PART A, ECOLOGICAL AND INTEGRATIVE PHYSIOLOGY 2024; 341:31-40. [PMID: 37861072 DOI: 10.1002/jez.2758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 09/23/2023] [Accepted: 09/28/2023] [Indexed: 10/21/2023]
Abstract
Cadmium is a male reproductive toxicant that interacts with a variety of pathogenetic mechanisms. However, the effect of cadmium on the regulatory mechanism of the steroidogenic pathway of Leydig cells during spermatogenesis is still ambiguous. Light microscopy, Western blot, immunohistochemistry, immunofluorescence, and quantitative polymerase chain reaction were performed to study the regulatory mechanism of the steroidogenic pathway of Leydig cells during spermatogenesis. The results indicated that in the control group, Leydig cells showed dynamic immunoreactivity and immunosignaling action with a strong positive significant secretion of 3β-hydroxysteroid hydrogenase (3β-HSD) in the interstitial compartment of the testis. Leydig cells showed a high active regulator mechanism of the steroidogenic pathway with increased the proteins and genes expression level of steroidogenic acute regulatory protein (STAR), cytochrome P450 cholesterol (CYP11A1), cytochrome P450 cholesterol (CYP17A1), 3β-hydroxysteroid hydrogenase (3β-HSD) 17β-hydroxysteroid hydrogenase (17β-HSD), and androgen receptor (AR) that maintained the healthy and vigorous progressive motile spermatozoa. However, on treatment with cadmium, Leydig cells were irregularly dispersed in the interstitial compartment of the testis. Leydig cells showed reduced immunoreactivity and immunosignaling of 3β-HSD protein. Meanwhile, cadmium impaired the regulatory mechanism of the steroidogenic process of the Leydig cells with reduced protein and gene expression levels of STAR, CYP11A1, CYP17A1, 3β-HSD, 17β-HSD, and AR in the testis. Additionally, treatment with cadmium impaired the serum LH, FSH, and testosterone levels in blood as compared to control. This study explores the hazardous effect of cadmium on the regulatory mechanism of the steroidogenic pathway of Leydig cells during spermatogenesis.

Abstract
Arsenic being a toxic metalloid ubiquitously persists in environment and causes several health complications including female reproductive anomalies. Epidemiological studies documented birth anomalies due to arsenic exposure. Augmented reactive oxygen species (ROS) generation and quenched antioxidant pool are foremost consequences of arsenic threat. On the contrary, Vitamin E (VE) and C (VC) are persuasive antioxidants and conventionally used in toxicity management. Present study was designed to explore the extent of efficacy of combined VE and VC (VEC) against Sodium arsenite (NaAsO2) mediated ovarian damage. Thirty-six female Wistar rats were randomly divided into three groups (Grs) and treated for consecutive 30 days; Gr I (control) was vehicle fed, Gr II (treated) was gavaged with NaAsO2 (3 mg/kg/day), Gr III (supplement) was provided with VE (400 mg/kg/day) & VC (200 mg/kg/day) along with NaAsO2. Marked histological alterations were evidenced by disorganization in oocyte, granulosa cells and zona pellucida layers in treated group. Considerable reduction of different growing follicles along with increased atretic follicles was noted in treated group. Altered activities ofΔ5 3β-Hydroxysteroid dehydrogenase and 17β-Hydroxysteroid dehydrogenase accompanied by reduced luteinizing hormone, follicle-stimulating hormone and estradiol levels were observed in treated animals. Irregular estrous cyclicity pattern was also observed due to NaAsO2 threat. Surplus ROS production affected ovarian antioxidant strata as evidenced by altered oxidative stress markers. Provoked oxidative strain further affects DNA status of ovary. However, supplementation with VEC caused notable restoration from such disparaging effects of NaAsO2 toxicities. Antioxidant and antiapoptotic attributes of those vitamins might be liable for such restoration.

Thangavelu SK, Mohan M, Ramachandran I, Jagadeesan A. Lactational polychlorinated biphenyls exposure induces epigenetic alterations in the Leydig cells of progeny rats. Andrologia 2021; 53:e14160.

Abstract
The present study was designed to establish the epigenetic mechanisms by which lactational exposure to PCBs affects the Leydig cell function in progeny rats. The lactating dams were oral gavaged with different doses of PCBs [1, 2 and 5 mg/kg or corn oil ] and Leydig cells were isolated from the testes of progeny rats at postnatal day (PND) 60. We assessed the expression of transcription factors regulating steroidogenic machinery and the promoter methylation of LHR and AR in the Leydig cells. Our results confirmed hypermethylation of SF-1, Sp1/3, LHR and AR genes. There was a significant reduction in the gene expression of SF-1 and Sp1. The mRNA expression of Sp3 was decreased. Interestingly, there was an increased gene expression levels of DNA methyltransferases (Dnmts) (Dnmt1, Dnmt3a/b and Dnmt3l) and unaltered histone deacetylase-1 (Hdac-1). Furthermore, increased percentage of 5-methylcytosine was observed in PCBs exposed Leydig cells. Taken together, our findings suggest that promoter hypermethylation of SF-1, Sp1/3, LHR and AR could have led to transcriptional repression of these genes in Leydig cells. In conclusion, our study demonstrates that lactational exposure to PCBs caused epigenetic changes in the Leydig cells which could have impaired the Leydig cell function in progeny (PND60) rats.

Testosterone synthesis in testicular Leydig cells after long-term exposure to a static electric field (SEF). Toxicology 2021; 458:152836.

