Int J Reprod Biomed 2024; 22:383-394. [PMID: 39091425 PMCID: PMC11290194 DOI: 10.18502/ijrm.v22i5.16439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 01/09/2024] [Accepted: 01/24/2024] [Indexed: 08/04/2024] Open
Abstract
Background Helicobacter pylori (H. pylori) causes sterility by affecting the reproductive system. Vitamin B12 improves sperm quantity and function. Objective Vitamin B12 protection against H. pylori adverse effects was investigated. Materials and Methods 40 C57 male mice (6 wk) were randomly assigned to 4 equal groups (n = 10) including, group 1 (control without any intervention), group 2 (H), 3 (HP), and 4 (HB) received 1 × 109 colony forming unit (CFU) of H. pylori, 1 × 109 CFU of H. pylori+phosphate buffered saline, 1 × 109 CFU of H. pylori+50 μ g/kg vitamin B 12 intraperitoneally, respectively. In the induction groups, the H. pylori was orogasterically injected 3 times with 1 cc phosphate buffered saline throughout the day. Then testicular metrics, sperm motility, viability, quantity, and shape, plasma levels of malondialdehyde (MDA), superoxide dismutase, glutathione peroxidase, and total antioxidant capacity were measured. Also, testicular-tissue changes were examined using Johnson scores, tubular differentiation index, and spermatogenesis index. Vitamin B12, homocysteine, and testosterone serum levels were examined. Results The results showed a significantly lower Johnson score, tubular differentiation index, and spermatogenesis index, and serum level of testosterone and homocysteine as well as a higher MDA level in the H and HP groups than the HB group (p < 0.05). In contrast, the highest superoxide dismutase and glutathione peroxidase enzymes activity and total antioxidant capacity as well as the lowest serum level of MDA were found in the HB group compared to other groups (p < 0.05). Conclusion Vitamin B 12 increased antioxidant enzyme activity, enhanced sperm parameters, and decreased injury to testicular tissue. It can be used as a potent antioxidant in reducing testicular damage induced by H. pylori.

Abstract
The escalation of technological advancements, coupled with the increased use of hazardous chemicals, has emerged as a significant concern for human health. Exposure to environmental pollutants like heavy metals and pesticides (insecticides, herbicides and fungicides) is known to significantly contribute to various health problems, particularly affecting reproductive health. Disturbances in reproductive potential and reproductive toxicity in males are particularly worrisome. Existing literature suggests that exposure to these environmental pollutants significantly alters male reproductive parameters. Thus, it is imperative to thoroughly analyze, comprehend, and evaluate their impact on male reproductive toxicity. Oxidative stress and disruptions in redox equilibrium are major factors through which these pollutants induce changes in sperm parameters and affect the reproductive system. Insecticides, fungicides, and herbicides act as endocrine disruptors, interfering with the secretion and function of reproductive hormones such as testosterone and luteinizing hormone (LH), consequently impacting spermatogenesis. Additionally, heavy metals are reported to bio-accumulate in reproductive organs, acting as endocrine disruptors and triggering oxidative stress. The co-operative association of these pollutants can lead to severe damage. In this comprehensive review, we have conducted an in-depth analysis of the impact of these environmental pollutants on the male reproductive system, shedding light on the underlying mechanisms of action.

CHEMOSPHERE 2023; 340:139896. [PMID: 37604338 DOI: 10.1016/j.chemosphere.2023.139896] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 08/09/2023] [Accepted: 08/18/2023] [Indexed: 08/23/2023]
Abstract
Lead (Pb) is an emerging contaminant widely distributed in aquatic environments, which has serious effects on human and animal health. In this study, we determined whether Pb exposure affects gametogenesis, sex steroids, estrogen (ERα and ERβ), and androgen (AR) receptors. Adult specimens of Astyanax bimaculatus were exposed in duplicate to 15, 50, and 100 μg/L of lead acetate, whereas the control group was not exposed. After 28 days of exposure, fish were euthanized and samples of the gonads, liver, and blood were collected for analysis. The results indicated a reduction in the gonadosomatic index as well as the diameters of the vitellogenic follicles and seminiferous tubules in the exposed groups. Morphometry of gametogenesis revealed inhibition of the secondary oocyte growth and a reduction in the number of spermatozoa in the 50 and 100 μg/L Pb-treated groups. In females, plasma 17β-estradiol (E2) increased following 15 and 50 μg/L Pb treatment, whereas males exhibited an increase in E2 and 11-ketotestosterone following treatment with 15 and 100 μg/L Pb, respectively. Vitellogenin was significantly reduced in females exposed to 100 μg/L Pb, but metallothionein levels were unchanged. ERα, ERβ, and AR were immunolocalized in the somatic and germ cells, with increased ovarian expression of ERα and Erβ in the 100 μg/L Pb-treated group, but no significant difference in AR among the groups. In males, only ERα increased in the 100 μg/L Pb-treated group. These results indicate that Pb exposure impairs gametogenesis, disrupts estrogen receptor signaling, and affects the expression of major reproductive biomarkers in A. bimaculatus.

