Supraphysiological doses of nandrolone decanoate disrupts spermatogenesis but did not interfere on embryo rate. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024; 397:4025-4034. [PMID: 37999756 DOI: 10.1007/s00210-023-02847-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Accepted: 11/09/2023] [Indexed: 11/25/2023]
Abstract
The aim of this study was to investigate the effects of 10 mg/kg/week of nandrolone decanoate (DECA - Deca Durabolin®) on body composition, hormonal levels, spermatic parameters, redox status, and morphometric parameters of testicle and epididymis; furthermore, the fertility capacity of Wistar rats was measured thought in vitro fertilization (IVF). The animals (n = 16) were divided into two groups: control group (CTRL, n = 8), which received only vehicle composed by peanut oil and 10% of the benzoic alcohol and nandrolone decanoate group (DECA, n = 8), which received intramuscular injections of DECA for 8 weeks, both groups were treated for 8 weeks. The results demonstrate significative decrease in visceral fat, testosterone levels, and thiol content on epididymis, reduction on normal sperm parameters, and deleterious effect on testicles and epididymis tissue morphology showing reduction of germ height and luminal diameter on the DECA group. Thus, it can be concluded that high doses of nandrolone decanoate impairs male reproductive parameters.

Retinoic acid mitigates the NSC319726-induced spermatogenesis dysfunction through cuproptosis-independent mechanisms. Cell Biol Toxicol 2024; 40:26. [PMID: 38691186 PMCID: PMC11062974 DOI: 10.1007/s10565-024-09857-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Accepted: 03/25/2024] [Indexed: 05/03/2024]
Abstract
Copper ionophore NSC319726 has attracted researchers' attention in treating diseases, particularly cancers. However, its potential effects on male reproduction during medication are unclear. This study aimed to determine whether NSC319726 exposure affected the male reproductive system. The reproductive toxicity of NSC319726 was evaluated in male mice following a continuous exposure period of 5 weeks. The result showed that NSC319726 exposure caused testis index reduction, spermatogenesis dysfunction, and architectural damage in the testis and epididymis. The exposure interfered with spermatogonia proliferation, meiosis initiation, sperm count, and sperm morphology. The exposure also disturbed androgen synthesis and blood testis barrier integrity. NSC319726 treatment could elevate the copper ions in the testis to induce cuproptosis in the testis. Copper chelator rescued the elevated copper ions in the testis and partly restored the spermatogenesis dysfunction caused by NSC319726. NSC319726 treatment also decreased the level of retinol dehydrogenase 10 (RDH10), thereby inhibiting the conversion of retinol to retinoic acid, causing the inability to initiate meiosis. Retinoic acid treatment could rescue the meiotic initiation and spermatogenesis while not affecting the intracellular copper ion levels. The study provided an insight into the bio-safety of NSC319726. Retinoic acid could be a potential therapy for spermatogenesis impairment in patients undergoing treatment with NSC319726.

Zinc oxide resveratrol nanoparticles ameliorate testicular dysfunction due to levofloxacin-induced oxidative stress in rats. Sci Rep 2024; 14:2752. [PMID: 38307943 PMCID: PMC10837121 DOI: 10.1038/s41598-024-52830-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Accepted: 01/24/2024] [Indexed: 02/04/2024] Open
Abstract
The present work is aimed to assess the protective influence of zinc oxide resveratrol nanoparticles against oxidative stress-associated testicular dysfunction. The number of 50 male albino rats were randomly separated into five groups (n = 10): Group I, control: rats gavage distilled water orally; Group II, Levofloxacin: rats that administered Levofloxacin (LFX) softened in distilled water at a dosage of 40 mg/kg-1 BW orally every other day; Group III, Zn-RSV: rats administered with Zn-RSV (zinc oxide resveratrol in distilled water at a dose 20 mg/kg-1 BW orally every other day; Group IV, (LFX + Zn-RSV): rats that were administered with Levofloxacin along with Zn-RSV nPs; Group V, Levofloxacin + Zn: rats were administered with Levofloxacin and Zno at a dose of 20 mg/kg-1 BW orally every other day as mentioned before. This study lasted for 2 months. Sera were collected to assess luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone values. Testicular tissues were utilized to evaluate levels of superoxide dismutase (SOD), nitric oxide (NO), malondialdehyde (MDA), and catalase (CAT). Semen samples were utilized to measure their quality (motility, concentration, and vitality). Histopathological and immune histochemical techniques investigated the morphological changes in the testis. Rats treated with Levofloxacin showed significantly lower levels of serum LH, testosterone, FSH, testicular enzymatic NO, catalase, SOD, BAX, and BCL-2 immune reactivity and sperm quality but significantly greater testicular malondialdehyde and caspase-3 immuno-reactivity Compared to both control and zinc oxide resveratrol treatment. Zinc oxide resveratrol nanoparticles ameliorated the harmful side effects of Levofloxacin. Improvements were more pronounced in the co-treatment (LFX + Zn-RSV) Zinc oxide resveratrol group than in the co-treatment (LFX + Zno) Zinc oxide group. Zinc oxide resveratrol nanoparticles could be a possible solution for levofloxacin oxidative stress-induced fertility problems.