Abstract
China's clean energy and resources are mainly located in the west and north while electric load center is concentrated in the middle and east. Thus, these resources and energy need to be converted into electrical energy in situ and transported to electric load center through ultra-high voltage direct current (UHVDC) transmissions. China has built 25,000 km UHVDC transmission lines of 800 kV and 1100 kV, near which the impact of electric field on health has attracted public attention. Previous studies showed that time-varying electromagnetic field exposure could disturb testosterone secretion. To study the effect of non-time-varying electric field caused by direct current transmission lines on testosterone synthesis, male ICR mice were continually (24 h/d) exposed to static electric field of 56.3 ± 1.4 kV/m. Results showed that on the 3rd day of exposure and on the 7th day after ceasing the exposure of 28 d, serum testosterone level and testicular oxidative stress indicators didn't change significantly. On the 28th day of exposure, serum testosterone levels, testicular glutathione peroxidase (GSH-Px) activity, the mRNA and protein levels of testicular StAR, PBR, CYP11A1 decreased significantly, and testicular malondialdehyde (MDA) content increased significantly. Meanwhile, electron-dense edges and vacuolation appeared in lipid droplets of Leydig cells. The gap between inner mitochondrial membrane (IMM) and outer mitochondrial membrane (OMM) enlarged, which would cause the swelling of mitochondria, the rupture and deficiency of mitochondrial membranes. Analysis showed that testicular oxidative stress could induce the damage of mitochondrial structure in Leydig cells, which would decrease the rate of cholesterol transport from cytoplasm to mitochondria. Since cholesterol is the necessary precursor of testosterone synthesis, testosterone synthesis was inhibited. The decrease of the mRNA and protein expression levels of StAR and PBR in testes could diminish the cholesterol transported from OMM to IMM. The decrease of the mRNA and protein expression levels of CYP11A1 could reduce the pregnenolone required in testosterone synthesis and inhibit testosterone synthesis consequently.

Abstract
The purpose of the present study was to investigate the protective potential of Feijoa fruit extract on cadmium chloride (CdCl2 )-induced testicular injury and pituitary-gonadal axis. Adult male Wistar rats were randomly divided into four groups: (a) control (normal saline, orally), (b) cadmium chloride (0.1 mg/kg, single dose, intraperitoneally), (c) Feijoa fruit extract (400 mg/kg, orally for 30 consecutive days) and (d) CdCl2 + Feijoa fruit extract. One day after receiving the last medicine, the LH, FSH, prolactin and testosterone concentration were assayed. Also, sperm parameters and tissue structure of the testis were evaluated. Administration of Feijoa fruit extract after CdCl2 injection in rats ameliorated sperm parameters such as sperm count, morphology, motility and sperm viability, increased levels of LH, FSH, prolactin and testosterone and improved testicular histology. According to the results of this study, it was shown that Feijoa can reduce the destructive side effects of CdCl2 on testicular tissue and sex hormones of the pituitary-gonadal pathway.

Abstract
Introduction Polychlorinated biphenyl (PCB) is considered one of the environmental pollutants. It is used as hydraulic coils in vacuum pumps, pesticides transformers, heat-exchange systems, capacitors and as additives in adhesive inks, paints, plastics, copying paper and sealants. Alpha lipoic acid (ALA) is an antioxidant substance normally present in mitochondria as a coenzyme. Aim of the Work To evaluate the protective effect of ALA on PCB induced testicular toxicity. Materials and Methods Twenty five adult male albino rats were used in this study. They were divided into four groups, a control group included 10 rats, group II rats received alpha lipoic acid 25mg/Kg /day orally for 30 days, group III rats received PCB 5mg /Kg/day orally for 30 days and group IV rats received both PCB and alpha lipoic acid at the same previous dose for 30 days. At the appropriate time, the specimens were taken and prepared for light and electron microscope study. Results LM examination revealed structural alterations in group III in the form of wide spaces between seminiferous tubules that contain homogeneous acidophilic substance, partial or complete detachment of the tubules from the basement membrane and total distorted irregular shaped tubules. Also dilated congested blood vessels were seen. EM examination of this group revealed Sertoli cells with cytoplasmic vacuolation and dilated rER. The basement membrane appeared as thick and irregular line under Sertoli and spermatogenic cells and it was interrupted in some points. Primary spermatocyte appeared shrunken while others revealed vacuoles in the cytoplasm and perinuclear dilatation. Leydig cells showed irregular vacuoles and swollen destroyed mitochondria. Amelioration of the previous histological changes could be detected in group IV. Conclusion It could be concluded that alpha-lipoic acid has a protective effect against PCB induced testicular toxicity.

Abstract
Polychlorinated biphenyls (PCBs) consist of a range of toxic substances which are directly proportional to carcinogenesis and tumor-promoting factors as well as having neurotoxic properties. Reactive oxygen species, which are produced from PCBs, alter blood–brain barrier (BBB) integrity, which is paralleled by cytoskeletal rearrangements and redistribution and disappearance of tight junction proteins (TJPs) like claudin-5 and occludin. Brain-derived neurotrophic factor (BDNF), plays an important role in the maintenance, survival of neurons and synaptic plasticity. It is predominant in the hippocampal areas vital to learning, memory and higher thinking. Quercetin, a flavonoid, had drawn attention to its neurodefensive property. The study is to assess the role of quercetin on serum PCB, estradiol and testosterone levels and mRNA expressions of estrogen receptor α and β, TJPs and BDNF signaling molecules on the hippocampus of PCBs-exposed rats. Rats were divided into 4 groups of 6 each. Group I rats were intraperitoneally (i.p.) administered corn oil (vehicle). Group II received quercetin 50 mg/kg/bwt (gavage). Group III received PCBs (Aroclor 1254) at 2 mg/kg bwt (i.p). Group IV received quercetin 50 mg/kg bwt (gavage) simultaneously with PCBs 2 mg/kg bwt (i.p.). The treatment was given daily for 30 days. The rats were euthanized 24 h after the experimental period. Blood was collected for quantification of serum PCBs estradiol and testosterone. The hippocampus was dissected and processed for PCR and Western blot; serum PCB was observed in PCB treated animals, simultaneously quercetin treated animals showed PCB metabolites. Serum testosterone and estradiol were decreased after PCB exposure. Quercetin supplementation brought back normal levels. mRNA expressions of estrogen α and β were decreased in the hippocampus of PCB treated rats. TJPS and BDNF signalling molecules were decreased in hippocampus of PCB treated rats. Quercetin supplementation retrieved all the parameters. Quercetin alone treated animals showed no alteration. Thus in PCB caused neurotoxicity, quercetin protects and prevents neuronal damage in the hippocampus.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2019; 2019:7693010. [PMID: 31485248 PMCID: PMC6710732 DOI: 10.1155/2019/7693010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/31/2018] [Revised: 04/15/2019] [Accepted: 07/14/2019] [Indexed: 01/17/2023]
Abstract
BACKGROUND In this study, the male fertility-enhancing activity of 100, 200, and 400 mg/kg/day of Hunteria umbellata water seed extract (HU) in Wistar rats was studied for 60 days. In doing this, effect of repeated doses of HU was studied on the weight gain pattern, gonadosomatic index (GSI), serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (TS), prolactin (PRL), and estradiol (ES)} as well as testicular antioxidant status of the treated rats as a way of elucidating the mechanism(s) of action of HU. METHOD Thirty-six (36) male Wistar rats were randomly divided into six groups (I-VI) of six rats per group. Group I rats were gavaged with 10 ml/kg/day of distilled water and served as an untreated control; Group II rats were gavaged with 0.3 mg/kg/day of clomiphene in distilled water; Groups III-V rats received 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day of HU, respectively, and Group VI rats received 20 mg/kg/day of Vitamin C all in distilled water. All treatments were for 60 days after which the treated rats were humanely sacrificed. Sera of blood samples were processed for the above stated hormonal profile. Similarly, testicular tissues obtained were processed for semen analysis and complete antioxidant profile of the HU-treated testicles by assaying for superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH), glutathione reductase (GSR), glutathione peroxidase (GSH-Px), and Thiobarbituric Reactive Species (TBARS). RESULTS Prolonged treatments with 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day of HU for 60 days induced dose dependent reductions in weight gain pattern with the most significant (p<0.001) effect recorded with the highest dose of HU. Conversely, significant (p<0.001) increase was recorded for GSI at the same HU dose. Clomiphene and HU also induced significant (p<0.01, p<0.001) dose dependent increases in the total sperm count, %live sperm, but reverse effects on %dead sperm and %abnormal sperm. On the hormonal profile, oral treatment with 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day of the extract induced profound (p<0.05, p<0.01, and p<0.001) dose related increases in the sera TS, LH, and FSH while it caused reverse effect on serum PRL but caused no significant alterations in the serum ES levels. Similarly, oral treatment with vitamin C and 100-400 mg/kg/day of HU induced profound (p<0.05, p<0.01, and p<0.001) increases in the antioxidant enzyme activities. CONCLUSION Overall, prolonged oral treatment with 100-400 mg/kg body weight of HU for 60 days significantly improved sperm function which was mediated via enhanced spermatogenesis, steroidogenesis, and antioxidant mechanisms.

