Edelsztein NY, Rey RA. Importance of the Androgen Receptor Signaling in Gene Transactivation and Transrepression for Pubertal Maturation of the Testis. Cells 2019; 8:E861.

Abstract
Androgens are key for pubertal development of the mammalian testis, a phenomenon that is tightly linked to Sertoli cell maturation. In this review, we discuss how androgen signaling affects Sertoli cell function and morphology by concomitantly inhibiting some processes and promoting others that contribute jointly to the completion of spermatogenesis. We focus on the molecular mechanisms that underlie anti-Müllerian hormone (AMH) inhibition by androgens at puberty, as well as on the role androgens have on Sertoli cell tight junction formation and maintenance and, consequently, on its effect on proper germ cell differentiation and meiotic onset during spermatogenesis.

Abstract
Leydig cells (LCs) are the primary source of testosterone in the testis, and testosterone deficiency caused by LC functional degeneration can lead to male reproductive dysfunction. LC replacement transplantation is a very promising approach for this disease therapy. Here, we report that human adipose derived stem cells (ADSCs) can be differentiated into Leydig-like cells using a novel differentiation method based on molecular compounds. The isolated human ADSCs expressed positive CD29, CD44, CD59 and CD105, negative CD34, CD45 and HLA-DR using flow cytometry, and had the capacity of adipogenic and osteogenic differentiation. ADSCs derived Leydig-like cells (ADSC-LCs) acquired testosterone synthesis capabilities, and positively expressed LC lineage-specific markers LHCGR, STAR, SCARB1, SF-1, CYP11A1, CYP17A1, HSD3B1 and HSD17B3 as well as negatively expressed ADSC specific markers CD29, CD44, CD59 and CD105. When ADSC-LCs labelled with lipophilic red dye (PKH26) were injected into rat testes which were selectively eliminated endogenous LCs using ethylene dimethanesulfonate (EDS, 75 mg/kg), the transplanted ADSC-LCs could survive and function in the interstitium of testes, and accelerate the recovery of blood testosterone levels and testis weights. These results demonstrated that ADSCs could be differentiated into Leydig-like cells by few defined molecular compounds, which might lay the foundation for further clinical application of ADSC-LC transplantation therapy.

Abstract
The sperm quality is a vital economical requisite of poultry production. Our previous study found non-thermal dielectric barrier discharge plasma exposure on fertilized eggs could increase the chicken growth and the male reproduction. However, it is unclear how plasma treatment regulates the reproductive capacity in male chickens. In this study, we used the optimal plasma treatment condition (2.81 W for 2 min) which has been applied on 3.5-day-incubated fertilized eggs in the previous work and investigated the reproductive performance in male chickens aged at 20 and 40 weeks. The results showed that plasma exposure increased sperm count, motility, fertility rate, and fertilization period of male chickens. The sperm quality-promoting effect of plasma treatment was regulated by the significant improvements of adenosine triphosphate production and testosterone level, and by the modulation of reactive oxygen species balance and adenosine monophosphate-activated protein kinase and mammalian target of rapamycin pathway in the spermatozoa. Additionally, the plasma effect suggested that DNA demethylation and microRNA differential expression (a total number of 39 microRNAs were up-regulated whereas 53 microRNAs down-regulated in the testis) regulated the increases of adenosine triphosphate synthesis and testosterone level for promoting the chicken sperm quality. This finding might be beneficial to elevate the fertilization rate and embryo quality for the next generation in poultry breeding.

Abstract
Cadmium is a heavy metal that is toxic to humans and the reproductive system. The present study aimed to investigate the mechanisms of cadmium-induced reproductive toxicity in a male Institute of Cancer Research mouse model of cadmium poisoning. Changes in luteinizing hormone receptor (LHR), 17α-hydroxylase and endothelial nitric oxide (NO) synthase (eNOS) expression levels were examined. A total of 24 male mice (4-week-old) were randomly divided into four groups (normal control group and low, medium and high cadmium groups) and subjected to gavage treatment with normal saline or cadmium-containing saline solutions for 8 weeks prior to sacrifice. To assess testicular injury, serum androgen levels were determined by ELISA, testicular tissue pathological changes were evaluated using hematoxylin and eosin staining. In addition, LHR, 17α-hydroxylase and eNOS expressions levels were examined by western blotting, and apoptosis was examined with a terminal deoxynucleotidyl transferase dUTP nick end labeling assay. The results demonstrated that the severity of testes injury increased with cadmium concentration. In addition, LHR, 17α-hydroxylase and eNOS expression levels increased with low and medium concentrations of cadmium; however, they were decreased following treatment with high concentrations of cadmium. The results from the present study demonstrated that cadmium altered LHR, 17α-hydroxylase and eNOS expression levels in testicular stromal cells, which may impact testosterone synthesis. Furthermore, NO was suggested to be involved in cadmium-induced testicular injury by measurements of eNOS expression in testicular stromal cells.

