Exogenous Oxidative Stress in Human Spermatozoa Induces Opening of the Mitochondrial Permeability Transition Pore: Effect on Mitochondrial Function, Sperm Motility and Induction of Cell Death. Antioxidants (Basel) 2024; 13:739. [PMID: 38929178 PMCID: PMC11201210 DOI: 10.3390/antiox13060739] [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: 05/07/2024] [Revised: 05/28/2024] [Accepted: 05/29/2024] [Indexed: 06/28/2024] Open
Abstract
Oxidative stress (OS) and disrupted antioxidant defense mechanisms play a pivotal role in the etiology of male infertility. The alterations in reactive oxygen species (ROS) production and calcium (Ca2+) homeostasis are the main activators for the mitochondrial permeability transition pore (mPTP) opening. The mPTP opening is one of the main mechanisms involved in mitochondrial dysfunction in spermatozoa. This alteration in mitochondrial function adversely affects energy supply, sperm motility, and fertilizing capacity and contributes to the development of male infertility. In human spermatozoa, the mPTP opening has been associated with ionomycin-induced endogenous oxidative stress and peroxynitrite-induced nitrosative stress; however, the effect of exogenous oxidative stress on mPTP opening in sperm has not been evaluated. The aim of this study was to determine the effect of exogenous oxidative stress induced by hydrogen peroxide (H2O2) on mPTP opening, mitochondrial function, motility, and cell death markers in human spermatozoa. Human spermatozoa were incubated with 3 mmol/L of H2O2 for 60 min, and intracellular Ca2+ concentration, mPTP opening, mitochondrial membrane potential (ΔΨm), ATP levels, mitochondrial reactive oxygen species (mROS) production, phosphatidylserine (PS) externalization, DNA fragmentation, viability, and sperm motility were evaluated. H2O2-induced exogenous oxidative stress caused increased intracellular Ca2+, leading to subsequent mPTP opening and alteration of mitochondrial function, characterized by ΔΨm dissipation, decreased ATP levels, increased mROS production, and the subsequent alteration of sperm motility. Furthermore, H2O2-induced opening of mPTP was associated with the expression of apoptotic cell death markers including PS externalization and DNA fragmentation. These results highlight the role of exogenous oxidative stress in causing mitochondrial dysfunction, deterioration of sperm motility, and an increase in apoptotic cell death markers, including PS externalization and DNA fragmentation, through the mPTP opening. This study yielded new knowledge regarding the effects of this type of stress on mitochondrial function and specifically on mPTP opening, factors that can contribute to the development of male infertility, considering that the role of mPTP in mitochondrial dysfunction in human sperm is not completely elucidated. Therefore, these findings are relevant to understanding male infertility and may provide an in vitro model for further research aimed at improving human sperm quality.

Airborne environmentally persistent free radicals (EPFRs) in PM 2.5 from combustion sources: Abundance, cytotoxicity and potential exposure risks. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 927:172202.

Abstract
As an emerging atmospheric pollutant, airborne environmentally persistent free radicals (EPFRs) are formed during many combustion processes and pose various adverse health effects. In health-oriented air pollution control, it is vital to evaluate the health effects of atmospheric fine particulate matter (PM2.5) from different emission sources. In this study, various types of combustion-derived PM2.5 were collected on filters in a partial-flow dilution tunnel sampling system from three typical emission sources: coal combustion, biomass burning, and automobile exhaust. Substantial concentrations of EPFRs were determined in PM2.5 samples and associated with significant potential exposure risks. Results from in vitro cytotoxicity and oxidative potential assays suggest that EPFRs may cause substantial generation of reactive oxygen species (ROS) upon inhalation exposure to PM2.5 from anthropogenic combustion sources, especially from automobile exhaust. This study provides important evidence for the source- and concentration-dependent health effects of EPFRs in PM2.5 and motivates further assessments to advance public health-oriented PM2.5 emission control.

Abstract
The study aimed to explore the role and mechanism of unfolded protein response (UPR) in methylmercury (MeHg)-induced Mouse Spermatocytes (GC-2spd[ts]) apoptosis. Methods such as MTT, flow cytometry, and Western Blot were used to evaluate the cell viability, membrane potential (MMP), reactive oxygen species (ROS), calcium ion (Ca2+ ), rate of cell apoptosis, and the expression of apoptosis-related and UPR-related protein. The results showed that with the increase of MeHg concentration, cell viability and MMP decreased, ROS, Ca2+ , rate of cell apoptosis, and the expression of apoptosis-related protein and UPR-related protein increased. To further explore the effect of ROS-induced oxidative damage on it, the ROS inhibitor N-acetyl-L-cysteine (NAC) was used. The effects of MeHg on germ cell (GC-2) cells were partially inhibited after NAC pretreatment. Our present study proved that MeHg might induce cell apoptosis by activating the UPR signaling pathway in GC-2 cells and affect normal reproductive function.

Abstract
Significance: Currently 10%-15% of couples in reproductive age face infertility issues. More importantly, male factor contributes to 50% of these cases (either alone or in combination with female causes). Among various reasons, impaired sperm function is the main cause for male infertility. Furthermore, mitochondrial dysfunction and oxidative stress due to increased reactive oxygen species (ROS) production, particularly of mitochondrial origin, are believed to be the main contributors. Recent Advances: Mitochondrial dysfunction, particularly due to increased ROS production, has often been linked to impaired sperm function/quality. For decades, different methods and approaches have been developed to assess mitochondrial features that might correlate with sperm functionality. This connection is now completely accepted, with mitochondrial functionality assessment used more commonly as a readout of sperm functionality. More recently, mitochondria-targeted compounds are on the frontline for both assessment and therapeutic approaches. Critical Issues: In this review, we summarize the current methods for assessing key mitochondrial parameters known to reflect sperm quality as well as therapeutic strategies using mitochondria-targeted antioxidants aiming to improve sperm function in various situations, particularly after sperm cryopreservation. Future Directions: Although more systematic research is needed, mitochondria-targeted compounds definitely represent a promising tool to assess as well as to protect and improve sperm function.

Abstract
The present study was aimed to evaluate the effect of over dilution of semen with tris extender on motion and functional attributes of bull sperm post-thaw. Ejaculates (n = 24; mass motility ≥3+) were collected from bulls (n = 4) using artificial vagina, diluted to 20, 15, 10 and 5 million spermatozoa/0.25 ml, and cryopreserved. The results revealed that total motility (%), progressive motility (%) and rapid motility (%), straight linear velocity (μm/s), straightness (%) reduced significantly (p < 0.05) when semen was diluted to 5 million sperm concentration. Among the various sperm function attributes, proportions of live spermatozoa, acrosome intact spermatozoa, hypo-osmotic swelling responsive spermatozoa and non-capacitated spermatozoa reduced (p < 0.05) in 5 million spermatozoa, and the proportions of moribund spermatozoa, dead spermatozoa, live acrosome reacted spermatozoa, dead acrosome intact spermatozoa, capacitated spermatozoa and spermatozoa with lipid peroxidation increased significantly (p < 0.05) when semen was diluted from 20 to 5 million. However, the over-dilution of semen did not affect slow motility, dead acrosome reacted spermatozoa, sperm protamine deficiency and spermatozoa with lipid peroxidation. In conclusion, the over dilution of semen affected sperm motion and functional attributes of frozen-thawed bull semen.

Abstract
The reactive oxygen species (ROS) play an important role in various aspects of male reproductive function, for spermatozoa to acquire the ability to fertilize. However, the increase in ROS generation, both due to internal and external factors, can induce oxidative stress, causing alterations in the structure and function of phospholipids and proteins. In the nucleus, ROS attack DNA, causing its fragmentation and activation of apoptosis, thus altering gene and protein expression. Accumulating evidence also reveals that endogenously produced ROS can act as second messengers in regulating cell signalling pathways and in the transduction of signals that are responsible for regulating spermatogonia self-renewal and proliferation. In the epididymis, they actively participate in the formation of disulphide bridges required for the final condensation of chromatin, as well as in the phosphorylation and dephosphorylation of proteins contained in the fibrous sheath of the flagellum, stimulating the activation of progressive motility in epididymal spermatozoa. In this review, the role of small amounts of ROS during spermatogenesis and epididymal sperm maturation was discussed.