Abstract
Endometriosis is an extremely heterogeneous disease and affects about ten percent of the female population during their reproductive years. Recent studies showed that endometriosis is an angiogenesis-dependent disease. Peritoneal macrophages are a well-characterised source of vascular endothelial growth factor (VEGF). The aim of this study was to determine the VEGF gene expression and production in peritoneal macrophages of patients with endometriosis under the effects of vitamins C and E in comparison with control. The lab trial study carried out on 50 patients undergoing laparoscopy and peritoneal fluid samples were collected from them. We compared the VEGF gene expression and production in peritoneal macrophages among groups by using real-time polymerase chain reaction and enzyme-linked immunosorbent assay methods, respectively. Our results showed that gene expressions influenced by vitamin C increased in different concentrations and incubation times, except for the incubation time after 48 h. In the case of vitamin E, this was evident with the exception of vitamin E 50 μM after 24 h and vitamin E 100 μM after 48 h. Our findings indicated that vitamin C and E in different concentrations and incubation times altered VEGF gene expression in the peritoneal macrophages but they had not affected on VEGF productions. Impact statement What is already known on this subject? Previous studies showed that antioxidants play a key role in the inhibition of oxidative stress-induced damages and the reduction of pelvic pain in patients with endometriosis. Vitamin E and vitamin C are the main components in neutralising free radicals. Also, antioxidant consumption such as vitamin C and vitamin E in women with endometriosis showed an inverse correlation between antioxidant intake and endometriosis pathology. What do the results of this study add? Vitamin C and E in different concentrations and times of incubation altered vascular endothelial growth factor gene expression and production in peritoneal macrophages. What are the implications of these findings for clinical practice and/or further research? Further studies are needed to determine the effects of C and E vitamins in different concentrations on vascular endothelial growth factor gene expression and production in peritoneal macrophages and the possible roles of these vitamins in treating endometriosis.

Abstract
The aim of this study was to assess whether fish in Kollevåg, a sheltered bay on the western coast of Norway, previously utilized as a waste disposal site, could be affected by environmental contaminants leaking from the waste. Farmed, juvenile Atlantic cod (Gadus morhua) were caged for six weeks at three different locations in Kollevåg bay and at one reference location. Sediments and cod samples (bile and liver) were analyzed for polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), brominated flame retardants (BFRs), per-and polyfluoroalkyl substances (PFASs) and polycyclic aromatic hydrocarbon (PAH) metabolites, revealing a contamination gradient at the four stations. Furthermore, hepatosomatic index (HSI) and Fulton's condition factor (CF) were significantly lower in cod caged closest to the disposal site. Levels and activities of biomarker proteins, such as vitellogenin (Vtg), metallothionein (Mt), and biotransformation and oxidative stress enzymes, including cytochrome P450 1a and 3a (Cyp1a, Cyp3a), glutathione s-transferase (Gst) and catalase (Cat), were quantified in blood plasma and liver tissue. Hepatic Cat and Gst activities were significantly reduced in cod caged at the innermost stations in Kollevåg, indicating modulation of oxidative stress responses. However, these results contrasted with reduced hepatic lipid peroxidation. Significant increases in transcript levels were observed for genes involved in lipid metabolism (fasn and acly) in cod liver, while transcript levels of ovarian steroidogenic enzyme genes such as p450scc, cyp19, 3β-hsd and 20β-hsd showed significant station-dependent increases. Cyp1a and Vtg protein levels were however not significantly altered in cod caged in Kollevåg. Plasma levels of estradiol (E2) and testosterone (T) were determined by enzyme immunoassay (EIA) and showed elevated E2 levels, but only at the innermost station. We conclude that the bay of Kollevåg did not fullfill adequate environmental condition based on environmental quality standards (EQSs) for chemicals in coastal waters. Following a six weeks caging period, environmental contaminants accumulated in cod tissues and effects were observed on biomarker responses, especially those involved in reproductive processes in cod ovary.