Abstract
Endocrine disrupting chemicals (EDCs) in the environment are considered to be a contributing factor to the decline in the sperm quality. With growing evidence of the harmful effects of EDCs on the male reproductive system, we tested the hypothesis that prenatal exposure to an environmentally relevant phthalate mixture adversely affects reproductive outcomes and androgen synthesis. In this study, an environmentally relevant composition of phthalates (15% DiNP, 21% DEHP, 36% DEP, 15% DBP, 8% DiBP, and 5% BBzP) that were detected in urine samples of pregnant women in Illinois, United States, was used. Pregnant CD-1 mice (F0) were orally dosed with a vehicle or the phthalate mixtures (20 µg/kg/day, 200 µg/kg/day, 200 mg/kg/day, or 500 mg/kg/day) from gestational day 10.5 to the day of birth. Then, the indices of the reproductive function of the F1 males born to these dams were assessed. Those male mice prenatally exposed to the phthalate mixture had smaller gonads, prostates and seminal vesicles, especially in the 20 µg/kg/day and 500 mg/kg/day phthalate mixture groups, compared to the controls. Importantly, at the age of 12 months, those prenatally exposed mice had significantly lower serum testosterone concentrations accompanied by the decreased mRNA expression of testicular steroidogenic genes (StAR, Cyp11, and Cyp17) and impaired spermatogenesis. Taken together, this study found that prenatal exposure to environmentally relevant doses of a phthalate mixture caused a life-long impact on the reproduction in male mice.

Abstract
Perfluoroalkyl acids (PFAAs) are widely used in industrial and commercial products and possess endocrine disrupting properties. Perfluorononanoic acid (PFNA), one of PFAAs, has been mainly reported to produce testicular toxicity in adult animals. The objective of the present study was to examine the effect of acute exposure of PFNA to prepubertal male Parkes (P) mice on spermatogenesis and testicular steroidogenesis, and to study the possible mechanism(s) of its action. PFNA (2 and 5 mg/kg) was orally administered to male P mice for 14 days from postnatal day 25-38. Histologically, testis in PFNA-treated mice showed non-uniform diverse degenerative changes in the seminiferous tubules; both normal and affected tubules were seen in the same testicular sections. The treatment caused a reduction in intra-testicular and serum testosterone levels accompanied by a decrease in testicular expression of SF1, StAR, CYP11A1, and 3β- and17β-HSD. Further, the activity of antioxidant enzymes and expression of Nrf2 and HO-1 in the testis were markedly decreased, while the level of lipid peroxidation and expression of IKKβ, NF-κB and caspase-3 were significantly increased in testis of PFNA-treated mice. There was also a decrease in PCNA expression and in PCNA-index and an increase in TUNEL-positive germ cells in testes of PFNA-treated mice. In conclusion, the results suggest that PFNA exposure to prepubertal male mice altered antioxidant enzymes activity and Nrf2-HO-1 signaling, leading to oxidative stress and a decrease in testosterone biosynthesis in the testis; these changes, in turn, caused increased apoptosis and decreased proliferation of germ cells, thereby suppression of spermatogenesis.

Abstract
Leydig cells (LCs) play crucial roles in producing testosterone, which is critical in the regulation of male reproduction and development. Low levels of testosterone will lead to male hypogonadism. LC transplantation is a promising alternative therapy for male hypogonadism. However, the source of LCs limits this strategy for clinical applications. Thus far, others have reported that LCs can be derived from stem cells by gene transfection, but the safe and effective induction method has not yet been reported. Here, we report that Leydig-like cells can be derived from human induced pluripotent stem cells (iPSCs) using a novel differentiation protocol based on molecular compounds. The iPSCs-derived Leydig-like cells (iPSC-LCs) acquired testosterone synthesis capabilities, had the similar gene expression profiles with LCs, and positively expressed Leydig cell lineage-specific protein markers LHCGR, STAR, SCARB1, SF-1, CYP11A1, HSD3B1, and HSD17B3 as well as negatively expressed iPSC-specific markers NANOG, OCT4, and SOX2. When iPSC-LCs labeled with lipophilic red dye (PKH26) were transplanted into rat testes that were selectively eliminated endogenous LCs using EDS (75 mg/kg), the transplanted iPSC-LCs could survive and function in the interstitium of testes, and accelerate the recovery of serum testosterone levels and testis weights. Collectively, these findings demonstrated that the iPSCs were able to be differentiated into Leydig-like cells by few defined molecular compounds, which may lay the safer groundwork for further clinical application of iPSC-LCs for hypogonadism.

Abstract
Food Yellow 4 (FY4) is a lemon-yellow-colored synthetic organic azo dye, which is used widely for imparting pleasant and attractive appearance to foods and cosmetics. The present study aimed at evaluating the possible mechanism underlying the FY4-induced reprotoxicity in rats, and the potential supportive role of royal jelly (RJ) or cod liver oil (CLO), which is a natural remedy with several pharmacological benefits, against induced toxicity. Forty-eight male rats were divided into different groups-the control group, the CLO group (0.4 mL/kg), the RJ group (300 mg/kg), the FY4 group (500 mg/kg b.w.), and the co-treated groups (FY4 + CLO or FY4 + RJ). Semen analysis, serum hormones, and enzyme activities were estimated. Immunohistochemical staining was performed using anti-PCNA, anti-Sox 9, anti-STRA8, anti-DMC1, and anti-ssDNA antibody. The FY4 group exhibited a significant decrease in sperm concentration and motility percentage (%) and a substantial reduction in the TES and LH levels. Testicular LDH, ACP, and SDH were observed to be inhibited. Furthermore, co-localization of DMC1 and ssDNA, which reflected apoptotic induction in the leptotene and zygotene spermatocytes, respectively, was observed to have markedly elevated in the FY4 treated rats, with fewer PCNA-positive and SOX9-positive cells and higher ssDNA-positive cells in the seminiferous epithelium in comparison to the control groups. Interestingly, co-treatment with CLO or RJ exhibited healthy sperms and restored their features, activated the enzyme production, and raised the levels of sexual hormones. In addition, both RJ and CLO restored the features of the testicular tissue as observed under a light microscope, and limited the apoptosis as observed through antibody staining. Collectively, the results of the present study revealed that the co-administration of RJ or CLO with FY4 improved the biochemical, hormonal, and structural aspects of the testicular tissue in rats. Therefore, CLO and RJ may be considered promising agents that would be able to improve the testicular structure and function in the FY4-exposed individuals.