Abstract
This study investigated the effects of supplementing Lake extender with cysteamine (CYS) on rooster semen quality in cold storage and it's fertility performance. Semen samples were diluted with Lake extender supplemented with different concentrations of CYS (0, 1, 2, 4 and 8 mM) and were cooled and stored at 5 °C for a period of 46 h. Motility, membrane functionality, viability, lipid peroxidation, and mitochondria membrane potential were evaluated at 0, 23 and 46 h of storage. Fertility was assessed at 23 h of storage. Although at the beginning time (0 h), parameters were not affected, 1 mM of CYS improved (P ≤ 0.05) total motility, progressive motility and mitochondria membrane potential during 23 and 46 h storage. Moreover, 1 and 2 mM CYS improved (P ≤ 0.05) membrane functionality and viability compared to other groups. Lipid peroxidation was lower (P ≤ 0.05) in samples diluted with 1 and 2 mM CYS compared to the others. Artificial insemination with 23-hrs cooled-stored semen produced the higher (P ≤ 0.05) fertility rate in groups received 1 and 2 mM CYS compared to the control group. In conclusion, addition of 1 and 2 mM CYS to the extender could be helpful to protect rooster semen against structural and functional damages of cooling storage process.

Abstract
BACKGROUND Oxidative stress and reactive oxygen species (ROS) are primarily responsible for the development of male infertility after exposure to γ-irradiation. The present work aimed to assess the ameliorative and therapeutic roles of the aqueous and ethanolic extracts of the edible seaweed Sargassum virgatum (S. virgatum) on spermatogenesis and infertility in γ-irradiated Wistar rats. MATERIALS AND METHODS Induction of infertility was performed by exposing the rats to 137Cs-gamma rays, using a single dose of 3.5 Gy. γ-irradiated rats were given the S. virgatum ethanolic (S. virgatum-EtOH) and aqueous extracts intraperitoneally on a daily base for two consecutive weeks at doses of 100 and 400 mg/kg body weight (b.wt.) for each seaweed extract. Morphometric data of the testes, semen quality indices, antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and glutathione peroxidase (GPx), and deoxyribonucleic acid (DNA) fragmentation were assessed. The results obtained were taken during two-time intervals of 15 and 60 days from the commencement of the algal treatments. In vitro antioxidant assays and polyphenolic compounds of S. virgatum were characterized. RESULTS Significant negative changes in the semen quality and morphometric data of the testes, as well as remarkable DNA fragmentation, were detected in the irradiated rats compared to the control. The levels of the endogenous antioxidant enzymes (SOD, CAT, GSH, and GPx) were also significantly diminished. Nonetheless, treatments of γ-irradiated rats with the S. virgatum-EtOH and aqueous extracts significantly improved the above-mentioned enzymes, in addition to noteworthy amendments in the dimensions of the testes, the semen quality, as well as the DNA structure. CONCLUSIONS The ameliorative potency of S. virgatum to cure γ-irradiation-induced male infertility, particularly 400 mg/kg ethanolic extract for 60 days, is the result of the consistent therapeutic interventions of its potent antioxidant and anti-apoptotic polyphenols, particularly protocatechuic, p-hydroxybenzoic, rosmarinic, chlorogenic, cinnamic and gentisic acids, as well as the flavonoids catechin, hesperidin, rutin and quercetin. Besides its high-value nutraceutical importance, S. virgatum could be a natural candidate for developing well-accepted radioprotectant products capable of treating γ-irradiation-induced male infertility.

Abstract
This study aimed at evaluating the therapeutic effects of ethanolic extract of Polygonum limbatum meism (EEPLM) on the reproductive parameters of male Guinea pigs exposed to cadmium chloride. Thirty-six male guinea pigs were randomly assigned to six treatment groups (with six animals per group). Group 1 (DW) received distilled water orally; group 2 (Cd), negative control, was treated with cadmium chloride at a dose of 26.25 mg/kg body weight (bw); while group 3 (VitC), positive control, was given 26.25 mg of cadmium chloride/kg bw and 100 mg of vitamin C, and groups 4, 5, and 6 were treated, respectively, with EEPLM at doses of 50, 100, and 200 mg/kg bw in addition to cadmium chloride (26.25 mg/kg bw). After 90 days, all animals were sacrificed, and data related to reproduction, toxicity, and oxidative stress were collected. Results revealed a significant decrease (p < 0.05) of serum levels of creatinine, urea, alanine, and aspartate amino transferases in guinea pigs treated with cadmium chloride and EEPLM compared to the negative control group (Cd). The weight of the bulbo-urethral gland was significantly (p < 0.05) decreased in animals exposed to cadmium chloride and treated with vitamin C or EEPLM compared to the negative control (Cd). Guinea pigs orally receiving cadmium chloride and EEPLM showed significantly (p < 0.05) increased motility, sperm count, spermatozoa with entire plasma membrane, and percentage of normal spermatozoa with reference to the negative control (Cd). The serum level of testosterone increased insignificantly (p > 0.05) in animals given cadmium and EEPLM compared to the negative control (Cd). Animals co-administered cadmium chloride and EEPLM recorded a significantly (p < 0.05) reduced level of MDA, activities of SOD, and total peroxidases compared to the group that received cadmium chloride (Cd) only. In conclusion, cadmium chloride induced reproductive impairments by generating oxidative stress. However, the administration of EEPLM can mitigate these adverse effects due to its antioxidant properties.

Abstract
The primary task of a spermatozoon is to deliver its nuclear payload to the egg to form the next-generation zygote. With polyandry repeatedly evolving in the animal kingdom, however, sperm competition has become widespread, with the highest known intensities occurring in fish. Yet, the molecular controls regulating spermatozoon swimming performance in these organisms are largely unknown. Here, we show that the kinematic properties of postactivated piscine spermatozoa are regulated through a conserved trafficking mechanism whereby a peroxiporin ortholog of mammalian aquaporin-8 (Aqp8bb) is inserted into the inner mitochondrial membrane to facilitate H2O2 efflux in order to maintain ATP production. In teleosts from more ancestral lineages, such as the zebrafish (Danio rerio) and the Atlantic salmon (Salmo salar), in which spermatozoa are activated in freshwater, an intracellular Ca2+-signaling directly regulates this mechanism through monophosphorylation of the Aqp8bb N terminus. In contrast, in more recently evolved marine teleosts, such the gilthead seabream (Sparus aurata), in which spermatozoa activation occurs in seawater, a cross-talk between Ca2+- and oxidative stress-activated pathways generate a multiplier regulation of channel trafficking via dual N-terminal phosphorylation. These findings reveal that teleost spermatozoa evolved increasingly sophisticated detoxification pathways to maintain swimming performance under a high osmotic stress, and provide insight into molecular traits that are advantageous for postcopulatory sexual selection.