Spermatogenesis dysfunction induced by PM 2.5 from automobile exhaust via the ROS-mediated MAPK signaling pathway. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2019; 167:161-168. [PMID: 30326357 DOI: 10.1016/j.ecoenv.2018.09.118] [Citation(s) in RCA: 59] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 09/26/2018] [Accepted: 09/27/2018] [Indexed: 06/08/2023]
Abstract
Long-term exposure to particulate matter 2.5 (PM2.5) from automobile exhaust impairs spermatogenesis through oxidative stress injury, but the underlying mechanism is unknown. To investigate the toxic mechanism of PM2.5-induced spermatogenesis impairment, we focused on the MAPK signaling pathway. We also examined the effects of treatment with vitamins C and E on spermatogenic function. Male SD rats were divided randomly into three groups: control (0.9% sterilized saline), PM2.5 exposure (20 mg/kg.b.w.), and PM2.5 exposure (20 mg/kg.b.w.) with vitamin intervention (vitamin C, 100 mg/kg.b.w.; vitamin E, 50 mg/kg.b.w.). Male rats showed a marked decline in fertility and decreased sperm quality after PM2.5 exposure. The expression of SOD and Nrf2 was significantly decreased, and that of MDA was increased markedly. The expression of blood-testis barrier-associated proteins, such as ZO-1, occludin, connexin 43, and β-catenin, was significantly decreased, the Bcl-2/Bax ratio was downregulated, and the cleaved caspase-3 level was increased. Phosphorylation of MAPKs, including ERKs, JNKs, and p38, was upregulated. Treatment with vitamins C and E reversed the damage induced by PM2.5 exposure. These results suggest that PM2.5 from automobile exhaust disrupted spermatogenesis via ROS-mediated MAPK pathways, and that a combined vitamin C and E intervention effectively mitigated toxicity in the male reproductive system.

Chlorinated biphenyls effect on estrogen-related receptor expression, steroid secretion, mitochondria ultrastructure but not on mitochondrial membrane potential in Leydig cells. Cell Tissue Res 2017; 369:429-444.

Abstract
To characterize polychlorinated biphenyls (PCBs) action on Leydig cells, PCBs congeners, low-chlorinated (delor 103; d103) and high-chlorinated ones (delor 106; d106) were selected. The cells were treated according to PCBs dose (d103 or d106 0.2 ng/ml in low doses:, or 2 ng/ml in high doses) and type (d103 + d106 in low doses or 103 + 106 in high doses). After 24 h treatment with PCBs, a distinct increase in estrogen-related receptors (ERRs type α, β and γ) expression was revealed. However, the dose- and type-dependent PCBs effect was mostly exerted on ERRα expression. A similar increase in ERRs expression was demonstrated by estradiol but not testosterone, which was without an effect on ERRs. PCBs caused no decrease in the membrane potential status of Leydig cells (either in dose or type schedule) but had severe effects on the mitochondria number and structure. Moreover, PCBs markedly increased calcium (Ca2+) concentration and sex steroid secretion (both androgens and estrogens were elevated). These findings suggest a similar estrogenic action of PCBs congeners (d103 and d106) on Leydig cell function. We report dose- and type-specific effects of PCBs only on Leydig cell ERRs expression. Both delors showed common effects on the mitochondria ultrastructural and functional status. Based on our results, ERRα seems to be the most sensitive to hormonal modulation. The increases in Ca2+ and sex steroid secretion may be due to the activation of ERRs by PCBs binding and/or direct effect of PCBs on ERRs mRNA/protein expression. Nevertheless, to confirm the existence of possible relationships between ERRs signaling (including PCBs as ligands) and mitochondria function in Leydig cells, further intensive studies are needed.

Abstract
The study was conducted to investigate the protective role of α-tocopherol against polychlorinated biphenyls (PCBs) induced effect in Sertoli cell function of F1 prepuberal rats. Dams were grouped into six; each group consists of six animals. Group 1-control treated with corn oil as vehicle, group II- 0.5mgPCBs/kg bw/day, group III- 0.5mgPCBs/kg bw/day with α-tocopherol (50mg α-tocopherol/kg bw/day), group IV- 1mgPCBs/kg bwt/day, group V- 1mgPCBs/kg bw/day with α-tocopherol (50mg α-tocopherol/kg bw/day) and group VI - α-tocopherol alone treated orally from postpartum day1-20. Male offspring rats were euthanized on post natal day 21. Testes were collected for the histological examination and Sertoli cell isolation. The protein levels of follicle-stimulating hormone receptor, androgen binding protein, androgen receptor, estrogen receptor α & β, Inhibin-β, transferrin, claudin-11, occludin, E-cadherin, connexin-43, c-fos, c-jun, SF1, USF1 & 2 were studied using western blot method. The testicular architecture was affected in the PCBs exposed rats but this effect was restored by α-tocopherol supplementation. PCBs decreased the protein levels of FSHR, AR, ABP, ERα & β, transferrin, claudin-11, occludin, E-cadherin, connexin-43, c-fos, c-jun, SF1, USF1 & 2 whereas inhibin-β protein level was found to be increased in Sertoli cells. These results suggested that α-tocopherol has ameliorative role against PCBs induced testicular Sertoli cell dysfunction in F1 progeny.

Abstract
Polychlorinated biphenyls (PCBs) are ubiquitous and persistent environmental contaminants that disrupt endocrine function in biological systems, especially in the male reproductive system. Previous studies on the reproductive toxicity of PCBs have focused on the impairment of spermatogenesis, disruption of steroidogenesis, decreased sperm number, and infertility. Aroclor 1242 is a commercial mixture with an average of 42% chlorine by weight. The purpose of the present study was to elucidate the hazardous effects of Aroclor 1242 on Leydig cells through an evaluation of cell viability, lipid peroxidation, hydroxyl radicals, H2O2 production, antioxidant enzymes, and steroidogenic enzymes. Leydig cells were exposed to Aroclor 1242 for 24 h under basal and luteinizing hormone-stimulated conditions at different concentrations (ranging from 10−16 M to 10−6 M). After incubation, Leydig cells were measured for cell viability, lipid peroxidation, reactive oxygen species (hydroxyl radical and H2O2), antioxidant enzymes (catalase, superoxide dismutase, glutathione peroxidase, and glutathione-S-transferase), and steroidogenic enzymes (3β-hydroxysteroid dehydrogenase [HSD] and 17β-HSD). The results showed that cell viability was reduced only at Aroclor 1242 concentrations of 10−6 M and 10−8 M, whereas lipid peroxidation and reactive oxygen species increased relative to the concentration. Furthermore, antioxidant systems and steroidogenesis were interrupted to varying degrees, relative to the concentration. These findings suggest that exposure to Aroclor 1242 at high concentrations may result in detrimental effects to Leydig cell homeostasis. In addition, Aroclor 1242 may impair steroidogenesis, especially testosterone biosynthesis, by inhibiting two important steroidogenic enzymes.