Alsyaad KM. Ameliorative impacts of propolis against testicular toxicity promoted by doxorubicin. Vet World 2024; 17:421-426. [PMID: 38595651 PMCID: PMC11000489 DOI: 10.14202/vetworld.2024.421-426] [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: 11/30/2023] [Accepted: 01/31/2024] [Indexed: 04/11/2024] Open
Abstract
Background and Aim Doxorubicin (DOX) is often used as a chemotherapeutic agent, although it may damage testicular functions. This study was designed to investigate the protective effects of propolis on testicular histological changes, semen parameters, and testosterone concentrations as a means of protecting against testicular damage caused by DOX chemotherapy. Materials and Methods Forty-eight male Wistar rats were divided into four groups with 12 animals per group. The first group served as the control. Rats in the second group were administered 4 mg/kg DOX. The third group was administered 4 mg/kg of DOX and 30 mg/kg b.w. propolis. The fourth group was orally dosed daily with 30 mg/kg b.w. propolis. Results DOX treatment resulted in a significantly decreased weight gain (WG) rate compared with the control, whereas DOX + propolis resulted in improved WG and returned to the normal range. Testosterone levels were comparable among the experimental groups, with a significant increase in the propolis-treated group. In addition, DOX-treated groups exhibited a remarkable depletion in sperm counts, motility, and viability compared to the other groups. Conclusion Most of the histological and hormonal changes resulting from the toxicity of DOX returned to almost normal after treatment of rats with the aqueous extract of propolis, indicating that propolis ameliorated the effects of DOX poisoning on testicular function in male rats.

Reprod Toxicol 2024; 123:108516. [PMID: 38042436 DOI: 10.1016/j.reprotox.2023.108516] [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: 07/16/2023] [Revised: 10/27/2023] [Accepted: 11/22/2023] [Indexed: 12/04/2023]
Abstract
There is evidence that sperm count has progressively declined in men over the recent decades. Exposure to air pollutants including petrol and diesel exhaust have been reported to impair male reproduction although there is little experimental evidence. This study investigated the effects of petrol-generator exhaust fumes (PGEF) on semen, sperm, gonadal structure and hormonal status in the dog. Sixteen adult male Basenji dogs were randomly assigned four to each of 4 groups as follows: an unexposed (Control) group and three groups exposed to graded levels of PGEF for 1, 2 or 3 h per day (hpd), respectively, for 90 days. Serum concentrations of testosterone (T), follicle stimulating hormone (FSH) and luteinizing hormone (LH) were measured on days 0 (baseline), 30, 60 and 90 of the study. At day 90, semen samples were collected for semen and sperm analysis. Testicular and epididymal tissues were subjected to gross, histopathological and histomorphometric evaluation. Graded exposure to PGEF resulted in increased serum concentration of T and decreased concentrations of FSH and LH, increased seminal plasma lipid peroxidation, seminiferous and epididymal tubular degeneration, germ cell depletion, lowered sperm concentration, decreased sperm motility and vitality, and increased sperm abnormal morphology. The close proximity between dogs and humans in exposed environments underscores the importance of these findings to human reproductive health and fertility. The findings suggest that with prolonged exposure, the impairment of reproductive functions will likely play significant roles in the decline in male fertility.

