Abstract
Diabetes mellitus induces testicular damage, increases sperm abnormalities, and impairs reproductive dysfunction due to induction of endocrine disturbance and testicular oxidative stress. This study evaluated the reproductive protective effect of ellagic acid (EA) against testicular damage and abnormalities in sperm parameters in Streptozotocin (STZ)-induced diabetic rats (T1DM) and examined some possible mechanisms of protection. Adult male rats were segregated into 5 groups (n = 12 rat/each) as control, control + EA (50 mg/kg/day), T1DM, T1DM + EA, and T1DM + EA + brusatol (an Nrf-2 inhibitor) (2 mg/twice/week). All treatments were conducted for 12 weeks, daily. EA preserved the structure of the seminiferous tubules, prevented the reduction in sperm count, motility, and viability, reduced sperm abnormalities, and downregulated testicular levels of cleaved caspase-3 and Bax in diabetic rats. In the control and diabetic rats, EA significantly increased the circulatory levels of testosterone, reduced serum levels of FSH and LH, and upregulated Bcl-2 and all steroidogenic genes (StAr, 3β-HSD1, and 11β-HSD1). Besides, it reduced levels of ROS and MDA but increased levels of GSH and MnSOD and the transactivation of Nrf2. All these biochemical alterations induced by EA were associated with increased activity and nuclear accumulation of Nrf2. However, all these effects afforded by EA were weakened in the presence of brusatol. In conclusion, EA could be an effective therapy to alleviated DM-induced reproductive toxicity and dysfunction in rats by a potent antioxidant potential mediated by the upregulation of Nrf2.

Abstract
BACKGROUND Metformin has long been used for glycemic control in diabetic state. Recently, other benefits of metformin beyond blood glucose regulation have emerged. OBJECTIVES To investigate the effect of metformin on the expression of testicular steroidogenesis-related genes, spermatogenesis, and fertility of male diabetic rats. MATERIALS AND METHODS Eighteen adult male Sprague Dawley rats were divided into three groups, namely normal control (NC), diabetic control (DC), and metformin-treated (300 mg/kg body weight/day) diabetic rats (D+Met). Diabetes was induced using a single intraperitoneal injection of streptozotocin (60 mg/kg b.w.), followed by oral treatment with metformin for four weeks. RESULTS Diabetes decreased serum and intratesticular testosterone levels and increased serum but not intratesticular levels of luteinizing hormone. Sperm count, motility, viability, and normal morphology were decreased, while sperm nuclear DNA fragmentation was increased in DC group, relative to NC group. Testicular mRNA levels of androgen receptor, luteinizing hormone receptor, cytochrome P450 enzyme (CYP11A1), steroidogenic acute regulatory (StAR) protein, 3β-hydroxysteroid dehydrogenase (HSD), and 17β-HSD, as well as the level of StAR protein and activities of CYP11A1, 3β-HSD, and 17β-HSD, were decreased in DC group. Similarly, decreased activities of epididymal antioxidant enzymes and increased lipid peroxidation were observed in DC group. Consequently, decreased litter size, fetal weight, mating and fertility indices, and increased pre- and post-implantation losses were recorded in DC group. Following intervention with metformin, we observed increases in serum and intratesticular testosterone levels, Leydig cell count, improved sperm parameters, and decreased sperm nuclear DNA fragmentation. Furthermore, mRNA levels and activities of steroidogenesis-related enzymes were increased, with improved fertility outcome. DISCUSSION AND CONCLUSION Diabetes mellitus is associated with dysregulation of steroidogenesis, abnormal spermatogenesis, and fertility decline. Controlling hyperglycemia is therefore crucial in preserving male reproductive function. Metformin not only regulates blood glucose level, but also preserves male fertility in diabetic state.

Abstract
Diabetes, an unresolved metabolic disorder, and lead contamination are prevalent problems in contemporary society. Previously, we have reported that either diabetes or lead exposure resulted in reproductive toxicity in male Wistar rats. The aim of this study was to evaluate whether diabetic rats exposed to lead demonstrate a higher degree of reproductive toxicity when compared with lead-exposed control rats. Diabetes was induced by injecting a single dose of streptozotocin (50 mg per kg body weight). Control and diabetic rats were exposed to lead at a concentration of 819 mg L-1 (0.15% lead acetate) through drinking water for a period of 30 days and assessed for reproductive and oxidative end points. The relative weights of the testes, epididymis, seminal vesicles, and the prostate gland were significantly decreased in diabetic rats. Daily sperm production, epididymal sperm count, motile, viable and HOS-tail swelled sperms, serum testosterone levels and testicular 3β- and 17β-hydroxysteroid dehydrogenase activity levels were significantly decreased in diabetic rats. Significant reductions in testicular and epididymal antioxidant enzyme activity levels and glutathione levels were observed in diabetic rats with an elevation in the levels of superoxide anions, hydrogen peroxides, and lipid peroxidation. A significant reduction in the number of implantations associated with elevated pre- and post-implantation losses was observed in females mated with diabetic males. Mild histopathological malformations were observed in the testis of the diabetic rats. Similar reproductive and oxidative toxicities were observed in lead-exposed control rats. Furthermore, lead exposed diabetic rats showed additional deterioration in reproductive end points and a noteworthy elevation in oxidative toxicity, suggesting that treatment with lead exacerbates reproductive toxicity in streptozotocin-induced diabetic rats.

Abstract
Alcoholism and cigarette smoking are pervasive problems that have been implicated in human health. In this study, independent and combinative toxicities of alcohol and benzo(a)pyrene (BaP) were tested for reproductive toxicity in rats. Male Wistar rats were exposed to BaP (100 μg per kg body weight) on alternative days and alcohol (2 g per kg body weight per day) daily, either individually or in combination for 60 days. Exposure to BaP or alcohol significantly decreased the fertility index and reduced the number of implantations associated with elevated pre- and post-implantation losses. The relative weights of testes, epididymis, seminal vesicles, and prostate gland were significantly decreased in BaP or alcohol administered rats. Exposure to BaP or alcohol significantly decreased daily sperm production, sperm density, percentages of motile, viable, HOS-tail swelled sperm, testicular 3β- and 17β-hydroxysteroid dehydrogenase activity levels, mRNA levels of steroidogenic acute regulatory protein, and serum testosterone levels. Further, in silico studies revealed the binding of BaP at the hydrophobic tunnel of StAR protein. Additional studies disclosed stable interactions of BaP with the amide group of ASN150 and the hydroxyl group of THR263 by forming three hydrogen bonds. Our results also showed that treatment of rats with BaP or alcohol caused a marked increase in levels of superoxide anions, hydrogen peroxide, and lipid peroxidation in testis and epididymis. Conversely, glutathione levels and activity levels of superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase in testis as well as epididymis decreased significantly in the experimental rats. Under the same conditions, increased fragmented DNA levels were observed in sperm. The results of the present study indicate that exposure to BaP or alcohol adversely affected the male reproductive functions, which may be, at least in part, due to androgen deficiency and/or oxidative stress-related mechanisms. Consistently, the present results also showed higher reproductive toxicity upon exposure to combinations of BaP and alcohol than upon their individual treatments. Therefore, this combination was classified as additive and synergistic responses of BaP and alcohol.
