Abstract
The target of this study was to evaluate the effect of extract of the European mistletoe - Viscum album quercus L. on spermatozoa motility and viability in vitro. The CASA system was used to determine the spermatozoa motility parameters at different time intervals (0, 1, 2 and 3 h) and spermatozoa viability was determined in five different doses of Viscum album quercus L [10 (QA), 6.6 (QB), 3.3 (QC), 2.5 (QD) and 2 (QE) mg/ml]. Results in experimental groups detected a significant deterioration on rabbit spermatozoa after 1, 2 and 3 hours, compared to the control. The initial total spermatozoa motility showed increased value for all doses of Viscum album quercus in comparison to control. After in vitro culture a dose-dependent decrease (QA: reduction of 69.7 %, QB: reduction of 40.9 %) was found. For the progressive spermatozoa most significant decrease (86.8 % for QA vs. 48.5 % for QB) was detected compared to the control after 3 hours of culture. Spermatozoa viability (MTT test) was decreased in all experiment groups at the end of experiment, but the differences were not significant. Significant alterations of membrane integrity were found in groups with the highest Viscum album quercus concentration (QA, QB), but acrosome integrity showed no significant changes. Results suggest negative dose- and time-dependent effect of Viscum album quercus at higher doses on spermatozoa motility and viability parameters in vitro.

Elblehi SS, El Euony OI, El-Nahas AF. Partial ameliorative effect of Moringa leaf ethanolic extract on the reproductive toxicity and the expression of steroidogenic genes induced by subchronic cadmium in male rats. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2019; 26:23306-23318.

Abstract
The impact of Moringa oleifera leaf ethanol extract (MOLEE) was assessed on the expression of the steroidogenic genes (steroidogenic acute regulatory protein (StAR) and cytochrome P450c17 subfamily a (CYP17a) and luteinizing hormone receptor (LHR) gene) as well as on the cadmium chloride (CdCl2)-induced reproductive toxicity for 56 days in male rats. Four groups were used: control, Moringa-treated (MOLEE), CdCl2-treated, and CdCl2 + MOLEE groups. The reproductive toxicity of CdCl2 was confirmed; it caused a significant decrease in the accessory sex organ weights, testosterone level, testicular GST level, elevated MDA level (lipid peroxidation indicator), and histopathological alterations in seminiferous tubules, prostate, seminal vesicles, and epididymis as well as sperm characteristics. It also induced downregulation in the expression of StAR and CYP17a genes without change in the expression LHR gene. Eleven active compounds were detected in the GC-MS analysis of MOLEE; six of them have antioxidant properties, and five new compounds presented variable activities. MOLEE alone induced a stimulatory effect on the expression of steroidogenic and LHR genes. It restored the weight of reproductive organs to the control level; however, the recovery in sperm count, motility, abnormalities, percentage of alive sperm, testosterone, and MDA level are still comparable with the control level. Similar findings were also reported at the histological structure of the testes, epididymis, and accessory sex glands. Complete recovery of the GST enzyme activity was observed. Additionally, a restoration in the expression level of the steroidogenic genes was also reported. Our results indicated that the concurrent administration of MOLEE with CdCl2 can partially mitigate its harmful effects on male fertility.

Abstract
Early-life chronic exposure to environmental contaminants, such as bisphenol-A, particulate matter air pollution, organophosphorus pesticides, and pharmaceutical drugs, among others, may affect central tissues, such as the hypothalamus, and peripheral tissues, such as the endocrine pancreas, causing inflammation and apoptosis with severe implications to the metabolism. The Developmental Origins of Health and Disease (DOHaD) concept articulates events in developmental phases of life, such as intrauterine, lactation, and adolescence, to later-life metabolism and health. These developmental phases are more susceptible to environmental changes, such as those caused by environmental contaminants, which may predispose individuals to obesity, metabolic syndrome, and chronic noncommunicable diseases later in life. Alterations in the epigenome are explored as an underlying mechanism to the programming effects on metabolism, as the expression of key genes related with central and peripheral metabolic functions may be altered in response to environmental disturbances. Studies show that environmental contaminants may affect gene expressions in mammals, especially when exposed to during the developmental phases of life, leading to metabolic disorders in adulthood. In this review, we discuss the current obesity epidemics, the DOHaD concept, pollutants' toxicology, environmental control, and the role of environmental contaminants in the central and peripheral programming of obesity and metabolic syndrome. Improving environmental monitoring may directly affect the quality of life of the population and help protect the future generations from metabolic diseases.