Abstract
Bisphenol A (BPA) is an endocrine-disrupting chemical (EDC) that is widely used in the manufacturing of plastics and inner linings of food cans. Previously, it was reported that BPA disturbed the sexual dimorphic nucleus of the hypothalamus and delaying the onset of puberty attributed to an estrogenic action. In addition, BPA during the perinatal period increased LH serum concentrations in male offspring of dams at doses below the reproductive NOAEL (No Observable Adverse Effect Level) based upon World Health Organization guidelines. Based upon these findings, the objective of this study was to (1) determine the effects of perinatal treatment with low doses of BPA on regulation of spermatogenesis in adult offspring and (2) elucidate molecular mechanisms involved in the pathogenesis of gonadal dysfunction. The expression of genes related to spermatogenesis was disrupted with adverse consequences on sperm production, reserves, and function. Both BPA treated groups exhibited reduction in sperm production and epithelial height of seminiferous tubules, accompanied by diminished integrity of the acrosome and plasma membrane, decreased mitochondrial activity and increased incidence of morphological abnormalities. The sperm transit time was also slower. However, only in the group receiving the higher BPA dose was transcript expression of genes affected (reduced Ar and increased Esr1). It is of interest that serum testosterone levels were elevated in the same group where Ar was decreased. Data suggest that exposure to low BPA doses during hypothalamic sexual differentiation period produces permanent deleterious effects on spermatogenesis in adulthood.

Abstract
Glioblastomas (GBM) are the most frequent and aggressive human brain tumors due to their high capacity to migrate and invade normal brain tissue. Epidemiological data report that GBM occur in a greater proportion in men than in women (3:2), suggesting the participation of sex hormones in the development of these tumors. It has been reported an increase in testosterone (T) levels in patients with GBM. In addition, androgen receptor (AR) is overexpressed in human GBM, and genetic silencing of AR, and its pharmacological inhibition, induce GBM cell death in vivo and in vitro. However, the role of T in proliferation, migration and invasion in human GBM cell lines has not been evaluated. We observed that T increased the number of U87, U251, and D54 cells derived from human GBM due to an increase in cell proliferation. This induction was blocked with flutamide, an antagonist of AR. T also induced migration and invasion of GBM cells that flutamide partially blocked. These data suggest that T through AR contributes to the progression of GBM by promoting proliferation, migration, and invasion.

Abstract
C1q-like 4 (C1QL4), a novel member of the C1q- and TNF-related protein family, was found to be highly expressed in rodent and human testis. However, the localization, developmental, and hormonally regulated expression and biologic function of C1ql4 in the testis have not been investigated. Here, we demonstrated that C1ql4 mRNA and protein levels in murine testes gradually increased from the postnatal period to the adult stage and were up-regulated by LH in vivo. In situ hybridization demonstrated that the distribution and expression levels of C1ql4 mRNA varied at different developmental stages, although C1ql4 mRNA was detected in the seminiferous tubule and interstitial Leydig cells. Recombinant C1QL4 did not affect cell proliferation but did increase testosterone production in TM3 Leydig cells, as well as in cultured seminiferous tubules. C1QL4-induced testosterone secretion in Leydig cells was accompanied by increased expression of steroidogenic acute regulatory (StAR) protein and steroidogenic enzymes. During this process, the c-Raf/extracellular signal-regulated protein kinase kinases 1 and 2/ERK1/2/mitogen- and stress-activated protein kinase-1 and cAMP/PKA/cAMP-responsive element binding protein signaling cascades were activated by C1QL4. The cell-adhesion GPCR brain-specific angiogenesis inhibitor 3 (BAI3), a putative receptor of C1QL4, was detected in the seminiferous tubule and interstitial Leydig cells during testicular development. Knockdown of Bai3 expression in Leydig cells led to a reduction in Star expression, accompanied by increases in phosphorylation of ERK1/2 and intercellular cAMP levels. However, C1QL4-induced StAR expression was not completely suppressed in the Bai3-deficient Leydig cells, and phosphorylation of ERK1/2 and intercellular cAMP levels were not significantly changed before and after C1QL4 stimulation. Our results suggested that although BAI3 played a role in C1QL4-induced steroidogenesis, there was an unidentified receptor that mediated C1QL4-activated testosterone secretion in Leydig cells through phosphorylation of ERK1/2 and up-regulation of intracellular cAMP levels. Taken together, our results showed, for the first time to our knowledge, that C1QL4 served as a novel acute regulator of testosterone secretion, and BAI3 functioned as a new receptor that is involved in steroidogenesis in Leydig cells. BAI3-independent ERK1/2 activation and cAMP activation mediated C1QL4-induced testosterone secretion. This study expanded the reproductive roles and mechanisms of C1QL4 and BAI3 signaling pathways.-Tan, A., Ke, S., Chen, Y., Chen, L., Lu, X., Ding, F., Yang, L., Tang, Y., Yu, Y.

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
Testicular macrophages (tMΦ) are the most abundant immune cells residing in the testis, an immune-privileged organ. TMΦ are known to exhibit different functions, such as protecting spermatozoa from auto-immune attack by producing immunosuppressive cytokines and trophic roles in supporting spermatogenesis and male sex hormone production. They also contribute to fetal testicular development. Recently, we characterized two distinct tMΦ populations based on their morphology, localization, cell surface markers, and gene expression profiling. Here, we focus and describe in detail the phenotypical distinction of these two tMΦ populations by fluorescence-activated cell sorting (FACS) using multicolor panel antibodies combining with high-resolution immunofluorescence (IF) imaging. These two techniques enable to classify two tMΦ populations: interstitial tMΦ and peritubular tMΦ.

