Abstract
Zinc plays a very important role in various biological activities of the body. Multifaceted role of zinc is also known in testes development, spermatogenesis, capacitation and has effect on spermatozoa motility. On the other hand, the growing industry of nanotechnology has created reasonable interest of the risk assessment for nanoparticles. The aim of this study was to evaluate in vitro effect of zinc oxide (ZnO) nanoparticles on rabbit spermatozoa. Fresh semen was collected from sexually mature New Zealand rabbits. Experimental groups were prepared by diluting semen with ZnO nanoparticles in seven different concentrations (6-391 mg/mL). The experimental groups were compared with control group. Semen was assessed using computer assisted semen analysis (CASA) at intervals of 0, 1, 2 and 3 h of incubation. The mitochondrial toxicity assay (MTT) assay was used to determine cell viability. The results of monitored motility parameters in experimental groups showed a decreasing trend during whole experiment. Significant decrease (P < 0.001) of motility and progressive motility was observed after 3 h of incubation in samples cultured with higher ZnO nanoparticles in comparison to the control group. After 3 h of incubation, viability of rabbit spermatozoa showed slightly increased values in group with the lowest concentration of ZnO nanoparticles, but in other groups viability showed non-significant decrease compared to control. Similar tendency was detected for spermatozoa membrane integrity. These original data show the negative dose-dependent effect of ZnO nanoparticles on spermatozoa motility and viability parameters.

Abstract
Sclerosing agents as zinc gluconate-based chemical sterilants (Infertile®) are used for chemical castration. This solution is injected into the animal testis, but there are not enough evidences of its safety profiles for the receivers. The present work aimed to establish the pharmacokinetics and toxicological activity of Infertile, using in vitro and in silico approaches. The evaluation at the endpoint showed effects in a dose-dependent manner. Since necrosis is potentially carcinogenic, the possible cell death mechanism could be apoptosis. Our data suggested that Infertile at 60 mM presented risk for animal health. Even though Infertile is a licensed product by the Brazilian Ministry of Agriculture, Livestock and Supply, it presented a high mutagenic potential. We suggest that the optimal dose must be less than 6 mM, once, at this concentration, no mutagenicity or genotoxicity was observed.

Abstract
Zinc (Zn) is one of the most important trace elements required for several biological processes. Diabetes negatively affects many organs, and diabetic patients are often hypozincemic. The present study aims to investigate the role of Zn supplementation in the testes, epididymis, and sperms of streptozotocin (STZ)-induced diabetic rat. Serum, testicular, and sperm Zn contents were found to be altered in diabetic rat. Biochemical, histopathological, and protein expression profiles were determined to decipher the role of Zn in protecting the cellular perturbations. Further, histopathological analyses of testes and epididymis showed deranged architecture along with other noted abnormalities. Diabetic testes showed decreased Nrf2, HO-1, SOD1, PCNA, and Bcl-2 expressions whereas increased COX-2, NF-κB, MT, IL-6, and p-ERK levels. SOD1 and GPX5 were decreased in the epididymis of diabetic rat, whereas Zn supplementation attenuated these changes. The present results demonstrate the beneficial role of Zn supplementation in diabetes-associated testicular alterations of rat.

Abstract
BACKGROUND Older men tend to have poorer semen quality and are generally at higher risks for infertility and abnormal reproductive outcomes. METHODS We employed proton-induced X-ray emission (PIXE, 3 MeV proton beam) to investigate the concentrations of zinc, copper, calcium, sulfur, chlorine, potassium, titanium, iron and nickel in washed sperm and seminal plasma from non-smoking groups of 10 older men (65-80 years old) and 10 younger men (22-28 years old) who were concurrently assayed for sperm function and genomicly defective sperm. RESULTS The older group showed elevated zinc, copper and calcium in sperm and elevated sulfur in seminal plasma compared with the younger men. The older group also showed reduced motility as well as increased sperm DNA fragmentation, achondroplasia mutations, DNA strand breaks and chromosomal aberrations. Sperm calcium and copper were positively associated with sperm DNA fragmentation (P < 0.03). Seminal sulfur was positively associated with sperm DNA fragmentation and chromosomal aberrations (P < 0.04), and negatively associated with sperm motility (P < 0.05). Sperm calcium was negatively associated with sperm motility, independent of male age (P = 0.01). CONCLUSIONS We identified major differences in elemental concentrations between sperm and seminal plasma and that higher sperm copper, sulfur and calcium are quantitatively associated with poorer semen quality and increased frequencies of genomic sperm defects.