Abstract
This study aimed at investigating the protective role of CoQ10 against cadmium (Cd)-induced reproductive toxicity in male rats. Adult male Wistar rats were exposed to an acute dose of Cd (25 mg/kg bwt; Cd group), Cd+CoQ10 (25 mg/kg bwt Cd+10 mg CoQ10; Cd-Q10 group) and distilled water (control) in vivo for 15 consecutive days and semen quality was assessed. A significant reduction was noted in sperm concentration, progressive motility, morphology and DNA integrity in both Cd- and Cd-Q10 groups in comparison to control indicating Cd-induced testicular lipid per oxidation (LPO) and decline in indigenous antioxidant defense system as measured by total antioxidant capacity (TAC) (p<0.05). However, simultaneous co-administration of CoQ10 along with Cd (Cd-Q10 group) was able to improve sperm concentration, motility, progressive motility, morphology, DNA integrity, and testicular TAC as well as lower LPO compared to Cd group (p<0.05). Results indicate that used dose of CoQ10 is capable of moderately ameliorating reproductive toxicity of Cd by improving semen quality and reducing testicular oxidative stress.

Abstract
This study was designed to evaluate protective effect of Saussurea lappa root aqueous extract against Ethephon (2-chloroethylphosphonic acid)-induced reproductive toxicity in rats. Control group received distilled water. Second group was given S. lappa extract at a dose 50 mg/kg bw. Third group was given Ethephon at a dose 200 mg/kg bw. Fourth, fifth, and sixth groups were given S. lappa extract before, with or after Ethephon administration, respectively. Ethephon intoxication significantly decreased serum levels of follicle stimulating hormone, luteinizing hormone, testosterone, and prolactin. Also, it significantly decreased sperms count, vitality, morphology index, total motility, progressive motility, and proliferating cell nuclear antigen protein expressions in spermatogonia. However, it significantly increased sperms abnormalities, testicular tissue and DNA damages, P53 protein expressions, noprogressive motility, and immotile sperms. In contrast, S. lappa extract ameliorated these alterations. These results indicated that S. lappa had potential preventive and curative effects against Ethephon-induced reproductive toxicity in rats.

Abstract
Cadmium (Cd) is harmful for humans and animals, especially for the reproductive system. However, the mechanism of its toxicity has not been elucidated, and how to alleviate its toxicity is very important. This study aimed to explore the role and mechanism of action of sulforaphane (SFN) in protecting mouse Leydigs (TM3) cells from cadmium (Cd)-induced damage. The half-maximal inhibitory concentration (IC50) of Cd and the safe doses of SFN were determined using a methyl thiazolyl tetrazolium (MTT) assay. The testosterone secretion from TM3 cells was measured using the enzyme-linked immunosorbent assay. The intracellular oxidative stress was evaluated using corresponding kits. The cell apoptosis was detected using flow cytometry. The mRNA expression of genes associated with NF-E2-related factor 2 (Nrf2)/antioxidant response element (ARE) signaling was detected using reverse transcription–polymerase chain reaction, including Nrf2, heme oxygenase I (HO-1), glutathione peroxidase (GSH-Px), NAD(P)H:quinone acceptor oxidoreductase 1 (NQO1), and γ-glutamylcysteine synthetase (γ-GCS). The protein expression of Nrf2, GSH-Px, HO-1, γ-GCS, and NQO1 was detected using Western blot analysis. The results showed that the IC50 of Cd to TM3 cells was 51.4 µmol/L. SFN reduced the release of lactate dehydrogenase from Cd-exposed cells. Cd + SFN 2.5 treatment significantly elevated testosterone concentration compared with the Cd group (p < 0.05). SFN significantly increased total superoxide dismutase (T-SOD) and GSH-Px activity and GSH content in Cd-treated cells (p < 0.05; p < 0.01), inhibited the production of malondialdehyde or reactive oxygen species caused by Cd (p < 0.05; p < 0.01), and reduced the apoptotic rate of Cd-induced TM3 cells (p < 0.01). SFN upregulated the mRNA expression of Nrf2, GSH-Px, HO-1, NQO1, and γ-GCS in Cd-treated cells, indicating the protective effect of SFN against Cd-induced oxidative stress or cell apoptosis by activating the Nrf2/ARE signaling pathway.

