Int Immunopharmacol 2024; 129:111566. [PMID: 38364740 DOI: 10.1016/j.intimp.2024.111566] [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: 10/18/2023] [Revised: 01/07/2024] [Accepted: 01/16/2024] [Indexed: 02/18/2024]
Abstract
Studies have identified Coenzyme Q10 (CoQ10) as a promising agent in improving idiopathic male infertility; however, its role in chemically or environmentally induced testicular dysfunction is not well-established. We investigated the potential of CoQ10 to attenuate methotrexate (MTX)-induced testicular damage and to identify molecular targets of CoQ10 effects. Wistar rats received a single intraperitoneal dose of 20 mg/kg MTX on the fifth day of the 10-day experimental protocol. 100 mg/kg CoQ10 was given orally daily for ten days, alone or combined with MTX. The testes of MTX-treated animals showed thickened tunica albuginea, distortion of seminiferous tubules with a marked reduction of germinal lining, a few primary spermatocytes with no spermatozoa, apoptotic cells, congested sub-capsular and interstitial blood vessels, and interstitial edema. Reduction of reproductive hormones and increased oxidative, inflammatory, and apoptotic biomarkers levels were also seen in the MTX-treated rats. CoQ10 + MTX-treated rats were protected against MTX-induced testicular histological changes and showed improvement in testosterone, luteinizing-, and follicle-stimulating hormone serum levels compared to the MTX group. The testes of the CoQ10 + MTX-treated rats showed reduced malondialdehyde, myloperoxidase, tumor necrosis factor -α, interleukin-6 and -1β and Bax: Bcl2 ratio and enhanced glutathione, and catalase compared to MTX alone. CoQ10 enhanced MTX-induced downregulation of Nrf2 and PPAR-γ signaling and modulated its downstream targets, the inducible nitric oxide synthase, NF-κB, Bax, and Bcl2. In conclusion, CoQ10 targeted the Nrf2-PPAR-γ signaling loop and its downstream pathways, mitigating MTX-induced oxidative stress-related damages and alleviating the testicular dysfunction MTX caused. Our data suggest Nrf2-PPAR-γ signaling as a potential therapeutic target in testicular toxicity, where oxidative stress, inflammation, and apoptosis trigger damage.

Abstract
Renal toxicity is one of the side effects of methotrexate (MTX). Therefore, this study explored the use of astaxanthin (AST), as a natural carotenoid, against MTX-induced nephrotoxicity emphasizing the changes in oxidative stress and the expression of nuclear factor erythroid 2-related factor 2/heme oxygenase 1 (Nrf2/HO-1). During the 10 days of the experiment, male Wistar rats in different groups received MTX (10 mg/kg) on days 6, 8, and 10 and three doses of AST (25, 50, and 75 mg/kg) during the entire course. Renal failure caused by MTX was observed in significant histopathological changes and a significant increase in serum levels of creatinine, urea, and uric acid (p < 0.05). Oxidative change induced by MTX injection was also observed by remarkably increasing the tissue level of malondialdehyde (MDA) and decreasing the activity of superoxide dismutase (SOD) and catalase (p < 0.001). AST decreases the adverse effects of MTX by upregulating the expression of Nrf2/HO-1 genes (p < 0.01) and decreasing the tissue level of MDA (p < 0.01). Also, AST significantly reduced the amount of creatinine, urea, and uric acid in the serum and improved the activity of SOD and catalase in the kidney tissue (p < 0.05). Thus, AST may protect the kidney against oxidative stress caused by MTX.

Selenium mitigates methotrexate-induced testicular injury: Insights from male NMRI mice model. Birth Defects Res 2024; 116:e2315.

Abstract
BACKGROUND AND AIM Chemotherapy, particularly with methotrexate (MTX), often elicits testicular toxicity, leading to impaired spermatogenesis and hormone imbalances. This study aimed to investigate the potential protective effects of selenium (Se) against MTX-induced testicular injury. MATERIALS AND METHODS Male mice were divided into control, MTX, Se, and MTX + Se groups. Histopathological examination involved the preparation of testicular tissue sections using the Johnsen's tubular biopsy score (JTBS) for spermatogenesis evaluation. Biochemical tests included the assessment of testosterone, malondialdehyde (MDA), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) levels. Real-time quantitative polymerase chain reaction (RT-qPCR) was employed to analyze the expression of caspase 3 (casp3), tumor protein 53 (p53), B-cell lymphoma 2 (Bcl2), and Bcl2-associated X protein (Bax) genes. Statistical analysis was performed using ANOVA and Tukey's tests (p < .05). RESULTS Histopathological analysis revealed significant testicular damage in the MTX group, with decreased spermatogenesis and Leydig cell count, while Se administration mitigated these effects, preserving the structural integrity of the reproductive epithelium. Biochemical analysis demonstrated that MTX led to elevated malondialdehyde (MDA) levels and reduced testosterone, LH, and FSH levels, suggesting oxidative stress and Leydig cell dysfunction. Gene expression analysis indicated that MTX upregulated proapoptotic genes (casp3, p53, and bax) while downregulating the antiapoptotic Bcl2 gene. In contrast, Se treatment reversed these trends, highlighting its potential antiapoptotic properties. CONCLUSION Our findings underscore the potential of Se as a therapeutic agent to mitigate the reproductive toxicity associated with MTX-induced testicular injury. Se exerts protective effects by regulating oxidative stress, preserving hormone balance, and modulating apoptotic pathways. These results suggest that Se supplementation could be a promising strategy to alleviate chemotherapy-induced testicular damage and preserve male fertility.

Abstract
Disrupted spermatogenesis and testicular injury are among the devastating outcomes of methotrexate. A major contributor to methotrexate-induced testiculopathy is oxidative damage which triggers apoptosis and altered autophagy responses. Eicosapentaenoic acid ethyl ester (EPA-E) is an antihyperlipidemic derivative of omega-3 fatty acids that exhibited affinity to peroxisome proliferator-activated receptor-γ (PPAR-γ) that possesses both antioxidant and autophagy modulating properties. This is an exploratory study aiming at assessing the effectiveness of EPA-E to alleviate testicular damage induced by methotrexate. The specific exploratory hypothesis of this experiment is: EPA-E administration for 1 week to methotrexate-treated rats reduces testicular damage compared to control rats. As a secondary outcome, we were interested in identifying the implicated mechanism that mediates the action of EPA-E. In adult male Wistar rats, testiculopathy was achieved by a single methotrexate injection (20 mg/kg, ip). Rats received vehicle, EPA-E (0.3 g/kg/day, po) alone or with selective PPAR-γ antagonist (bisphenol A diglycidyl ether, BADGE) at 30 mg/kg/day, ip for 1 week. EPA-E recuperated methotrexate-attenuated serum total testosterone while reduced testicular inflammation and oxidative stress, restoring superoxide dismutase (SOD) while reducing malondialdehyde (MDA) and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Methotrexate-induced testicular apoptosis (caspase-3 and p53) was suppressed upon EPA-E treatment. Besides, EPA-E curbed methotrexate-induced abnormal autophagy by downregulating LC3A/B and beclin-1. Interestingly, BADGE-coadministration reversed EPA-E beneficial actions. Collectively, our findings suggest PPAR-γ role in EPA-E-mediated mitigation of methotrexate-evoked testiculopathy via suppression of oxidative stress, apoptosis, as well as abnormal autophagy. Furthermore, EPA-E could be used as a preventive therapy for some testiculopathies mediated by oxidative stress.