Abstract
The inability of cultured primary Leydig cells to maintain luteinizing hormone (LH)-responsive testosterone formation in vitro for more than 3-5 days has presented a major challenge in testing trophic effects of regulatory factors or environmental toxicants. Our primary objective was to establish culture conditions sufficient to maintain LH-responsive testosterone formation by Leydig cells for at least a month. When isolated rat adult Leydig cells were cultured in DMEM/F12 and M199 culture medium containing insulin (10μg/ml), PDGFAA (10 ng/ml), lipoprotein (0.25 mg/ml), horse serum (1%) and a submaximal concentration of LH (0.2 ng/ml), the cells retained the ability to produce testosterone in vitro for at least 4 weeks. By using the longer-term culture conditions of this system, we were able to detect suppressive effects on testosterone production by low levels of the toxicant MEHP (mono-(2-ethylhexyl) phthalate), an active metabolite of the plasticizer DEHP, that were not detected by short-term culture.

Abstract
Testosterone has a variety of functions and is commonly used in older men to treat symptoms of hypogonadism, such as decreased libido, decreased mood and erectile dysfunction. Despite its positive effects on sexual function, it has a negative effect on fertility. Exogenous testosterone therapy can negatively affect the hypothalamic-pituitary gonadal axis and inhibit the production of follicle stimulating hormone and luteinizing hormone. The purpose of this review is to discuss the contraceptive properties of testosterone therapy and to discuss strategies to increase testosterone in men with the desire to preserve fertility.

Abstract
Chemical communication plays many key roles in mammalian reproduction, although attention has focused particularly on male scent signalling. Here, we review evidence that female chemical signals also play important roles in sexual attraction, in mediating reproductive competition and cooperation between females, and in maternal care, all central to female reproductive success. Female odours function not only to advertise sexual receptivity and location, they can also have important physiological priming effects on male development and sperm production. However, the extent to which female scents are used to assess the quality of females as potential mates has received little attention. Female investment in scent signalling is strongly influenced by the social structure and breeding system of the species. Although investment is typically male-biased, high competition between females can lead to a reversed pattern of female- biased investment. As among males, scent marking and counter-marking are often used to advertise territory defence and high social rank. Female odours have been implicated in the reproductive suppression of young or subordinate females across a range of social systems, with females of lower competitive ability potentially benefiting by delaying reproduction until conditions are more favourable. Further, the ability to recognise individuals, group members and kin through scent underpins group cohesion and cooperation in many social species, as well as playing an important role in mother-offspring recognition. However, despite the diversity of female scent signals, chemical communication in female mammals remains relatively understudied and poorly understood. We highlight several key areas of future research that are worthy of further investigation.

Abstract
OBJECTIVE To evaluate the hydroethanolic extract toxicity, obtained from Tropaeolum majus L. (TM) on mouse testicular tissue. METHOD In this experimental study, we used 32 male NMRI mice. The experimental groups received 75, 375 and 750 mg/kg of TM extract, respectively. Twenty-four hours after the last experimental day, serum samples were collected for hormonal measurement. Then, the cauda of epididymis and testis were removed for sperm count and histopathological assessments. RESULTS Testosterone serum and testicular levels decreased in 750 mg/kg in the treated group when compared to the control animals (1.65±0.25; p=0.041 and 98.83±8.67; p=0.034 respectively). Histopathological criteria such as epithelial vacuolization (9.3±1.1; p=0.034), sloughing (4.3±0.4; p=0.027) and detachment (12.2±0.9; p=0.031) of germ cells were significantly increased in 750 mg/kg in the treated mice. In addition, there were no significant changes in histopathological criteria; sperm head numbers, Johnsen's scoring, and morphometry assessments were carried out in the 75 and 375 mg/kg treated mice. At the dose of 750 mg/kg, the seminiferous tubule diameter (193.2±4.6; p=0.019), seminiferous epithelium height (139.2±5.1; p=0.023), and maturation arrest were significantly decreased in this group. CONCLUSION In conclusion, TM extract has toxic effects on the mouse testicular tissue in high doses. Hence, we recommend caution concerning its consumption by patients with reproductive problems.

Abstract
Spermatogenesis requires intricate interactions between the germline and somatic cells. Within a given cross section of a seminiferous tubule, multiple germ and somatic cell types co-occur. This cellular heterogeneity has made it difficult to profile distinct cell types at different stages of development. To address this challenge, we collected single-cell RNA sequencing data from ∼35,000 cells from the adult mouse testis and identified all known germ and somatic cells, as well as two unexpected somatic cell types. Our analysis revealed a continuous developmental trajectory of germ cells from spermatogonia to spermatids and identified candidate transcriptional regulators at several transition points during differentiation. Focused analyses delineated four subtypes of spermatogonia and nine subtypes of Sertoli cells; the latter linked to histologically defined developmental stages over the seminiferous epithelial cycle. Overall, this high-resolution cellular atlas represents a community resource and foundation of knowledge to study germ cell development and in vivo gametogenesis.