Abstract
INTRODUCTION Organophosphate compounds (OPCs) are suspected to make changes in reproductive function by oxidant/antioxidant balance disruption in the brain, consequently impairing hypothalamic, pituitary endocrine functions, and gonadal processes. The aim of this study was to investigate the effects of occupational exposure to OPCs on the reproductive system of farm workers, in Hamadan, Iran. MATERIALS AND METHODS A comparative study was conducted in rural farmers and urban men aged 20-40 years. After sampling and analysis of semen quality parameters (such as sperm count, sperm motility, progressive sperm motility, and sperm morphology), serum butyrylcholinesterase (BChE) activity (a specific biomarker in OPCs exposure), as well as total antioxidant capacity, nitric oxide, and lipid peroxidation levels for both semen and serum samples were determined. In addition, serum samples were analyzed for reproductive hormones, including follicle-stimulating hormone, luteinizing hormone (LH), and testosterone. RESULTS Our findings showed that the number of sperms (P = 0.04), their motility (P < 0.001), and progressive status (P < 0.001) in rural farmers were significantly lower than the urban population. In addition, a significant decrease was observed in BChE activity (P < 0.001) and LH level (P < 0.001), and also a remarkable increase was found in testosterone level (P = 0.0014) in the serum of rural farmers compared to the urban population. Along with a decrease in semen total antioxidant capacity, a positive significant correlation was found between sperm motility and semen antioxidant capacity (r = 0.45; P < 0.05). CONCLUSION Exposure to OPCs may affect reproductive outcomes through impairing hypothalamic and/or pituitary endocrine dysfunctions and gonadal processes in farmers.

Abstract
Brominated flame retardants (BFRs) and heavy metals (HMs) are two main types of pollutants in electronic waste recycling sites, which are also ubiquitously detectable in environmental media and human tissues. However, the adverse health effects of exposure to the mixture of these types of pollutants are unknown. In this study, we investigated the reproductive toxicity of a mixture of decabromodiphenyl ether (BDE-209), tetrabromobisphenol A, cadmium chloride, and lead acetate (PbAc) at the environmental relevant levels. Zebrafish were waterborne and exposed to chemical mixtures for one generation. The reproductive effects were evaluated for F0 adults and F1 offspring. Chemical residues were also analyzed in the exposed adults and their eggs at the end of exposure. Our findings demonstrated that exposure to the chemical mixture for 150 days had no effect on the survival rate of zebrafish, but it decreased body length and weight in females and increased body weight and condition factor in males. The mixture exposure resulted in a female-biased sex ratio in adults and decreased sperm density and motility in males and egg production in females. For the F1 offspring, decreased fertilization, delayed hatching, and increased malformation were found in all exposure groups. In conclusion, chronic co-exposure to BFRs and HMs at the environmental relevant levels not only affected growth, sex ratio, and sperm quantity/quality and egg production in adults but also reduced the reproductive success in the offspring, implying that multi-pollutants in the environmental media may pose a public health risk to other exposed organisms or human beings.