Abstract
BACKGROUND Neural tube defects (NTDs) are one of the most severe congenital abnormalities characterized by failures of the neural tube to close during early embryogenesis. Maternal folate deficiency could impact the occurrence of NTDs, however, the mechanisms involved in the cause of NTDs are poorly defined. RESULTS Here, we report that histone H3 methyltransferase disruptor of telomeric silencing 1-like (DOT1L) expression was significantly downregulated, and low levels of H3K79me2 were found in the corresponding NTDs samples with their maternal serum folate under low levels. Using ChIP-seq assays, we found that a decrease of H3K79me2 downregulates the expression of Shh and Sufu in mouse embryonic stem cells (mESC) under folate deficiency. Interestingly, folate antagonist methotrexate treatment led to attenuation of H3K79me2 due to Dot1l, affecting Shh and Sufu genes regulation. Upon further analysis, we find that the genes Shh and Sufu are both downregulated in the brain tissues of mice and humans with NTDs. There was a positive correlation between the transcription levels of Shh, Sufu and the protein levels of DOT1L by Pearson correlation analysis. CONCLUSION Our results indicate that abnormal Shh and Sufu genes expression reduced by aberrant Dot1l-mediated H3K79me2 levels could be the cause of NTDs occurrence.

Abstract
The blood-testis barrier (BTB) is a selectively permeable membrane barrier formed by adjacent Sertoli cells (SCs) in the seminiferous tubules of the testes that develops intercellular junctional complexes to protect developing germ cells from external pressures. However, due to this inherent defense mechanism, the seminiferous tubule lumen can act as a pharmacological sanctuary site for latent viruses (e.g., Ebola, Zika) and cancers (e.g., leukemia). Therefore, it is critical to identify and evaluate BTB carrier-mediated drug delivery pathways to successfully treat these viruses and cancers. Many drugs are unable to effectively cross cell membranes without assistance from carrier proteins like transporters because they are large, polar, and often carry a charge at physiologic pH. SCs express transporters that selectively permit endogenous compounds, such as carnitine or nucleosides, across the BTB to support normal physiologic activity, although reproductive toxicants can also use these pathways, thereby circumventing the BTB. Certain xenobiotics, including select cancer therapeutics, antivirals, contraceptives, and environmental toxicants, are known to accumulate within the male genital tract and cause testicular toxicity; however, the transport pathways by which these compounds circumvent the BTB are largely unknown. Consequently, there is a need to identify the clinically relevant BTB transport pathways in in vitro and in vivo BTB models that recapitulate human pharmacokinetics and pharmacodynamics for these xenobiotics. This review summarizes the various in vitro and in vivo models of the BTB reported in the literature and highlights the strengths and weaknesses of certain models for drug disposition studies. SIGNIFICANCE STATEMENT: Drug disposition to the testes is influenced by the physical, physiological, and immunological components of the blood-testis barrier (BTB). But many compounds are known to cross the BTB by transporters, resulting in pharmacological and/or toxicological effects in the testes. Therefore, models that assess drug transport across the human BTB must adequately account for these confounding factors. This review identifies and discusses the benefits and limitations of various in vitro and in vivo BTB models for preclinical drug disposition studies.

Abstract
Edaravone (ED) is a neuroprotective drug with beneficial effects against several disorders due to its prominent antioxidant activity. However, its effect against methotrexate (MTX)-induced testicular damage was not previously investigated. Therefore, we aimed to investigate the ability of ED to prevent the oxidative stress, inflammation, and apoptosis induced by MTX on the rat testis and to examine whether ED administration modulated the Akt/p53 signaling and steroidogenesis process. Rats were allocated into; Normal, ED (20 mg/kg, PO, for 10 days), MTX (20 mg/kg, i.p., on the 5th day), and ED + MTX groups. The results showed that MTX group exhibited higher serum activities of ALT, AST, ALP, and LDH in addition to histopathological alterations in the rat testis, compared to normal group. Furthermore, MTX induced down-regulation of the steroidogenic genes; StAR, CYP11a1, and HSD17B3 and reduced FSH, LH, and testosterone levels. The MTX group also showed higher levels of MDA, NO, MPO, NF-kB, TNF-α, IL-6, IL-1β, Bax, and caspase 3, as well as, lower levels of GSH, GPx, SOD, IL-10, Bcl2 compared to normal rats, p < 0.05. In addition, MTX treatment resulted in increased p53 expression and decreased p-Akt expression. Remarkably, ED administration significantly prevented all the biochemical, genetic, and histological damage induced by MTX. Hence, ED treatment protected the rat testis from apoptosis, oxidative stress, inflammation, and impaired steroidogenesis induced by MTX. This novel protective effect was mediated by decreasing p53 while increasing p-Akt protein expression.