Abstract
Background The present study was designed to investigate the protective effect of aqueous date extract (ADE) against the dichloroacetic acid (DCA)-induced testicular injury in rats. Methods Forty-eight male Wistar rats were randomly divided into six groups of eight: group I served as the control; group II was given ADE (4 ml/kg) by gavage; groups III and IV received DCA at 0.5 and 2 g/L drinking water, respectively; and groups V and VI received DCA at 0.5 and 2 g/L drinking water, respectively, before ADE administration. The experiment was performed for two months. Results Results showed that the absolute weights of testes and epididymis were decreased following the DCA administration. The testosterone, FSH and LH levels were also decreased. Severe histopathological changes in testes were observed including degeneration of seminiferous tubules and depletion of germ cells. These changes were associated with alterations of oxidative stress markers. Levels of lipid peroxidation and SOD and CAT activities were increased, while activity of GPx and GSH levels were decreased. Pretreatment with ADE has effectively alleviated the oxidative stress induced by DCA thereby restoring these parameters to normal values. Conclusions These results suggest that ADE has a protective effect over DCA-induced oxidative damage in rat testes.

Abstract
Defective sperm function has been identified as the most common cause of infertility. The objective of this study was to review recent findings on the effects of various antioxidants on male fertility. High amounts of poly unsaturated fatty acid are found in the mammalian spermatozoa membranes, thereby making them susceptible to lipid peroxidation. Although, free radicals and reactive oxygen species (ROS) play major roles in reproduction, they are strongly associated with oxidative stress. Furthermore, factors such as obesity, inflammation, pollutants and cigarette smoking are negatively correlated with spermatogenesis. Endogenous antioxidants system exists to mediate these damages. In a normal physiological state, the seminal plasma contains antioxidant enzyme mechanism that is capable of quenching these ROS as well as protecting the spermatozoa against any likely damage. However, high level of ROS triggered by inflammatory cells and oxidation of fatty acid in obese subjects may down play antioxidant mechanism resulting in oxidative stress. Evaluation of such oxidative stress is the first step in the treatment of male infertility through administration of suitable antioxidant. Notably, antioxidant such as vitamin E and C, carotenoids and carnitine have been found beneficial in restoring a balance between ROS generation and scavenging activities. There are emerging evidences that herbal products can also boost male reproductive functions. Nonetheless, a good lifestyle, regular exercise, avoidance of stress and observing safety rules at work are habits that can reverse male infertility.

Abstract
PURPOSE Polychlorinated biphenyls (PCBs) are persistent and bioaccumulative environmental toxicants acting as endocrine disruptors. Many researches evidenced that PCBs affect the male reproductive system in adult rats and it can transfer from mother to offspring through milk. We investigated whether the lactational exposure to PCBs affects the Sertoli cell function in F1 offspring. METHODS Dams were orally treated with different doses of PCB-Aroclor 1254 (1, 2 and 5 mg/kg bw/day, respectively) from postpartum day 1-20. Male offspring rats were killed on PND 21 and PND 60. Testes were used both for histological study and to isolate Sertoli cell. Serum and testicular interstitial fluid (TIF) levels of testosterone, ABP and estradiol were analyzed by ELISA method. The mRNA and protein expressions of follicle-stimulating hormone (FSHR), androgen-binding protein (ABP), Inhibinβ, androgen receptor (AR) and estrogen receptor (ERβ) were studied using real-time PCR and immunoblotting, respectively. RESULTS The testicular architecture was altered in PCB-treated groups of both prepuberal and puberal rats. Testosterone, estradiol and androgen-binding protein levels were altered in both serum and TIF in PCB treated groups. The gene expression level of FSHR, ABP, ERβ and AR was decreased in a dose-dependent manner, whereas Inhibinβ gene expression level was increased in PCB-treated groups. CONCLUSION Lactational exposure to PCB affects both the histoarchitecture of testis, Sertoli cell maker and functional regulators in both prepuberal and puberal F1 male progeny.

Abstract
Cadmium (Cd) is the most prevalent toxic metal present in livestock feed; therefore, the present study aimed to examine the ameliorative effects of grape seed extract (GSE) on cadmium chloride (CdCl2)-induced testicular dysfunction of Wistar rats. Male adult Wistar rats (40 rats; n=10/group) were divided into four equal groups. Group one was used as a control, and was given ad libitum access to food and water. Groups 2–4 were treated with CdCl2 [5 mg/kg body weight (BW)], GSE (400 mg/kg BW, orally), and GSE plus CdCl2, respectively. Blood and testicular tissues were collected and assayed for biochemical and histopathological changes, respectively. Testicular genes were expressed using semi-quantitative RT-PCR analysis. The results of the present study demonstrated that there was a decrease in serum testosterone levels following CdCl2 toxicity, which were normalized after GSE co-administration. Furthermore, CdCl2 significantly increased the serum levels of malondialdehyde, and decreased levels of antioxidants. At the histopathological level, the testes of the CdCl2 group exhibited congestion, edema in the interstitial blood vessels, irregular arrangement of the epithelial lining of the seminiferous tubules, and degeneration and sloughing of the spermatogenic cells, which accumulated in the center of the seminiferous tubules. Such pathological alterations were ameliorated following treatment with GSE in the CdCl2 plus GSE group. The immunohistochemical expression of B-cell lymphoma 2-associated X protein was high in the CdCl2 group, and low in the control and GSE groups. Co-treatment with GSE and CdCl2 exhibited ameliorative effects on the immunoreactivity of B-cell lymphoma 2-associated X protein. CdCl2 toxicity induced a significant downregulation in the mRNA expression levels of cytochrome P450 cholesterol side-chain cleavage enzyme, cytochrome P450 17A1, 3β-hydroxysteroid dehydrogenase (3β-HSD), 17β-HSD, androgen receptor, steroidogenic acute regulatory protein, and follicle-stimulating hormone receptor. GSE administration exhibited a stimulatory effect on steroidogenesis-associated enzymes, and co-treatment with GSE and CdCl2 normalized and upregulated the mRNA expression levels of these examined genes. This study concluded that GSE has beneficial protective effects against the deleterious effects of CdCl2 on the testis.

