Abstract
Glucagon-like peptide-1 (GLP-1) is an incretin released into the gastrointestinal tract after food ingestion, and stimulates insulin secretion from the beta cells of the pancreatic islets. Incretins have recently been reported to have extrapancreatic actions, and they are anticipated to have potential efficacy for conditions such as male infertility as well as diabetes. However, the effects of incretins on male reproductive function remain unclear. In this study, GLP-1 receptor expression and the effects of GLP-1 on spermatogenesis-associated genes were investigated using mouse testes and testis-derived cultured cell lines. Glp1r mRNA and GLP-1 protein were expressed in mouse testes at levels comparable to or greater than those in positive control adipose tissue, and the liver and intestine, and also in a Sertoli cell line (TM4) and a Leydig cell line (MA-10) as well as the GC-1 spg and GC-2 spd (ts) germ cell lines. TM4 cells treated with the GLP-1 receptor agonist exenatide showed transiently and significantly upregulated Kitl, Pdgfa, and Glp1r mRNA expression. Furthermore, at 1 hr post-exenatide administration to male mice, Kitl and Glp1r mRNA expression levels were significantly increased, and Pdgfa mRNA expression level also showed a tendency toward increase. TM4 cells were treated with various cell-activating agents, and bucladesine elicited significantly increased Glp1r mRNA expression. We suggest that GLP-1 provides acute stimulation of Sertoli cells in the mouse testis and has a stimulatory effect on the expression of spermatogenesis-related genes.

Gene Expression Changes in the Ovary Mediate Non-Anovulatory Mechanisms of Contraception with Levonorgestrel. Arch Med Res 2023; 54:102892. [PMID: 37804815 DOI: 10.1016/j.arcmed.2023.102892] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 09/06/2023] [Accepted: 09/20/2023] [Indexed: 10/09/2023]
Abstract
BACKGROUND Emergency contraception with levonorgestrel (LNG) is a viable option to prevent unintended pregnancies. Although the efficacy of LNG as an anovulatory agent decreases as treatment approaches ovulation, it still provides some contraceptive benefits. AIM To better understand the contraceptive mechanisms of LNG in ovulatory subjects. METHODS We conducted a study on Wistar rats that received a single dose of LNG (0.01 or 0.05 mg/kg) on the morning of proestrus before ovulation and evaluated its effects on ovarian gene expression, ovulation, and implantation. RESULTS Our findings showed changes in the expression of genes involved in follicular development and oocyte quality. Pregnancy rates - as an indicator of ovulation - and embryo implantation were significantly lower than those in the control group. CONCLUSIONS This study suggests that LNG alters regulatory factors in the ovary that are essential for the development of competent fertilizable oocytes, highlighting the non-anovulatory mechanisms by which levonorgestrel may regulate fertility and suggesting that it could be a novel observation that contributes to the understanding of emergency contraception in humans.

Abstract
The main goal of the current report is to assess the protective impacts of chia seeds against obesity-induced ovarian dysfunctions with a trial to elucidate the mechanism of action. Forty rats were divided into 4 groups including lean untreated, lean consuming chia seeds, obese untreated, and rats consumed high-fat diet (HFD) mixed with ground chia seeds for 10 weeks. Anthropometric measures including visceral fat, peri-ovarian fat, ovarian weights, and duration of the estrous cycle were computed. Serum luteinizing (LH), follicular stimulating (FSH), progesterone, estradiol hormones, and tumor necrosis-α (TNF-α) were estimated. Ovarian histopathology and immunohistochemistry (CD31) were performed. Results showed that chia seeds clearly reduced obesity and induced alteration in anthropometric measures with a clear increase in LH and progesterone. Such seeds notably reversed histopathological alteration and reduced TNF-α, and CD31 induced by HFD. Conclusively, chia seeds have a potential protective role against obesity-induced ovarian dysfunction owing to their anti-inflammatory properties.

Abstract
Paternal epigenome regulates placental and fetal growth. However, the effect of paternal obesity on placenta and its subsequent effect on the fetus via sperm remains unknown. We previously discovered abnormal methylation of imprinted genes involved in placental and fetal development in the spermatozoa of obese rats. In the present study, elaborate epigenetic characterization of sperm, placenta, and fetus was performed. For 16 weeks, male rats were fed either control or a high-fat diet. Following mating studies, sperm, placenta, and fetal tissue were collected. Significant changes were observed in placental weights, morphology, and cell populations. Methylation status of imprinted genes-Igf2, Peg3, Cdkn1c, and Gnas in spermatozoa, correlated with their expression in the placenta and fetus. Placental DNA methylating enzymes and 5-methylCytosine levels increased. Furthermore, in spermatozoa, DNA methylation of a few genes involved in pathways associated with placental endocrine function-gonadotropin-releasing hormone, prolactin, estrogen, and vascular endothelial growth factor, correlated with their expression in placenta and fetus. Changes in histone-modifying enzymes were also observed in the placenta. Histone marks H3K4me3, H3K9me3, and H4ac were downregulated, while H3K27me3 and H3ac were upregulated in placentas derived from obese male rats. This study shows that obesity-related changes in sperm methylome translate into abnormal expression in the F1-placenta fathered by the obese male, presumably affecting placental and fetal development.

Abstract
The present study aimed to ascertain how leptin antagonist injection affected testis weights, testis morphology and testosterone levels in immature male Swiss mice. Animals were administered with anti-leptin antibody subcutaneously, with or without equine chorionic gonadotropin (eCG). Control animals were treated with non-immune serum. Blood and testis were collected. The Androgen profile was analyzed in serum and tissue homogenates, and testes were histologically examined. Compared to controls, mice treated with an anti-leptin antibody with or without gonadotropins had a significant (p<0.05) increase in testis weight. Testosterone concentrations in the testis were significantly (p<0.05) higher in mice administered with anti-leptin antibody compared to control, but testosterone concentrations in blood were not affected. The diameter of seminiferous tubules, the diameter of the lumen and the width of spermatogenic cells were significantly (p<0.05) higher in mice in treatment groups compared to controls. We conclude that anti-leptin antibody administration in immature male mice increased testosterone concentrations in the testis and improved testis histological characteristics.

Abstract
IntroductionCamellia oil (CO), a common edible oil in China, contains a variety of active ingredients. In this study, we explored the combining effect and optimal feeding time of CO and squalene on hyperlipemia-induced reproductive damage rats and probably provided supportive data for use of CO for health benefits.MethodsWe established the hyperlipidaemia-induced reproductive damage model, and then the successfully modeled rats were randomly classified into four groups including a model control (MC) group, a camellia oil (CO) group, a camellia oil + squalene (COS) group, and a sildenafil (SN) group, which were feeding with different subjects during days 30 and 60. The normal (NC) group was fed under the same conditions.ResultsOur results showed that compared with the MC group, the CO, COS, and SN groups could significantly decline the serum TG, TC and LDL-C levels, increase the serum testosterone levels, the sperm counts in epididymidis and organ coefficients of penises, and no pathological change in penis and testis at days 30 and 60. Compared with the pure CO, the mixture of CO and squalene could significantly enhance the effect of decreasing the concentrations of TG, TC, and LDL-C and increasing the serum testosterone level and sperm count of epididymal tail, and the results of day 30 were better than those of day 60.DiscussionCO and squalene have a combining effect on lowering blood lipid, improving the level of testosterone and the number of epididymal tail sperm, and promoting the recovery of erectile and sexual function on hyperlipidemia-induced reproductive damage rats on day 30.