Abstract
Background The ancient science of life known as Ayurveda uses a variety of formulations or herbal compounds to treat a wide range of illnesses. Male infertility accounts for half of all infertility worldwide, and numerous etiological variables play a role. A pharmacologically active tobacco component called nicotine has a negative impact on male fertility and the reproductive system. Musalyadi Churna (MSC) is one of the polyherbal compound formulations mentioned in Ayurveda Classics for aphrodisiac therapy and recommended for the treatment of male infertility. Objective The current study aims to evaluate the spermatogenic potential of MSC along with its protective effect against testicular degeneration induced by nicotine in rat models. Materials and Methods Sixty adult Sprague-Dawley male rats were used in the experiment, which were divided into ten groups of six rats each. Nicotine was administered orally as disease control. The standard and vehicle control were also included along with study drug groups in which MSC was administered orally to the rats. The study was conducted for 70 days for each group with assessment of body weight and food consumption. After treatment, rats were weighed and sacrificed for evaluation of parameters like organ weight, epididymal sperm count, and sperm morphology along with histological assessment. The data were statistically evaluated using analysis of variance test and Bonferroni multiple-comparison range test to compare different treatment groups. Results and Conclusion In the present study, MSC possesses substantial spermatogenic efficacy, and the result indicates that the study drug possesses a protective effect against nicotine-induced impaired testicular functions in rats, but further research to elucidate its exact mechanism of action is essential.

Abstract
Rodents have been the preferred models for the evaluation of the toxicity of pollutants and drugs and their genotoxic effects, including sperm shape abnormalities. The scientific literature is dominated by studies conducted with model animals in laboratory conditions, but a generally accepted and standardized protocol addressing the optimal number of sperm cells to count is still lacking. In this study, we reviewed the literature regarding the number of counted sperm cells in such assessments, published from 1969 to 2023. To infer the number of counts providing the best cost/benefit regarding the robustness of the assay results, a new dataset involving the analysis of two populations of wild rodents was produced. We evaluated the frequency of sperm shape abnormalities in a total of 50 wild brown rats (Rattus norvegicus) captured in two port cities, aiming to detect the impact of differential sperm cell counts in the obtained results. During necropsy, the fresh epididymis tail of adult male rats was excised, and sperm cells were fixated in slides. For each animal, a total of 300, 500, 1000, and 2000 cells were sequentially counted, and head abnormalities were registered. Counting 300 sperm cells failed to detect significant differences between groups and 500 counts resulted in marginally significant differences. Only when 1000 or 2000 sperm cells were counted, significant differences emerged between groups. We propose that studies addressing sperm shape abnormalities should standardize counts to an optimal value of 1000 cells per animal, warranting robust statistical results while providing the best compromise concerning labor time.

Abstract
Epidemiological studies have established an association between chronic exposure to PM2.5 and male infertility. However, the underlying mechanisms were not fully revealed. In this study, we established mice models exposed to PM2.5 for 16 weeks, and a significant decrease in sperm quality accompanied by an increase in testosterone levels were observed after PM2.5 exposure. Moreover, treatment with ferrostatin-1 (Fer-1), a specific ferroptosis inhibitor, effectively mitigated PM2.5-induced testicular dysfunction in mice. And lipid peroxidation and ferritin accumulation were found to be significantly increased in Leydig cells of testes with a PM2.5-dose dependent manner. Further investigations revealed that TM-3 cells, a mouse Leydig cell line, were prone to ferroptosis after PM2.5 exposure, and the cell viability was partly rescued after the intervention of Fer-1. Furthermore, our results supported that the ferroptosis of TM-3 cells was attributed to the upregulation of ferredoxin 1 (FDX1), which was the protein transferring electrons to cytochrome P450 family 11 subfamily A member 1 to aid lysing cholesterol to pregnenolone at initial of steroidogenesis. Mechanically, PM2.5-induced FDX1 upregulation resulted in cellular ROS elevation and ferrous iron overload, which together initiated an autoxidation process of polyunsaturated fatty acids in the cell membrane of Leydig cells until the accumulated lipid peroxides triggered ferroptotic cell death. Simultaneously, upregulation of FDX1 promoted steroidogenesis and let to an increased level of testosterone. In summary, our work suggested that FDX1, a mediator involving steroidogenesis, was a key regulator in PM2.5-induced Leydig cells ferroptosis.

