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 ethanoland 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. Key words: Ethanol, Sperm parameters, Vitamin E.

Factors Affecting

BACKGROUND: One of the main factors affecting male infertility is DNA fragmentation in sperm. Male infertility is a heterogeneous group of disorders, known causes account for only 30-50%, and unknown cause (idiopathic) constitute the rest. Infertility involves nearly 15% of couples in the reproductive age, and only the male problem involves about 40% of the problems.AIM: We have studied our DNA damage to sperm cells of a group of infertile males (113 patients) with abnormal sperm parameters (oligoasthenospermia and oligospermia) and a group of male patients (80 patients) with normal semen parameters (normospermia) to document whether the Sperm Chromatin Dispersion (SCD) analysis could increase the information obtained from the sperm routine analysis to explain the causes of infertility.MATERIALS: A group of 193 patients were analysed, 113 patients in the working group and 80 patients in the control group were screened. The ejaculate samples were taken by the patient to whom the reason for the analysis was explained. All patients were from the Republic of Kosovo. Samples are collected from 2014/2018. Sperm Chromatin Dispersion (SCD) analyses in the ejaculate were analysed by the Biolab Zafi laboratory in Peja.RESULTS: Clinical data were compared between the two groups by one-way ANOVA, mean ± SD, student's t-test. A p-value of less than P < 0.05% was considered statistically significant. Outcomes: In our study, we have gained significant (P < 0.05) results in the workgroup and the control group across all hormonal parameters, sperm parameters, and fragmented DNA in the sperm.CONCLUSION: Based on our obtained results we can conclude that DNA fragmentation in spermatozoa is useful in the selection of unsuitable DNA sperm for use in ART methods. We conclude that our DNA fragmentation analysis results are encouraging and can be used for diagnostic purposes in determining male infertility.

Background: Some plants stimulate spermatogenesis and increase fertility, while some cause spermatogenesis arrest. So far, the effects of bene (Pistacia atlantica) on male fertility have not been studied. The aim of this study was to investigate the effects of bene on sperm parameters, testicular histopathology, sperm quality, and oxidative stress in busulfan-induced infertile mice. Methods: Thirty-five male BALB/c mice were randomly assigned to control, sham, busulfan, bene, and bene + busulfan groups. The busulfan group received 10 mg/kg as a single dose and intraperitoneally. The bene group received pellets containing 10% of bene. Another group received 10 mg/kg busulfan and was fed with pellet containing 10% bene. Then, sperms, sperm chromatin quality, testicular histopathology, and oxidative stress levels were studied on the 35th day of the experiment. Results: Busulfan injection resulted in a significant reduction in sperm parameters compared to the control group (p<0.001); it decreased after bene administration (p<0.001). In addition, in the group treated with bene, the sperm count with damaged DNA was reduced and the level of malondialdehyde decreased compared to the busulfan group. A significant increase was observed in the mean level of superoxide dismutase and catalase enzymes in the bene + busulfan group compared to the busulfan group (p<0.001). The histopathological improvement of the testis was observed in the bene + busulfan group. Conclusion: The administration of 10 mg/kg of bene powder for 35 days reduced the oxidative stress, improved testicular histopathology, sperm chromatin quality, and sperm parameters in the infertile mice model.