Micronutrients intake is associated with improved sperm DNA quality in older men. Fertil Steril 2012; 98:1130-7.e1.

Abstract
OBJECTIVE To investigate whether lifestyle factors such as increased dietary intake of micronutrients reduce the risks of sperm DNA damage, and whether older men benefit more than younger men. DESIGN Cross-sectional study design with equalized assignments into age groups. SETTING National laboratory and university. PATIENT(S) Nonclinical group of 22-80-year-old nonsmoking men (n = 80) who reported no fertility problems. MAIN OUTCOME MEASURE(S) Sperm DNA damage measured by alkaline and neutral DNA electrophoresis (i.e., sperm Comet assay). RESULT(S) Sociodemographics, occupational exposures, medical and reproductive histories, and lifestyle habits were determined by questionnaire. The average daily dietary and supplement intake of micronutrients (vitamin C, vitamin E, b-carotene, zinc, and folate) was determined using the 100-item Modified Block Food Frequency Questionnaire (FFQ). Men with the highest intake of vitamin C had approximately 16% less sperm DNA damage (alkaline sperm Comet) than men with the lowest intake, with similar findings for vitamin E, folate, and zinc (but not β-carotene). Older men (>44 years) with the highest vitamin C intake had approximately 20% less sperm DNA damage compared with older men with the lowest intake, with similar findings for vitamin E and zinc. The older men with the highest intake of these micronutrients showed levels of sperm damage that were similar to those of the younger men. However, younger men (<44 years) did not benefit from higher intakes of the micronutrients surveyed. CONCLUSION(S) Men with higher dietary and supplement intake of certain micronutrients may produce sperm with less DNA damage, especially among older men. This raises the broader question of how lifestyle factors, including higher intakes of antioxidants and micronutrients, might protect somatic as well as germ cells against age-associated genomic damage.

Abstract
The aim of the present study was to evaluate the effects of zinc on fertility through semen parameters, testosterone level and oxidative DNA damage to spermatozoa of rats exposed to cigarette smoke. Male Wistar rats (60 days old) were divided into four groups (n = 10 per group): control, cigarette-smoking (20 cigarettes per day), zinc (zinc chloride 20 mg kg–1 day–1) and zinc plus cigarette-smoking (zinc chloride 20 mg kg–1 day–1; 20 cigarettes per day). The treatment was applied for nine weeks and the following parameters were analysed: bodyweight, wet weights of the reproductive organs and the adrenal gland, plasma testosterone concentration, testicular function (seminal analysis and daily sperm production) and sperm DNA oxidative damage. The exposure to cigarette smoke decreased testosterone concentration, the percentage of normal morphology and the motility of spermatozoa. In addition, this exposure increased sperm DNA oxidative damage. Zinc treatment protected against the toxic damage that smoking caused to spermatozoa. This study showed a correlation between smoking and possible male infertility and subfertility, and also that the majority of smoking-induced changes in spermatozoa were prevented by zinc treatment. In conclusion, zinc, an antioxidant and stimulant of cell division, can be indicated as a promising treatment in men with infertility caused by the toxic components of cigarette smoke.