Abstract
The aim of this study was to evaluate the impact of diabetes mellitus type 2 (DM2) on the male endocrine system of Zucker Diabetic Fatty (ZDF) rats. Sexually mature ZDF rats were divided to a lean (control) and obese group, and had diabetes confirmed by blood tests. For the in vivo experiment, fasting blood was collected to obtain blood plasma. In case of the in vitro experiments, testicular fragments were cultured for 24 h, and the culture medium was collected. The concentrations of testosterone (T), androstenedione (A4), dehydroepiandrosterone (DHEA-S), estradiol (E2), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were quantified in the blood plasma and the medium by the ELISA method, while cholesterol (CHOL) was assessed spectrophotometrically. A significant decline of T (36.31 %), A4 (25.11 %) and FSH (26.99 %) as well as a significant increase of CHOL and E2 (36.17 %) was observed in the blood plasma of obese ZDF rats in comparison to the control. Under in vitro conditions, a significant decrease of FSH (23.35 %) accompanied by an increase of E2 was observed in the obese group compared to the control. In the case of CHOL, LH, T, DHEA and A4 no significant differences were observed. Our results suggest that except for FSH and E2 all steroid biomolecules were synthetized normally by the testicular tissue, however a dramatic endocrine disturbance was observed at the system level. We may conclude that DM2 has negative effects on systemic hormone secretion and these alterations are more pronounced in combination with obesity.

High-fat diet aggravates prenatal low-dose DEHP exposure induced spermatogenesis disorder: Characterization of testicular metabolic patterns in mouse offspring. CHEMOSPHERE 2022; 298:134296.

Abstract
Di-(2-ethylhexyl) phthalate (DEHP) is a widely used plasticizer and has been identified as a male prenatal reproductive toxicant. A high fat diet (HFD) has also been suggested as another potential disruptor of male reproductive function. Despite this potential synergism between DEHP exposure and HFD, little is known about the concomitant effects of prenatal DEHP and a subsequent HFD exposure on male offspring reproductive injury. Here we established a mouse model of prenatal exposure to DEHP (0.2 mg/kg/day) to assess the testicular development and spermatogenesis in offspring subjected to obesogenic diet during the pubertal period. Gross phenotype, hormone profiles and the testicular metabolome were analyzed to determine the underlying mechanism. We found that prenatal exposure to low-dose DEHP resulted in decreased sperm density, decreased testosterone (T) levels, increased luteinizing hormone (LH) levels and testicular germ cell apoptosis. Furthermore, these injury phenotypes were aggravated by pubertal HFD treatment. Testicular riboflavin and biotin metabolites were enriched implying their roles in contributing HFD to exacerbate offspring spermatogenesis disorders due to prenatal low-dose DEHP exposure. Our findings suggest that pubertal HFD exacerbates reproductive dysfunction associated with prenatal exposure to low-dose DEHP in male adult offspring.

Sperm Dysfunction in the Testes and Epididymides due to Overweight and Obesity Is Not Caused by Oxidative Stress. Int J Endocrinol 2022; 2022:3734572.

Abstract
Obesity is a condition that has been linked to male infertility. The current hypothesis regarding the cause of infertility is that sperm are highly sensitive to reactive oxygen species (ROS) during spermatogenesis in the testes and transit through the epididymides, so the increase in ROS brought on by obesity could cause oxidative stress. The aim of this study was to evaluate whether the activity of the enzymes catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPX) is capable of counteracting oxidative stress in sperm. The male Wistar rat was used as an overweight and obesity model, and analysis of fertility in these groups was carried out including the control group. Serum testosterone levels were determined, and the scrotal fat, testes, and epididymides were extracted. The epididymides were separated ini0 3 principal parts (caput, corpus, and cauda) before evaluating sperm viability, sperm morphology, damage to desoxyribonucleic acid of the sperm, and ROS production. The protein content and specific activity of the three enzymes mentioned above were evaluated. Results showed a gain in body weight and scrotal fat in the overweight and obese groups with decreased parameters for serum testosterone levels and sperm viability and morphology. Fertility was not greatly affected and no DNA integrity damage was found, although ROS in the epididymal sperm increased markedly and Raman spectroscopy showed a disulfide bridge collapse associated with DNA. The specific activities of CAT and GPX increased in the overweight and obesity groups, but those of SOD did not change. The amounts of proteins in the testes and epididymides decreased. These findings confirm that overweight and obesity decrease concentrations of free testosterone and seem to decrease protein content, causing poor sperm quality. Implications. An increase in scrotal fat in these conditions fosters an increase of ROS, but the increase of GPX and CAT activity seems to avoid oxidative stress increase in the sperm without damaging your DNA.

Abstract
Over the past decades, obesity and infertility in men increased in parallel, and the association between both phenomena have been examined by several researchers. despite the fact that there is no agreement, obesity appears to affect the reproductive potential of men through various mechanisms, such as changes in the hypothalamic-pituitary-testicular (HPT) axis, spermatogenesis, sperm quality and/or alteration of sexual health. Leptin is a hormone produced by the adipose tissue, and its production elevates with increasing body fat. Many studies have supported the relationship between raised leptin production and reproductive function regulation. In fact, Leptin acts on the HPT axis in men at all levels. However, most obese men are insensitive to increased production of endogenous leptin and functional leptin resistance development. Recently, it has been recommended that Kisspeptin neurons mediate the leptin's effects on the reproductive system. Kisspeptin binding to its receptor on gonadotropin-releasing hormone (GnRH) neurons, activates the mammal's reproductive axis and stimulates GnRH release. Increasing infertility associated with obesity is probably mediated by the Kisspeptin-GnRH pathway. In this review, the link between obesity, kisspeptin, leptin, and male fertility will be discussed.

Abstract
The epididymis is an organ that performs all the biochemical changes responsible for sperm maturation. During ageing, histological alterations in the epididymis and decreased protein synthesis have been found. This might affect the sperm maturation process. The aim of this study was to determine if the changes in the epididymis during ageing might cause alterations in sperm maturation. Wistar rats of 3-4months old (young) and 18-21months old (old) were used. The testosterone concentration was determined and the epididymides were dissected and divided in three regions: caput, corpus, and cauda. The tissues were used for histological processing and sperm extraction. Testosterone concentration decreased 34% in the old animals compared to the young ones. The distribution of mannose, sialic acid, and N-acetylglucosamine in the glycocalyx of the sperm membrane of old animals was different from that of young animals. The same occurred with phosphatidylserine externalisation and protein phosphorylation at tyrosine residues. Epididymis histology in old animals showed tubular and cellular degeneration. Our results suggest that ageing affects maturational markers, likely due to alterations in the epididymis as a result of the testosterone decrease associated with ageing.