Abstract
Introduction: This research was conducted to assess the effect of myo-inositol (MYO) in the freezing extender on the semen quality and oxidative stress parameters of frozen-thawed bull sperm. Materials and Methods: Semen samples were obtained from four bulls (n = 24, six ejaculates per bull), twice a week, and diluted into four equal aliquots in freezing extenders containing different concentrations of MYO (0, 2, 3, and 4 mg/mL). After a freezing/thawing process, velocity parameters, plasma membrane integrity, apoptosis status, malondialdehyde level, and oxidative stress parameters were assessed. Results: Supplementation of freezing extender with 3 mg/mL MYO resulted in higher rapid motility (62.22% ± 2.63%), progressive motility (77.45% ± 2.65%), viability (78% ± 0.91%), plasma membrane integrity (86 ± 0.85), catalase (20.03 ± 0.39 U/mL) activity, and lower significance of lipid peroxidation (3.60 ± 0.15 nmol/dL) than those of the control group (p < 0.05). A significantly lower percentage of normal morphology and intact acrosomes were observed for frozen-thawed semen in the extender supplemented with 4 mg/mL MYO than those of the control group (p < 0.05). Freezing of the sperm in the extender containing 3 mg/mL of MYO leads to a higher percentage of live cells (38.3 ± 2.76). Beat-cross-frequency, amplitude of lateral head displacement, linearity, total antioxidant capacity, total peroxidase activity, early apoptotic status, and superoxide dismutase activities were not affected by MYO levels in the extenders (p > 0.05). Conclusion: The findings of this study suggest that the supplementation of the freezing extender with 3 mg/mL MYO resulted in a higher quality of frozen-thawed bull sperm.

Abstract
Since turkey reproduction is mainly through artificial insemination, short-term preservation of turkey semen is one of the most important issues in turkey reproduction management. The present study investigates the effects of glutathione (GSH) and trehalose on lipid peroxidation degree and turkey semen quality while being stored at 5 °C for 72 h. To this end, semen samples were collected from 20 turkeys with a weekly frequency for 12 weeks. A glucose-based extender was used to dilute the pooled semen. It was divided into seven equal parts with varying levels of glutathione [0.5, 1 and 2 mM), trehalose [50, 75 and 100] and control [extender without antioxidant]. Subsequently, the divided semen samples were stored at 5 °C for 72 h. Several sperm parameters such as motility and motion parameters, plasma membrane integrity (PMI), plasma membrane functionality, DNA integrity, and oxidative parameters were assessed following storage for 0, 24, 48, and 72 h. The obtained results indicated an improvement in the plasma membrane functionality and DNA integrity, along with the percentages of PMI in GSH-2 mM group in comparison to the control group following storage at 5 °C for 72 h (P ≤ 0.05). It is also notable that the 2 and 1 mM concentrations of GSH increased the spermatozoa motility and motion parameters in comparison to the control group, respectively (P ≤ 0.05). The study results indicated that GSH-2, 1 mM and trehalose- 100 mM concentrations reduced lipid peroxidase levels and increased total antioxidant activity, catalase, superoxide dismutase, and glutathione peroxidase in comparison to the control group (P ≤ 0.05). Our study's data show that improvement of semen parameters and oxidative stress parameters of turkey semen can be improved by glutathione at 2 and 1 mM and trehalose at 75 mM while storing it 5 °C.

Abstract
Variation in donkey sperm freezability (capacity to withstand freeze-thawing) between ejaculates is a limitation for sperm cryopreservation. Seminal plasma proteins are essential for sperm function and also related to individual differences in sperm freezability. A Tandem Mass Tag (TMT) peptide labeling combine with a LC-MS/MS approach was conducted to quantitatively identify the seminal plasma proteins differentially abundant in ejaculates with optimal freezability characteristics (GFE) compared with those with suboptimal freezability characteristics (PFE). A total of 866 proteins were identified, and 99 ejaculates were in larger abundance in GFE samples. Differentially abundant proteins (DAPs) were subjected to intensive bioinformatic analysis. The majority of DAPs were involved in metabolic processes, oxidation-reduction processes and biological regulation. Results from functional protein analysis suggested that proteins functioned in oxidoreductase activity and acid phosphatase activity. This is the first report where there were analyses of the proteome of seminal plasma from donkey ejaculates with different freezability and to identify candidate proteins that could be used to explore the molecular mechanism related to donkey sperm cryotolerance. In this study, there also was elucidation of biomarkers for the early identification and selection of donkeys with optimal semen freezability.

Abstract
BACKGROUND Excessive consumption of alcohol induces an increase in oxidative stress production and can lead to detrimental effects on the male reproductive system. OBJECTIVE To evaluate the possible protective effects of coadministration of vitamin (vit) E on the detrimental changes in the sperm quality of mice administered ethanol. MATERIALS AND METHODS Fifty-four BALB/c mice were categorized into nine groups (n = 6/each). The control group received a basal diet while the eight experimental groups received ethanol 10%; ethanol 20%; vit. E 100 mg; vit. E 200 mg; ethanol 10% + vit. E 100 mg; ethanol 10% + vit. E 200 mg; ethanol 20% + vit. E 100 mg; ethanol 20% + vit. E 200 mg. After 35 days, the sperm parameters and sperm chromatin were assessed. RESULTS The results demonstrated a significant reduction in the motility rate, normal morphology rate, viability rate, increase in abnormal DNA structure and packaging (TB staining), and DNA damage (TUNEL) in ethanol consumer groups. In addition, the findings showed a significant increase in the aforementioned parameters in ethanol- and vit. E-consumer groups compared to the ethanol-only consumer groups. The ethanol group received 20% of the most damage among the groups. The group receiving vit. E 100 mg and those receiving ethanol 10% + vit. E 200 mg gained the highest benefit among the groups. CONCLUSION Sperm forward progressive motility, normal morphology rate, and viability decreased in the ethanol groups. Also, the rates of spermatozoa with abnormal DNA structure and DNA fragmentation increased in the ethanol groups. Our findings revealed that the coadministration of vit. E and ethanol can protect destructive changes in DNA structure and damage.

Abstract
Quinalphos (QP) is one of the most commonly used organophosphate pesticide for agriculture. In this study, adult Swiss albino male mice were orally administered with 0.25, 0.5 and 1.0 mg/kg of QP (Ekalux 25 E.C.) for ten consecutive days and the reproductive function was assessed at 35 and 70 days after QP treatment. At highest dose (1.0 mg/kg), QP exposure resulted in significant decrease in motility and increase in sperm head defects and DNA damage. Pharmacokinetic data showed a threefold increase in concentration of QP in the testis as compared to serum. QP was detectable in testes even after 24 hr of administration indicating slow clearance from tissue. In addition, high oestradiol, low testosterone level with a parallel increase in aromatase and cytochrome P450 transcript levels was observed. Significant decrease in fertilisation, lower blastocyst rate and poor blastocyst quality was observed when spermatozoa collected from QP exposed mice were subjected to in vitro fertilisation. In conclusion, exposure of QP to male mice decreases the sperm functional competence and fertilising ability, which appears to be mediated through elevated oxidative stress and altered steroidogenesis in testes.

Abstract
The dogma of mitochondria as the major source of energy in supporting sperm motility should be critically reconsidered in the light of several experimental data pointing to a major role of glycolysis in mammalian spermatozoa. In this light, the reported positive correlation between the mitochondrial membrane potential (ΔΨm) and motility of ejaculated spermatozoa cannot be explained convincingly by an impaired mitochondrial ATP generation only. Evidence has been produced suggesting that, in human sperm, dysfunctional mitochondria represent the main site of generation of reactive oxygen species (ROS). Furthermore, in these organelles, a complex bidirectional relationship could exist between ROS generation and apoptosis-like events that synergize with oxidative stress in impairing sperm biological integrity and functions. Despite the activity of enzymatic and non-enzymatic antioxidant factors, human spermatozoa are particularly vulnerable to oxidative stress, which plays a major role in male factor infertility. The purpose of this article is to provide an overview of metabolic, oxidative and apoptosis-like inter-linkages of mitochondrial dysfunction and their reflections on human sperm biology.