Objective: The present study investigated sperm chromatin quality and testosterone levels in acrylamide-treated mice and the possible protective effects of vitamin E on the fertility potential of spermatozoa. Methods: Thirty-two adult male mice were divided equally into four groups. Group 1 was the control, group 2 received acrylamide (10 mg/kg, water solution), group 3 received vitamin E (100 mg/kg, intraperitoneal), and group 4 received both acrylamide and vitamin E. After 35 days, spermatozoa from the right cauda epididymis were analyzed in terms of count, motility, morphology, and viability. Sperm DNA integrity and chromatin condensation were assessed by acridine orange (AO), aniline blue (AB), toluidine blue (TB), and chromomycin A3 (CMA3) staining. Results: In acrylamide-treated mice, significantly lower sperm concentration, viability, motility, and testosterone levels were found in comparison with the control and acrylamide+vitamin E groups (<i>p</i><0.05). In the vitamin E group, significantly more favorable sperm parameters and testosterone levels were found than in the other groups (<i>p</i><0.05). There were also significantly more spermatozoa with less condensed chromatin in the acrylamide-treated mice than in the other groups. Moreover, significantly more spermatozoa with mature nuclei (assessed by AB, CMA3, AO, and TB staining) were present in the vitamin E group than in the control and acrylamide+vitamin E groups. Conclusion: This study revealed the deleterious effects of acrylamide on sperm parameters and sperm chromatin quality. Vitamin E can not only compensate for the toxic effects of acrylamide, but also improve sperm chromatin quality in mice.

Background: Obesity is a prevailing metabolic disorder that affects the functioning of the male reproductive system. Excessive adipose tissue enhances reactive oxygen species generation and is linked with male infertility. Spinach has demonstrated antioxidant effects. The present study was conducted to determine the antioxidant effects of spinach on sperm parameters in obese Sprague Dawley rats. Subjects and methods: This randomized control study was conducted at the animal house of the National Institute of Health Islamabad, Islamic International Medical College, Cosmesurge International Hospital, Rawalpindi, and Apollo lab, Islamabad, Pakistan from April 2016 to March 2017. Forty male Sprague Dawley rats having an age of 8 weeks and weight 160-200g were tagged from number 1 to 40. Every third rat was randomly allocated to control Group A (n=13) and remaining into the Experimental group (n=27). Rats of control Group A was given a standard diet while a high-fat diet was given to Experimental group rats to induce obesity for the duration of six weeks. Weight (g) was measured weekly and obesity was confirmed when rats attain more than 20% weight when compared with that of rats of control Group A. Then, after obesity induction, the experimental group was alienated into the obesity control group (Group B) and spinach treated group (Group C). For sample, rats of Group A and Group B were sacrificed, and the cauda epididymis of each rat was placed in a Petri dish containing normal saline and cut into pieces to allow the release of sperm and then sperm parameters (sperms concentration, motility, and morphology) were recorded under the microscope. Then, spinach (5% hot water extract) along with the persistence of fat diet was administered to Group C for 4 weeks and finally, sperm parameters were measured in this group. Results: Sperm concentration/ml, motility (%), and normal morphology (%) of Group B rats were significantly decreased as compared to Group A rats. However, sperm concentration/ml, motility (%), and normal morphology (%) of Group C (spinach treated group) rats was significantly increased (p<0.001) as compared to Group B (obesity control group) rats after administering spinach. Conclusion: The addition of Spinach in a normal diet regimen restores normal sperm morphology, improves sperm motility and concentration.