Abstract
Fine particle matter (PM) is correlated with male reproductive dysfunction in animals and humans, but the underlying mechanisms remain unknown. To investigate the toxic mechanism of PM, 32 male Sprague-Dawley (SD) rats were exposed to saline or PM2.5 with the doses of 1.8, 5.4, and 16.2 mg/kg.b.w. via intratracheal instillation, respectively, one time every 3 days, in total times for 30 days. Sperm concentration, hormone level, the expressions of BTB-associated protein and the mitogen-activated protein kinase (MAPK) pathway, tumor necrosis factor α and transforming growth factor β3 levels were detected. The results showed a decrease in sperm number, testosterone and luteinizing hormone levels and altered ultrastructure of BTB in testis of rat after exposure to PM2.5 . The protein levels of N-Cadherin, Occludin, Claudin-11, and Connexin-43 were significantly decreased in the testes. TGF-β3 content in testes showed increase, with the p-p38/p38 MAPK ratio also increasing after PM2.5 exposure. These results demonstrate that PM2.5 restrained the expressions of BTB-associated proteins through activating TGF-β3/p38 MAPK pathway and decreasing testosterone secretion, and therefore lead to the damage of BTB resulting in the decrease of sperm quality, which might be the potential reasons for its negative effects on spermatogenesis and male reproduction.

Abstract
BACKGROUND Testicular function is modified by maturational gonadostatic control highly susceptible to negative physiologic niche-altering factors like UV-rays. OBJECTIVE This study was performed in order to uncover new aspects of Compact Florescent Lamps (CFLs) induced damages on the testicular tissue of rats and evaluating the effect of curcumin on testis of rats after exposure to compact florescent Lamps. MATERIALS AND METHODS Twenty-four adult male Albino rats were randomly divided into three groups: control group (ethyl oleate 0.2 ml, IP, for 45 days, without CFLs exposure), fluorescent group (ethyl oleate 0.2 ml, IP, daily and treated with 12 hr CFLs exposure for 45 days) and curcumin group (curcumin 20 µ M, IP along with 12 hr CFLs exposure for 45 days). The rats were anesthetized at the end of the experiment. Gonadotropin hormones and prolactin levels were measured; Histopathological and histomorphometrical analysis of the testis was carried out. RESULTS Results of this study showed that CFLs significantly decreased serum levels of follicle stimulating hormone, prolactin, testicular weight, sperm motility, TDI, and SPI. Furthermore, CFLs had no effect on serum levels of luteinizing hormone and sperm count and also, increased abnormal sperm shapes. Our results also showed that curcumin supplementation following CFLs reversed these alterations. CONCLUSION These results strongly suggest that CFLs severely impairs testis while curcumin as an antioxidant had protective effects on undesirable effects in testis induced by CFLs.

Abstract
In this review, we summarize recent findings on the effect of the anti-androgen flutamide on cell-cell junctions in the male reproductive system. We outline developmental aspects of flutamide action on the testis, epididymis, and prostate, and describe changes in junction protein expression and organization of junctional complexes in the adult boar following prenatal and postnatal exposure. We also discuss findings on the mechanisms by which flutamide induces alterations in cell-cell junctions in reproductive tissues of adult males, with special emphasis on cytoplasmic effects. Based on the results from in vivo and in vitro studies in the rat, we propose that flutamide affects the expression of junction proteins and junction complex structure not only by inhibiting androgen receptor activity, but equally important by modulating protein kinase-dependent signaling in testicular cells. Additionally, results from studies on prostate cancer cell lines point to a role for the cellular molecular outfit in response to flutamide.

Abstract
OBJECTIVES To assess the efficacy and safety of combination therapy with clomiphene citrate (CC) and anastrozole (AZ) for male hypoandrogenism. PATIENTS AND METHODS We identified patients treated with a combination of CC + AZ in the period 2014 to 2017. Data were gathered on patient characteristics and laboratory values at baseline. Total testosterone, bioavailable testosterone, oestradiol and testosterone:oestradiol ratio were measured before combination therapy (treatment with CC only) and at CC + AZ combination therapy follow-ups. Treatment side effects were recorded; prostatic-specific antigen and haematocrit levels were measured to assess safety after 6 months. As a secondary outcome, semen characteristics were compared at baseline and after at least 3 months of combination therapy when these data were available. Data were analysed using a paired t-test and Wilcoxon's signed-rank test. RESULTS A total of 51 men were included, with a mean age of 35.4 ± 7.4 years and a mean body mass index of 35.0 ± 8.0 kg/m2 . After CC treatment, total testosterone, bioavailable testosterone, and oestradiol levels all significantly increased. AZ was added in all patients with hyperoestrogenaemia (oestradiol >50 pg/mL) or a testosterone:oestradiol ratio <10. CC + AZ therapy maintained therapeutic total testosterone and bioavailable testosterone levels while also normalizing oestradiol levels and testosterone:oestradiol ratio. Eleven patients experienced side effects: anxiety/irritability, n = 5; decreased libido, n = 4; elevated (>54%) haematocrit, n = 2. CONCLUSION Combination therapy with CC + AZ is an effective and safe alternative for patients with elevated oestradiol level or low testosterone:oestradiol ratio.

Abstract
This study was conducted to explore the effects of maternal exposure to perfluorooctanoic acid (PFOA) on reproduction and development of male offspring mice. Pregnant mice were given 1, 2.5 or 5 mg/kg BW PFOA daily by gavage during gestation. The results showed that the survival number of offspring mice at weaning was significantly decreased. There were no differences in the testicular index of offspring mice between PFOA exposure groups and non-PFOA group. Maternal exposure to PFOA reduced the level of testosterone in the male offspring mice on PND 21 (p < 0.01) but increased in 1 mg/kg group and decreased in 2.5 and 5 mg/kg groups on PND 70 (p < 0.01). There were different degrees of damage to testis in a dose-dependent manner, and the number of Leydig cells markedly decreased (p < 0.01) in 2.5 and 5 mg/kg PFOA groups on PND 21 and PND 70. The expression of Dlk1-Dio3 imprinted gene cluster showed a decreasing trend, where Glt2, Rian and Dio3 gene expressions were significantly reduced (p < 0.05) on PND 21. Therefore, PFOA exposure during pregnancy reduces the number of survival offspring mice, damages testis, disrupts reproductive hormones and reduces the mRNA expressions of the Dlk1-Dio3 imprinted cluster in testis.