Abstract
Lead toxicity is one of the causative agents of male infertility that raised concern from environmental contamination worldwide. L‐carnitine, a biologically active amino acid, present in high concentration in the reproductive organs such as the epididymis, is involved in sperm maturation. The possible protective effect of L‐carnitine in experimentally lead‐induced male reproductive toxicity in rats was evaluated in this study. Thirty adult male Wistar rats were divided into three groups. Group 1: the negative control group was treated with normal saline; Group 2: exposed to 50 mg/kg lead acetate (2% solution in saline); and Group 3: treated with lead acetate 50 mg/kg (2% solution in saline) + L‐carnitine 100 mg/kg. At the end of the experimental period, body and testicular weights were determined, blood samples were withdrawn for hormonal assays of FSH, LH and testosterone. Sperm parameters as sperm count, morphology, viability and motility were measured. Testicular tissue homogenates were prepared for enzymatic assays and for measuring oxidative stress parameters. Lead significantly increased both oxidative stress and the concentration of lactate dehydrogenase‐C in the testicular tissues with a decrease in sperm count, motility and viability. Lead acetate treatment, induced alteration in sperms with normal morphology together with reductions in the serum FSH, LH, testosterone, body and testicular weights. The concentration of 17β‐hydroxysteroid dehydrogenase was significantly reduced. Co‐administration of L‐carnitine significantly reduced testicular oxidative stress, improved sperm parameters, elevated serum FSH, LH and testosterone with an insignificant reduction in the testicular weight. The concentrations of 17β‐hydroxysteroid dehydrogenase and lactate dehydrogenase‐C were significantly improved by L‐carnitine. The overall results indicate that L‐carnitine is expected to improve the lead acetate‐induced male reproductive toxicity.

Abstract
PURPOSE Sperm DNA fragmentation is a major cellular mechanism underlying varicocele-related male infertility. However, the type of DNA fragmentation - whether oxidative or of another nature - remains unknown. Thus, the aim of this study was to evaluate single- and double-stranded sperm DNA fragmentation, and oxidative-induced sperm DNA damage in men with varicocele. MATERIALS AND METHODS A cross-sectional study was performed, including 94 normozoospermic adults, of which 39 men without varicocele (controls) and 55 men with varicocele grades II or III, uni- or bilaterally. All men collected semen by masturbation. After semen analysis, the remaining volume was used for evaluation of three types of sperm DNA damage: (i) total DNA fragmentation, using an alkaline comet assay, (ii) double-stranded DNA fragmentation, using a neutral comet assay, and (iii) oxidative DNA damage, using an alkaline comet assay associated with the DNA glycosylase formamidopyrimidine enzyme. In each assay, percentage of sperm with any degree of DNA fragmentation, and with high DNA fragmentation were compared between the groups using an unpaired Student's t test or a Mann-Whitney test. RESULTS The varicocele group presented a higher rate of sperm with fragmented DNA (both any and high DNA fragmentation), considering single-stranded DNA fragmentation, double-stranded DNA fragmentation, or a combination of both, as well as oxidative-induced DNA fragmentation. CONCLUSIONS Patients with varicocele have an increase in sperm DNA fragmentation levels, particularly in oxidative stress-induced sperm DNA damage.

Abstract
The aim of this study was to evaluate the response of donkey spermatozoa to oxidative stress induced by hydrogen peroxide, and to determine whether the presence of seminal plasma modulates the sperm response to that stress. Nine ejaculates were collected, extended in skim milk extender and split into two aliquots. Seminal plasma was removed from the first but not second aliquot. Samples were subsequently split into four aliquots supplemented with different concentrations of commercial hydrogen peroxide (0, 100 and 250µM and 50mM). Aliquots were incubated at 37°C under aerobic conditions and several sperm parameters, namely motility, viability, intracellular levels of peroxides and superoxides and mitochondrial membrane potential, were evaluated at 0, 1 and 3h. Exposure to hydrogen peroxide markedly decreased sperm motility but had much less of an effect on sperm viability, mitochondrial membrane potential and intracellular reactive oxygen species levels. A protective effect of seminal plasma against the loss of sperm motility was not apparent, but some kinetic parameters and relative levels of superoxides were better maintained when seminal plasma was present together with high concentration of hydrogen peroxide. In conclusion, oxidative stress induced by hydrogen peroxide reduces donkey sperm motility and has a less apparent effect on other sperm parameters. Finally, seminal plasma is only able to partially ameliorate the detrimental effect of this induced stress.

Abstract
OBJECTIVES Dutasteride-Tamsulosin (DUT-TAM), a drug of choice for the treatment of prostate enlargement (Benign Prostatic Hyperplasia, BPH) has been implicated in testicular toxicity. This study investigated the protective effect of morin, a plant-derived flavonoid on DUT-TAM-induced testicular toxicity in Wistar rat. METHODS Twenty-four male Wistar rats (110-140 g) were randomly divided into four treatment groups (n=6). Group A animals served as the control and were administered olive oil, Group B animals were administered 5.4 mg/kg b.w. of dutasteride + 3.4 mg/kg b.w of tamsulosin., Group C animals were administered 100 mg/kg b.w. of morin, while Group D animals were administered DUT-TAM (5.4 mg/kg b.w. of dutasteride + 3.4 mg/kg b.w. of tamsulosin) and morin (100 mg/kg b.w.). The administration lasted for two weeks. RESULTS DUT-TAM-induced abnormal sperm morphology (31.8%), significantly reduced (p<0.05) sperm count, sperm motility, live-dead sperm ratio, testicular superoxide dismutase (SOD), catalase, glutathione-S-transferase (GST) and acid phosphatase (ACP) activities, as well as the levels of ascorbic acid and reduced glutathione (GSH) which were ameliorated by co-treatment with morin. Also, DUT-TAM-induced increase in testicular malondialdehyde level and the activities of alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) and lactate dehydrogenase (LDH) were significantly reversed (p<0.05) by co-treatment with morin. CONCLUSIONS These results indicated the protective ability of morin against Dutasteride-Tamsulosin-induced testicular toxicity and oxidative stress.

Effect of Quercetin Supplementation in Extender on Sperm Kinematics, Extracellular Enzymes Release, and Oxidative Stress of Egyptian Buffalo Bulls Frozen-Thawed Semen. Front Vet Sci 2020; 7:604460. [PMID: 33381536 PMCID: PMC7768016 DOI: 10.3389/fvets.2020.604460] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 11/03/2020] [Indexed: 01/24/2023] Open
Abstract
Buffalo spermatozoa are more sensitive for cryopreservation compared to other species. This study aimed to evaluate the consequences of quercetin against cryodamage of buffalo frozen–thawed spermatozoa characteristics. Semen of Egyptian bulls (n = 4) was extended in OptiXcell extender incorporated with quercetin at 0 (control), 2.5, 5.0, 10.0, 20.0, 40.0, and 80.0 μM before cryopreservation. Frozen–thawed semen was evaluated for sperm motility by computer-assisted sperm analyzer (CASA), viability, morphology, membrane, and acrosome integrities. The kinematics parameters including average path velocity (VAP; μm/s), straight linear velocity (VSL; μm/s), curvilinear velocity (VCL; μm/s), amplitude of lateral head displacement (ALH; μm), beat cross frequency (BCF; Hz), linearity [LIN, (VSL/VCL) × 100], and straightness [STR, (VSL/VAP) × 100] were assessed. The sperm-free extender was evaluated for aspartate aminotransferase (AST), alanine aminotransferase (ALT), and H2O2. Homogenized sperm cells were evaluated for oxidative stress biomarkers [superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX)], and lipid peroxidation [malondialdehyde (MDA)]. The highest values of total motility, progressive motility, viability, intact acrosome, and membrane integrity substantially improved with 10 μM of quercetin. STR (%) was substantially low (P < 0.01), and VCL (μm/s) and ALH (μm) were markedly high (P < 0.05) in 10 μM of quercetin. The outflow of ALT enzyme to extracellular fluid was lower with 10 μM of quercetin (P < 0.001) and higher at 2.5 μM of quercetin. The spermatozoa leaked AST was markedly lower at 5.0, 10 (P < 0.001) and 20 μM (P < 0.05) of quercetin. The activity of antioxidant enzymes was eminently low at all quercetin concentrations, and this was accompanied by the decrease in H2O2 in the media. SOD activity at 10–80 μM, CAT at 5.0–40 μM, and GPX at 2.5–80.0 μM of quercetin in spermatozoa were substantially low. MDA level significantly (P < 0.001) decreased at all quercetin concentrations. In conclusion, the incorporation of quercetin at the level of 10 μM is promising in improving buffalo semen characteristics and lower the freezing–thawing oxidative stress.