Effectiveness of Withania frutescens root extract on testicular damage induced by lead acetate in adult albino rats. Reprod Toxicol 2023; 115:102-110. [PMID: 36535557 DOI: 10.1016/j.reprotox.2022.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 12/11/2022] [Accepted: 12/14/2022] [Indexed: 12/23/2022]
Abstract
Withania frutescens was used previously in traditherapy against poisoning, gastric ulceration, and dysentery treatments. Because no previous studies reporting on its therapeutic effects on male reproductive system and fertility disorders, this study aims to examine its effect on lead induced testicular damages as well as sperm count and hormonal status in rats. The present study is performed to determine their phytochemical compositions using GC-MS analysis, their antioxidant and anti-inflammatory activities in-vitro using spectrophotometry and then to estimate testosterone levels, sperm count, histopathological features, as well as spermatogenesis (TDI) and spermiogenesis (SPI) indices. The experiment is conducted for three months using four groups (Group A: control rats; Group B: exposed rats to lead-acetate; Group C: exposed rats to lead-acetate and 200 mg/kg of W. frutescens extract; Group D: treated rats with 200 mg/kg of W. frutescens extract). The obtained results show a total of 10 identified components from GC-MS analysis. Whereas a total phenolic content of 63.23 ± 3.82 GAE/g of extract, 25.16 ± 1.21 µg/mL of anti-free radical activity, and reducing power of 163.19 ± 6.01 µg/mL. A high anti-inflammatory activity is determined by hemolysis inhibition (IC50 =12.71 ± 1.06 µg/mL) and protein denaturation inhibition (IC50 =6.8 ± 1.23 µg/mL). Besides, lead exposure causes histological alterations in testis and decreases serum testosterone level, sperm count, and TDI and SPI indices. W. frutescens treated and co-treated animals showed no toxic effects throughout the experiment. However, it is found to improve testosterone level, increase sperm count, attenuate the testicular histopathological effect of lead, and increase TDI and SPI. These findings . these findings suggest that W. frutescens is a better source of bioactive compounds, which play an effective role against lead testicular damages. Furthermore, this natural extract can be utilized potentially in pharmaceutical and medicinal applications.

Abstract
The current study investigates the potential alleviating activity of bulbs (B) and leaves (L) of Allium triquetrum aqueous extract (ATE) on repro-toxicity induced by lead acetate (Pb) in male Wistar rats administrated orally for 3 consecutive weeks. Eighteen groups of rats were divided into the control, Pb (500 mg/kg body weight/day), positive controls of B and L (2 g, 3 g, 4 g, 6 g/kg body weight/day), in addition to four mixtures of each of Pb-B (Pb-B1, Pb-B2, Pb-B3, Pb-B4) and Pb-L (Pb-L1, Pb-L2, Pb-L3, Pb-L4). The two extracts were subjected to phytochemical screening and HPLC analysis. Sperm characteristics were evaluated by CASA system, as well as the serum testosterone, testicular and epididymal levels of glutathione (GSH), glutathione peroxidase (GPx), and malondialdehyde (MDA). The phytochemical screening proved that bulbs' and leaves' extracts were rich in various compounds and the HPLC showed that leaves contain more tannins. Results revealed a significant decrease in the testicular and in the epididymal weights, sperm concentration, motility, testosterone, velocity, vitality, round cells, GSH, and GPx levels in the Pb-intoxicated rats compared to the control, with the exception of MDA concentration that was significantly increased. However, the co-administration of garlic extracts (Pb-B and Pb-L) exhibited a significant increase in all mentioned markers, except for the MDA level which was reduced. Likewise, Pb caused histological injuries in the testicular seminiferous of rats, while the co-administration of wild garlic has reduced such effect, especially in the higher doses. Both extracts of Pb-B and Pb-L have attenuated Pb toxicity in a dose-dependent manner. In conclusion, aqueous extracts of A. triquetrum have the potential to reduce Pb testicular injuries by boosting sperm characteristics and ameliorating oxidative stress markers.

Abstract
Lead (Pb), a widespread heavy metal, may induce serious diseases, particularly male reproductive injury. However, the mechanisms by which Pb induces testicular injury remain unclear. In this paper, we established a mouse model of Pb-induced testicular injury via an intraperitoneal injection of lead chloride at a concentration of 1.5 mg/kg body weight. We confirmed that Pb could induce a series of injuries, including a low litter size, smaller testes, more weak offspring, direct injury, and aberrant spermiogenesis. Our study demonstrated that Pb could inhibit lysine acetylation (Kac) and succinylation (Ksuc) via western blot (WB) and immunofluorescence (IF) analyses. We subsequently separated different germ cells that contained Pre-meiotic spermatogonia (SPG), meiotic spermatocyte (SPC), and round spermatid (RS) into the Pb-treated and control groups and verified that Pb inhibited Kac in SPC, RS, and particularly, during meiosis. Furthermore, our results regarding the inhibition of pyruvate kinase and mitochondrial electron transport chain complex I and II in the Pb-treated groups suggested that Pb may restrain key enzymes to block the TCA cycle and that the low TCA cycle activity could reduce the contents of two important metabolites, acetyl-CoA and succinyl-CoA, to inhibit Kac and Ksuc. Moreover, we examined the influences of the inhibition of Kac and Ksuc on spermiogenesis, which indicated that decreased Kac and Ksuc could impede the replacement of transition proteins in elongating sperm and disorder the distribution of germ cells in the seminiferous tubule. Our research provides novel insights into the mechanisms of Pb reproductive toxicity with respect to lysine acetylation and succinylation.