Abstract
Methotrexate (MXT) is a medication used for cancer and rheumatoid treatment with severe organs toxicity as a side effect. Paullinia cupana (Guarana) is a plant with pleiotropic functions used to overcome the side effects of some chemotherapeutic medications. Current study aimed to examine the possible protective effect of guarana against oxidative stress induced by a single dose of MTX in testis. Forty male mice were divided into 4 groups (8 weeks old; 30 g weight), 1st group is negative control. The 2nd group is positive intoxicated group, received a single dose of MTX intraperitoneally (IP; 20 mg/kg BW in saline) on day 7. The 3rd group received guarana seed extract orally (300 mg/kg BW daily) for 12 days. The protective group was given guarana seed extract orally for 1 week, then on day 7 injected with MTX, and continued with guarana for extra 5 days. Blood was taken for biochemical measurement (hormones, antioxidants, cytokines, and oxidative stress biomarkers). Testicular tissues were taken for gene quantification (qRT-PCR), testicular oxidative stress activity (malondialdehyde; MDA, and SOD) and comet assay (sperm DNA damage), and histopathological changes at the end of experimental design. MTX intoxication caused a decrease in testicular SOD, GSH, and catalase and an increase in serum and tissue levels of MDA. Biomarkers of oxidative stress were increased by MTX intoxication, and were ameliorated by guarana administration to MTX-intoxicated mice. Guarana prevented the increase in IL-1β and IL-6 levels compared to mice intoxicated with MTX alone. MTX upregulated the expression of caspase-3 and downregulated Bcl-2 expression using qRT-PCR analysis. These negative impacts of MTX were protected by guarana pre-administration. MTX decreased reproductive hormones and altered spermogram parameters (sperm concentration and motility, and percentage of live and dead sperms). In addition, the mRNA expression of steroidogenesis-associated genes, such cytochrome P450 cholesterol side-chain cleavage enzyme (P450scc), and 17β hydroxyl steroid dehydrogenase (17β-HSD) was downregulated in the MTX-treated group, all were prevented by guarana administration. The sperm DNA damage revealed by a comet assay was increased in MTX group and was reversed to control levels by guarana supplementation. Finally, testis histology of MTX-group showed marked spermatocytes vacuolization and a decrease in spermatogenesis. Guarana administration abrogated histopathological changes reported in the Leydig cells and testicular tissues. In conclusion, guarana has the potential as a supplement medication to antagonize testicular oxidative stress induced by methotrexate.

Abstract
Methotrexate (MTX) and azathioprine (AZA) are chemotherapeutic, immunosuppressive, cytotoxic drugs with reported adverse effects, including oxidative damage to testis. This study aims to evaluate the potential effect of grape seed extract (GSE; gervital) to prevent testicular damage caused by MTX and AZA. Male albino rats were separated into six groups: group I, normal control group; group II, GSE (150 mg/kg/day); group III, MTX (8 mg/kg/week); group IV, AZA (15 mg/kg/day); group V, GSE (150 mg/kg/day) + MTX (8 mg/kg/week); group VI, GSE (150 mg/kg/day) + AZA (15 mg/kg/day). All rats were sacrificed, blood samples were obtained for testosterone analysis, and testis was removed for histological and ultrastructural studies and oxidation measurements. A reduction in relative body and testis weight, along with a significant decrease in testosterone levels, was observed. Histopathological and ultrastructural alterations induced by MTX or AZA included reduced spermatozoa, sloughing, marked reduction of spermatogenic cells, and pyknosis of some nuclei. Significant oxidative stress manifested as reduced glutathione (GSH) levels and catalase (CAT) and superoxide dismutase (SOD) activities, as well as increased malondialdehyde (MDA) levels. GSE administration showed an ameliorative effect on testosterone levels and histopathological and ultrastructural changes. GSE treatment also suppressed the increases in MDA levels and the decreases in GSH levels and CAT and SOD activities. In conclusion, these findings confirm that GSE is an effective antioxidant that protects testis from histopathological and ultrastructural damage induced by MTX and AZA. Therefore, GSE is a promising candidate for future use to minimize and alleviate MTX and AZA risks.

Expression of BmDHFR is up-regulated to trigger an increase in the BH4/BH2 ratio when the de novo synthesis of BH4 is blocked in silkworm, Bombyx mori. Int J Biol Macromol 2023; 225:625-633. [PMID: 36402389 DOI: 10.1016/j.ijbiomac.2022.11.124] [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: 07/07/2022] [Revised: 11/05/2022] [Accepted: 11/12/2022] [Indexed: 11/18/2022]
Abstract
Tetrahydrobiopterin (BH4) is a vital coenzyme for several enzymes involved in diverse enzymatic reactions in animals. BH4 deficiency can lead to metabolic and neurological disorders due to dysfunction in its metabolism. Sepiapterin reductase (SPR) and dihydrofolate reductase (DHFR) are crucial enzymes in the BH4 de novo synthesis pathway and salvage pathway, respectively. Dihydrobiopterin (BH2) is an oxidized product of BH4 metabolism. The ratio of BH4/BH2 is a key indicator of the stability of BH4 levels. The de novo pathway of BH4 synthesis is well-defined; however, little is known about the mechanisms of the salvage pathway in insects. Herein, we used the natural BmSPR mutant silkworm (lem) as a resource material. Our results reveal that the BmDHFR expression and the BH4/BH2 ratio were remarkably higher in lem as compared to the wild-type silkworm. In BmN cells, knockdown of BmSpr showed increased BmDHFR expression, while the BH4/BH2 ratio decreased after BmDhfr knockdown by RNAi. Furthermore, simultaneous RNAi of BmSpr and BmDhfr showed a further decrease in the BH4/BH2 ratio. These manifest that the expression of BmDHFR is up-regulated to trigger an increase in the BH4/BH2 ratio when the de novo synthesis of BH4 is blocked in silkworm. Additionally, the knockdown of BmSpr in wild-type silkworms also showed an increased BmDHFR level and BH4/BH2 ratio. Taken together, when the silkworm BH4 de novo synthesis pathway is blocked, the salvage pathway is activated, and BmDHFR plays an important role in maintaining the metabolic balance of silkworm BH4. This study enriches our understanding of the molecular mechanism of the BH4 salvage pathway and lays a good foundation for further studies on BH4 using the silkworm as a model insect.

Abstract
Taurine, a sulfur-containing amino acid, has a wide range of biological effects, such as bile salt formation, osmotic regulation, oxidative stress inhibition, immunomodulation and neuromodulation. Taurine has been proved to be synthesized and abundant in male reproductive organs. Recently, accumulating data showed that taurine has a potential protective effect on reproductive function of male animals. In physiology, taurine can promote the endocrine function of the hypothalamus-pituitary-testis (HPT) axis, testicular tissue development, spermatogenesis and maturation, delay the aging of testicular structure and function, maintain the homeostasis of the testicular environment, and enhance sexual ability. In pathology, taurine supplement may be beneficial to alleviate pathological damage of male reproductive system, including oxidative damage of sperm preservation in vitro, testicular reperfusion injury and diabetes -induced reproductive complications. In addition, taurine acts as a protective agent against toxic damage to the male reproductive system by exogenous substances (e.g., therapeutic drugs, environmental pollutants, radiation). Related mechanisms include reduced oxidative stress, increased antioxidant capacity, inhibited inflammation and apoptosis, restored the secretory activity of the HPT axis, reduced chromosomal variation, enhanced sperm mitochondrial energy metabolism, cell membrane stabilization effect, etc. Therefore, this article reviewed the protective effect of taurine on male reproductive function and its detailed mechanism, in order to provide reference for further research and clinical application.