Abstract
Owing to their tremendous potential, the inference of nano-scaled materials has revolutionized many fields including the medicine and health, particularly for development of various types of targeted drug delivery devices for early prognosis and successful treatment of various diseases, including the brain disorders. Owing to their unique characteristic features, a variety of nanomaterials (particularly, ultra-fine particles (UFPs) have shown tremendous success in achieving the prognostic and therapeutic goals for early prognosis and treatment of various brain maladies such as Alzheimer's disease, Parkinson's disease, brain lymphomas, and other ailments. However, serious attention is needful due to innumerable after-effects of the nanomaterials. Despite their immense contribution in optimizing the prognostic and therapeutic modalities, biological interaction of nanomaterials with various body tissues may produce severe nanotoxicity of different organs including the heart, liver, kidney, lungs, immune system, gastro-intestinal system, skin as well as nervous system. However, in this review, we have primarily focused on nanomaterials-induced neurotoxicity of the brain. Following their translocation into different regions of the brain, nanomaterials may induce neurotoxicity through multiple mechanisms including the oxidative stress, DNA damage, lysosomal dysfunction, inflammatory cascade, apoptosis, genotoxicity, and ultimately necrosis of neuronal cells. Our findings indicated that rigorous toxicological evaluations must be carried out prior to clinical translation of nanomaterials-based formulations to avoid serious neurotoxic complications, which may further lead to develop various neuro-degenerative disorders.

Overtime expression of plasma membrane and mitochondrial function markers associated with cell death in human spermatozoa exposed to nonphysiological levels of reactive oxygen species.

Abstract
In many cell types, the potential of reactive oxygen species to induce death processes has been largely demonstrated. Studies in spermatozoa have associated the imbalance of reactive oxygen species and phosphatidylserine externalisation as an apoptosis marker. However, the lack of consensus about time effect in the joint expression of these and other death markers has made it difficult to understand the set of mechanisms influenced beyond the concentration effect of reactive oxygen species to stimulate cell death. Here, the plasma membrane permeability and integrity, phosphatidylserine externalisation and mitochondrial membrane potential were jointly evaluated as death markers in human spermatozoa stimulated with H2 O2 . The results showed a profound and sustained effect of dissipation in the mitochondrial membrane potential and an increased phosphatidylserine externalisation in human spermatozoa exposed to 3 mmol-1 of H2 O2 at 30 min. This was followed by an increased membrane permeability after 45 min. The last observed event was the loss of cell membrane integrity at 60 min. In conclusion, mitochondria are rapidly affected in human spermatozoa exposed to reactive oxygen species, with the barely detectable mitochondrial membrane potential coexisting with the high phosphatidylserine externalisation in cells with normal membrane permeability.

Abstract
BACKGROUND Higher concentrations of seminal reactive oxygen species may be related to male infertility. Astaxanthin with high antioxidant activity can have an impact on the prevention and treatment of various health conditions, including cancer. However, efficacy studies on astaxanthin in patients with oligospermia with/without astheno- or teratozoospermia (O±A±T) have not yet been reported. Our aim was to evaluate the effect of the oral intake of astaxanthin on semen parameters. PATIENTS AND METHODS In a randomized double-blind trial, 80 men with O±A±T were allocated to intervention with 16 mg astaxanthin orally daily or placebo. At baseline and after three months basic semen parameters, sperm deoxyribonucleic acid (DNA) fragmentation and mitochondrial membrane potential (MMP) of spermatozoa and serum follicle-stimulating hormone (FSH) value were measured. RESULTS Analysis of the results of 72 patients completing the study (37 in the study group, 35 in the placebo group) did not show any statistically significant change, in the astaxanthin group no improvements in the total number of spermatozoa, concentration of spermatozoa, total motility of spermatozoa, morphology of spermatozoa, DNA fragmentation and mitochondrial membrane potential of spermatozoa or serum FSH were determined. In the placebo group, statistically significant changes in the total number and concentration of spermatozoa were determined. CONCLUSIONS The oral intake of astaxanthin did not affect any semen parameters in patients with O±A±T.

Abstract
The objective of this study was to ascertain the cellular and functional parameters as well as ROS related changes in sperm from bulls with varied sperm freezability phenotypes. Using principal component analysis (PCA), the variables were reduced to two principal components, of which PC1 explained 48% of the variance, and PC2 explained 24% of the variance, and clustered animals into two distinct groups of good freezability (GF) and poor freezability (PF). In ROS associated pathophysiology, there were more dead superoxide anion positive (Dead SO+) sperm in GF bulls than those in PF (15.72 and 12.00%; P = 0.024), and that Dead SO+ and live hydrogen positive cells (live H2O2+) were positively correlated with freezability, respectively (R2 = 0.55, P < 0.0130) and (rs = 0.63, P = 0.0498). Related to sperm functional integrity, sperm from PF bulls had greater dead intact acrosome (DIAC) than those from GF bulls (26.29 and 16.10%; P = 0.028) whereas sperm from GF bulls tended to have greater live intact acrosome (LIAC) than those from PF bulls (64.47 and 50.05%; P = 0.084). Sperm with dead reacted acrosome (DRAC) in PF bulls were greater compared to those in GF (19.27 and 11.48%; P = 0.007). While DIAC (R2 = 0.56, P = 0.0124) and DRAC (R2 = 0.57, P < 0.0111) were negatively correlated with freezability phenotype, LIAC (R2 = 0.36, P = 0.0628) was positively correlated. Protamine deficiency (PRM) was similar between sperm from GF and PF bulls (7.20 and 0.64%; P = 0.206) and (rs = 0.70, P = 0.0251) was correlated with freezability. Sperm characteristics associated with cryotolerance are important for advancing both fundamental andrology and assisted reproductive technologies across mammals.

Abstract
The present study explored the effect of anandamide supplementation in the extender on quality of low sperm doses during cryopreservation in Sahiwal bulls. Each fresh semen sample was split into eight aliquots (I, II, III, IV, V, VI, VII and VIII). The aliquots I, II, III and IV were taken as control and diluted to 20, 15, 10 and 5 million spermatozoa/0.25 ml respectively. The aliquots V, VI, VII and VIII were diluted with extender (supplemented with anandamide at 1 µM/ml of extender) to 20, 15, 10 and 5 million spermatozoa/0.25 ml respectively. This was followed by filling of diluted semen into French mini straws, equilibrated at 4°C of 4 hr and cryopreserved. The results revealed that the proportions of motile spermatozoa, live spermatozoa and live acrosome intact spermatozoa were significantly (p < .05) higher in all anandamide-treated sperm doses compared to control. The proportions of moribund spermatozoa, dead acrosome intact spermatozoa and capacitated spermatozoa were significantly (p < .05) reduced in all anandamide-treated sperm doses compared to control, with no difference in proportion of dead acrosome-reacted spermatozoa. In conclusion, anandamide supplementation in the extender increases the post-thaw quality of low sperm doses during cryopreservation in bulls.