Abstract
Animal models and human studies showed that in utero cigarette smoke exposure decreases sperm counts of offspring. This study used a mouse model to investigate the effects of maternal exposure to cigarette smoke on reproductive systems in F1 and F2 male offspring. Female ICR mice were exposed either to clean air or to cigarette smoke during pregnancy at the post-implantation stage. Epididymal sperm counts were decreased in a cigarette smoke dose-dependent manner in F1 (by 40-60%) and F2 males (by 23-40%) at postnatal day 56. In F1, the seminiferous epithelium heights were lower in the cigarette smoke-exposed groups than in the control group, and these effects were sustained in F2 males. Results suggest that maternal cigarette smoke exposure during pregnancy can have a multigenerational adverse effect on sperm counts in male offspring, which is mediated through in utero exposure of fetal germ cells to cigarette smoke.

Abstract
Macrophages are innate immune cells present in essentially every organ of the body with dedicated tissue specific functions. We will present in this review the unique properties and functions of macrophage populations residing in the testis, an immune-privileged organ. Testicular macrophages (tMΦ) could be seen as guardians of fertility due to their immunosuppressive functions protecting spermatogenesis from auto immune-attack. They exhibit testis specific functions with essential roles in normal testis homeostasis and fetal testicular development. Recently, two distinct testicular macrophage populations have been characterized based on different localization, morphology, gene expression profiles, developmental origin and postnatal development. We will discuss the importance of these two testicular macrophage populations for organ specific functions such as testosterone production and spermatogenesis, as well as their role in establishing immuno-privilege highlighting the contributions of macrophages to male fertility.

Abstract
In this study, we aimed to investigate the protective effects of androgens, using letrozole (LET; an aromatase inhibitor), grape seed extract (GSE; a naturally occurring aromatase inhibitor and antioxidant), and testosterone propionate (Tp), against methotrexate (MTX)-induced testicular toxicity in adult male rats. MTX has been shown to induce oxidative stress and exhibit antiproliferative effects in the testes. Adult male rats received oral saline gavage (control group with no treatment), the potential protective agents (LET, GSE, or Tp) alone, MTX alone, or a combination of one of the potential protective agents and MTX. The testicular levels of oxidative stress markers and cytokines (tumor necrosis factor-α and interleukin-1β) were measured. Spermatogenesis and sperm viability were microscopically evaluated. Administration of LET and GSE 7 days before MTX improved spermatogenesis and sperm viability, as well as reduced the levels of oxidative stress markers and cellular cytokines. Exogenous testosterone exhibited anti-inflammatory and antioxidant activities, similar to GSE and LET. We also showed that enhancing the endogenous androgenic activity by LET and GSE protected spermatogenesis against MTX-induced testicular toxicity via reduction of inflammation and oxidative stress in the testes. Our data suggest that testosterone protected spermatogenesis owing to its antioxidant and anti-inflammatory properties.

Abstract
Prostate cancer (PCa) is one of the most common male malignancies in the world. It was aimed to investigate differential expression of inflammatory and related factors in benign prostatic hyperplasia (BPH), prostate cancer (PCa), histological prostatitis (HP) and explore the role of Inducible nitric oxide synthase (iNOS), (VEGF) Vascular endothelial growth factor, androgen receptor (AR) and IL-2, IL-8 and TNF-α in the occurrence and development of prostate cancer. RT-PCR was used to detect the mRNA expression level of iNOS, VEGF, AR and IL-2, IL-8 and TNF-α in BPH, PCa and BPH+HP. Western blotting and immunohistochemical staining were used to detect the protein levels of various proteins in three diseases. The results showed the mRNA and protein levels of iNOS, VEGF and IL-2, IL-8 and TNF-α were significantly increased in PCa and BPH+HP groups compared with BPH group (p < .05), while the AR was significantly lower than those in PCa and BPH+HP groups (p < .05). There was no significant difference in the mRNA and protein levels of iNOS, VEGF, AR and IL-2, IL-8 and TNF-α between PCa and BPH+HP groups (p > .05). iNOS, VEGF, AR and IL-2, IL-8 and TNF-α are involved in the malignant transformation of prostate tissue and play an important role in the development and progression of Prostate cancer (PCa).