Impact of anthocyanin on genetic stability in mammary adenocarcinoma-induced mice treated with methotrexate. GENES & NUTRITION 2022; 17:6. [PMID: 35513806 PMCID: PMC9074366 DOI: 10.1186/s12263-022-00709-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 03/31/2022] [Indexed: 11/17/2022]
Abstract
Background Genetic instability leads to genome mutations, changes in nucleotide sequences, rearrangements, and gains or losses of part of the chromosomes. This instability can initiate and develop cancer. This study evaluated genomic stability in methotrexate and anthocyanin-treated mammary adenocarcinoma model. Seventy albino mice were divided into seven groups: negative control, anthocyanin, methotrexate, Ehrlich’s solid tumor; Ehrlich’s solid tumor and methotrexate; Ehrlich’s solid tumor and anthocyanin; and Ehrlich’s solid tumor, methotrexate, and anthocyanin groups. Results Tumor weight and size were evaluated. Serum arylesterase activity was low in all the induced tumors and those treated with anthocyanin, methotrexate, or both. Poly[adenosine diphosphate (ADP)-ribose] polymerase activity was high, and glutathione S-transferase activity was low in the tumors treated with anthocyanin, methotrexate, or both, compared with that of the untreated tumor. There was an increase in DNA damage in the mice with solid tumors and those injected with methotrexate or methotrexate and anthocyanin, compared with that in the untreated mice. Conclusions There was a decrease in genetic instability and DNA damage in the tumor-bearing mice treated with anthocyanin, with a concomitant increase in nuclear poly[adenosine diphosphate (ADP)-ribose] polymerase activity, compared with those of the untreated group. Anthocyanin exerted positive effects in the treatment of mammary adenocarcinoma.

Abstract
Background Methotrexate (MTX) is a commonly used chemotherapeutic drug that has adverse toxic effects on germ cells. Naringin (NG) is a natural flavanone glycoside, with different phytotherapeutic applications, and its possible protective effects against MTX-induced testicular tissue damage were investigated in this study. Methods Low and high doses of NG (40 and 80 mg/kg/day) were given for 10 days by intraperitoneal (i.p.) injection and MTX (20 mg/kg i.p.) was given at the 4th day of the experiment, with or without NG in rats. Results The obtained results showed that exposure to MTX increased malondialdehyde (MDA) levels and nitric oxide (NO) production compared with the control. In the meantime, MTX depleted catalse (CAT), superoxide dismutase (SOD), glutathione reductase (GR), glutathione peroxidase (GPx), and reduced glutathione (GSH) in the testicular tissue. Further, serum testosterone levels were significantly decreased in the MTX group. NG significantly counteracted the aforementioned effects of MTX; however, NG80 was more effective in restoring SOD, GR, MDA and NO. Interestingly, NG80 achieved a better improvement in the ultrastructural pattern of the testicular cells in MTX-exposed rats. Conclusion These results indicated, for the first time, that NG could be a potential candidate therapy against MTX-reprotoxic impacts.

Abstract
AIMS Di (2-ethylhexyl) phthalate (DEHP), as an environmental endocrine-disrupting chemical (EDC), can induce male reproductive injury. N6-methyladenosine (m6A) plays a vital role in environmental exposure-induced diseases by regulating gene expression. Therefore, we aim to investigate the role of m6A in DEHP-induced reproductive injury. MAIN METHODS We established an in vivo model of mice exposed to DEHP to explore the effect of DEHP on reproductive injury and m6A. To further explore the molecular mechanism of DEHP toxicity, we built a model of GC-2 cells exposed to mono-(2-ethylhexyl) phthalate (MEHP) in vitro and further silenced Mettl3 in GC-2cells. Besides, we also conducted MeRIP-qPCR and RIP assays to identify the target genes for m6A modification. KEY FINDINGS DEHP induced testicular injury and senescence. And telomeres shortening, reduced levels of telomere repeat-binding factor 1 (TRF1), TRF2, protection of telomeres 1 (POT1), and telomerase reverse transcriptase (TERT) can be observed in DEHP-treated testes. MEHP also induced GC-2 cellular senescence and telomere dysfunction. Besides, increased m6A mediated by METTL3 stabilized homeobox containing 1 (Hmbox1) in an m6A-dependent manner in MEHP-exposed GC-2 cells. Mettl3 knockdown led to lower m6A modification and reduced Hmbox1 stability, resulting in further shortening of telomere length. SIGNIFICANCE our work uncovered that DEHP led to male reproductive injury by telomere dysfunction and m6A modified Hmbox1 contributed to maintaining telomere homeostasis in this process, suggesting that accurate regulation of m6A modification level by drugs has potential value in the treatment of DEHP-induced male reproductive injury.

Abstract
Osteosarcoma (OS) is the most common primary malignant bone tumor, which usually occurs in children and adolescents. It is generally a high-grade malignancy presenting with extreme metastases to the lungs or other bones. The etiology of the disease is multifaceted and still remains obscure. A combination of surgery and chemotherapy has played a major role in the treatment of OS over the past three decades, and consequently, the overall survival rates for the disease have remained unchanged. Therefore, there is an urgent need to employ new comprehensive analyses and technologies to develop significantly more informative classification systems, with the aim of developing more effective and less toxic therapies for OS patients. This review discusses the existing knowledge of OS therapy and potential methods to develop novel therapeutic agents for the disease.

Abstract
Sperm DNA injury is one of the common causes of male infertility. Folic acid deficiency would increase the methylation level of the important genes, including those involved in DNA double-strand break (DSB) repair pathway. In the early stages, we analysed the correlation between seminal plasma folic acid concentration and semen parameters in 157 infertility patients and 91 sperm donor volunteers, and found that there was a significant negative correlation between seminal folic acid concentration and sperm DNA Fragmentation Index (DFI; r = -0.495, p < 0.01). Then through reduced representation bisulphite sequencing, global DNA methylation of sperm of patients in the low folic acid group and the high folic acid group was analysed, it was found that the methylation level in Rad54 promoter region increased in the folic acid deficiency group compared with the normal folic acid group. Meanwhile, the results of animal model and spermatocyte line (GC-2) also found that folic acid deficiency can increase the methylation level in Rad54 promoter region, increased sperm DFI in mice, increased the expression of γ-H2AX, that is, DNA injury marker protein, and increased sensitivity of GC-2 to external damage and stimulation. The study indicates that the expression of Rad54 is downregulated by folic acid deficiency via DNA methylation. This may be one of the mechanisms of sperm DNA damage caused by folate deficiency.