Role of peroxisome proliferator-activated receptor gamma (PPARγ) in the regulation of fatty acid metabolism related gene expressions in testis of men with impaired spermatogenesis. Reprod Biol 2021; 21:100543. [PMID: 34492575 DOI: 10.1016/j.repbio.2021.100543] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 07/13/2021] [Accepted: 08/06/2021] [Indexed: 12/26/2022]
Abstract
Although male infertility is a multifactorial syndrome in which genetic factors are responsible for up to 15 % of cases, there are few studies of genes involved in lipid metabolism and male infertility. Peroxisome proliferator-activated receptor gamma (PPARγ) is a ligand-activated transcription factor in testis tissue. PPARγ binds to DNA and regulates the genes for fatty acid (FA) metabolism. Thus, it has a key role in male reproduction. The current study assessed the expressions of fatty acid desaturase 2 (FADS2), elongation of very-long-chain fatty acids-like 2 (ELOVL2), stearoyl-CoA desaturase-1 (SCD), and lipoprotein lipase (LPL) and incorporation of PPARγ in the promoter regions of these genes in testicular tissue biopsies from 30 infertile males who underwent testicular sperm extraction. The samples were classified into three groups: obstructive azoospermia (OA), which was the positive control (n = 10); round spermatid maturation arrest (SMA, n = 10); and Sertoli cell-only syndrome (SCOS, n = 10). There were significantly lower relative mRNA expression levels of the FADS2, ELOVL2, SCD, and LPL genes in the SCOS (P < 0.01) and SMA (P < 0.01) groups compared to the OA control group. We observed a significant decrease in chromatin incorporation of PPARγ on the promoter regions of the candidate FA metabolism genes (P < 0.05). For the first time, the present study results show that PPARγ is a strong mediator for regulation of FA metabolism in human testis tissue and we confirmed its critical role in normal spermatogenesis.

Abstract
Obesity is a multifactorial condition with predominantly genetic and environmental causes and is an emerging risk factor for male infertility/subfertility. Epigenetic mechanisms are vulnerable to genetic and environmental changes. Our earlier studies have shown differential effects of genetically inherited (GIO) - and diet-induced- obesity (DIO) on DNA methylation in male germline. Contrary to DNA methylation is DNA demethylation, which also regulates the gene expression by activating transcription. The present study aimed to delineate the effects of obesity on the DNA demethylation pathway using two rat models: GIO (WNIN/Ob) and DIO (high-fat diet). We observed differential alterations in enzymes involved in DNA demethylation by oxidation (Tet1-3) pathway in testis in both groups. An increase in Tets in DIO group and a decrease in GIO group were noted. Analysis of oxidation pathway intermediates (5-hmC, 5-fC, and 5-caC) did not show any effect on testis in DIO group but an increase in 5-hmC and decrease in 5-caC levels in GIO group was observed. Analysis of transcript levels of enzymes related to deamination pathway in testis showed an increase (Gadd45a, Aicda, and Tdg) in DIO group and a decrease (Gadd45a, Aicda, and Tdg) in GIO group. Also, 5-hmC levels were differentially altered in the spermatozoa of both groups without any changes in Tet enzyme levels. These findings highlight differences in effects of GIO and DIO on DNA demethylation mechanisms in male germline, which could be due to differences in endocrine and metabolic profile as well as white fat distribution observed earlier in two groups.

Abstract
BACKGROUND Obesity resulted by imbalance between the intake of energy and energy consumption can lead to growth and metabolic disease development in people. Both in obese men and animal models, several studies indicate that obesity leads to male infertility. OBJECTIVE This review has discussed some mechanisms involved in obesity-induced male infertility. METHODS Online documents were searched through Science Direct, Pubmed, Scopus, and Google Scholar websites dating from 1959 to recognize studies on obesity, kisspeptin, leptin, and infertility. RESULTS Obesity induced elevated inflammatory cytokines and oxidative stress can affect male reproductive functions, including spermatogenesis disorders, reduced male fertility power and hormones involved in the hypothalamus-pituitary-gonadal axis. CONCLUSION There is significant evidence that obesity resulted in male infertility. Obesity has a negative effect on male reproductive function via several mechanisms such as inflammation and oxidative stress.

Abstract
BACKGROUND Paternal obesity has been associated with reduced live birth rates. It could lead to inheritance of metabolic disturbances to the offspring through epigenetic mechanisms. However, obesity is a multifactorial disorder with genetic or environmental causes. Earlier we had demonstrated differential effects of high-fat diet-induced obesity (DIO) and genetically inherited obesity (GIO) on metabolic, hormonal profile, male fertility, and spermatogenesis using two rat models. The present study aimed to understand the effect of DIO and GIO on DNA methylation in male germline, and its subsequent effects on the resorbed (post-implantation embryo loss) and normal embryos. First, we assessed the DNA methylation enzymatic machinery in the testis by Real-Time PCR, followed global DNA methylation levels in spermatozoa and testicular cells by ELISA and flow cytometry, respectively. Further, we performed Methylation Sequencing in spermatozoa for both the groups. Sequencing data in spermatozoa from both the groups were validated using Pyrosequencing. Expression of the differentially methylated genes was assessed in the resorbed and normal embryos sired by the DIO group using Real-Time PCR for functional validation. RESULTS We noted a significant decrease in Dnmt transcript and global DNA methylation levels in the DIO group and an increase in the GIO group. Sequencing analysis showed 16,966 and 9113 differentially methylated regions in the spermatozoa of the DIO and GIO groups, respectively. Upon pathway analysis, we observed genes enriched in pathways involved in embryo growth and development namely Wnt, Hedgehog, TGF-beta, and Notch in spermatozoa for both the groups, the methylation status of which partially correlated with the gene expression pattern in resorbed and normal embryos sired by the DIO group. CONCLUSION Our study reports the mechanism by which diet-induced and genetically inherited obesity causes differential effects on the DNA methylation in the male germline that could be due to a difference in the white adipose tissue accumulation. These differences could either lead to embryo loss or transmit obesity-related traits to the offspring in adult life.

Abstract
High-fat diets affect male reproduction and sexual function. Therefore, we evaluated the effects of prolonged resveratrol administration on the metabolic, sperm, and testicular parameters of rats fed a cafeteria diet. Male Wistar rats were divided at weaning into control (C, n = 20) and cafeteria (CAF, n = 16) groups. At 3 months, half of them were given daily supplementations of resveratrol (C-R, n = 10; CAF-R, n = 8) at a dosage of 30 mg kg-1 body mass for 2 months. Animals were killed at 5 months of age, and blood, spermatozoa, and testes were collected for further analysis. Data were analyzed by one-way ANOVA, and P < 0.05 was considered statistically significant. The CAF diet promoted hyperglycemia (P < 0.0001), and treatment with resveratrol reversed this condition (P < 0.0001). The CAF diet reduced sperm viability and motility, while resveratrol improved these parameters (P < 0.05). Regarding testicular morphology, the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group (P = 0.0007). Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group. However, the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group (P = 0.0024). Although it did not modify body mass, the consumption of a CAF diet promoted hyperglycemia, adverse testicular morphology remodeling, and abnormal sperm, which were attenuated by treatment with resveratrol, thus suggesting a protective effect of this antioxidant on spermatogenesis.

Abstract
Objective The objective of this study was to evaluate the effects of intake of Brazil nut extract (BN) or sodium selenite solution on reproductive parameters of male diabetic animals. Methods A total of 48 Wistar rats were distributed into six groups: diabetes (n = 8); diabetes and Brazil nut extract (n = 8); diabetes and sodium selenite (Na2SeO3) (n = 8); Brazil nut extract (n = 8); sodium selenite (n = 8) and control (n = 8). A single dose of streptozotocin (65 mg/kg) was injected intravenously to the rats to induce diabetes. BN or Na2SeO3 were administered by gavage for 56 days. Results The diabetes caused critical alterations on body mass gain, reproductive parameters and antioxidant capacity. Treatments with both BN or Na2SeO3 were able to increase significantly the glutathione peroxidase and the daily sperm production, both in diabetic (p < 0.01 and p < 0.05) and in healthy animals (p < 0.01 and p < 0.05). Conclusion The Brazil nut extract and sodium selenite were able to improve some reproductive parameters of diabetic rats. Moreover, we could infer that this effect is probably due to the natural selenium content of the BN.