Abstract
The purpose of this study was to evaluate the potential chemoprotective effects of proanthocyanidins (PAs) against cadmium (Cd)-induced oxidative damage of testes via Nrf2-Keap1 signal pathway in rats. Briefly, by using biochemical histological analysis, as well as the real time PCR and western blot approach, oxidative damage in rat testicular tissue was observed after exposure to Cd. In addition, significant down-regulations of mRNA and protein levels of nuclear erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1), γ-glutamyl cysteine synthetase (γ-GCS), glutathione peroxidase (GSH-Px) and quinone oxidoreductase 1 (NQO1), as well as a significant up-regulation of Kelch sample related protein-1 (Keap1) levels in testicular tissue were observed after Cd exposure. Notably, these alterations were reverted back to near normalcy in Cd+PAs group rats. In conclusion, PAs exhibited a significant chemopreventive potential against Cd-induced testicular oxidative damage in rats, possibly through the modification of Nrf2-Keap1 signal path.

Abstract
The concentrations of selenium (Se), cadmium (Cd) and diazinon (DZN) in selected tissues of rats after an oral administration in various combinations were analyzed. Male rats were orally dosed with diazinon (40 mg.L-1), diazinon (40 mg.L-1) +selenium (5 mg.L-1), diazinon (40 mg.L-1) +cadmium (30 mg.L-1), and diazinon (40 mg.L-1) +selenium (5 mg.L-1) +cadmium (30 mg.L-1) in drinking water. After 90 days of per oral administration of compounds, the samples of liver, kidney, muscle tissue (m. quadriceps femoris), and adipose tissue were collected. The content of DZN was analyzed using Gas Chromatography - Mass Spectrometry (GC-MS), Cd was analyzed using an Electrothermal Atomic Absorption Spectrometry (ETAAS) and Se using a Hydride Generation Atomic Absorption Spectrometry (HG-AAS) methods. Cadmium significantly increased in liver and kidney after DZN +Cd and DZN +Se +Cd administration. Se significantly increased in liver of DZN +Se, DZN +Se +Cd and DZN +Cd exposed rats, in kidney of DZN +Se and DZN +Se +Cd and DZN +Cd, and in muscle of DZN +Se +Cd group. Highest DZN content was found in the adipose tissue in DZN, DZN +Cd and DZN +Se +Cd but not in combined exposure with Se. Anyway, the differences between the control and experimental groups were not significant. The results indicate that cadmium and selenium accumulate mainly in liver, kidney and selenium also in muscle after p.o. administration but diazinon concentrations increases were not signifcant. The co-administration of diazinon, Se and Cd affects the content of these compounds in the organism and the accumulation rate depends on the combination of administered compounds. Diazinon and cadmium could contribute to the selenium redistribution in the organism after the peroral intake.

Cadmium is a major environmental toxicant that is released into the atmosphere, water and soil in the form of cadmium oxide, cadmium chloride, or cadmium sulfide via industrial activities, such as the manufacturing of batteries and pigments, metal smelting and refining and municipal waste incineration. In the present study, we investigated the effects of cadmium exposure on sperm quality parameters, fertilization capacity and early embryonic development. Our study showed that in vitro incubation of human or mouse sperms with cadmium for a long time (up to 24 hours) could significantly decreased sperm motility in a concentration- and time-dependent manner. Exposure to cadmium in the environment for a short term (30 min) did not affect sperm motility but significantly reduced in vitro fertilization rate. We also evaluated the effects of cadmium at concentrations of 0.625 μg/ml, and 1.25 μg/ml on early embryonic development in vitro and observed that the blastocyst formation rate dramatically decreased with increasing cadmium concentration. This finding emphasizes the hazardous effects of cadmium on sperm quality as well as on natural embryo development and raises greater concerns regarding cadmium pollution.