Abstract
AIM Male reproductive toxicity is becoming of growing significance due to clinical chemotherapy usage. Methotrexate (MTX) is an anti-folate used on a large scale for different tumors and autoimmune conditions. Despite its wide clinical use, MTX is associated with severe testicular intoxication. The exact underlying mechanism is unclear. METHODS Our study was conducted to explore the pathogenesis mechanism of MTX-induced testicular damage and the potential testicular protective effects of apocynin (APO) on testicular injury induced by single i.p. MTX (20 mg/kg). APO was administered orally (100 mg/kg) for ten days. RESULTS As compared to rats given MTX alone, co-administration of MTX with APO demonstrated multiple beneficial effects evidenced by a marked increase in testosterone, FSH, and LH and significantly restored testes histopathological alterations. Mechanistically, APO restored antioxidant status through up-regulation of Nrf2, cytoglobin, PPAR-γ, SIRT1, AKT, and p-AKT, while effectively lowering Keap-1. Moreover, APO significantly attenuated inflammation by down-regulating NF-κB-p65, iNOS, and TLR4 expressions confirmed by in-silico evidence. Additionally, network pharmacology analysis, a bioinformatics approach, was used to decipher various cellular processes' molecular mechanisms. SIGNIFICANCE The current investigation proves the beneficial effects of APO in MTX-associated testicular damage through activation of cytoglobin, Keap-1/Nrf2/AKT, PPAR-γ, SIRT1, and suppressing of TLR4/NF-κB-p65 signal. Our data collectively encourage extending the investigation to the clinical setting to explore APO effects in MTX-treated patients.

Abstract
The aim of the study was to investigate the protective effect of pyrrolidine dithiocarbamate (PDTC) against methotrexate (MTX)-induced testicular damage in rats. Forty Wistar albino male rats were divided into equally four groups: Control group (saline solution, IP), PDTC group (100 mg/kg PDTC,IP, 10 days), MTX group (20 mg/kg MTX, IP, single dose, on the 6th day) and MTX + PDTC group (100 mg/kg PDTC, IP, 10 days and 20 mg/kg MTX, IP, single dose, on the 6th day). After 10 days, testicular tissues were excised for morphometric, histological and immunohistochemical evaluations. Serum testosterone, follicle stimulating hormone (FSH), luteinizing hormone (LH) and prokineticin 2 (PK2) levels were determined. Body and testicular weights were measured. Testicular damage was assessed by histological evaluation. Nuclear factor kappa B (NFkB), nuclear factor erythroid 2 related factor 2 (Nrf2) and PK2 immunoreactivities were evaluated by HSCORE. Body and testicular weights, serum FSH, LH, testosterone levels, seminiferous tubule diameter and germinal epithelial thickness were significantly decreased in the MTX group. However, serum PK2 level, histologically damaged seminiferous tubules and interstitial field width were significantly increased. Additionally, there was an increase in NFkB and PK2 immunoreactivity, whereas there was a significant decrease in Nrf2 immunoreactivity. PDTC significantly improved hormonal, morphometric, histological and immunohistochemical findings. Taken together, we conclude that PDTC may reduce MTX-induced testicular damage via NFkB, Nrf2 and PK2 signaling pathways.

Abstract
Objective The present study aimed to investigate the possibility that curcumin (CMN) protects against methotrexate (MTX)-induced testicular damage by affecting the phospho-p38 (p-p38) mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways. Methods Eighteen male Wistar albino rats were randomly divided into three groups. The control group was given an intragastric administration of dimethyl sulfoxide (DMSO) daily for 14 days, the MTX group was given a single intraperitoneal dose of MTX (20 mg/kg) on the 11th day, and the MTX+CMN group was given intragastric CMN (100 mg/kg/day, dissolved in DMSO) for 14 days and a single intraperitoneal dose of MTX (20 mg/kg) on the 11th day. At the end of the experiment, all animals were sacrificed and the testicular tissues were removed for morphometry, histology, and immunohistochemistry. Body and testicular weights were measured. Results Body weights, seminiferous tubule diameter, and germinal epithelium height significantly decreased in the MTX group compared to the control group. Whereas, the number of histologically damaged seminiferous tubules and interstitial space width significantly increased in the MTX group. In addition, the number of p-p38 MAPK immunopositive cells and the immunoreactivity of NF-κB also increased in the MTX group compared to the control group. CMN improved loss of body weight, morphometric values, and histological damage due to MTX. CMN also reduced the number of p-p38 MAPK immunopositive cells and the NF-κB immunoreactivity. Conclusion CMN may reduce MTX-induced testicular damage by suppressing the p38 MAPK and NF-κB signaling pathways.

Abstract
INTRODUCTION Immunosuppressant drugs are increasingly being used in the reproductive years. Theoretically, such medications could affect fetal health either through changes in the sperm DNA or through fetal exposure caused by a presence in the seminal fluid. This systematic overview summarizes existing literature on the spermatotoxic and genotoxic potentials of methotrexate (MTX), a drug widely used to treat rheumatic and dermatologic diseases, and mycophenolate mofetil (MMF), which alone or supplemented with ganciclovir (GCV) may be crucial for the survival of organ transplants. MATERIAL AND METHODS The systematic overview was performed in accordance with the PRISMA guidelines: A systematic literature search of the MEDLINE and Embase databases was done using a combination of relevant terms to search for studies on spermatotoxic or genotoxic changes related to treatment with MTX, GCV or MMF. The search was restricted to English language literature, and to in vivo animal studies (mammalian species) and clinical human studies. RESULTS A total of 102 studies were identified, hereof 25 human and 77 animal studies. For MTX, human studies of immunosuppressive dosages show transient effect on sperm quality parameters, which return to reference values within 3 months. No human studies have investigated the sperm DNA damaging effect of MTX, but in other organs the genotoxic effects of immunosuppressive doses of MTX are fluctuating. In animals, immunosuppressive and cytotoxic doses of MTX adversely affect sperm quality parameters and show widespread genotoxic damages in various organs. Cytotoxic doses transiently change the DNA material in all cell stages of spermatogenesis in rodents. For GCV and MMF, data are limited and the results are indeterminate, for which reason spermatotoxic and genotoxic potentials cannot be excluded. CONCLUSIONS Data from human and animal studies indicate transient spermatotoxic and genotoxic potentials of immunosuppressive and cytotoxic doses of MTX. There are a limited number of studies investigating GCV and MMF.

Abstract
OBJECTIVES Methotrexate (MTX) is an anticancer drug used in chemotherapy. MTX was known for its toxic effects involving most of the organs including testis. Bee pollen is healthy food for human and has antioxidant effect. We intended to determine protective effect of bee pollen against testicular injury caused by MTX in rats. METHODS Thirty-two adult Sprague Dawley male rats were used, and 4 groups were formed: control, MTX, pollen, and MTX + pollen. Rats were given pollen at a dose of 400 mg/kg with intragastric gavage for 10 days. On day 7, MTX was administered a single dose of 30 mg/kg ip. Serum testosterone and LH, tissue MDA level, and SOD and CAT enzyme activities were examined. In addition, spermatological parameters were evaluated. RESULTS MDA level and SOD activity increased while testosterone level decreased significantly in the MTX group compared to the control group. In the MTX + pollen group, MDA level and SOD activity decreased while testosterone level increased. There was no significant change in CAT activity and LH values. Abnormal sperm ratio decreased in the MTX + pollen group compared to the MTX group. CONCLUSIONS Our results suggest that bee pollen has a healing effect on reproductive parameters in testicular damage caused by MTX.