Abstract
Inbreeding is known to cause deleterious effects upon reproduction and survival, but its effects upon sperm DNA integrity have not been examined. In the present study, we analyzed this relationship among three endangered ungulates: Gazella cuvieri, Gazella dama mhorr, and Gazella dorcas neglecta. In addition, we examined whether levels of sperm DNA fragmentation are associated with semen quality. The magnitude of sperm DNA damage in the two species with high levels of inbreeding (G. cuvieri and G. dama mhorr) was extremely high when compared to the species with low levels of inbreeding (G. dorcas neglecta) and to values previously reported for outbred populations. Levels of sperm DNA fragmentation significantly increased with inbreeding and age. Increased DNA damage in sperm was associated with increased sperm head abnormalities, lower percentage of sperm with an intact acrosome, and poor motility. Our findings suggest that the link between inbreeding and semen quality is mediated by the effects of inbreeding upon sperm DNA damage. The deleterious effects of inbreeding upon the paternal genome likely decrease male fertility and may cause genetic damage to future generations. Because inbreeding is common among endangered species, high levels of sperm DNA damage may have considerable impact upon the viability of their populations.

Abstract
Oxidative stress is now recognized as a common pathology that affects up to half of all infertile men. One of the principal mechanisms by which oxidative stress produces infertility is by damage to sperm DNA, either through direct oxidation of the DNA by reactive oxygen species (ROS) or by the initiation of apoptosis. The objective of this study was to determine if an oral antioxidant/mineral supplement could improve sperm DNA integrity in men with known oxidative stress. A total of 50 infertile men identified as exhibiting oxidative stress were administered oral antioxidant therapy for a period of 3 months. All participants were assessed at entry and exit for sperm DNA integrity with terminal deoxynucleotidyl transferase-mediated dUDP nick-end labelling, apoptosis with annexin V, protamination with chromomycin A(3) and ROS production with nitro blue tetrazolium assay. Sperm concentration, motility and morphology, together with assessment of serum male reproductive hormones (LH, FSH, testosterone, anti-Mullerian hormone), were also monitored. The principal finding that emerged from this study was that antioxidant therapy resulted in significant improvements in sperm DNA integrity (P = 0.002) and protamine packaging (P < 0.001), accompanied by a reduction in seminal ROS production (P = 0.027) and apoptosis (P = 0.004). No significant changes in routine sperm parameters (concentration, motility, morphology) or male reproductive hormones were observed.

Abstract
In studies of environmental effects on human health outcomes, it is often difficult to assess the effects of a group of exposure variables when the individual exposures do not appear to have statistically significant effects. To address this situation, we propose a method of U-scores applied to subsets of multivariate data. We illustrate the usefulness of this approach by applying it to data collected as part of a study on the effects of metal exposure on human semen parameters. In this analysis, profiles (pairs) of metals containing copper and/or manganese were negatively correlated with total motile sperm and profiles containing copper were negatively correlated with sperm morphology; profiles containing selenium and chromium were positively correlated with total motile sperm.

Abstract
BACKGROUND Evidence on human semen quality as it relates to exposure to various metals, both essential (e.g., zinc, copper) and nonessential (e.g., cadmium, lead), is inconsistent. Most studies to date used small sample sizes and were unable to account for important covariates. OBJECTIVES Our goal in this study was to assess relationships between exposure to multiple metals at environmental levels and human semen-quality parameters. METHODS We measured semen quality and metals in blood (arsenic, Cd, chromium, Cu, Pb, manganese, mercury, molybdenum, selenium, and Zn) among 219 men recruited through two infertility clinics. We used multiple statistical approaches to assess relationships between metals and semen quality while accounting for important covariates and various metals. RESULTS Among a number of notable findings, the associations involving Mo were the most consistent over the various statistical approaches. We found dose-dependent trends between Mo and declined sperm concentration and normal morphology, even when considering potential confounders and other metals. For example, adjusted odds ratios (ORs) for below-reference semen-quality parameters in the low, medium, and high Mo groups were 1.0 (reference), 1.4 [95% confidence interval (CI), 0.5-3.7], and 3.5 (95% CI, 1.1-11) for sperm concentration and 1.0 (reference), 0.8 (95% CI, 0.3-1.9), and 2.6 (95% CI, 1.0-7.0) for morphology. We also found preliminary evidence for interactions between Mo and low Cu or Zn. In stratified analyses, the adjusted ORs in the high Mo/low Cu group were 14.4 (1.6, 132) and 13.7 (1.6, 114) for below-reference sperm concentration and morphology, respectively. CONCLUSIONS Our findings represent the first human evidence for an inverse association between Mo and semen quality. These relationships are consistent with animal data, but additional human and mechanistic studies are needed.