Abstract
Soy isoflavones (SIF) are biologically active compounds of non-steroidal and phenolic properties that are richly present in soybeans, which can reduce the body weight and blood lipids of obese animals. Recently, SIF have been reported to affect reproductive ability in obese male rats. However, the specific mechanism has not been well defined. The aim of the current study was to study the possible mechanisms for the effect of SIF administration on obesity induced spermatogenic defects. Obese rats model induced by high-fat diets were established and gavage treated with 0, 50,150 or 450 mg of SIF/kg body weight/day for 4 weeks. Here, our research shows that obesity resulted in spermatogenic degeneration, imbalance of reproductive hormone, testicular oxidative stress and germ cell apoptosis, whereas evidently recovery effects were observed at 150 and 450 mg/kg SIF. We also have discovered that 150 and 450 mg/kg SIF can activate Nrf2/HO-1 pathway in control of Bcl-2, BAX and cleaved caspase-3 expression with implications in antioxidant protection. Our study indicates the potential mechanism of SIF regulating spermatogenic function in obese rats, and provides a scientific experimental basis for the regulation of biological function of obese male reproductive system by SIF.

Abstract
The aims of the present work were to study the effect of maternal overweight on both the count and quality of sperm of the offspring and to assess whether this maternal condition is able to alter testicular integrity and spermatogenic process. To this end, male offspring from rats fed a standard (OSD) or cafeteria (OCD) diet were used. Body and testis weight, length, preputial separation and ano-genital distance (AGD) were recorded and testes were removed at 60 days of age. In addition, the number of germ, Leydig and Sertoli cells, spermatogenesis and sperm integrity were examined. The OCD rats were divided into two groups: offspring from rats with 25% and≥35% of overweight (OCD25 and OCD35, respectively). Both OCD groups showed higher body and testis weight, higher length, and greater AGD than OSD rats. OCD25 also showed early preputial separation and OCD35 exhibited a high level of testosterone with normal glycemia. Both OCD25 and OCD35 rats had a lower number of spermatozoa and Leydig cells than OSD rats, and OCD35 also exhibited a lower number of spermatogonia and Sertoli cells than OSD rats. In addition, both OCD groups exhibited lower number of sperm cells with normal morphology and sperm motility, and OCD35 showed changes in both the seminiferous epithelium and spermatogenic process. These results suggest that maternal overweight severely affects the reproductive capacity of male offspring, likely leading to a subfertility condition and a premature reduction of the reproductive life span.

Abstract
This study investigated the effects of curcumin and capsaicin on testicular and hepatic oxidant–antioxidant status in rats fed a high-fat diet (HFD). Male Sprague–Dawley rats were divided into 5 groups (8 rats per group). The control group was fed a normal control diet (standard laboratory chow), the HFD group was fed HFD (60% of total calories from fat), the HFD+CUR group received HFD supplemented with curcumin (1.5 g curcumin/kg HFD), the HFD+CAP group was given HFD supplemented with capsaicin (0.15 g capsaicin/kg HFD), and the HFD+CUR+CAP group received HFD supplemented with curcumin and capsaicin for 16 weeks. Hepatic and testicular thiobarbituric acid reactive substances (TBARS), reactive oxygen species (ROS), glutathione (GSH) levels, glutathione transferase activity, and Cu-Zn superoxide dismutase, glutathione peroxidase, and catalase protein expression and enzyme activities were measured. Protein expression was determined by Western blotting. GSH levels and antioxidant enzyme activities were measured with colorimetric methods. HFD slightly increased hepatic and testicular oxidative stress parameters. GSH levels did not change between groups. TBARS and ROS levels were significantly reduced in the HFD+CUR+CAP group compared with the HFD group. Liver and testis antioxidant enzyme activities and expression increased significantly with combined capsaicin and curcumin treatment. Curcumin and capsaicin treatment attenuated testicular and hepatic oxidative stress and enhanced the antioxidant defense system. The combination of capsaicin and curcumin with HFD seems to have some remarkable and beneficial effects on testicular oxidative damage in the fatty liver rat model.

Abstract
Sperm counts have shown a progressive decline across the world since the mid-1900s. Global rates of obesity have been climbing at a similarly alarming rate, suggesting that these two factors may be linked. However, studies examining the relationship between body mass index (BMI) and male fertility have produced conflicting results. These discrepancies among studies are commonly attributed to limitations that are inherent in human studies such as correlational data and confounding factors-limitations that are absent from animal studies. Hence, we conducted a systematic review and meta-analysis of animal studies that experimentally induced obesity with a high-fat diet and measured impacts on sperm traits and/or male fertility. Overall, we found strong, consistent evidence in animal studies that high-fat diets are detrimental for male fertility. Compared with controls, males fed a high-fat diet had smaller testes and sex accessory glands relative to body size, reduced semen quality, reduced mating success, and reduced fertilization success. This is the first time that experimental data of high-fat diet effects on male reproduction have been synthesized in a meta-analysis, and thus, our results provide novel insight to the complex question of how dietary-induced obesity affects male fertility. The strong negative effects detected in animal models suggest that the inconsistent results plaguing human studies are an artefact of limitations inherent in correlational studies rather than a true effect.

Abstract
AIMS To explore the antidepressant- and anxiolytic-like effects of an aqueous extract of Turnera diffusa Willd (Turneraceae) and to explore its possible toxic side effects on behavior, target organ function, and spermatic quality. MATERIALS AND METHODS Acute effects of a T. diffusa aqueous extract were evaluated in adult male mice with the plus-maze, forced swimming and open field tests to identify the possible anxiolytic, antidepressant and stimulant effects of this extract. Effects of T. diffusa aqueous extract were further investigated through two approaches. a) Male and female adult mice receiving a 28-day treatment were evaluated in a neurobehavioral test battery; later, changes in their biochemical parameters and in target organ morphology were analyzed. b) In young adult (16-weeks old) and mature (46-weeks old) males, spermatic quality and testes morphology during a complete spermatogenesis cycle were analyzed after a 35-day treatment. RESULTS T. diffusa aqueous extract induced remarkable anxiolytic- and antidepressant-like effects without affecting locomotor activity. This extract did not elicit behavioral signs of neural side effects, a sex-dependent reduction in body weight gain was produced without affecting functional parameters or the morphology of target organs. The highest dose improved cellular turnover in the testes of mature mice. CONCLUSION T. diffusa aqueous extract induced a clear anxiolytic-like effect, and for the first time, we reported an antidepressant effect. Clinical potential or even intake of T. diffusa in the context of traditional medicine can be supported by its efficacy to positively modulate behavior and its safety for a wide range of doses.

Abstract
The nutritional transition that the western population has undergone is increasingly associated with chronic metabolic diseases. In this work, we evaluated a diet rich in saturated fatty acids (hyperlipidic, HL) after weaning of the offspring rats submitted to maternal protein restriction on the hepatic mitochondrial bioenergetics. Wistar rats were mated and during gestation and lactation, mothers received control diets (NP, normal protein content 17%) or low protein (LP, 8% protein). After weaning, rats received either NL (normolipidic) or HL (+59% SFA) diets up to 90 days of life. It was verified that all respiratory states of hepatic mitochondria showed a reduction in the LP group submitted to the post-weaning HL diet. This group also presented greater mitochondrial swelling compared to controls, potentiated after Ca2+ addition and prevented in the presence of EGTA (calcium chelator) and cyclosporin A (mitochondrial permeability transition pore inhibitor). There was also an increase in liver protein oxidation and lipid peroxidation and reduction in catalase and glutathione peroxidase activities in the LP group fed HL diet after weaning. Our data suggest that adult rats subjected to maternal protein restriction were more susceptible to hepatic mitochondrial damage caused by a diet rich in saturated fatty acids post-weaning.