Vitamin B17 Ameliorates Methotrexate-Induced Reproductive Toxicity, Oxidative Stress, and Testicular Injury in Male Rats. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:4372719. [PMID: 33194002 PMCID: PMC7641263 DOI: 10.1155/2020/4372719] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 09/03/2020] [Accepted: 10/14/2020] [Indexed: 02/07/2023]
Abstract
Methotrexate (MTX; 4-amino-10-methylfolic acid) is a folic acid reductase inhibitor used to treat autoimmune diseases and certain types of cancer. Testicular toxicity resulting from MTX is a significant side effect that may cause subsequent infertility. The present study was conducted to examine the ameliorating effects of vitamin B17 (VitB17) against testicular toxicity induced by MTX in male rats. A total of 50 male albino rats were equally divided into five groups [control group; vitamin B17 group (VitB17) administered VitB17 only; methotrexate group administered MTX only; cotreated group, (VitB17+MTX) and posttreated group (MTX+VitB17)]. In methotrexate group (MTX), a significant decrease was observed in body weight and the testicular weight, as well as the levels of plasma testosterone, luteinizing hormone and follicle-stimulating hormone compared with control. The sperm count, viability, morphology index, total motility, and progressive motility also decreased in MTX rats compared with control. Furthermore, the levels of reduced glutathione, catalase, and superoxide dismutase, as well as proliferating cell nuclear antigen protein expression, in the testicular tissue decreased in MTX compared with control. In addition, MTX caused a significant increase in DNA and tissue damage compared with control. However, VitB17 ameliorated these effects, indicating that it has a preventative and curative effect against MTX-induced reproductive toxicity in male rats. The protective effect of VitB17 may be associated to its antioxidant properties as it possibly acts as a free-radical scavenger and lipid peroxidation inhibitor, as well as its protective effect on the levels of GSH, SOD, and CAT.

Abstract
The current study aimed to investigate the protective potential of Chlorella Vulgaris (CV) extract against the reproductive dysfunction induced by sodium nitrite toxicity. Forty-five male Wistar albino rats were assigned into five groups (n = 9). Control group received normal saline orally for 3 months, CV-treated: administered CV extract (70 mg/kg.BW) orally for 3 months, sodium nitrite-treated: received sodium nitrite (80 mg/kg.BW) orally for 3 months, co-treated: simultaneously received CV along with sodium nitrite treatment, orally, daily for 3 months, and CV-pre-treated: pre-treated with CV extract for 4 weeks followed by simultaneous treatment with sodium nitrite and CV extract for additional 8 weeks. Treatment with sodium nitrite significantly decreased serum testosterone and follicle-stimulating hormone concentrations, sperm count, motility, and viability. Besides, it decreased testicular superoxide dismutase and glutathione peroxidase activities while increased malondialdehyde concentration. This effect of sodium nitrite was associated with degenerative, necrotic, vascular, and inflammatory changes in testicular tissues. Treatment of sodium nitrite-intoxicated rats with CV in co-treated and pre-treated groups significantly prevented sodium nitrite-induced alterations of sperm parameters, hormonal concentrations, testicular oxidative-antioxidant status, and histological architecture. This study indicates that CV extract ameliorates the reproductive dysfunction induced by sodium nitrite toxicity via improving reproductive hormonal levels and testicular antioxidant activities.

Abstract
Background/aim Methotrexate (MTX), widely used as a drug in cancer, has many adverse effects on tissues. Apocynin (APO) is a NADPH oxidase inhibitor and is known with many antioxidant properties. In this study, we aimed to evaluate the adverse effects of MTX on testicular tissue and the protective effects of APO at two different doses (20 mg/kg and 50 mg/kg) on MTX-induced testicular damage. Materials and methods Fifty adult male Wistar albino rats (8 weeks old and weighing 200–250 g) were divided into five groups of 10 rats each: 1. saline control, 2. dimethyl sulfoxide (DMSO) control, 3. MTX, 4. APO-20 + MTX, and 5. APO-50 + MTX. All injections were performed intraperitoneally. At the end of day 28, all rats were sacrificed under anesthesia. The testes were evaluated histologically and the blood samples were analyzed biochemically. Results According to histological and biochemical analyses, there was no significant difference between the DMSO and control groups. In terms of the histological findings, MTX group was significantly the worst affected group compared to the others, and in this group, apoptotic cell number (P = 0.011) was significantly increased in comparison with the control group. Except MTX, there was no significant difference in apoptotic cell number of the other groups compared to the control group. In the MTX group, malondialdehyde (MDA, P = 0.017) and myeloperoxidase (MPO, P < 0.001) levels were significantly increased in tissue and in blood (MDA P < 0.001, MPO P < 0.001), while tissue glutathione (GSH, P < 0.05) and serum testosterone levels (P < 0.01) were decreased compared with the control group. APO + MTX treatment groups exhibited better testis morphology, and apoptotic cells were also significantly decreased compared to MTX group (P < 0.001). Conclusion Our results suggest that MTX induced defects on testis via oxidative stress and APO reversed the effects of MTX with its antioxidant properties.

Abstract
Methotrexate (MTX) is a widely used chemotherapeutic agent but its clinical use is challenged with different forms of toxicities including testicular injury. The aim of the current study was to evaluate the potential protective effect of potassium channel opener, nicorandil (NIC) (3 and 10 mg/kg/day) on MTX-induced testicular injury in a rat model. Rats were randomly divided into four groups (nine rats each) and treated for 2 weeks as follows: (I) normal control (CON group) received vehicle, (II) model group (MTX group) given MTX (20 mg/kg) single intraperitoneal (i.p.) injection dose on 11th day, (III) MTX + NLD group treated with NIC (3 mg/kg/day) orally for 2 weeks and MTX (20 mg/kg) single i.p. dose on 11th day, and (IV) MTX + NHD group treated with NIC (10 mg/kg/day) orally for 2 weeks and MTX (20 mg/kg) single i.p. injection on the 11th day. The testicular injury was assessed biochemically via serum testosterone, total antioxidant capacity, testicular oxidative stress parameters, P-glycoprotein, tumor necrosis factor-alpha, and interleukin-1β. Furthermore, histopathological evaluation, endothelial nitric oxide synthase (eNOS) immunoexpression, and detection of p53 expression level using Western blotting were performed. Results showed that MTX induced testicular injury which was proved by both biochemical and histopathological evaluations. Our results concluded that NIC pretreatment attenuated MTX-induced testicular injury via significantly increased eNOS immunoexpression, antiapoptotic, anti-inflammatory, and antioxidant properties. Interestingly, NIC high dose is more protective than low dose.