Abstract
BACKGROUND Little is known about the effect of paternal nutrition on aneuploidy in sperm. We investigated the association of normal dietary and supplement intake of folate, zinc and antioxidants (vitamin C, vitamin E and beta-carotene) with the frequency of aneuploidy in human sperm. METHODS Sperm samples from 89 healthy, non-smoking men from a non-clinical setting were analysed for aneuploidy using fluorescent in situ hybridization with probes for chromosomes X, Y and 21. Daily total intake (diet and supplements) for zinc, folate, vitamin C, vitamin E and beta-carotene was derived from a food frequency questionnaire. Potential confounders were obtained from a self-administered questionnaire. RESULTS After adjusting for covariates, men with high folate intake (>75th percentile) had lower frequencies of sperm with disomies X, 21, sex nullisomy, and a lower aggregate measure of sperm aneuploidy (P <or= 0.04) compared with men with lower intake. In adjusted continuous analyses, total folate intake was inversely associated with aggregate sperm aneuploidy (-3.6% change/100 microg folate; 95% CI: -6.3, -0. 8) and results were similar for disomies X, 21 and sex nullisomy. No consistent associations were found between antioxidant or zinc intakes and sperm aneuploidy. CONCLUSIONS Men with high folate intake had lower overall frequencies of several types of aneuploid sperm.

Abstract
A two-generation reproductive toxicity study of zinc chloride (ZnCl(2)) was conducted in rats. F(o) male and female rats were administered 0.00 (control), 7.50 (low), 15.00 (mid) and 30.00 (high) mg/kg/day of ZnCl(2). Selected F(1) male and female rats were exposed to the same doses received by their parents (F(o)). Exposure of F(0) parental rats to ZnCl(2) showed significant reduction in fertility, viability (days 0 and 4), and the body weight of F(1) pups from the high-dose group but caused no effects on litter size, weaning index, and sex ratio. Similarly, the continued exposure of F(1) parental rats to ZnCl(2) also reduced fertility, liter size, viability (day 0), and the body weight of F(2) pups within the high-dose group but caused no effects on weaning index and sex ratio. Exposure of ZnCl(2) to F(0) and F(1) parental males resulted in a significant reduction in their body weights, and the F(0) and F(1) parental females did not show any significant difference in their body weights compared to their control groups. However, the postpartum dam weights of both F(0) and F(1) female rats were significantly reduced compared to their controls. Exposure of ZnCl(2) to F(o) and F(1) generation parental rats did not produce any significant change of their clinical signs as well as their clinical pathology parameters, except the alkaline phosphotase (ALK) level, which showed an upward trend in both sexes of both generations. Exposure of ZnCl(2) to F(0) rats resulted in a reduction of brain, liver, kidney, spleen and seminal vesicles weights of males and in the spleen and uterus of females. Similarly, exposure of F(1) rats to ZnCl(2) also resulted in reduction of brain, liver, kidney, adrenal, spleen, prostate and seminal vesicles weights of males and in spleen and uterus of females. ZnCl(2) exposure resulted in grossly observed gastro-intestianla (GI) tract, lymphoreticular/hematopoietic, and reproductive tract lesions in parental rats in both generations. Reduced body fat was also recorded in F(1) parental rats.