Abstract
Semen quality and male fertility depend on numerous factors such as age, environment, lifestyle, physical activity, genetic background and occupation. We aimed to access the effect of aerobic exercise, low- and high-fat diet on mice testis tissue, and sperm function. Obese and nonobese male mice C57BL/6 were exposed to high fat (Hf) or low fat (Lf) and/or activity (Exe: exercise or Sed: sedentary). Finally, testicular morphometric characteristics, sperm concentration and motility (light microscopy), sperm morphology (eosin/nigrosin dye), lipid peroxidation (BODIPY C11 Probe), chromatin (acridine orange and chromomycin A3 staining) were compared within obese groups (Hf/Exe, Lf/Exe, Lf/Sed, Hf/Sed) and nonobese groups (Hf/Exe, Lf/Exe, Lf/Sed, Hf/Sed). Both exercise and diet interventions did not show any alteration in testicular morphological characteristics, sperm morphology and DNA fragmentation within both obese and nonobese groups (p > 0.05). Exercise and/or diet resulted in a significant increase in sperm concentration and motility within both groups (p < 0.05). Exercise in both groups leads to high percentage of lipid peroxidation (p < 0.05). Exercise intervention significantly improved sperm protamine deficiency within obese group (p < 0.05). We concluded that exercise intervention was more effective than diet in improvement of sperm function within obese groups.

Abstract
Obesity is a multifactorial disorder with predominantly genetic and/or environmental causes. Our aim was to delineate effects of genetically inherited and high-fat diet-induced obesity on fertility and spermatogenesis using two Wistar rat models: genetically inherited obese (GIO) WNIN/Ob rats and diet-induced obese (DIO) rats, which received a high-fat diet. The terminal body weights were similar in both groups, but there was a significant difference in metabolic and hormone profiles between the groups. Fertility assessment revealed a significant decrease in the litter size due to increased pre- and postimplantation loss in the DIO group, whereas the rats in the GIO group were infertile due to lack of libido. Significantly decreased sperm counts were observed in the GIO group compared with the DIO group. Enumeration of testicular cells on the basis of ploidy and cell type-specific expression markers, to study the effect of obesity on spermatogenesis, demonstrated that the GIO and DIO states affected mitosis: spermatogonia and S-phase population were increased. However, distinctive effects were observed on meiosis and spermiogenesis in both the groups. Differential effects of GIO and DIO on fertility and spermatogenesis could be due to the significant difference in white adipose tissue accumulation between the groups and not due to high body weights. The differential effects of obesity suggest male obesity-induced infertility observed in humans could be a combination of genetic and environmental factors.

Abstract
The effect of obesity on testicular activity in prepubertal and pubertal rats was investigated in the present study. Obesity was induced in adult females by feeding a high-calorie diet (HCD). These females were mated with normal males and were fed an HCD during pregnancy and lactation. The male offspring born to obese mothers and fed an HCD after weaning were found to be obese. Seminiferous tubules of offspring from control mothers (OCM) and offspring from HCD-fed mothers (OHCDM) had the same set of germ cells at different age intervals, namely spermatogonia, leptotene spermatocytes, zygotene spermatocytes, pachytene spermatocytes and round and elongated spermatids on postnatal days (PND) 7, 13, 17, 24 and 36, and on the day of preputial separation, respectively. However, there was a significant decrease in round and elongated spermatids and the epididymal sperm count, coupled with a significant decrease in testosterone and an increase in leptin serum concentrations in OHCDM compared with OCM. These results show that obesity in prepubertal rats does not affect the age-dependent appearance of germ cells according to developmental hierarchy, but it does interfere with spermatid formation, resulting in a reduced sperm count, which may be due to a deficiency of testosterone mediated by hyperleptinaemia.

Abstract
BACKGROUND Serum leptin levels are augmented in obese infertile men and in men with azoospermia. They also correlate inversely with sperm concentration, motility and normal forms. The mechanisms underlying the adverse effects of excess leptin on male reproductive function remain unclear. The present study aimed to evaluate the effects of exogenous leptin on sperm parameters in mice and to explore the underlying mechanisms. METHODS We treated normal adult male mice with saline, 0.1, 0.5 or 3 mg/kg leptin daily for 2 weeks. After treatment, serum leptin levels, serum testosterone levels, sperm parameters and testicular cell apoptosis were evaluated. Blood testis barrier integrity and the expression of tight junction-associated proteins in testes were also assessed. We further verified the direct effects of leptin on tight junction-associated proteins in Sertoli cells and the possible leptin signaling pathways involved in this process. RESULTS After treatment, there were no significant differences in body weights, reproductive organ weights, serum leptin levels and serum testosterone levels between leptin-treated mice and control mice. Administration of 3 mg/kg leptin reduced sperm concentration, motility and progressive motility while increasing the percentage of abnormal sperm and testicular cell apoptosis. Mice treated with 3 mg/kg leptin also had impaired blood testis barrier integrity, which was related to decreased tight junction-associated proteins in testes. Leptin directly reduced tight junction-associated proteins in Sertoli cells, JAK2/STAT, PI3K and ERK pathways were suggested to be involved in this process. CONCLUSIONS Exogenous leptin negatively affects sperm parameters and impairs blood testis barrier integrity in mice. Leptin reduced tight junction-associated proteins in Sertoli cells, indicating that leptin has a direct role in impairing blood testis barrier integrity. Given the function of blood testis barrier in maintaining normal spermatogenesis, leptin-induced blood testis barrier impairment may be one of the mechanisms contributing to male subfertility and infertility.

Abstract
In a similar manner to erectile dysfunction (ED), osteocalcin (OC) is also said to be associated with cardiovascular disease (CVD); however, the effect of OC in ED is unclear. This study was conducted based on the Fangchenggang Area Male Health and Examination Survey (FAMHES) project that ran between September and December 2009. ED was evaluated using the International Index of Erectile Function (IIEF-5). OC was shown to be associated with mild (unadjusted: OR = 0.647; P = 0.016) or moderate (unadjusted: OR = 0.453; P = 0.007) ED. Meanwhile, higher OC levels were more prominently associated with ED (unadjusted: OR = 0.702; P = 0.014). When subdividing the groups by age, the correlation between OC and ED presented in those aged 40–49 years, even in the multi-adjusted model, for those with moderate (OR = 0.255, P = 0.044) and severe (OR = 0.065, P = 0.005) ED. The relationship between OC and ED was also associated with a high level of testosterone, non-obesity, drinking, and non-metabolic syndrome. In summary, OC may play a protective role in middle-aged (40–49 years) men with moderate-severe ED, especially those with a high level of testosterone, non-obesity, drinking, and non-metabolic syndrome.