Abstract
PURPOSE Although cancer predominantly affects people at older ages, a substantial number of patients, like breast cancer patients, are diagnosed before they have completed their families or even before giving birth. Furthermore, cytotoxic chemotherapy may be required in addition to treat cancer survivors. The present study was conducted to investigate the protective effect of oxytocin (OT) on methotrexate (MTX)-induced ovarian toxicity in rats. METHODS Eighteen adult female Sprague-Dawley rats were used in the study. All rats were divided randomly into three groups. The control group (n = 6) received no treatment. The remaining 12 rats received a single dose of 20 mg/kg of MTX. Half of the rats (n = 6) were treated with 1 mg/kg/day of saline, and the other half (n = 6) were treated with 160 µg/kg/day of OT for 21 days. Then, blood samples were collected for biochemical analysis, and an ovariectomy was performed for histopathological examination. RESULTS Plasma malondialdehyde (MDA) and transforming growth factor-β (TGF-β) levels were significantly lower in the MTX + OT group compared to the MTX + saline group (p = 0.000036 for MDA; p = 0.0044 for TGF-β). AMH levels were also significantly higher in the MTX + OT group than in the MTX + saline group (p = 0.000036). The ovarian fibrosis percent was also notably lower in the MTX + OT group than in the MTX + saline group (p = 0.000036). CONCLUSION On the basis of these findings, OT is a promising agent for ameliorating harmful effects of MTX on rat ovaries in an experimental model.

Abstract
The aim of this study was to investigate the possible prophylactic effects of agomelatine (AGO) against testicular and epididymal damage induced by methotrexate (MTX) in rats. Twenty-four male Wistar albino rats were divided into three groups: Group I (control group), Group II (MTX group: 20 mg/kg MTX, i.p, single dose), and Group III (MTX+AGO group: 20 mg/kg MTX, i.p, single dose+40 mg/kg AGO; gavage, 7 days). The rats were killed under anesthesia 24 hours after the last AGO application. Testicular and epididymal tissues were bilaterally removed for morphometric, biochemical, pathological, and immunohistochemical analyses. Body, testicular, and epididymal weights were measured. Malondialdehyde (MDA), superoxide dismutase, catalase, and glutathione peroxidase levels were measured in testes. Sperm count, hyperemia, edema, inflammatory reaction, degenerated and necrotic cells were evaluated by histopathological analysis. In addition, inducible nitric oxide synthase (iNOS), granulocyte colony-stimulating factor (G-CSF), osteopontin (OPN), and heat shock protein-70 (HSP70) immune reactions were analyzed in testes and epididymides. Decreased epididymal weights, increased MDA levels, decreased sperm count, hyperemia, edema, inflammatory reaction, and degenerated and necrotic cells were observed in the MTX group. In addition, iNOS, HSP70, G-CSF, and OPN immune reactions were increased. AGO improved morphometric, biochemical, histopathological, and immunohistochemical findings. The present study confirms that MTX induces testicular and epididymal damage both biochemically and immunohistochemically. However, AGO demonstrated ameliorative effects on both biochemical and pathological findings of the current study.

Abstract
Dihydrofolate reductase inhibitors are an important class of drugs, as evidenced by their use as antibacterial, antimalarial, antifungal, and anticancer agents. Progress in understanding the biochemical basis of mechanisms responsible for enzyme selectivity and antiproliferative effects has renewed the interest in antifolates for cancer chemotherapy and prompted the medicinal chemistry community to develop novel and selective human DHFR inhibitors, thus leading to a new generation of DHFR inhibitors. This work summarizes the mechanism of action, chemical, and anticancer profile of the DHFR inhibitors discovered in the last six years. New strategies in DHFR drug discovery are also provided, in order to thoroughly delineate the current landscape for medicinal chemists interested in furthering this study in the anticancer field.

BACKGROUND The male reproductive system is a sensitive and intricate process that can be distressed following exposure to various toxicants. Therapeutic drugs, especially chemotherapeutics, can also adversely affect male fertility by instigating hormonal changes leading to testicular cells injury. Azathioprine (AZA) is an effective anticancer drug, but some cases of testicular toxicity have been reported. The aim of this work was to investigate the protective effects of taurine chloramine (TAU-Cl), a reported antioxidant and antiinflammtory peptide, against AZA-induced testicular dysfunction in male rats and ascertain the contributing mechanisms. METHODS Forty male rats were allocated into four equal groups; (i) normal control rats, (ii) TAU-Cl group (100 mg/kg b.w/day for 10 weeks, (iii) AZA group (5 mg/day for 4 weeks); (iv) TAU-Cl/AZA group. RESULTS AZA caused increased DNA damage in the testes, and alterations in sex hormones and sperm quality, including sperm count, viability, and motility. Moreover, testicular tissue from the AZA-treated group had increased levels of oxidative stress indicator, MDA, and decreased activity of the antioxidant enzymes as superoxide dismutase (SOD), reduced glutathione (GSH) and catalase (CAT) levels. These deleterious events were accompanied by upregulated levels of the pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α), and protein expression of iNOS and NFκB-p65, interleukin-1beta (IL-1β), and proapoptotic marker; caspase-9, together with decreased Bcl-2, NrF2 and hemeoxygenase (HO-1) expression. In contrast, TAU-Cl pretreatment significantly abrogated these toxic effects which were confirmed histologically. CONCLUSION Pretreatment with TAU-Cl exerts a protective effect against AZA-induced male reproductive testicular atrophy. This finding could open new avenues for the use of TAU-Cl as a complementary approach to chemotherapy supportive care.

Abstract
Prescribing for pregnant or lactating patients and male patients wishing to father children can be a difficult area for dermatologists. There is a lack of review articles of commonly used systemic medications in dermatology with respect to their effects on developing embryogenesis and their potential transfer across the placenta, in breast milk and in seminal fluid. This paper aims to provide an up to date summary of evidence to better equip dermatologists to inform patients about the effects of systemic medications commonly used in dermatology to treat conditions such as atopic dermatitis, psoriasis and acne, on current and future embryogenesis and fertility.