Abstract
We present (29)Si, (27)Al, and (67)Zn NMR evidence to show that silicate ions in alkaline solution form complexes with zinc(II) (present as zincate, Zn(OH)(3)(-) or Zn(OH)(4)(2-)) and, concomitantly, with aluminate (Al(OH)(4)(-)). Zincate reacts with monomeric silicate at pH 14-15 to form [(HO)O(2)Si-O-Zn(OH)(3)](4-) and with dimeric silicate to produce [HO-SiO(2)-O-SiO(2)-O-Zn(OH)(3)](6-). The exchange of Si between these free and Zn-bound sites is immeasurably fast on the (29)Si NMR time scale. The cyclic silicate trimer reacts relatively slowly and incompletely with zincate to form [(HO)(3)Zn{(SiO(3))(3)}](7-). The concentration of the cyclic trimer becomes further depleted because zincate scavenges the silicate monomer and dimer, with which the cyclic trimer is in equilibrium on the time scale of sample preparation. Identification of these zincate-silicate complexes is supported by quantum chemical theoretical calculations. Aluminate and zincate, when present together, compete roughly equally for a deficiency of silicate to form [(HO)(3)ZnOSiO(2)OH](4-) and [(HO)(3)AlOSiO(2)OH](3-) which exchange (29)Si at a fast but measurable rate.

Abstract
Most studies utilizing transgenic technology focus on the impact to traits of interest, rather than propagation of the transgene to offspring. In animals containing growth hormone constructs, transgene transmission to progeny follows a Mendelian pattern of inheritance in the first few generations following generation of a founder animal, but decreases in subsequent generations. In the present study, the ovine metallothionein 1a-ovine growth hormone (oMt1a-oGH) transgenic mouse was used to determine whether transgene transmission rate to progeny was affected by overexpression of ovine growth hormone in the transgenic parent. The oMt1a-oGH mouse is a useful model for assessing transgene transmission, as the construct is easily regulatable and transgene inactivation results in a return of plasma GH to basal levels. Male and female hemizygous oMt1a-oGH mice were assigned to 1 of 3 treatment groups: (1) mice never actively expressing the transgene, (2) mice actively expressing the transgene from 3 weeks of age, and (3) mice actively expressing the transgene from 3 to 11 (males) or 3 to 8 (females) weeks of age. Transgenic mice were mated to wild type animals and the resulting progeny were genotyped. Males never actively expressing the transgene passed on the transgene to progeny in a Mendelian fashion, while males actively expressing the transgene transmitted the transgene to a smaller than expected number of progeny. However, following inactivation of the oMt1a-oGH construct in transgenic males, subsequent offspring demonstrated Mendelian inheritance of the transgene. In contrast, females expressing the transgene from 3 to 8 weeks of age were able to pass on the oMt1a-oGH construct in a Mendelian fashion, but females from other treatment groups were not. In oMt1a-oGH males, reduced transgene transmission appears to be due to selection against transgenic gametes. In females, however, selection against the transgenic genotype likely occurs at the embryonic level.

Abstract
The health safety of transgenic soybeans (glyphosate-tolerant or Roundup Ready) was studied using the mammalian testis (mouse model) as a sensitive biomonitor of potential toxic effects. Pregnant mice were fed a transgenic soybean or a non-transgenic (conventional) diet through gestation and lactation. After weaning, the young male mice were maintained on the respective diets. At 8, 16, 26, 32, 63 and 87 days after birth, three male mice and an adult reference mouse were killed, the testes surgically removed, and the cell populations measured by flow cytometry. Multi-generational studies were conducted in the same manner. The results showed that the transgenic foodstuffs had no effect on macromolecular synthesis or cell growth and differentiation as evidenced by no differences in the percentages of testicular cell populations (haploid, diploid, and tetraploid) between the transgenic soybean-fed mice and those fed the conventional diet. Additionally, there were no differences in litter sizes and body weights of the two groups. It was concluded that the transgenic soybean diet had no negative effect on fetal, postnatal, pubertal or adult testicular development.