Ghosh S, Mukherjee S. Testicular germ cell apoptosis and sperm defects in mice upon long-term high fat diet feeding. J Cell Physiol 2018; 233:6896-6909. [PMID: 29665058 DOI: 10.1002/jcp.26581] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2017] [Accepted: 03/01/2018] [Indexed: 12/29/2022]
Abstract
The growing prevalence of male infertility is a matter of serious concern. One of the putative causes being nutritional excess from continuous consumption of high fat diet (HFD) leading to insulin resistance albeit the specific relationship is not fully understood. Besides, there are many contradictions in the available literature on the subject. Therefore, we sought to characterize in detail the effects of HFD upon testicular function and sperm quality in mice with particular focus on isolated testicular germ cells and spermatozoa, respectively. In this study, we treated 8-week old male Swiss albino mice with HFD for the duration of 5 months; control animals were reared on standard diet. We observed HFD induced progressive deterioration of testicular histoarchitecture leading to disruption of seminiferous tubules, increased vacuolization, and partial to complete tubular atrophy. Time dependent adverse effects on sperm count, motility, and morphology were noticed. Interestingly, numerous anomalies were detectable in sperm head and tail structures reflecting loss of reproductive capacity due to HFD. Maximal tissue and sperm damage was conspicuous at the endpoint, prompting us to examine oxidative stress markers. Enhanced intracellular reactive oxygen species (ROS) generation, augmentation of prooxidant activities, and compromised testicular antioxidant defences clearly implied conditions of oxidative stress in long-term HFD treated mice. This was concomitant with the onset of abnormally enhanced testicular germ cell apoptosis involving the mitochondrial intrinsic pathway. Thus, our findings revealed that ROS mediated deregulation of testicular germ cell apoptosis is critical in male reproductive impairment due to diet induced obesity.

Abstract
An interaction between obesity, impaired glucose metabolism and sperm function in adults has been observed but it is not known whether exposure to a diet high in fat during the peri-pubertal period can have longstanding programmed effects on reproductive function and gonadal structure. This study examined metabolic and reproductive function in obese rats programmed by exposure to a high fat (HF) diet during adolescence. The effect of physical training (Ex) in ameliorating this phenotype was also assessed. Thirty-day-old male Wistar rats were fed a HF diet (35% lard w/w) for 30 days then subsequently fed a normal fat diet (NF) for a 40-day recovery period. Control animals were fed a NF diet throughout life. At 70 days of life, animals started a low frequency moderate exercise training that lasted 30 days. Control animals remained sedentary (Se). At 100 days of life, biometric, metabolic and reproductive parameters were evaluated. Animals exposed to HF diet showed greater body weight, glucose intolerance, increased fat tissue deposition, reduced VO2max and reduced energy expenditure. Consumption of the HF diet led to an increase in the number of abnormal seminiferous tubule and a reduction in seminiferous epithelium height and seminiferous tubular diameter, which was reversed by moderate exercise. Compared with the NF-Se group, a high fat diet decreased the number of seminiferous tubules in stages VII-VIII and the NF-Ex group showed an increase in stages XI-XIII. HF-Se and NF-Ex animals showed a decreased number of spermatozoa in the cauda epididymis compared with animals from the NF-Se group. Animals exposed to both treatments (HF and Ex) were similar to all the other groups, thus these alterations induced by HF or Ex alone were partially prevented. Physical training reduced fat pad deposition and restored altered reproductive parameters. HF diet consumption during the peri-pubertal period induces long-term changes on metabolism and the reproductive system, but moderate and low frequency physical training is able to recover adipose tissue deposition and reproductive system alterations induced by high fat diet. This study highlights the importance of a balanced diet and continued physical activity during adolescence, with regard to metabolic and reproductive health.

Abstract
The obesity and its comorbidities, including resistance to leptin, impacts the reproductive function. Testes express leptin receptors in the germ cells and Leydig cells. Then, leptin-deficient animals are obese and infertile. We aimed to evaluate the structure and steroidogenic pathway of the testis of deficient leptin mice. Three months old male C57BL/6 mice (wild-type, WT) and deficient leptin (ob/ob) mice had their testes dissected and prepared for analyses. Compared to the WT group, the ob/ob group showed a greater body mass with smaller testes, and alterations in the germinative epithelium: fewer spermatogonia, spermatocytes, and spermatids. The Sertoli cells and the germ cells showed condensed nuclei and nuclear fragmentation indicating cell death, in agreement with a low expression of the proliferating cell nuclear antigen and a high expression of Caspase3. In the ob/ob group, the sperm was absent in the seminiferous tubules, and the steroidogenic pathway was compromised (low 3Beta hydroxysteroid dehydrogenase and steroidogenic acute regulatory protein). Further, all hormone receptors involved in the testicular function were down expressed (androgen, estrogen, follicle-stimulating, luteinizing, aromatase, and nicotinamide adenine dinucleotide phosphate). In conclusion, the findings indicate significant morphological, hormonal and enzymatic changes in the testis of the ob/ob mice. The shifts in the enzymatic steroidogenic pathway and the enzymes related to spermatic activity support the insights about the failures in the fertility of these animals. The study provides new evidence and contributes to the understanding of how the lack of leptin and obesity might negatively modulate the testicular function leading to infertility.

Abstract
Obesity has grown to pandemic proportions. It affects an increasing number of children, adolescents and young adults exposed to the silent comorbidities of this disorder for a longer period. Infertility has arisen as one important comorbidity associated with the energy dysfunction promoted by obesity. Spermatogenesis is a highly regulated process that is determined by specific energetic requirements. The reproductive potential of males relies on hormonal-dependent and -independent stimuli that control sperm quality. There are conflicting data concerning the impact of male overweight and obesity on sperm quality, as well as on the possible paternal-induced epigenetic trait inheritance of obesity. In addition, it remains a matter of debate whether massive weight loss induced by lifestyle interventions, drugs or bariatric surgery may or may not benefit obese men seeking fatherhood. Herein, we propose to discuss how energy balance may modulate hormonal signalling and sperm quality in overweight and obese men. We also discuss some molecular mechanisms that mediate obesity-related dysfunction in male reproductive system and how paternal obesity may lead to trait inheritance. Finally, we will discuss how lifestyle modifications and sustained weight loss, particularly the loss achieved by bariatric surgery, may revert some of the deleterious effects of obesity in men and their offspring.

A high-fat diet impairs reproduction by decreasing the IL1β level in mice treated at immature stage. Sci Rep 2017; 7:567.

Abstract
Obesity causes low-grade inflammation that is involved in male infertility. Interleukin 1 beta (IL1β) plays an important role in this process. A high-fat diet (HFD) is the most common cause of obesity. However, the effect of a HFD on IL1β and its consequence in reproduction remain unclear. We established a HFD model in mice treated at immature stage (mice-TIS) and mice treated at mature stage (mice-TMS). Surprisingly, we found that a HFD decreased IL1β levels and was accompanied by an increase in testosterone in mice-TIS, while the reverse results were observed in mice-TMS. In addition, a HFD caused a reduction in testis macrophages and in the expression of inflammasome-related genes and proteins in mice-TIS. Furthermore, we found that IL1β inhibited testosterone secretion through down-regulating the gene expression of P450SCC and P450c17. However, the influence on mice-TIS that were induced by a HFD was recovered by stopping the HFD. In this study, we are the first to report that a HFD impairs the reproductive system by decreasing IL1β and enhancing testosterone levels in mice-TIS, which are different from the effects in mice-TMS. This provides new ideas for the treatment of obesity-induced infertility.