Abstract
The purpose of this study was to determine the kisspeptin-10 (Kiss) administration on the damages in testicular oxidant-antioxidant system, reproductive organ weights and some spermatological characteristics resulted from methotrexate (MTX) exposure. Group 1 (n:6) received saline only; group 2 (n:6) received 50 nmol/kg kisspeptin-10 for 10 days; group 3 (n:10) received single-dose methotrexate 20 mg/kg; and group 4 (n:10) received MTX 20 mg/kg single dose and, after 3 days, received kisspeptin-10, 50 nmol/kg, lasted for 10 days by intraperitoneal injection. At the end of the study, malondialdehyde levels were found to have increased following the application of MTX while showing a significant reduction in group 4 with Kiss administration. With respect to the spermatological parameters, administering MTX decreased motility and increased the rates of abnormal spermatozoa in group 2, while improvements were observed in group 4 in the form of increased motility in the spermatozoa and fewer abnormal spermatozoa. In addition, Kiss treatment provided statistically significant increases in the absolute weight of the seminal vesicles and the relative weights of the right cauda epididymis and seminal vesicles resulting from MTX administration. MTX administration damaged some spermatological parameters and increased oxidative stress when compared to the control group. However, Kiss treatment was observed to mitigate these adverse effects as demonstrated by the improvements in coadministration of Kiss and MTX when compared to the MTX group. It is concluded that Kiss treatment may reduce MTX-induced reproductive toxicity as a potential antioxidant compound.

Abstract
The use of dietary antioxidants to modulate the toxic side effects induced by the anticancer drugs used in chemotherapy is currently eliciting considerable interest. This study was undertaken to investigate the possible protective role of the antioxidant curcumin (CMN) against genotoxicity, cytotoxicity and oxidative stress induced by cisplatin and methotrexate. Male mice were administered CMN orally in the dosages of 60, 90, and 120 mg/kg for three consecutive days before a single intraperitoneal injection of either cisplatin (6.5 mg/kg) or methotrexate (10 mg/kg). Animals were sacrificed 24 h after treatment with the used anticancer drugs. The protective role of CMN against the genotoxic and cytotoxic effects of the tested anticancer drugs was evaluated by using micronucleus and comet assay. The oxidative stress induced by the two anticancer drugs was assessed by determining malondialdehyde and reduced glutathione levels in kidney tissues. The results indicated that CMN pretreatment at the tested doses reduced the incidence of micronuclei and DNA damage induced by cisplatin and methotrexate. Moreover, malondialdhyde level was significantly decreased while glutathione level was significantly increased in CMN pretreated groups compared with cisplatin- and methotrexate-treated groups. This protective effect of CMN could be attributed to its ability to scavenge reactive oxygen species.

Abstract
BACKGROUND Inflammatory bowel disease incidence peaks during the reproductive years. Methotrexate (MTX) is frequently used for inflammatory bowel disease, but its use during pregnancy is contraindicated in women because of teratogenic effects. The aim of this review is to investigate the influence of MTX on male fertility and pregnancy outcomes after paternal MTX exposure. METHODS A systematic literature search was performed by applying 2 focus areas, "methotrexate" and "male fertility or pregnancy outcome." Terms and keywords were used both as MeSH terms and free-text searches. Pertinent articles were searched for additional relevant references. RESULTS In animal studies, MTX induces aberrations in sperm DNA that have not been identified in humans. The effects of MTX on human sperm quality have only been described in case reports. A transient adverse effect on sperm quality with low-dose MTX has been reported, but several other cases have not found harmful effects of MTX. MTX has not been measured in human sperm ejaculates; yet, the risk of a direct toxic effect on the fetus through MTX-contaminated seminal plasma seems negligible. Until now, 284 pregnancies with paternal MTX exposure have been reported. The outcomes were 248 live births and a total of 13 malformations, with no overt indication of MTX embryopathy. CONCLUSIONS This review reveals the lack of studies on the safety of MTX with regard to male reproduction. It is not clear whether MTX transiently influences male fertility and sperm DNA integrity, and more studies are needed. Comparative cohort studies found no increased risk of adverse pregnancy outcomes.

Abstract
Prolonged use of immunosuppressant medications is occasionally seen in infertile men with chronic inflammatory conditions; autoimmune disorders; or an organ or hematopoietic stem cell transplant. Chronic inflammation impacts negatively on male reproductive endpoints, so immunosuppressant therapy can produce improvements. Corticosteroids have been used to treat antisperm antibodies and even as an empirical treatment for male infertility in general. Trials of these methods have provided mixed results on semen quality and fertility, with improvement, no change and negative effects reported by different investigators. In a substantial number of observational studies, patients on long-term therapy with prednisone for chronic inflammatory disease, testosterone levels were lower compared to untreated controls, though randomized controlled trials have not been conducted. Similarly decreases in testosterone have been reported in men receiving corticosteroids to minimize transplant rejection; however, most were treated with multiple immunosuppressive medications that may have contributed to this effect. A large number of trials of healthy men treated with corticosteroids have shown some disruption in reproductive hormone levels, but other studies reported no effect. Studies in monkeys, rats (at human equivalent dose), cattle, sheep, and horses have shown endocrine disruption, including low testosterone with dexamethasone treatment. Of the cytostatic immunosuppressives, which have high potential for cellular damage, cyclophosphamide has received the most attention, sometimes lowering sperm counts significantly. Methotrexate may decrease sperm numbers in humans and has significant negative impacts in rodents. Other chemotherapeutic drugs used as immunosuppressants are likely to impact negatively on male fertility endpoints, but few data have been collected. The TNF-α Inhibitors have also received little experimental attention. There is some evidence that the immunophilin modulators: cyclosporine, sirolimus, and everolimus cause endocrine disruption and semen quality impairment. As we review in this chapter, results in experimental species are concerning, and well-designed studies are lacking for the effects of these medications on reproductive endpoints in men.

Abstract
OBJECTIVE Methotrexate (MTX) leads to acute toxic side effects in tissues or organs containing rapidly dividing cells such as seminiferous tubules. In this study, we investigated the protective effects of vitamin C against MTX-induced injury in rat testis. MATERIAL AND METHODS A total of 31 rats were divided into 4 groups, including the control group. The study was completed within 4 weeks and the rats received daily doses of 2 mL/kg SF, 100 mg/kg vitamin C and 10 mg/kg/day MTX i.p according to their groups. The mean seminiferous tubular diameter, germinal epithelial cell thickness, and mean testicular biopsy score were determined by histologic examination of each group. RESULTS The vitamin C + MTX group showed more similarity with the control group. Statistically significant results were achieved between groups as for mean seminiferous tubular diameter, germinal epithelial cell thickness, and mean testicular biopsy score. When compared with the group which received vitamin C after MTX therapy, values for mean seminiferous tubular diameter, germinal epithelial cell thickness, and mean testicular biopsy score were significantly higher in the group which received vitamin C before initiation of MTX therapy. CONCLUSION Vitamin C decreased MTX-induced testicular histological injuries, especially when used before MTX therapy.