Abstract
CONTEXT PCB 77 (3,3',4,4'-tetrachlorobiphenyl), a non-ortho congener with planar configuration, has been identified as potential endocrine disrupter capable to increase the risk of reproductive and developmental failure. OBJECTIVE In the present study, in vitro PCB 77 toxic potential, apoptosis induction and cell cycle alterations were investigated to reveal direct toxic effects on ovarian cells. METHODS Chinese Hamster Ovary (CHO-K1) cell line was selected as a model system and decreased cell viability was confirmed by application of four bioassays. Cellular morphology and quantitative analysis of apoptotic, necrotic and viable cells were determined with fluorescent microscopy and cell cycle phase distributions by measuring DNA content using flow cytometry. RESULTS We have indicated Trypan blue exclusion assay as the most sensitive for quantifying cytotoxicity of PCB 77 in terms of IC50 values, while the results obtained by other methods pointed to a possible localized effect on the lysosomes/endosomes (Neutral red), compromised intracellular metabolic processes (MTT) and possible interferation with the rate of protein synthesis (Kenacid blue). The loss of cell viability, as a consequence of treatment with 10-100 μM PCB 77, fundamentally was due to induction of apoptosis with observed common series of specific morphological changes characteristic to apoptotic phenomenon. The level of alterations of normal cell cycle progression was low without significant changes at analyzed time intervals. CONCLUSION These results indicate toxic outcomes of PCB 77 at ovarian cellular level with regard to potential direct adverse effects to female reproductive system.

Abstract
Among Yoruba herbalists (Southwest Nigeria), hot water infusion of Mangifera indica L. (芒果 Máng Guǒ) stem bark is reputedly used for the treatment of fever, jaundice and liver disorders. The present study, therefore, investigates the protective effects and mechanism(s) of chemopreventive and curative effects of 125–500 mg/kg/day of Mangifera indica aqueous stem bark extract (MIASE) in acute CCl4-induced liver damage in rats. Rats were treated intragastrically with 125, 250 and 500 mg/kg/day of MIASE for 7 days before and after the administration of CCl4 (3 ml/kg of 20% CCl4, i.p.). The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total protein (TP), albumin (ALB), triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-c), low density lipoprotein cholesterol (LDL-c), total bilirubin (TB), conjugated bilirubin (CB) and fasting blood glucose (FBG) levels were estimated. In addition, hepatic tissue reduced glutathione (GSH) and the malondialdehyde (MDA) concentrations, catalase (CAT), superoxide (SOD) activities in the hepatic homogenate, and histopathological changes in the rat liver sections were determined. Preliminary qualitative phytochemical screening for bioactive compounds in MIASE was also conducted. Results showed that oral treatment with 125–500 mg/kg/day of MIASE significantly attenuated the increase in serum ALT, AST, ALP, FBG, TB, CB and LDL-c levels in acute liver injury induced by CCl4 treatment. Findings also revealed significant elevations in the serum TC, TG, HDL-c, TP and ALB levels. There was marked architectural remodeling in the hepatic lesions of hepatocyte vacuolation and centrilobular necrosis induced by CCl4 treatment, coupled with significant weight loss. MIASE also markedly enhanced SOD and CAT activities while reducing MAD formation; and increased GSH concentration in the hepatic homogenate compared with untreated CCl4-intoxicated group, with more protection offered in the curative than the chemopreventive models of CCl4 hepatotoxicity. Thus, these results indicate that MIASE has a profound protective effect against acute CCl4-induced hepatotoxicity in rats, which may be due to its free radicals scavenging effect, inhibition of lipid peroxidation, and its ability to increase antioxidant activity.

Abstract
Quinalphos (QP) is speculated to cause endocrine disruption through the generation of reactive oxygen species (ROS) by oxidative stress (OS). Exposure of QP decreased testosterone level considerably which resulted in reduced viable sperms in mice. The QP induced toxicity is initiated by the formation of free radicals as it is evidenced from the increased Lipid peroxidation (LPO) and diminution of antioxidant enzymes in testicular tissue. Increased serum cholesterol and reduced testicular cholesterol indicated the inhibition of cholesterol transport and biosynthesis in testicular tissues. Lack of cholesterol in testicular tissue impaired the steroidogenesis by down-regulating the expression of StAR protein, Cytochrome P450, 3β-HSD and 17β-HSD leading to reduced testosterone level. Treatment of Commelina benganlensis (CBE) and Cissus quadrangularis (CQE) significantly recovered the alterations in antioxidant profiles as well as increased LPO, thereby recovering the decreased mRNA expression levels of intermediate enzymes. However, CQE effectively protected the OS and prevented the inhibition of steroidogenesis thereby preventing male infertility.

Abstract
This study was performed to investigate the protective and therapeutic effects of
resveratrol (RES) against CdCl2-induced toxicity in rat testes. Seven
experimental groups of adult male rats were formulated as follows: A) controls+NS, B)
control+vehicle (saline solution of hydroxypropyl cyclodextrin), C) RES treated, D)
CdCl2+NS, E) CdCl2+vehicle, F) RES followed by CdCl2
and M) CdCl2 followed by RES. At the end of the protocol, serum levels of FSH,
LH and testosterone were measured in all groups, and testicular levels of TBARS and
superoxide dismutase (SOD) activity were measured. Epididymal semen analysis was
performed, and testicular expression of Bcl-2, p53 and Bax was assessed by RT-PCR. Also,
histopathological changes of the testes were examined microscopically. Administration of
RES before or after cadmium chloride in rats improved semen parameters including count,
motility, daily sperm production and morphology, increased serum concentrations of
gonadotropins and testosterone, decreased testicular lipid peroxidation and increased SOD
activity. RES not only attenuated cadmium chloride-induced testicular histopathology but
was also able to protect against the onset of cadmium chloride testicular toxicity.
Cadmium chloride downregulated the anti-apoptotic gene Bcl2 and upregulated the expression
of pro-apoptotic genes p53 and Bax. Resveratrol protected against and partially reversed
cadmium chloride testicular toxicity via upregulation of Bcl2 and downregulation of p53
and Bax gene expression. The antioxidant activity of RES protects against cadmium chloride
testicular toxicity and partially reverses its effect via upregulation of BCl2 and
downregulation of p53 and Bax expression.