Abstract
Zinc stabilizes membranes and DNA and inhibits respiration in somatic cells. It is present in high concentrations in the male reproductive tract and may stabilize spermatozoa prior to fertilization. Herein, we evaluate N-(6-methoxy-8-quinolyl)-p-toluenesulfonamide (TSQ) for analysis of Zn2+ in phosphatidylcholine (PC) vesicles and living spermatozoa using spectrofluorometry and flow cytometry. TSQ:Zn fluorescence in decanol or PC vesicles was compared to that in aqueous buffer. Evaluation of cation specificity, kinetics of TSQ:Zn binding, quenching of TSQ by dithionite and Zn2+ chelation by D-penicillamine established that TSQ is more fluorescent in decanol or PC vesicles than in aqueous buffer, has a high affinity for lipid bilayers and is specific for Zn2+ compared to Mg2+ and Ca2+. Fluorescence measurement of vesicles with and without pretreatment with Zn2+ indicated that, in the absence of Zn2+, 90% of the residual TSQ fluorescence was destroyed by dithionite but > 50% was protected by the presence of Zn2+. When D-penicillamine was added the remaining fluorescence was quenched (T1/2 = 10 s) indicating that TSQ remains in/on the membrane. These results established that TSQ can be used to effectively evaluate Zn2+ in artificial membranes and sperm cells. Additional experiments will be necessary to explain the dynamics of TSQ:Zn:membrane interactions.

Abstract
The sperm chromatin structure assay (SCSA) measures the susceptibility of sperm nuclear DNA to acid-induced denaturation in situ, and was developed on two Ortho flow cytometers, an FC200 [Becton Dickinson Immunocytometry Systems (BDIS), Westwood, MA] and a Cytofluorograf 30 (BDIS), both having orthogonal axes of fluorochrome excitation, emission, and sample flow. Sperm cells are first treated with a pH 1.4 buffer to denature DNA in situ and then stained with the metachromatic dye acridine orange (AO). The metachromatic fluorescence measured reflects relative amounts of denatured (red fluorescence) and native (green fluorescence) DNA present per cell. The extent of DNA denaturation is quantified by the calculated parameter alpha t [alpha t = red/(red+green) fluorescence]. Alpha t variables important for correlations with fertility and toxicant-induced chromatin damage include mean (X alpha t), standard deviation (SD alpha t), and cells outside the main population (COMP alpha t). Mean green fluorescence intensity is an important measure for DNA content and/or degree of sperm chromatin condensation. This study showed that the SCSA can be successfully run on two epiillumination-type instruments, an Ortho ICP22A (BDIS, San Jose, CA) and Skatron Argus (Tranby, Norway), and two additional orthogonal axes instruments, a Becton Dickinson FACScan (BDIS) and a Coulter Elite (Coulter Corporation, Hialeah, FL). Epiillumination instruments produced a different fluorescence distribution than orthogonal instruments, but the resulting alpha t values showed strong conformity and interpretation of results was the same. SCSA values obtained on the Coulter Elite were most similar to the Cytofluorograf 30; the FACScan green fluorescence distribution was narrower and allowed resolution of cell doublets.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Male rats were treated with phorone at dosages previously shown to reduce glutathione in rodent reproductive tracts, followed by a single challenge with ethyl methanesulfonate, a known mutagenic and clastogenic agent. Epididymal sperm collected 8 and 15 days after exposure from phorone pretreated animals had a significantly greater alteration of sperm chromatin structure, defined as an increased susceptibility to DNA denaturation in situ, relative to sperm obtained from animals injected with saline alone or saline+EMS (50, 100, 150, or 200 mg/kg bw). These data support the hypothesis that ethyl methanesulfonate-induced alkylation of developing sperm chromatin protamines causes a significant stress on chromatin structure leading to increased DNA damage. This is the first report showing that glutathione depletion potentiates EMS-induced chromatin structural alterations that are likely related to dominant lethal mutations.