Abstract
Methadone (Met) is the most common treatment for opioid addiction. Although Met is effective for treatment of opioid dependence, sexual dysfunctions and infertility have been reported as a major problem in patients under Met treatment. The present study aimed to evaluate the effect of melatonin and N-acetylcysteine (N) on morphine and Met-induced oxidative stress, apoptosis, suppression of blood sexual hormones, impairment in sperm parameters, and sexual dysfunction. Adult male Wistar rats (n = 66) were randomly divided into 11 equal groups (n = 6) as follows: control, sham, morphine, Met, Met+N, Met+ melatonin, Met+melatonin+N, morphine+ Met, morphine+Met+ melatonin, morphine+Met+N, and morphine+Met+ melatonin+N groups. On day 56 post-treatment, the blood was collected from the tail and the serum levels of sex hormones were evaluated, then the rats were sacrificed, and their bilateral testes and epididymis were retrieved for histological, immunohistochemical, molecular, testicular tissue stress oxidative status, and sperm parameters assays. Exposure to morphine, Met, and shift of morphine to Met resulted in testicular degeneration that can be attributed to generating the stress oxidative-induced- apoptotic testicular cell death and impairing spermatogenesis. Melatonin and N alone and particularly, in combination with each other improved testicular degeneration, sex hormone suppression, and testicular function mediated by increasing the testicular antioxidant capacity and inhibition of the apoptosis pathway. It's suggested that oral administration of antioxidants may be an effective treatment for attenuating some opioid-related testicular dysfunction and degeneration.

A caffeine pre-treatment and sole effect of bone-marrow mesenchymal stem cells-derived conditioned media on hyperglycemia-suppressed fertilization. Biomed Pharmacother 2023; 165:115130. [PMID: 37413898 DOI: 10.1016/j.biopha.2023.115130] [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: 03/31/2023] [Revised: 06/26/2023] [Accepted: 07/02/2023] [Indexed: 07/08/2023] Open
Abstract
As a common metabolic disorder, hyperglycemia (HG) affects and disrupts the physiology of various systems in the body. Transplantation of mesenchymal stem cells (MSCs) has been used to control the complications of disease. Most of the therapeutic properties of MSCs are attributed to their secretome. This study aimed to investigate the effects of conditioned media extracted from sole or caffeine pre-treated bone-marrow-derived MSCs on hyperglycemia-induced detrimental impact on some aspects of reproduction. The HG was induced by intraperitoneally injection of streptozotocin (65 mg/kg) and nicotinamide (110 mg/kg). Twenty-four male Wistar rats (190 ± 20 g) were divided into control, HG, and the hyperglycemic groups receiving conditioned media of proliferated MSCs solely (CM) or MSCs pre-treated with caffeine (CCM). During the 49-day treatment, body weight and blood glucose were measured weekly. Finally, HbA1c, spermatogenesis development, sperm count, morphology, viability, motility, chromatin condensation, and DNA integrity were examined. Also, testicular total antioxidant capacity (TAC), malondialdehyde, sperm fertilization potential, and pre-implantation embryo development were evaluated. A one-way ANOVA and Tukey's post-hoc tests were used to analyze the quantitative data. The p < 0.05 was considered statistically significant. The CM and with a higher efficiency, the CCM remarkably (p < 0.05) improved body weight and HG-suppressed spermatogenesis, enhanced sperm parameters, chromatin condensation, DNA integrity, and TAC, reduced HbA1c, sperm abnormalities, and malondialdehyde, and significantly improved pre-implantation embryo development versus HG group. The conditioned media of MSCs solely (CM) and more effectively after pre-treatment of MSCs with caffeine (CCM) could improve spermatogenesis development, sperm quality, pre-implantation embryo development, and testicular global antioxidant potential during hyperglycemia.