BACKGROUND Varicocele is present in 10-20% of the male infertile population. PURPOSE Present study was done to demonstrate the reinforcing effect of berberine (BBR), as an antioxidant and anti-inflammatory agent, on Sertoli cells-related niche and spermatogonial stem cells (SSCs) self-renewal in experimentally-induced VCL condition. STUDY DESIGN 50 mature male Wistar rats were divided into control, control-sham, non-treated VCL-induced, 50 mg kg-1 and 100 mg kg-1 BBR-treated VCL-induced groups. METHODS The Leydig and Sertoli cells distribution and Leydig cells steroidogenic activity, expression of glial cell line-derived neurotrophic factor (GDNF), proto-oncogene Rearranged during Transfection (c-RET) receptor, Ets variant gene 5 (Etv5) and B-cell chronic lymphocytic leukemia (CLL)/lymphoma 6, member B (Bcl-6b) at mRNA and protein levels were analyzed. The mRNA integrity and DNA fragmentation were assessed. Finally, the serum levels of testosterone, inhibin B and testicular total antioxidant capacity, total thiol molecules, catalase, and malondialdehyde were evaluated. RESULTS Observations revealed that, the BBR significantly enhanced VCL-reduced Leydig and Sertoli cells population, maintained Leydig-Sertoli cells network, enhanced GDNF, c-RET Etv5 and Bcl6b expression, up-regulated testicular antioxidant and endocrine status. CONCLUSION The BBR by boosting Leydig-Sertoli cells network up-regulates the GDNF, Etv5 and Bcl-6b expression/synthesis in SSCs, which in turn improves SSCs self-renewal activities. Thus, the BBR could be considered as an appropriate agent for antioxidant therapy of VCLs. However, more studies with bigger sample number and focus on BBR-induced effects on other genes involving in the self-renewal process are needed to have more deterministic results.

Abstract
The insulin family of growth factors (insulin, IGF1, and IGF2) are critical in sex determination, adrenal differentiation, and testicular function. Notably, the IGF system has been reported to mediate the proliferation of steroidogenic cells. However, the precise role and contribution of the membrane receptors mediating those effects, namely, insulin receptor (INSR) and type-I insulin-like growth factor receptor (IGF1R), have not, to our knowledge, been investigated. We show here that specific deletion of both Insr and Igf1r in steroidogenic cells in mice leads to severe alterations of adrenocortical and testicular development. Double-mutant mice display drastic size reduction of both adrenocortex and testes, with impaired corticosterone, testosterone, and sperm production. Detailed developmental analysis of the testes revealed that fetal Leydig cell (LC) function is normal, but there is a failure of adult LC maturation and steroidogenic function associated with accumulation of progenitor LCs (PLCs). Cell-lineage tracing revealed PLC enrichment is secondary to Insr and Igf1r deletion in differentiated adult LCs, suggesting a feedback mechanism between cells at different steps of differentiation. Taken together, these data reveal the cell-autonomous and nonautonomous roles of the IGF system for proper development and maintenance of steroidogenic lineages.-Neirijnck, Y., Calvel, P., Kilcoyne, K.

Abstract
Adult stem cells reside in specialized microenvironments, called niches, that maintain stem cells in an undifferentiated and self-renewing state. Defining and understanding the mechanisms that restrict niche signaling exclusively to stem cells is crucial to determine how stem cells undergo self-renewal while their progeny, often located just one cell diameter away from the niche, differentiate. Despite extensive studies on the signaling pathways that operate within stem cells and their niches, how this segregation occurs remains elusive. Here we review recent progress on the characterization of niche-stem cell interactions, with a focus on emerging mechanisms that spatially restrict niche signaling. Mol. Reprod.

Abstract
The reprogramming of fibroblasts to induced pluripotent stem cells raises the possibility that a somatic cell can be reprogrammed to an alternative, differentiated fate without first becoming a stem/progenitor cell. Recent work has shown that fibroblasts can be reprogrammed to other, terminally differentiated cells with a combination of several transcription factors. Here, we report that a combination of four developmental transcription factors; GATA4, SF-1, NGFI-B, and COUP TF2; efficiently reprogrammed human foreskin fibroblasts into functional induced Leydig-like cells (iLCs). The iLCs expressed Leydig-specific markers and secreted testosterone in vitro. We found that GATA4 and SF-1 were particularly critical for Leydig-specific markers expression and that GATA4, SF-1, and NGFI-B were necessary to generate functional iLCs that secreted testosterone. These findings demonstrate that fibroblasts can be directly converted into iLCs with a few, defined factors and may provide insight into potential therapies to treat testosterone deficiency.

Abstract
Male broiler breeders (n = 32) of 55 weeks of age were administered four different doses of capsulated d-aspartate (DA; 0, 100, 200 or 300 mg kg−1 day−1, p.o. (DA0, DA100, DA200 and DA300 respectively)) for 12 successive weeks to assess reproductive performance, blood testosterone, testicular histology and transcript levels of steroidogenic acute regulatory protein (StAR), cholesterol side-chain cleavage enzyme (P450scc), androgen receptor (AR), LH receptor (LHR), 3β-hydroxysteroid dehydrogenase (3BHSD), proliferating cell nuclear antigen (PCNA), glutamate ionotropic receptor NMDA type subunit 1 (GRIN1) and glutamate ionotropic receptor NMDA type subunit 2B (GRIN2B). Blood samples and ejaculates were collected, and bodyweight was recorded weekly for 10 weeks. AI was performed weekly for the last 2 weeks to determine the number of sperm penetration holes in the perivitelline layer, fertility and hatchability. Testes histology and transcript levels were evaluated in the 12th week. Bodyweight, numbers of Leydig cells and blood vessels, testis index and levels of sperm abnormalities were not affected (P > 0.05) by the treatment. However, sperm total and forward motility, plasma membrane integrity and functionality of sperm, ejaculate volume, testosterone concentration and fertility were higher (P < 0.05) in both the DA200 and DA300 groups compared with the other groups. In the DA100 and DA200 groups, sperm concentration, number of spermatogonia, thickness of the seminiferous epithelium and the diameter of tubules were significantly higher (P < 0.05) than the other DA-treated groups. The number of penetration holes, hatchability and malondialdehyde concentration were higher in the DA200, all DA-treated and DA300 groups respectively compared with the control and other treatment groups. Except for P450scc, AR, LHR and PCNA transcript levels in the DA300 groups, the relative expression of the genes evaluated improved significantly in the other DA-treated groups. Based on these experimental findings, it is concluded that DA improves reproductive performance of aged roosters.