Abstract
This study evaluated the impact of a high-fat diet (HFD) during different stages of rat life, associated or not with maternal obesity, on the content of sex steroid hormones and morphophysiology of Leydig cells. The following periods of development were examined: gestation (O1), gestation and lactation (O2), from weaning to adulthood (O3), from lactation to adulthood (O4), gestation to adulthood (O5), and after sexual maturation (O6). The HFD contained 20% unsaturated fat, whereas the control diet had 4% fat. Maternal obesity was induced by feeding HFD 15 weeks before mating. All HFD groups presented increased body weight, hyperinsulinemia and reduced insulin sensitivity. Except for O1, all HFD groups exhibited a higher adiposity index, hyperleptinemia, reduced testosterone and estradiol testicular levels, and decreased testicular 17β-HSD enzyme . Morphometrical analyses indicated atrophy of Leydig cells in the O2 group. Myelin vesicles were observed in the mitochondrial matrix of Leydig cells in O3, O4, O5 and O6, and autophagosomes containing mitochondria were found in O5 and O6. In conclusion, HFD feeding, before or after sexual maturation, reduces the functional capacity of rat Leydig cells. Maternal obesity associated with HFD during pregnancy/lactation prejudices Leydig cell steroidogenesis and induces its atrophy in adulthood, even if it is replaced by a conventional diet at later stages of life. Regardless of the life period of exposure to HFD, deregulation of leptin is the main factor related to steroidogenic impairment of Leydig cells, and, in groups exposed for longer periods (O3, O4, O5 and O6), this is worsened by structural damage and mitochondrial degeneration of these cells.

Abstract
Leptin is a protein secreted by the adipocytes, which serves as a link between fat and brain. Its main action is to decrease appetite and increase energy expenditure, but it is also involved in the control of different neuroendocrine systems, including gonadal axis. Although the effects of leptin deficiency on reproduction are well recognized, the effect of excess leptin on male reproductive function is not clear. The aim of this study was to evaluate fertility and sperm parameters of male rats exposed to exogenous leptin. A group of adult male rats received exogenous leptin intraperitoneally (30 μg/kg/day) for 42 days, and a control group received only the vehicle during the same period. After the treatment, animals were evaluated for sperm count, sperm motility, and fertility after intrauterine artificial insemination. There was no statistically significant difference between the groups related to sperm production, sperm concentration, and sperm motility. However, fertility evaluation after artificial insemination showed a quantitative decrease in the uterus plus fetuses weight, number of implantation sites, and number of live fetuses. The fertility potential showed a reduction of about 40%, whereas the preimplantation loss rate increased more than 2-fold in leptin-treated animals. In conclusion, leptin administration to nonobese male rats impairs ability of treated animals to generate offspring, since the occurrence of implantation was diminished. So leptin can impair sperm quality, affecting the reproductive capacity.

Abstract
Background: A high-fat diet (HFD) promotes the oxidative stress formation, which in turn has hazardous effects on reproductive system and fertility. The present study examines the potential positive effects of a restricted high-fat diet (RHFD) and antioxidants consumption on sperm parameters and testis tissue in rats. Methods: Male rats (n = 48) were divided into four groups (12 in each group): control group (Cont), HFD group, RHFD, and RHFD with astaxanthin and vitamins E and C group (RHFDA). After 12 weeks, serum analysis and sperm parameters study were performed. Sections of fixed testes were stained with Hematoxilin and Eosin to study the histological changes. A one-way ANOVA was used to compare the data. Results: HFD fed animals presented significant increase in weight load and serum low density lipoprotein (LDL-C) levels (P < 0.05). The sperm count in RHFD was lower than three other groups (P < 0.05) and sperm motility of RHFDA group was significantly higher than HFD and RHFD groups (P < 0.05). The histological study was showed a significant increase in spermatogonium number in RHFDA compared to three other groups (P < 0.05). The number of spermatocyte I and spermatid in RHFD was significantly (P < 0.05) lower than Cont and HFD groups. Conclusion: HFD and obesity can affect sperm parameters and spermatogenesis and antioxidants consumption may improve their quality. Although the RHFD is a benefit way in weight loss and decrease of LDL-C of serum, but it is suggested that is not effective on sperm quality improvement.

Materials and Methods: Male Wistar rats were divided into four groups: SC (standard chow), HF-S (high fat diet rich in saturated fatty acids), HF-P (high fat diet rich in polyunsaturated fatty acids), HF-SP (high fat diet rich in saturated and polyunsaturated fatty acids). The rats were fed for 16 weeks. Blood samples, testes and genital fat deposits were collected for analysis. Data were analyzed by one-way ANOVA and Bonferroni post hoc test, considering p<0.05 as statistically significant. Results: Different high-fat diets promoted an increase in the body mass (p<0.0001). The genital fat deposits were higher in the high-fat groups (HF-S, HF-P, HF-SP) (p=0.0004). Regarding serum parameters, the animals in the HF-S and HF-SP groups presented hyperglycemia (p=0.0060), hyperinsulinemia (p=0.0030) and hypercholesterolemia (p=0.0021). All of the hyperlipidemic groups showed hyperleptinemia (p=0.0019). Concerning the testis, the HF-S group showed a reduction on the seminiferous epithelium height (p=0.0003) and cell proliferation (p=0.0450). Seminiferous tubule diameter was lower in the HF-SP than in the SC group (p=0.0010). Conclusions: The high fat diet administration, independent of the lipid quality, promotes overweight. Diet rich in saturated fatty acids (lard) alters the carbohydrate metabolism and the testicular morphology with reductions of seminiferous epithelium height, seminiferous tubule diameter and cell proliferation which could be related to a disturbance of spermatogenesis.

Abstract
Testosterone is an androgenic steroid hormone, which plays an important role in the regulation of male reproduction and behaviors, as well as in the maintenance of insulin sensitivity. Several studies showed that testosterone exerted beneficial effects in brain function, including preventing neuronal cell death, balancing brain oxidative stress and antioxidant activity, improving synaptic plasticity and involving cognitive formation. Although previous studies showed that testosterone deficiency is positively correlated with cognitive impairment and insulin-resistant obesity, several studies demonstrated contradictory findings. Thus, this review comprehensively summarizes the current evidence from in vitro, in vivo and clinical studies of the relationship between testosterone deficiency and insulin-resistant obesity as well as the correlation between either insulin-resistant obesity or testosterone deficiency and cognitive impairment. Controversial reports and the mechanistic insights regarding the roles of testosterone in insulin-resistant obesity and cognitive function are also presented and discussed.

Abstract
Metabolic syndrome is characterized with abdominal obesity, insulin resistance, dyslipidemia and hepatic dysfunction. Glycogen synthase kinase-3β (GSK-3β) expression has been observed in adipose tissues in obese and diabetic humans, and in rodents. The aim of study was to investigate role of GSK-3β in modulation of metabolic alterations in alcoholic fed rats. Male Wistar albino rats (180-220 g) were used. High fat diet (HFD) for 8 weeks and alcohol (2%) from third to eighth week were given. Lithium chloride (LiCl), a GSK-3β inhibitor (60 mg/kg) was used orally from third to eighth week. HFD treatment caused significant (p < 0.05) increase in the percentage of body weight gain, BMI, Lee index, different fat pads, liver weights, serum glucose, leptin, triglyceride, LDL, VLDL, cholesterol, alanine transaminase, aspartate transaminase, tissue thio-barbituric acid reactive substances, nitrate/nitrite and significant decrease in food intake (g), serum HDL and tissue GSH in HFD control rats, as compared to normal control (NC). Administration of alcohol (2%) ad libitum potentiated the effect of normal and HFD, respectively, in NC and HFD control rats, respectively. Administration of LiCl produced significant amelioration in biochemical and pathological changes caused in the form of metabolic syndrome in HFD alone and HFD and alcohol-treated rats. The histological observations also showed similar findings in liver tissue. It may be concluded that inactivation of GSK-3β consequently leads to increased leptin and insulin sensitivity as evidenced by the reversal of alterations caused due to metabolic syndrome in rodents fed with HFD and mild alcohol.