Abstract
Low testosterone levels are caused by alcoholism, cigarette smoking, and exposure to toxic chemicals. This work focused on investigating the activities of propolis (PE) and bee pollen (BPE) extracts in reducing the oxidative stress of carbon tetrachloride (CCl4) in male mice models. The 48 male Swiss Albino mice weighed 27.5 ± 2.5 g and were divided into: Group1: Control (-) received distilled water only through oral intubation; Group 2: Control (- -) received corn oil by intraperitoneal (i.p.) injection once a day; Group 3: Control (+) received a sublethal dose of CCL4 intraperitoneally the end of the experiment. Group 4: Stander treated with silymarin at a daily dose of 200 mg/kg orally. Group 5: The mice were given 8.4 mg/ kg bw of (PE) orally. Group 6: The mice were given (BPE) extract (140 mg/kg bw) orally. After five consecutive days of treatment, all mice had testis injury in all groups except G1& G2, by a single i.p injection of CCL4 at a dose of 0.5 mL/kg (bw; 20% v/v in corn oil). The result showed a significant increase in luteinizing, follicle-stimulating, and testosterone hormone levels in the serum and semen parameters in the groups treated with PE and BPE. The histological results showed the greatest improvements in testis structures in the BPE group, which was confirmed using (Bcl-2; immunohistochemistry). These results suggest an important role of the antioxidative effects of PE and BPE in the attenuation of CCl4 oxidative stress.

Abstract
Infertility is a prevalent condition affecting approximately 70 million people worldwide and male factor contributes to about fifty percent of the issues. Studies on infectious agents as a possible cause of infertility has become prominent in the past decade. Toxoplasma gondii has emerged as a prime candidate as it has been found in the reproductive organs and semen of males of many animal species and humans. The aim of this study is to assess the effect of latent toxoplasmosis on experimental rat fertility. Ninety Toxoplasma infected rat were used as the experimental group besides, thirty control naïve ones. Both groups were observed clinically. Weekly assessment of fertility indices starting from the 7th week post infection till the 12th week were done by recording rat body weight, weight of testes, semen analysis and histo-morphometric analysis of the testes. Toxoplasma infected rats exhibited significant gradual loss of body weight and the absolute weight of the testes. The sperm characteristic parameters including percentage of motile sperm, percentage of viable sperm and sperm concentration in Toxoplasma infected rats showed highly significant decrease throughout the observation period in comparison to the control group with recording highly significant increase in the percentage of abnormal sperm forms. Pathological insults in tests of the infected rat group were denoted. Our findings demonstrated that Toxoplasma gondii is accused for affecting male rat main reproductive parameters and is implicated in the male reproductive disorders.

Abstract
Busulfan (BUS) is an anticancer agent with serious adverse effects on various body organs, including the lung and testis. Sitagliptin was proven to have antioxidant, anti-inflammatory, antifibrotic, and antiapoptotic effects. This study aims to evaluate whether sitagliptin, a DPP4I, ameliorates BUS-induced pulmonary and testicular injury in rats. Male Wistar rats were split into control, sitagliptin (10 mg/kg), BUS (30 mg/kg), and sitagliptin + BUS groups. Weight change, lung and testis indices, serum testosterone, sperm parameters, markers of oxidative stress [malondialdehyde (MDA) and reduced glutathione (GSH)], inflammation [tumor necrosis factor-alpha (TNF-α)], and relative expression of sirtuin1 (SIRT1) and forkhead box protein type O1 (FOXO1) genes were estimated. Histopathological examination of lung and testicular tissues was done to detect architectural changes [Hematoxylin & Eosin (H&E)], fibrosis (Masson's trichrome), and apoptosis (caspase-3). Sitagliptin treatment reduced body weight loss, lung index, lung and testis MDA, serum TNF-α and sperm abnormal morphology, and increased testis index, lung and testis GSH, serum testosterone, sperm count, viability and motility. SIRT1/FOXO1 balance was restored. Also, sitagliptin attenuated fibrosis and apoptosis in lung and testicular tissues via reducing collagen deposition and caspase-3 expression. Accordingly, sitagliptin ameliorated BUS-induced pulmonary and testicular damage in rats via attenuating oxidative stress, inflammation, fibrosis, and apoptosis.