Abstract
OBJECTIVE Chronic exposure to fluoride causes tissue damage induced by oxidative imbalance, Cyperus esculentus (CE) possess anti-inflammatory and immunostimulatory properties. This study focused on Salutary role of Cyperus esculentus in sodium fluoride (NaF) induced testicular degeneration and sperm quality deteriorations. METHODS Sexually mature male Sprague-Dawley rats were randomly divided into four groups (n=6). Animals in control group received 2 mls of normal saline per day; CE group received 500mg/kg bw of CE; NaF group received 5mg/kg bw of NaF; NaF+CE group received 500mg/kg bw of CE (for 14 days pre-treatment) and NaF co-treatment till 56 days via gastric gavage. Parameters tested include: testicular histology, sperm parameters, sex hormone, fertility test, malondialdehyde (MDA), superoxide dismutase (SOD), reduced glutathione, glutathione peroxidase (GPX), catalase (CAT), testicular fluoride and testicular cholesterol. RESULTS Sodium fluoride significantly (p<.05) decrease testicular antioxidant (SOD, CAT, GSH and GPx), sperm quality, hormone profiles (TT, FSH, LH, estrogen levels), testicular cholesterol, morphometric parameters, Johnsen's Score and number of implantations in female rats with corresponding (p<.05) increase in oxidative stress makers and abnormal sperm morphology. Also depleted seminiferous epithelium and degenerate spermatogenic cells. Pretreatment with 500mg/kg bw of CE lowered NaF toxicity by significantly reducing the lipid peroxidation products, fluoride accumulation in the testis, histopathological changes of the testes and spermatozoa abnormalities and reverted observed NaF-induced inhibition in antioxidant parameters and weight of accessory sex organs. CONCLUSIONS Cyperus esculentus attenuated NaF-induced testicular injuries and protected the seminiferous epithelium, reduced oxidative stress and promoted spermatogenesis.

Abstract
Elevated levels of reactive oxygen species can cause oxidative stress, which could lead to membrane damage, decreased fertility, and spermatozoan morphological deformities. Antioxidants can be supplemented to reduce the impacts of oxidative stress. The objective of this study was to determine the effects of supplementing quercetin (0.25, 0.50, 0.75 mM) during the thawing and incubation of frozen-thawed boar semen on spermatozoan characteristics, IVF kinetics (n = 400) and subsequent embryonic development (n = 1340). Spermatozoa were evaluated for motility, viability, and membrane lipid peroxidation levels at 0, 2, 4, 6, 8, and 10 h after thawing. Embryos were evaluated for IVF kinetics 12 h after IVF (penetration, polyspermy, male pronucleus formation, IVF efficiency) and cleavage and blastocyst formation at 48 h and 144 h after IVF, respectively. Spermatozoa supplemented with 0.25 mM quercetin had significantly higher (P < 0.05) motility (51.67±8.50 %) and percent of viable cells (61.21 ± 2.44 %) compared to all other treatments at 10 h after thawing, in addition to having significantly (P < 0.05) lower levels of hydroperoxide (3.38 ± 0.88 μM/107cells). There were no differences in penetration rates and male pronucleus formation between treatment groups. Supplementation of quercetin significantly decreased (P < 0.05) polyspermy and significantly increased (P < 0.05) the percentage of embryos reaching blastocyst stage of development by 144 h after IVF compared to no supplementation. Results indicated that supplementing frozen-thawed boar semen with 0.25 mM quercetin improves sperm characteristics up to 10 h after thawing and decreases polyspermy while improving early embryonic development in pigs.

Abstract
Semen samples are known to contain abnormal amounts of reactive oxygen species (ROS) and oxygen free radicals; therefore, the identification of antioxidant molecules able to counteract the oxidative damage caused by ROS is foresight. Indeed, improving semen quality in terms of motility and reduction in DNA damage, can significantly improve the fertilization potential of sperm in vitro. To this regard, myo-inositol, based on its antioxidant properties, has been reported to be effective in improving sperm quality and motility in oligoasthenozoospermic patients undergoing assisted reproduction techniques when used as a dietary supplementation. Moreover, in vitro treatment demonstrated a direct relationship between myo-inositol, mitochondrial membrane potential and sperm motility. This experimental study aimed to evaluate the effects of myo-inositol (Andrositol-lab) in vitro treatment on sperm motility, capacitation, mitochondrial oxidative phosphorylation and DNA damage. Our results demonstrate that myo-inositol induces a significant increase in sperm motility and in oxygen consumption, the main index of oxidative phosphorylation efficiency and ATP production, both in basal and in in vitro capacitated samples. Moreover, we provide evidence for a significant protective role of myo-inositol against oxidative damage to DNA, thus supporting the in vitro use of myo-inositol in assisted reproductive techniques. Even if further studies are needed to clarify the mechanisms underlying the antioxidant properties of myo-inositol, the present findings significantly extend our knowledge on human male fertility and pave the way to the definition of evidence-based guidelines, aiming to improve the in vitro procedure currently used in ART laboratory for sperm selection.

Abstract
Most aspects of reproductive function including spermatogenesis, oocyte growth and maturation, early embryonic development, fetal and placental growth, and lactation can be affected by thermal stress. Furthermore, it has been shown that oxidative stress involves in the pathology of thermal stress. Therefore, the aim of this study was to investigate the impacts of thermal stress on the ovine mature epididymal spermatozoa extracted from testes of slaughtered rams in the presence or absence of an antioxidant. Epididymal spermatozoa were incubated at scrotal (32.00 ˚C), normal body (39.00 ˚C), and hyperthermic temperatures (41.00 ˚C) for 4 hr in the presence or absence of 1 mmol L-1 β-mercaptoethanol. The results demonstrated the high sensitivity of ram epididymal spermatozoa to the hyperthermic temperature at in vitro conditions. In comparison with scrotal temperature, quality parameters of spermatozoa were negatively affected by increase in temperature, as such in the spermatozoa incubated at hyperthermic temperature significant decrease was observed in the viability, DNA integrity and in the majority of motility parameters. Moreover, concentration of lipid peroxidation by-products, thiobarbituric acid reactive substances, were significantly increased. The findings showed that using antioxidant during incubation period had significant protective effect on the viability and motility of incubated spermatozoa not only at the hyperthermic temperature, but also at the scrotal and normal body temperatures. In conclusion the ovine epididymal spermatozoa were sensitive to in vitro thermal stress and it seems that this sensitivity was partly related to the oxidative stress.

Abstract
Introduction: Morphine (MOR) as a psychoactive agent in the opium family causes free radicals accumulation which leads to failure in spermatogenesis. Gallic acid (GA), a polyphenolic acid, is found in various plants with antioxidant, anti-fungal, anti-viral, and anti-allergic activities. The purpose of this study was to evaluate the effects of GA against MOR-induced damage to the reproductive parameter of rats. Methods: Sixty-four male Wistar rats (8 weeks, 220-250 g) were categorized into 8 groups by random (n=8/each); normal control and MOR control groups; GA groups (5, 10, 20 mg/kg) and MOR + GA groups (5, 10, 20 mg/kg). Treatments were administered intraperitoneally (i.p), daily for 4 weeks. The sperm parameters, spermatogenesis index (SI), total antioxidant capacity, testosterone level, and seminiferous tube diameter (STD) were assessed. Results: All sperm parameters reduced significantly in the MOR control group than to the normal control group (P < 0.01). All parameters were significantly improved in GA and GA + MOR treatment groups compared to the MOR control group (P < 0.01). Conclusion: MOR caused a detrimental effect on male reproductive parameters. Also, no significant modifications were observed in all doses of GA treatments in comparison with the normal control group. GA compensates the toxic effect of MOR on reproductive parameters. Hence, GA administration is beneficial in MOR users.

