposing fresh donkey sperm to red light modulates the function of their mitochondria through affecting the activity of the electron chain. However, the extent of this effect depends on the irradiation pattern and does not exclude the existence of other mechanisms, such as those related to thermotaxis.

Abstract
Under in vitro conditions, stallion sperm might preferentially use energy substrates that primarily undergo mitochondrial metabolism. The present study sought to determine the effects of glucose, pyruvate, lactate, or their combinations on the quality of stallion sperm subjected to cooled storage at different temperatures, when using a skim milk-based semen extender. In Experiment 1, no substrate (Control), glucose (40 mM; Glu-40), pyruvate (2 mM, 19.8 mM; Pyr-2, Pyr-19), lactate (2 mM, 19.8 mM; Lac-2, Lac-19, respectively), or their combinations (G/P/L-2 or G/P/L-19, respectively) were added to a milk-based extender and their effects were determined on motion characteristics, viability/acrosomal intactness (VAI), lipid peroxidation status (VLPP), and DNA integrity (COMPα-t) of sperm incubated for 1 h at 37 °C, or sperm stored for 24 h at either 10 or 20 °C. At any period and temperature tested, Glu-40, G/P/L-2, and G/P-L-19 resulted in similar motion characteristics (P > 0.05) but were higher than that of other treatment groups (P < 0.05). Mean VAI was highest in Glu-40 (P < 0.05). Mean VLPP was highest in G/P/L-2 and G/P/L-19 groups (P < 0.05), and mean COMPα-t was lowest in Control, Glu-40, G/P/L-2 and G/P/L-19 groups (P < 0.05). All measures of sperm quality were higher in semen stored at 10 °C than 20 °C (P < 0.05). In Experiment 2, increasing concentrations of either pyruvate or lactate (Pyr-40, Lac-40 or Pyr-80, Lac-80) were added to the extender as energy substrates and compared to glucose (40 mM), following storage for 72 h at either 10 or 20 °C. Groups Glu-40 and Pyr-40 yielded similar sperm motion characteristics and VAI, while VLPP and COMPα-t were reduced in these treatment groups, as compared to Pyr-80, Lac-40, and Lac-80 (P < 0.05). All measures of sperm quality were higher in semen stored at 10 °C vs 20 °C (P < 0.05). This study demonstrates that at storage temperatures of 10 or 20 °C, stallion sperm quality is optimized by the presence of glucose in a skim milk-based semen extender. The addition of substrates that readily support oxidative phosphorylation (i.e., pyruvate or lactate) did not improve the quality of stallion sperm over that of glucose alone and resulted in deleterious effects on sperm quality over time. These effects appeared to be associated with oxidative stress. Use of pyruvate (40 mM) as an alternative energy substrate to glucose generally yielded similar results to that of glucose when sperm were stored at 10 °C only.

Novel Low-Voltage Electro-Ejaculation Approach for Sperm Collection from Zoo Captive Lanyu Miniature Pigs ( Sus barbatus sumatranus). Animals (Basel) 2020; 10:ani10101825. [PMID: 33036420 PMCID: PMC7600073 DOI: 10.3390/ani10101825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 09/30/2020] [Accepted: 10/03/2020] [Indexed: 11/17/2022] Open
Abstract
Semen collection can be achieved via hand penile massage or rectal stimulation using electro-ejaculation methods. Traditional electro-ejaculation procedure applied relatively high voltage of 3-15 volts with a maximum current of 900 mA. However, these manipulations often result in great stress and discomforts in animals. In this study, we showed low-voltage electro-ejaculation procedure using 2-3 volts with a maximum current of 500 mA can efficiently stimulated ejaculations in zoo captive lanyu miniature pigs with a high success rate of 81.3% (13/16). Besides normal semen properties (semen volume, pH, sperm concentration), we demonstrated that low-voltage electro-ejaculation caused less stress in the animals, and sperm cells obtained via low-voltage electro-ejaculation exhibit low abnormality (10.3%), high viability (84.3%), motility (75.7%), progressive motility (63.7%), and acrosome integrity (88%). However, cryopreservation protocol used in the current study requires further optimization, as sperm mitochondrial function was partially compromised during freezing procedures. Taken together, we demonstrated in this study that a low-voltage electro-ejaculation approach can be used to obtain quality sperm cells from zoo captive lanyu miniature pig with less physical stress during electro-ejaculation procedure.

Red-Light Irradiation of Horse Spermatozoa Increases Mitochondrial Activity and Motility through Changes in the Motile Sperm Subpopulation Structure. BIOLOGY 2020; 9:biology9090254. [PMID: 32872467 PMCID: PMC7565061 DOI: 10.3390/biology9090254] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 08/27/2020] [Indexed: 01/15/2023]
Abstract
Previous studies in other mammalian species have shown that stimulation of semen with red-light increases sperm motility, mitochondrial activity, and fertilizing capacity. This study sought to determine whether red-light stimulation using a light emitting diode (LED) at 620–630 nm affects sperm motility and structure of motile subpopulations, sperm viability, mitochondrial activity, intracellular ATP levels, rate of O2 consumption and DNA integrity of horse spermatozoa. For this purpose, nine ejaculates were collected from nine different adult stallions. Upon collection, semen was diluted in Kenney extender, analyzed, its concentration was adjusted, and finally it was stimulated with red-light. In all cases, semen was packaged in 0.5-mL transparent straws, which were randomly divided into controls and 19 light-stimulation treatments; 6 consisted of a single exposure to red-light, and the other 13 involved irradiation with intervals of irradiation and darkness (light-dark-light). After irradiation, sperm motility was assessed using a Computerized Semen Analysis System (CASA). Flow cytometry was used to evaluate sperm viability, mitochondrial membrane potential and DNA fragmentation. Intracellular levels of ATP and O2 consumption rate were also determined. Specific red-light patterns were found to modify kinetics parameters (patterns: 4, 2-2-2, 3-3-3, 4-4-4, 5-1-5, and 5-5-5 min), the structure of motile sperm subpopulations (patterns: 2, 2-2-2, 3-3-3, and 4-1-4 min), mitochondrial membrane potential (patterns: 4, 3-3-3, 4-4-4, 5-1-5, 5-5-5, 15-5-15, and 15-15-15 min), intracellular ATP levels and the rate of O2 consumption (pattern: 4 min), without affecting sperm viability or DNA integrity. Since the increase in some kinematic parameters was concomitant with that of mitochondrial activity, intracellular ATP levels and O2 consumption rate, we suggest that the positive effect of light-irradiation on sperm motility is related to its impact upon mitochondrial activity. In conclusion, this study shows that red LED light stimulates motility and mitochondrial activity of horse sperm. Additional research is needed to address the impact of red-light irradiation on fertilizing ability and the mechanisms through which light exerts its effects.