Purpose This paper aims to design to evaluate the protective effect of vitamin E to ameliorate the disturbances in testosterone pathway and sperm quality of male rats induced by the glycosides vicine (V) and convicine (C) of Vicia faba. Design/methodology/approach Forty male albino rats were divided into five equal groups; control, paraffin oil, V (400 mg/kg) C (150 mg/kg)-treated group, vitamin E (100 mg/kg) + VC-treated group, and vitamin E (200 mg/kg) + VC-treated groups which injected intraperioneally (IP) with 0.5-ml saline, 0.5-ml paraffin oil,V (400 mg/kg) and C (150 mg/kg) of Vicia faba, vitamin E (100 mg/kg) + VC-treated groups, and Vitamin E(200 mg/kg) + VC-treated groups, respectively. Blood and testicular tissue were obtained after one month of the study. The male genital organs were calculated. Testosterone (Ts), luteinizing hormone (LH), follicle stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEA-SO4), sex hormone binding globulin (SHBG),?-glutamyl transpeptidase (?-GT), glucose-6-phosphate dehydrogenase (G6PD), 3ß-hydroxysteroid dehydrogenase (3ßHSD), lactate dehydrogenase (LDH), spermatozoa concentration, percent of mortality and abnormal sperms were evaluated. Findings The VC-treated group showed significant decrease (p < 0.01) in Ts, DHEA-SO4, G6PD, spermatozoa number and mortality percent, as well as, the male genital organs (testes, epidydemis, seminal vesicle, prostate and vasa deferentia) while significant increase (p < 0.01) was found in LH, FSH, SHBG, LDH, ?-GT, sperms monoclonal Ki-67, and abnormal spermatocytes levels compared with control group. Vitamin E co-injection with VC-treated group returned all these parameters to the normal values. The higher dose of vitamin E (200 mg/kg) was more effect than the lower dose (100 mg/kg). Originality/value Vicia faba contains V and C glycosides. The V and C glycosides in Vicia faba are hydrolyzed by intestinal microflora to aglycones divicine and isouramil, respectively. Divicine and isouramil are highly reactive compounds generating free radicals where divicine and isouramil are the main factors of favism. The V and C glycosides induced disturbances in testosterone pathway and sperm quality of male rats and vitamin E ameliorates these disturbances.

Magnetic Activated Cell Sorting

Magnetic-activated cell sorting (MACS) has been used successfully in humans to remove apoptotic sperm from the ejaculate. Annexin V-conjugated microbeads recognise sperm with externalized phosphatidylserine, which is considered one of the features of apoptosis, and the labelled sperm is separated by MACS. The goals of the study were to determine if MACS can be used to separate apoptotic sperm from the ejaculate of stallions; and to determine if removal of apoptotic sperm improves the quality of stallion sperm. Our hypothesis was that MACS would improve semen quality by removing apoptotic sperm, resulting in samples with higher motility and viability. Two ejaculates from three different stallions of good fertility were used. Sperm were diluted with Tyrode’s albumin lactate pyruvate (TALP) and incubated with annexin V-conjugated microbeads for 15 min at 37°C. Control samples were incubated in the absence of annexin V microbeads. The suspension was then loaded into the separation column containing iron globes, which were fitted in a magnet (MiniMACS; Miltenyi Biotec Inc., Auburn, CA, USA). The effluent sample containing annexin-negative sperm was collected and then, the column was removed from the magnetic field and rinsed with TALP to collect the annexin-positive cells. Sperm viability, motility, morphology and caspase activation were determined in all three samples: control, annexin-negative, and annexin-positive. Data were evaluated by ANOVA and individual comparisons were performed by Tukey’s hsd test. Significance was set at P < 0.05 and data is presented as means ± SEM (Table 1). The main effect of stallion was significant only for sperm motility parameters. Sperm recovery rate following MACS was 46 ± 3%. In conclusion, the use of MACS was effective in removing apoptotic sperm from the ejaculate. The annexin-positive population displayed a higher proportion of sperm with activated caspases and lower membrane integrity and motility. However, removal of apoptotic sperm from the ejaculate did not improve sperm parameters in the annexin-negative group compared to control group. In addition, sperm morphology was not affected by MACS. Further studies are necessary to determine if MACS could be used successfully to improve sperm quality from subfertile stallions and frozen semen.

A 7-wk trial was carried out to investigate the effect of vitamin E and inorganic and organic selenium added to hens' diet on quality and lipid stability of eggs during storage. One hundred forty-four Hy-Line W-36 hens (63-wk of age) were divided into six equal groups. Five groups received a basal diet supplemented with 0.4 mg kg-1 sodium selenite or selenium yeast, 200 mg kg-1 vitamin E or a combination of selenium and vitamin E; whereas the control group received no supplementation. Hen production was assessed daily and fresh egg quality parameters were determined every 2 wk. Eggs were stored under different conditions (4°C, 23–27°C or 31°C) for 14 d. Eggs were analyzed for quality characteristics, egg component weight, Malondialdehyde values as a secondary oxidation product and yolk fatty acid (FA) composition. The performance of the hens and egg weights were not affected either by the source of the selenium or by the vitamin E. The inclusion of selenium or vitamin E in the diet significantly increased their concentrations in the egg. The supplemented diets also improved egg quality, oxidative stability and fatty acid composition during storage. Key words: Vitamin E, selenium, lipid peroxidation, egg fatty acid composition, storage