Abstract
BACKGROUND Progression of diabetes mellitus has increasingly led to several diabetic complications. Diabetes is one of the major factors implicated in male reproductive system damage. Recent approaches such as the use of medicinal plants have been explored in the management of diabetes and associated complications. Anchomanes difformis (common name: children's umbrella) has been shown to possess anti-diabetic ability in animal model. Therefore, this study seeks to investigate the potency of Achomanes difformis in ameliorating diabetes-induced reproductive dysfunction. METHODS Type 2 diabetes was induced in male Wistar rats with 10% fructose administration for 2 weeks and an intraperitoneal injection of 40mg/kgBW of streptozotocin. Aqueous extract (200mg and 400mg/kgBW) of Anchomanes difformis leaves was administered daily for 6 weeks. The rats were randomly divided into 7 groups with a minimum of eight rats in each (8 rats in normal groups and 10 in diabetic groups). The impact of diabetes and treatment was investigated by estimating sperm concentration, motility indices, viability and morphological parameters in the normal, treatment controls and diabetic rats using CASA-SCA system. Histological examination of the testes and epididymis was performed. RESULTS Diabetes induction resulted in significant decrease in sperm concentration, viability and some motility parameters with 40% abnormalities in sperm morphology. The administration of Anchomanes difformis significantly increased sperm concentration and sperm viability, while it significantly improved the percentage of morphologically normal sperm in diabetic rats. Anchomanes difformis ameliorated testicular damage such as vacuolization and loss of germinal epithelium in the diabetic-treated rats when compared to the diabetic controls. CONCLUSION The potency Anchomanes difformis displayed against diabetic-induced damage in the reproductive system might be a new and promising tool in the management of male reproductive dysfunctions and associated complications in diabetes mellitus.

Abstract
Background Nitrosamines as a carcinogenic agent has unfavorable effects on some of the male reproductive parameters. Pentoxifylline (PX) is a xanthine derivative used as a drug inhibiting the inflammatory factors, reducing blood viscosity, improving peripheral blood flow, and so on.
Objective: The aim of the present study is to evaluate the effects of PX against Dimethyl nitrosamine (DMN)-inducing the damage to the reproductive parameter of male rats. Materials and Methods In this experimental study, 48 male Wistar rats (8 wk, 220-250 gr) were randomly assigned to eight groups (n = 6/each): normal control and DMN control groups (40 mg/kg); PX groups (25, 50, 100 mg/kg), and DMN + PX groups (25, 50, 100 mg/kg). Treatments were administered intraperitoneally and the gavage applied daily for 28 days. The sperm parameters, spermatogenesis index, total antioxidant capacity, testosterone level, and seminiferous tube diameter were assessed. Results The values of all parameters reduced significantly in the DMN control group compared to the normal control group (p < 0.001). The PX and PX + DMN treatments at all entirely doses improved all parameters significantly compared to the DMN control group (p < 0.001). Conclusion DMN caused detrimental effects on reproductive parameters. Also, no significant modifications were observed in PX treatments at all doses compared to the normal control group. PX compensated the toxic effect of DMN on reproductive parameters.

Abstract
The aim of this study was to elucidate the beneficial effects of green tea extract (GTE) in tris citric acid extender on post thaw structural and functional characteristics, DNA fragmentation (%), total antioxidant capacity (TAC, μM/L), lipid peroxidation (LPO, μM/mL) levels and in vivo fertility of buffalo (Bubalus bubalis) bull spermatozoa. GTE is a acknowledged natural antioxidant, act as a free radical scavenger and protects spermatozoa against oxidative stress. Three mature and donor buffalo bulls were used in this experiment. Two ejaculates were collected per bull on each collection day, followed by initial evaluation for consistency (colour), volume (mL), progressive motility and concentration (x109) and were diluted in five extenders @ 50 x 106/ mL (C = control, no GTE; T1 = treatment 1, GTE 0.1%; T2 = treatment 2, GTE 0.5%; T3 = treatment 3, GTE 0.75% and T4 = treatment 4, GTE1.0%). The experiment was repeated thrice. Data analysis showed that sperm progressive motility (%), plasma membrane integrity (%), supravital plasma membrane integrity (%), viable sperm with intact acrosome (%) and TAC were significantly higher (P < 0.05) in extender supplemented with T4 as compared to control. Furthermore, sperm DNA fragmentation and occurrance of LPO in buffalo bull spermatozoa were significantly lowered in T4 than control. In vitro longevity (%) of spermatozoa was significantly higher in T4 compared to control during 45 and 90 min of incubation at 37 °C. In vivo fertility rate of buffalo bull spermatozoa was significantly higher in T4 compared to control (64.96 vs. 48.40%, P < 0.05). It is concluded that supplementation of tris citric acid extender with 1.0% GTE improved structural and functional characteristics, TAC, in vitro longevity (%) and in vivo fertility, whereas decreased DNA fragmentation and LPO occurrence in buffalo bull spermatozoa after freezing and thawing protocol.

Abstract
In order to add information to physiology of sperm maturation and help to underline future antioxidant supplementation treatment to epididymal sperm, the aim of this study was to evaluate susceptibility of caput, corpus and cauda epididymal sperm to different reactive oxygen species (ROS) in dogs. Epididymal sperm was separately collected from each segment (caput, corpus and cauda) and subjected to 4 different ROS-challenges: superoxide anion, hydrogen peroxide, hydroxyl radical, malondialdehyde (MDA) or maintained as control. After 30 min of incubation in each ROS, sperm was evaluated for sperm kinetics, plasma and acrossomal membrane integrity, mitochondrial activity and resistance to oxidative stress. Decreased total and progressive sperm motility and rapid velocity at epididymal corpus occurred after exposure to hydrogen peroxide, hydroxyl radical and MDA. However, for cauda epididymis, hydrogen peroxide and malondialdehyde promoted higher deleterious effect regarding sperm motility and velocity. Only at cauda epididymis MDA decreased sperm mitochondrial activity index and no kinetics alterations (motility or velocity) occurred after exposure to superoxide anion in corpus and cauda epididymis. In conclusion, corpus and cauda epididymal sperm are highly susceptible to deleterious effect of hydrogen peroxide, malondialdehyde and hydroxyl radical. In addition, epididymal canine sperm is relatively resistant to superoxide anion damage.

Abstract
Diabetes-induced male sexual dysfunction is associated with endothelial dysfunction. Inhibition of soluble epoxide hydrolase (sEH) is known to improve endothelial function in diabetes. Therefore, we hypothesized that sEH inhibitor (sEHI), [trans-4-{4-[3-(4-trifluoromethoxyphenyl)-ureido]cyclohexyloxy}benzoic acid] / t-TUCB can restore the male sexual function in diabetic rat. After one week of administration of diabetogenic agent STZ (52 mg/kg i.p) injection, diabetic rats were treated with t-TUCB (0.1 and 0.3 mg/kg, p.o) or vehicle for 8 weeks. The sexual behaviour parameters of the animals were evaluated at the end of dosing period. The levels of testosterone and glucose in serum, and sperm were quantified. Effect of treatment on weight of reproductive organs and histopathology of penile tissue was evaluated. Diabetes had a negative effect on male sexual function, weight of sexual organs and production of sperm with a parallel decrease in the level of testosterone. The sEHI, t-TUCB, significantly preserved the sexual function and minimized an increase in the level of blood glucose in diabetic rats. It also prevented a decrease in the level of testosterone and sperm in diabetic rats, in comparison to diabetic control rats. Further, diabetes induced distortion of corpus cavernosum was attenuated by t-TUCB. Based on our findings, sEHI may delay the development of sexual dysfunction in diabetes.

Abstract
Copper (Cu) is one of the most widespread environmental pollutants and is known to exert multiple toxic effects including reproductive toxicity. In this study, we investigated the toxic effect of Cu on reproduction of the red swamp crayfish (Procambarus clarkii), an economic crustacean species, by exposing adult male crayfish to 0.03 and 3.00 mg/L Cu2+ for 7 days. The results showed that Cu2+ exposure induced oxidative stress accompanied by elevated reactive oxygen species (ROS) and malondialdehyde (MDA) levels in testes, and resulted in decreased sperm quality and abnormal testicular structures with apoptotic germ cells and vacuolisation in Sertoli cells. To reveal the molecular mechanism of Cu2+-induced oxidative damage in crayfish testes, we sequenced, assembled and annotated the transcriptome for crayfish testes, using the Illumina sequencing approach. After the 3.00 mg/L Cu2+ treatment, 6745 genes with differentially expressed profile were identified, of which many genes were involved in cellular response to ROS based on Gene Ontology enrichment analysis. Further, KEGG analysis demonstrated that genes with up-regulated expression levels significantly enriched in mitochondria oxidative phosphorylation pathway, suggesting disturbed mitochondrial electron transport chain was probably a main source of Cu2+-induced ROS production in testes. This study represented the first use of transcriptome to investigate the toxic effect of Cu2+ on male crayfish reproduction, and the pathways identified underlying Cu2+ toxicity at molecular level provide a novel insight into the reproductive toxicity of Cu in crustaceans.