Abstract
Exercise improves health but few data are available regarding benefits of exercise in offspring exposed to developmental programming. There is currently a worldwide epidemic of obesity. Obesity in pregnant women predisposes offspring to obesity. Maternal obesity has well documented effects on offspring reproduction. Few studies address ability of offspring exercise to reduce adverse outcomes. We observed increased oxidative stress and impaired sperm function in rat offspring of obese mothers. We hypothesized that regular offspring exercise reverses adverse effects of maternal obesity on offspring sperm quality and fertility. Female Wistar rats ate chow (C) or high-energy, obesogenic diet (MO) from weaning through lactation, bred at postnatal day (PND) 120, and ate their pregnancy diet until weaning. All offspring ate C diet from weaning. Five male offspring (different litters) ran on a wheel for 15 min, 5 times/week from PND 330 to 450 and were euthanized at PND 450. Average distance run per session was lower in MO offspring who had higher body weight, adiposity index, and gonadal fat and showed increases in testicular oxidative stress biomarkers. Sperm from MO offspring had reduced antioxidant enzyme activity, lower sperm quality, and fertility. Exercise in MO offspring decreased testicular oxidative stress, increased sperm antioxidant activity and sperm quality, and improved fertility. Exercise intervention has beneficial effects on adiposity index, gonadal fat, oxidative stress markers, sperm quality, and fertility. Thus regular physical exercise in male MO offspring recuperates key male reproductive functions even at advanced age: it's never too late.

Abstract
This study compares the impact of obesogenic environment (OE) in six different periods of development on sperm parameters and the testicular structure of adult rats and their correlations with sex steroid and metabolic scenario. Wistar rats were exposed to OE during gestation (O1), during gestation/lactation (O2), from weaning to adulthood (O3), from lactation to adulthood (O4), from gestation to sexual maturity (O5), and after sexual maturation (O6). OE was induced by a 20% fat diet, and control groups were fed a balanced diet (4% fat). Serum leptin levels and adiposity index indicate that all groups were obese, except for O1. Three progressive levels of impaired metabolic status were observed: O1 presented insulin resistance, O2 were insulin resistant and obese, and groups O3, O4, and O5 were insulin resistant, obese, and diabetic. These three levels of metabolic damage were proportional to the increase of leptin and decreased circulating testosterone. The impairment in the daily sperm production (DSP) paralleled these three levels of metabolic and hormonal damage being marginal in O1, increasing in O2, and being higher in groups O3, O4, O5, and O6. None of the OE periods affected the sperm transit time in the epididymis, and the lower sperm reserves were caused mainly by impaired DSP. In conclusion, OE during sexual maturation markedly reduces the DSP at adulthood in the rat. A severe reduction in the DSP also occurs in OE exposure during gestation/lactation but not in gestation, indicating that breast-feeding is a critical period for spermatogenic impairment under obesogenic conditions.

Abstract
BACKGROUND AND AIMS Maternal protein restriction during rat pregnancy and lactation is associated with alterations in reproductive function of female offspring including delayed onset of puberty, decreased fertility and premature reproductive aging. These alterations may be related to ovarian prepubertal development, distribution of follicle populations and their steroidogenic capacities. We undertook this study to evaluate the ovarian function of prepubertal female offspring exposed to maternal protein restriction during pregnancy and/or lactation. METHODS Adult female Wistar rats were fed a control (C-20% casein diet) or restricted isocaloric diet (R-10% casein) during pregnancy--first letter--and lactation--second letter, to form four groups, CC, RR, CR, RC. Ovaries were collected from 21-day-old female offspring. Preantral and antral follicles were quantified and mRNA expression of key genes involved in follicular development and steroidogenesis (gonadotropin receptors, StAR, P450scc and P450 aromatase) was evaluated. Serum gonadotropin levels were measured. RESULTS Significantly decreased numbers of preantral and antral follicles were observed in CR and RC ovaries compared with CC. LH levels were lower and FSH higher in CR pups. mRNA expression of LH receptor (LH-R) was decreased in RR in comparison with the other groups. CR and RC expressed higher StAR, RC increased and RR decreased P450scc, whereas RR and CR decreased aromatase expression in comparison with CC. CONCLUSIONS Maternal protein restriction influences prepubertal ovarian follicular number and steroidogenic function in the rat offspring, although RR and CR nutritional schemes have similar outcomes, the mechanisms affecting ovarian function are at different levels of the hypothalamic-pituitary-ovarian axis.

Abstract
Obesity has been considered a public health issue in many countries and is of increasing concern for authorities over the past 6 years. The Zucker rat is a good experimental model for obesity and diabetes studies due to its metabolic characteristics that are similar to those developed by humans. A total of 12 obese Zucker rats and their lean littermates were killed in pubertal and young adult phases for assessing organ weights (testis and epididymis), testicular histomorphometric and stereological analyses, daily sperm production, and transit time in the epididymis. Sperm integrity was also investigated in the adult animals using the Comet assay. Alterations in organ weights, seminiferous epithelium architecture, sperm production, and transit time were noticed in the pubertal fatty rats. The volume density of the lymphatic space was decreased in both the ages. Adult animals had a significant increase in the extent of damage found in sperm DNA. Our results show for the first time that leptin receptor deficiency compromises sperm production during puberty and that genetic obese Zucker rats have increased sperm DNA fragmentation.

Abstract
Male obesity may lead to declines in testosterone levels, reproductive hormonal profile, and semen quantity. To assess the effects of obesity on spermatogenesis, Sprague-Dawley rats fed a high-fat diet served as a model of induced obesity. The litter sizes for females mated to obese males were significantly lower as compared to females mated with normal-diet-fed controls. Their serum high-density lipoprotein, low-density lipoprotein, cholesterol, and estradiol levels increased in obese males, but testosterone and follicle-stimulating hormone levels decreased. Testicular morphology disruptions included Sertoli-cell atrophy, disrupted tight junctions, and mitochondrial degeneration in spermatogenic cells. To further investigate the molecular mechanisms leading to high-fat-diet-induced changes, we employed testicular proteomic analysis on rats fed both types of diet. Three spots were up-regulated in rats fed a high-fat diet whereas two others were downregulated. One of the upregulated spots was palmitoyl-protein thioesterase 1 (PPT1), a lipoprotein metabolizing related enzyme localized to Sertoli cells. In a Sertoli-cell line cultured in a high-fat supplemented medium, PPT1 abundance was accompanied by increases in the endocytic vesicle-associated protein, clathrin, and decreases in the tight junctional proteins, ZO-1 and occludin. In conclusion, declines in rat male fertility induced by a high-fat diet are associated with an altered testicular protein expression pattern as well as disruption of testicular Sertoli-cell and spermatogenic-cell morphology. PPT1 expression may provide a testicular marker of reduced fertility in obese males, as increases in its expression may be detrimental to Sertoli-cell function during spermatogenesis.