Abstract
The impact of ascorbic acid supplementation against ethanol induced Leydig cell toxicity was studied in guinea pigs. Male guinea pigs were exposed to ethanol (4g/kgb.wt.) for 90 days. After 90 days, ethanol administration was completely stopped and animals in the ethanol group were divided into abstention group and ascorbic acid supplemented group (25mg/100gb.wt.) and those in control group were maintained as control and control+ascorbic acid group. Ethanol administration reduced the serum testosterone and LH (luteinising hormone) levels and elevated estradiol levels. Cholesterol levels in Leydig cell were increased whereas the mRNA and protein expressions of StAR (steroidogenic acute regulatory) protein, cytochrome P450scc (cytochrome p450side chain cleavage enzyme), 3β-HSD (3β-hydroxysteroid dehydrogenase), 17β-HSD (17β-hydroxysteroid dehydrogenase) and LH receptor were drastically reduced. Administration of ascorbic acid resulted in alteration of all these parameters indicating enhanced recovery from ethanol induced inhibition of Leydig cell steroidogenesis. Although abstention could also reduce the inhibition of steroidogenesis, this was lesser in comparison with ascorbic acid supplemented group.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional remedies from plants have been use to treat male reproductive related disorders for ages in South Africa. AIM This study reviewed the current status of medicinal plants used in male reproductive healthcare as well as their effectiveness as a mode of treatment. METHODOLOGY A detailed literature search was done by consulting books, peer-reviewed papers, scientific databases such as Scopus, Science direct and PubMed, and Google scholars. Keywords such as aphrodisiacs, conception, erectile dysfunction, fertility, infertility and sterility in relation to medicinal plants were used during the search. Plant species were selected based on their traditional use in different aspects of male reproductive healthcare. RESULTS A total of 61 plants species were found to be used in treating male impotency or as aphrodisiacs. However, only six species have been evaluated scientifically and these plants showed significant activities either in promoting conception by improving fertility and promoting erection or in contraception by decreasing sperm motility, virility and membrane integrity. CONCLUSION The importance of herbal products in the treatment of male infertility and related sexual disorders is undeniable. Scientific evaluations of the six species have proved the empirical use of these plants in the improvement of male sexual disorders as well as validating their traditional uses.

Abstract
The purpose of this study was to investigate the effects of vitamin E on reproductive hormones and testis structure in mice treated with 2,3,7,8-tetrachlorodibenzo- p-dioxin (TCDD). Five experimental groups of a combination of TCDD and vitamin E were designed as follows: 0 ng/kg/d and 0 mg/kg/d (control group), 100 ng/kg/d and 0 mg/kg/d (Group I), 100 ng/kg/d and 20 mg/kg/d (Group II), 100 ng/kg/d and 100 mg/kg/d (Group III), and 100 ng/kg/d and 500 mg/kg/d (Group IV) respectively. Vitamin E and TCDD were given by oral gavage for 7 weeks. The results demonstrated that TCDD decreased the levels of brain gonadotropin releasing hormone (GnRH), testis luteinizing hormone (LH) and follicle stimulating hormone (FSH), serum testosterone and testis spermatozoa number, and damaged testis structure. Vitamin E at 20 mg/kg alleviated the decrease of GnRH; vitamin E at 20, 100, and 500 mg/kg antagonized the decline of LH and FSH; vitamin E at 20 and 100 mg/kg reversed the decrease of testosterone and spermatozoa number; and vitamin E at 100 mg/kg decreased the damage of the testis structure caused by TCDD. The results indicate that vitamin E antagonizes the reproductive endocrine toxicity and alleviates the changes in testicular structure caused by TCDD.

Abstract
Dioxins like 2,3,7,8 tetrachlorodibenzo-p—dioxin (TCDD) impair male reproductive system by increasing the generation of reactive oxygen species (ROS). Glucocorticoids have been found to suppress male reproductive function and also influence TCDD pathway. As stress is characterized by an increase in the level and activity of glucocorticoids, the present experiments were conducted to evaluate the effect of restraint stress on TCDDinduced testicular and epididymal toxicity. Adult male Wistar rats were subjected to either restraint stress (5 hours/day) or TCDD treatment (100 ng/kg b.w./day) or both for 15 days. Restraint stress or TCDD treatment raised the serum level of corticosterone and suppressed the testicular level of steroidogenic acute regulatory (StAR) protein and serum level of testosterone significantly. In the testis and epididymis, restraint stress or TCDD treatment raised the levels of lipid peroxidation and hydrogen peroxide and suppressed the activities of antioxidant enzymes significantly. In rats subjected to both restraint stress and TCDD treatment, a significant increase in the serum level of corticosterone and a significant decrease in the testicular level of StAR protein and serum level of testosterone were observed as compared to rats treated with TCDD alone. A significant increase in the levels of lipid peroxidation and hydrogen peroxide and a significant decrease in the activities of antioxidant enzymes were observed in the testis and epididymis of rats subjected to both restraint stress and TCDD treatment as compared to TCDD alone treated rats. Thus, restraint stress potentiates the adverse effects of TCDD on male reproductive organs.

Abstract
The aim of this study was to investigate the protective effect of 3-alkynyl selenophene (3-ASP) on acute liver injury induced by carbon tetrachloride (CCl(4)) and 2-nitropropane (2-NP) in rats. On the first day of treatment, the animals received 3-ASP (25 mg/kg, p.o.). On the second day, the rats received CCl(4) (1 mg/kg, i.p.) or 2-NP (100 mg/kg, p.o.). Twenty-four hours after CCl(4) or 2-NP administration, the animals were euthanized, and their plasma and liver were removed for biochemical and histological analyses. The histological analysis revealed extensive injury in the liver of CCl(4)-exposed and 2-NP-exposed rats, which was attenuated by 3-ASP. 3-ASP significantly attenuated (1) the increase in plasmatic aspartate and alanine aminotransferase activities and lipid peroxidation levels induced by CCl(4) and 2-NP; (2) the inhibition of δ-aminolevulinic dehydratase activity caused by 2-NP; and (3) the decrease in ascorbic acid (AA) levels and catalase (CAT) activity caused by CCl(4). AA levels and CAT activity remained unaltered in the liver of rats exposed to 2-NP. The protective effect of 3-ASP on acute liver injury induced by CCl(4) and 2-NP in rats was demonstrated.