The aim of this study was to compare the possible protective effects of N-acetylcysteine (NAC), caffeic acid (CAPE) and vitamin E (Vit-E) on doxorubicin-induced hepatotoxicity. Thirty-two male Wistar albino rats, weighing between 250 and 350 g were supplied and randomly divided into five groups. Animals in study groups were pretreated with a single dose of doxorubicin (Dox), which was administered intraperitoneally (i.p.). Control group (Group I) was treated with intraperitoneal saline injection. Group II did not received any antioxidant agent after the injection. Group III and Group IV were given CAPE and intraperitoneal vitamin E injection for eight days, respectively. Group V received NAC for eight days. The study was finished after 10 days. Tissue samples were collected from all animals and histopathological examination was performed. There was statistically significant difference between the experiment groups and controls by means of mononuclear cell infiltration and diameters of hepatic sinusoid, terminal hepatic venule (central vein) and portal area (portal canal). Changes related with hepatocellular damage were more prominent, whereas there was no significant difference between Dox and NAC given groups histopathologically. It was observed that structural changes were regressed after CAPE administration. However, this recovery was more prominent in vitamin E given group. These findings suggest that Dox induced liver damage could be efficiently reversed by vitamin E administration. It has been found that CAPE, but not NAC has protective effects on Dox-induced hepatocellular damage. Human & Experimental Toxicology (2007) 26, 519—525

Experimental evidence from previous study has demonstrated the hypolipidemic effects of Oryctes rhinoceros oil (ORO) when fed as a supplement to a cholesterol-based diet. Due to renew interest in the consumption of insect derived oil, the present study was designed to elucidate the effect of Oryctes rhinoceros oil (ORO) supplementation in comparison to vitamin E on oxidative status in some tissues of rats fed a cholesterol-based diet. Forty (40) Swiss albino rats were divided into 4 groups (n = 10) and maintained on a basal diet (cholesterol free as control), a cholesterol-based diet (5% cholesterol as cholesterol), a cholesterol-based diet supplemented with ORO (cholesterol + ORO) and a cholesterol-based diet supplemented with vitamin E (Cholesterol + vit E) for 10 weeks. Animals in the cholesterol group had a significantly (p <0.05) higher malondialdehyde (MDA), conjugated diene and nitric oxide concentrations in the serum, liver, heart, kidney and lung compared to control, cholesterol + ORO and cholesterol + vit E groups. Tissue glutathione (GSH) concentration was significantly (p <0.05) higher in rats fed cholesterol-based diet supplemented with ORO and vitamin E compared to those fed cholesterol-based diet alone. Xanthine oxidase activity was significantly (p <0.05) reduced in tissues of rats fed ORO and vitamin E supplemented diets compared to cholesterol rat group. In addition, catalase and superoxide dismutase activities in the various tissues examined were significantly (p <0.05) higher in both ORO and vitamin E supplemented groups compared to the cholesterol group. No significant difference was observed between animals fed ORO and vitamin E supplemented diets. These results showed that Oryctes rhinoceros larva oil exhibited similar protective effects to vitamin E against diet-induced oxidative stress in rats. In addition, data from this study showed that Oryctes rhinoceros larva oil possessed antioxidant property. Overall, the potential nutritional benefit of Oryctes rhincoceros larva oil consumption on cardiovascular health could possibly involve its ability to upregulation of cellular antioxidant defense mechanisms.