Abstract
Androgen and its receptor (AR) play an important role in maintaining spermatogenesis and male fertility. The nonclassical androgen signaling pathway is proposed to be mediated by an AR in plasma membrane in Sertoli cells. Our previous studies showed that testosterone induces cytoplasmic AR translocation to plasma membrane by binding with caveolin-1. This study was conducted to the underlying molecular mechanism mediating AR trafficking. Data from mass spectrometry using membrane coimmunoprecipitation sample by anti-AR antibody indicated VAPA is a candidate protein. Knockdown of VAPA by shRNA decreased the amount of AR localized to membrane and nuclear fraction and prevented AR trafficking after being exposed to testosterone. Further studies indicated AR trafficking in Sertoli cells might be mediated by VAPA via association with vesicle transport protein OSBP. This study can enrich the mechanism of the androgen actions and will be helpful for further clarifying the nonclassical signaling pathway of androgens in Sertoli cells.

Abstract
The blood-testis barrier is a unique ultrastructure in the mammalian testis, located near the basement membrane of the seminiferous tubule that segregates the seminiferous epithelium into the basal and the adluminal (apical) compartment. Besides restricting paracellular and transcellular passage of biomolecules (e.g., paracrine factors, hormones), water, electrolytes, and other substances including toxicants and/or drugs to enter the adluminal compartment of the epithelium, the BTB is an important ultrastructure that supports spermatogenesis. As such, a sensitive and reliable assay to monitor its integrity in vivo is helpful for studying testis biology. This assay is based on the ability of an intact BTB to exclude the diffusion of a small molecule such as sulfo-NHS-LC-biotin (C20H29N4NaO9S2, Mr. 556.59, a water-soluble and membrane-impermeable biotinylation reagent) from the basal to the apical compartment of the seminiferous epithelium. Herein, we summarize the detailed procedures on performing the assay and to obtain semiquantitative data to assess the extent of BTB damage when compared to positive controls, such as treatment of rats with cadmium chloride (CdCl2) which is known to compromise the BTB integrity.

Abstract
Spermiation (sperm release) is the culmination of a spermatid’s journey in the seminiferous epithelium. After a long association with the Sertoli cell, spermatids have to finally ‘let go’ of the support from Sertoli cells in order to be transported to the epididymis. Spermiation is a multistep process characterised by removal of excess spermatid cytoplasm, recycling of junctional adhesion molecules by endocytosis, extensive cytoskeletal remodelling and final spermatid disengagement. Successful execution of all these events requires coordinated regulation by endocrine and paracrine factors. This review focuses on the endocrine regulation of spermiation. With the aim of delineating how hormones control the various aspects of spermiation, this review provides an analysis of recent advances in research on the hormonal control of molecules associated with the spermiation machinery. Because spermiation is one of the most sensitive phases of spermatogenesis to variations in hormone levels, understanding their molecular control is imperative to advance our knowledge of the nuances of spermatogenesis and male fertility.

Abstract
BACKGROUND Gonadal injury following chemotherapy is of increasing importance with the continuous improvement of survival rates. The protection of gonadotropin hormone antagonist (GnRHant) in long-term adult survivors of adolescent cancers and some autoimmune diseases has not yet been evaluated. METHODS The present study was aimed at longitudinally exploring whether the GnRHant could alleviate testicular damage induced by cyclophosphamide (CPA) in a rat model. Pubertal male rats were assigned to receive CPA with and without GnRHant. CPA was administrated at a single dose (100 mg/kg). GnRHant was started one hour prior to CPA injection and continued for four weeks (0.1 mg/kg, 3 times a week). Body and testes weights, testicular hormones, histological changes, and expression of androgen receptor (AR) in the testis were analyzed when rats matured into adulthood and completed a round of spermatogenesis. RESULTS Our results showed that body weight, histological injury, and AR expression in the testis were improved in the GnRHant + CPA group. However, testes weight and testicular hormones (anti-Müllerian hormone, inhibin B, and testosterone) did not markedly change. CONCLUSION Our results indicate that the GnRHant administration before and after CPA in pubertal rats can protect long-term testicular injury induced by CPA via increased AR expression in the testes.

Abstract
This study investigated the possible mechanisms of antispermatogenic action of Dalbergia sissoo in Parkes male mice. Mice were orally administered aqueous leaf extract of Dalbergia sissoo (50 and 100 mg kg-1 body weight day-1 for 35 days) and various testicular indices such 3β- and 17β-hydroxysteroid dehydrogenase (HSD) activities, Western blot analyses of StAR, cytochrome P450scc and caspase-3, germ cell apoptosis by TUNEL, and lipid peroxidation and antioxidant enzymes activities were assessed. A significant increase in lipid peroxidation level and a marked decrease in activities of superoxide dismutase, catalase, 3β- and 17β-HSD were noted in the testis of Dalbergia-treated mice compared to controls. The treatment also had adverse effect on expression levels of StAR and cytochrome P450scc in the testis. There was an increase in the number of TUNEL-positive germ cells and in expression level of caspase-3 in testes of Dalbergia-treated mice, especially in those treated with 100 mg dose compared to controls. By 56 days of withdrawal therapy, the alterations induced in the above parameters recovered to control levels. Our results thus suggest that Dalbergia treatment interferes with steroidogenesis and produces oxidative stress in the testis, which may induce germ cell apoptosis leading to suppression of spermatogenesis.