Abstract
Polychlorinated biphenyls (PCBs) are environmental pollutants that are quite toxic to biological systems. This study examined the inhibitory effect of PCB126 and PCB114 on testicular steroidogenesis in male rats. Male Sprague Dawley rats received weekly intraperitoneal injections of PCB126 (0.2 mg/kg) or PCB114 (20 mg/kg) or vehicle (corn oil). Animals from each group were sacrificed at 2, 5 and 8 weeks after the injections. Blood and testis tissue samples were collected for the hormone assay, Western blotting and reverse transcriptase polymerase chain reaction (RT-PCR). The testosterone, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels were assayed, and the expression levels of the mRNA and proteins associated with the testosterone biosynthesis pathway were measured to determine the effect of PCB126 and PCB114 on testicular steroidogenesis. The results showed that the testis weight was significantly higher in the PCB126-treated rats given eight shots. Moreover, the serum testosterone levels were significantly lower in the PCB126 and PCB114-treated groups than the control. The transcription and translation levels of P45017α and P450scc were significantly lower in the PCB126-treated groups than the control. These results suggest that PCB126 may affect testicular steroidogenesis by downregulating P45017α, P450 scc and have inhibitory effect on the testicular functions.

Abstract
The study was conducted to investigate the effects of vitamin E on NK cell activity and lymphocyte proliferation in tr eated female mice by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). In chronic TCDD trial, 45 mice were divided into 5 groups, and the levels of TCDD and vitamin E were 0 and 0, 100 and 0, 100 and 20, 100 and 100, and 100 ng/kg/d and 500 mg/kg/d, respectively. In acute TCDD trial, 24 mice were divided into three groups, and the levels of TCDD and vitamin E were 0 and 0, 30 and 0, and 30 microg/kg and 100 mg/kg, respectively. The results showed chronic TCDD-treatment caused decrease tendencies of spleen NK cell activity and lymphocyte proliferation, and vitamin E 100mg/kg alleviated the decreases tendencies caused by chronic TCDD-treatment, and the lymphocyte proliferation in the group given vitamin E 100mg/kg was significantly higher than that of the chronic TCDD-treated group. Acute TCDD-treatment suppressed the NK cell activity and lymphocyte proliferation, and vitamin E 100mg/kg significantly alleviated the decrease caused by acute TCDD-treatment. These results suggested that TCDD resulted in immunotoxicity, and the toxicity of acute TCDD-treatment was severe compared with chronic TCDD, while vitamin E alleviated the immunotoxicity from TCDD.

Abstract
Abstract
For millions of couples, the inability to have a child is a personal tragedy and a large proportion of childless people are confronted with social stigmatization (blame) and personal frustration. Formerly assigned to women, infertility of a couple is nowadays equitably distributed between the two sexes. Among the methods used to treat male infertility problems, medicinal plants have been used empirically as extracts, decoctions, fractions or semi-purified compounds. These herbal products are used in the treatment of a dysfunctioning of the libido, sexual asthenia, erection, and sperm disorders. Pharmacological activities of many of these plants have been shown in vitro using cells, in vivo (on laboratory animals) and human studies. For instance, extracts of Panax ginseng, Panax quinquefolius and Lepidium meyenii have shown positive effects on sexual desire; while extracts of Astragalus membranaceus, Asparagus racemous, Withania somnifera, Andrographis paniculata and Acanthopanax senticosus improved sperm parameters. Plants provide a treatment option that is affordable and available for infertile couples, and phytotherapy is an essential form of treatment in our health system. However, herbal products are still anarchically used in many regions and countries, and a great proportion of medicinal plants used traditionally to solve male reproductive disorders have not yet been scientifically evaluated. Therefore in this review, we have summarized most of the data dealing with the effects of plant extracts on mammalian reproductive functions.

Abstract
Successful spermatogenesis is dependent on the proper attachment of developing germ cells to Sertoli cells. Manipulation of these interactions by drugs like Adjudin can hamper the development of germ cells and lead to conditions of temporary infertility. Although studies have shown the contraceptive potential of Adjudin, much is not known about its action in the testis. In this study, we sought to investigate the effect of Adjudin on the oxidative status of mammalian testis. Adult male rats were administered with a single dose of Adjudin (50 mg/kg body weight) by oral gavage and were killed at 1, 2, 4, 7, 15, or 30 days of treatment. Adjudin caused a significant increase in the production of hydrogen peroxide and lipid peroxidation from 4 to 7 days after treatment. There was a significant decrease in the activities of anti-oxidant enzymes superoxide dismutase, catalase, glutathione peroxidase and glutathione S-transferase from 4 to 7 days after treatment with Adjudin. However, the state of oxidative stress was less pronounced from 15 to 30 days after Adjudin treatment. The level of androgen binding protein (ABP) remained unchanged following Adjudin treatment. These results show that there is an induction of oxidative stress accompanying adherens junction restructuring which suggests a role for reactive oxygen species in the regulation of these testicular junctions. However, transient elevation in reactive oxygen species levels did not affect androgen transport.

Abstract
Triclosan (TCS), a chlorophenol, is widely used as a preservative in different types of commercial preparations. The reports on TCS-mediated endocrine disruption are controversial and the present study aimed to elucidate the probable mode of action of TCS as an antiandrogenic compound using a robust study design. Male albino rats, Rattus norvegicus, were treated with three doses of triclosan for a period of 60 days followed by the analysis of various biochemical parameters. RT-PCR analysis demonstrated a significant decrease in mRNA levels for testicular steroidogenic acute regulatory (StAR) protein, cytochrome P450(SCC), cytochrome P450(C17), 3beta-hydroxysteroid dehydrogenase (3beta-HSD), 17beta-hydroxysteroid dehydrogenase (17beta-HSD) and androgen receptor (AR) in TCS treated rats (p<0.05). TCS also induced a perturbed translation of testicular StAR, and AR proteins as shown by Western blot analysis in treated groups of rats. A reduced level of StAR was further indicated by immunohistochemistry in testicular Leydig cells. Further, there was a significant decrease (p<0.05) in the level of serum lutenizing hormone (LH), follicle stimulating hormone (FSH), cholesterol, pregnenolone, and testosterone. In vitro assays demonstrated more than 30% decrease in testicular 3beta-HSD and 17beta-HSD enzyme activities in treated group of animals. Extensive histopathological malformations were observed in the testis and sex accessory tissues of the treated rats. Overall this study showed that TCS decreased the synthesis of androgens followed by reduced sperm production in treated male rats which could be mediated by a decreased synthesis of LH and FSH thus involving hypothalamo-pituitary-gonadal axis.