Abstract
Objective: To determine the impact of walnut oil on nitrite-induced testicular toxicity
in Sprague-Dawley (SD) rats. Available evidence suggests that walnut oil
contains high levels of important unsaturated fatty acids including
alpha-linolenic acid (ALA) and omega-3; nitrite is a reproductive toxicant
that causes the loss of germ cells in the seminiferous tubules and generates
oxidative stress in the testes, thus reducing sperm counts and affecting
sperm morphology. Methods: This study included 24 male and 24 female adult SD rats. The male rats
randomly assigned to Group A (controls) were given normal saline 2 ml/kg.
The rats in Groups B, C, and D were given 50mg/kg body weight (bwt) of
walnut oil, 0.08 mg/kg bwt of nitrite, and 0.08 mg/kg bwt of nitrite + 50
mg/kg of walnut oil respectively for 28 days via gastric gavage. Tested
parameters included: testicular histology, sperm parameters, reproductive
hormones, fertility, malondialdehyde (MDA), superoxide dismutase (SOD),
reduced glutathione, and catalase (CAT). Results: A severe decrease in spermatogenic cell series, hypocellularity, tubular
atrophy, decreased sperm quality, and increased MDA levels were observed in
the rats given nitrite only when compared to controls. Rats given 50 mg/kg
of walnut oil had significant growth of seminiferous epithelium compared to
controls. The rats given walnut oil and nitrite had significant growth of
seminiferous epithelium, improved sperm quality, and had decreased MDA
levels. Conclusion: Walnut oil attenuated the deleterious effects of nitrite to the testes,
reduced oxidative stress, and promoted spermatogenesis.

Abstract
The cross-sectional study aimed to assess whether oxidative stress induced by exposure to polycyclic aromatic hydrocarbons (PAHs) affect semen quality and sperm DNA integrity. A total of 106 who met the inclusion criteria, were recruited from a coke-oven plant during their annual health checkup. The human subjects were grouped into the high exposure group, the low exposure group and the control based on PAH concentrations surrounding their employment locations. Semen quality, oxidative stress status, and sperm DNA damage [DNA fragmentation and 8-hydroxy-2'-deoxyguanosine (8-oxodGuo)] were assessed. Urinary 1-hydroxypyren (1-OHP) was used to assess human subject exposure to PAHs. The high exposure group experienced significantly lower sperm motility and normal morphology than the control (P = 0.046 and 0.049, respectively). The high exposure group also had significantly higher 8-oxoGuo concentrations in sperm than the control (P = 0.027). Urinary 1-OHP concentration was associated with decreased motility and less normal morphology, along with increased sperm oxidative damage and ROS concentrations. Oxidative stress induced by exposure to PAHs was associated with decreased sperm quality.

Abstract
Models of ageing predict that sperm function and fertility should decline with age as sperm are exposed to free radical damage and mutation accumulation. However, theory also suggests that mating with older males should be beneficial for females because survival to old age is a demonstration of a male's high genetic and/or phenotypic quality. Consequently, declines in sperm fitness may be offset by indirect fitness benefits exhibited in offspring. While numerous studies have investigated age-based declines in male fertility, none has taken the integrated approach of studying age-based effects on both male fertility and offspring fitness. Here, using a cohort-based longitudinal study of zebrafish (Danio rerio), we report a decline in male mating success and fertility with male age but also compensating indirect benefits. Using in vitro fertilization, we show that offspring from older males exhibit superior early survival compared to those from their youngest counterparts. These findings suggest that the high offspring fitness observed for the subset of males that survive to an old age (approx. 51% in this study) may represent compensating benefits for declining fertility with age, thus challenging widely held views about the fitness costs of mating with older males.

Abstract
Objective The current study focused on the pro-fertility potential of Senecio
biafrae (Sb) extract and vitamin C in Male Sprague Dawley (SD)
rats with tetracycline-induced infertility. Methods A total of 36 male and 36 female adult SD rats were used for this
investigation. The male rats randomly assigned to Group A (controls) were
given normal saline 2ml/kg. Rats in Groups B, C, D, E, and F were
respectively administered [30 mg/kg of body weight (bwt) of
tetracycline], [30 mg/kg bwt of tetracycline + 50 mg/kg of
vitamin C], [30 mg/kg bwt of tetracycline + 500 mg/kg bwt of
Sb], [30 mg/kg bwt of tetracycline + 50
mg/kg of vitamin C + 500 mg/kg bwt of Sb], and
[30 mg/kg bwt of tetracycline reversal] daily for 28 days via
gastric gavage. Tested parameters included sperm parameters, hormonal
profile, histology, and fertility test. Results Significant (p<0.05) increases were seen in sperm
quality, hormone profile, organ and body weights of the groups treated with
vitamin C, Sb, and tetracycline. There was derangement in
sperm quality, hormone profile, and organ and body weight of the animals in
group B. Histoarchtecture of the testes showed normal cellular composition
in the germinal epithelium with sperm cells in the lumen and normal
interstitium in groups A, C, D, and E. Group F showed abnormal
spermatogenesis and poor association of spermatogenic cells, however there
was depletion in the seminiferous epithelium in the group treated with
tetracycline. Conclusion Senecio biafrae defeated the deleterious effects of
tetracycline on the male reproductive system of rats treated with the
drug.

Abstract
Although equal numbers of X and Y spermatozoa are produced during spermatogenesis, the sex chromosome ratio in ejaculated spermatozoa can be altered by exposure to endocrine-disrupting chemicals (EDCs), which can be reflected by altered sex ratios at birth. Here, we hypothesized EDCs affect sperm functions and viability of X and Y chromosome-bearing human spermatozoa. After exposure to genistein (Gen), bisphenol A (BPA), 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), dibromochloropropane (DBCP), and diazinon (Diaz), we evaluated motility, viability, capacitation, and differential viability of X and Y spermatozoa. All EDCs tested altered sperm viability, motility, and capacitation. Interestingly, the Y/X ratio of live spermatozoa was significantly lower in sperm treated with TCDD, DBCP, and Diaz than control spermatozoa. Our results suggest that some of EDCs have larger effects on the viability of Y spermatozoa than X spermatozoa, implicating that a reduction in Y sperm viability may result in a female-biased sex ratio of offspring at birth.

Abstract
OBJECTIVE To evaluate storage time effects in cryopreserved human semen samples, kept in the freezer at a controlled temperature of -80°C, on sperm viability after thawing. METHODS We used 20 semen samples. Each sample was cryopreserved in 10 fingers, which were divided into five groups: one group was kept in cryogenic canisters throughout the experiment(control), and four groups were kept in a VIP Ultra Low MDF-U76V- PE freezer, with the temperature set at -80°C, for 24, 48, 72 and 96 hours, respectively. After the exposure time, the samples were stored in cryogenic canisters after being thawed. The analyzed parameters were: motility, vitality and mitochondrial activity. RESULTS After thawing, we noticed decreased sperm motility, vitality and mitochondrial activity, when comparing the tested groups with the control group, as well as a progressive reduction in the analyzed parameters between the times evaluated. CONCLUSIONS Cryopreservation of semen samples at -80°C is potentially harmful to sperm viability, causing damage when submitted to longer exposure times.