Abstract
Background Alcohol consumption has a negative effect on male fertility, but Vitamin C may be able to alleviate this effect. Aims In this study, the protective effect of Vitamin C against alcohol-induced testicular damage in adult male Wistar rats was evaluated. Settings and Design This study was conducted in a University setting. Following a 14-day acclimatisation period, forty adult male Wistar rats were randomly divided into eight groups of five rats. The control group received only food and water, test group B received alcohol only, test group C to E received different doses of Vitamin C, test group F to G received different doses of Vitamin C and alcohol. Materials and Methods After a 21-day treatment period, the testis were harvested and analysed for sperm parameters, antioxidant enzyme activity, level of lipid peroxidation and histopathological changes. Statistical Analysis Used All analyses was performed using SPSS (version 16) and Microsoft Excel (2019) using Student's t-test. Results The results showed that in groups administered with alcohol only, there was a decrease in sperm count. Sperm motility, morphology, viability and antioxidant enzyme activity, but increase in the level of lipid peroxidation. In groups treated with Vitamin C and alcohol, there was improvement in the sperm parameters, antioxidant enzymes activity and a decrease and decrease in lipid peroxidation. Furthermore, in the histology of the testis, regenerative changes were seen. Conclusion The chronic consumption of alcohol can have a deleterious effect on the testis, but commercial-grade Vitamin C can reverse these effects.

Abstract
This study aimed to investigate the potential benefits Gum Arabic/Acacia Senegal (GA) in mitigating the harmful effects of cisplatin (CP) on spermatogenesis and testicular health in male adult rats. A total of forty albino rats were used in the study and divided into four groups; control, GA, CP, and Co-treated group, which received both CP and GA concurrently. The results revealed that CP caused a significant increase in oxidative stress and a decrease in antioxidant levels (CAT, SOD, and GSH), which disturbed the testicular machinery. This caused significant histological and ultrastructural damage to the testicular structure, including atrophied seminiferous tubules with severely reduced germinal epithelium. Additionally, CP caused a decrease in reproductive hormones (testosterone and LH), a decline in nucleic proliferation PCNA immunoexpression, and an increase in cytoplasmic apoptotic Caspase-3 protein expression in testicular tissue, when compared to the control and GA groups. Moreover, The CP treatment impaired spermatogenesis and decreased sperm number and motility with abnormal morphology. However, co-administration of GA with CP mitigated the dysfunction in spermatogenesis and reversed testicular damage caused by CP through significantly (P < 0.01) reducing oxidative stress (MDA) and increasing the activities of CAT, SOD, and GSH. Additionally, co-administration of GA elevated the levels of testosterone and luteinizing hormone in blood sera, significantly (P < 0.01) improved the histometric measurements of seminiferous tubules diameter, their epithelial height, Johnsen's score of spermatogenesis, 4-level histological grading scale Cosentino's score, immunohistochemical expression of nucleic PCNA, and cytoplasmic Caspase-3 proteins. Furthermore, TEM examination confirmed the synergistic effect of GA in restoring the germinal epithelial cells ultrastructure, the elongated and transverse sections of spermatozoa in the lumen, and the interstitial tissue. All of these effects resulted in a significant improvement in sperm quality in the Co-treated animals compared with the CP group, as well as, a significant decline in the morphological abnormalities of sperm in Co-treated rats compared to those in the CP group. GA is a valuable agent for ameliorating chemotherapy-related infertility.

Abstract
BACKGROUND The National Toxicology Program (NTP, 1993) reported male reproductive effects in a sodium cyanide (NaCN) drinking water study. The critical effect, decreased cauda epididymis weights, was used by U.S. Environmental Protection Agency for their hazard characterization and risk assessment of hydrogen cyanide and cyanide salts. To further investigate potential male reproductive effects, we conducted a new 90-day drinking water study. METHODS Our study expanded evaluations of testes and thyroid. Male F344 rats received NaCN in drinking water at 0, 0 (water restricted; paired to top dose), 3, 10, 30, 100, and 300 ppm for 13 weeks, followed by 10-weeks recovery. RESULTS Plasma thiocyanate increased dose-dependently but returned to baseline during recovery. NaCN caused neither effects on survival, body weight, food consumption, hematology, serum chemistry, urinalysis, thyroid hormones, testes or epididymides weights, sperm motility/viability, sperm morphology, or sperm production; nor clinical, ophthalmic, or histopathologic findings. Increased organ weights in thyroid/parathyroid and liver occurred at 300-ppm but were recoverable. No changes occurred in male reproductive organs. CONCLUSIONS Absent adverse effects, the NOAEL was 300 ppm (21.66 mg/kg/day; highest dose tested). Based on organ weight increases at 300 ppm, the NOEL was 100 ppm (7.46 mg/kg/day).

Abstract
Trypanotolerance of the West African dwarf (WAD) breeds may not rule out significant pathophysiological changes that may affect productivity. In this study, the effects of infection of WAD rams with Trypanosoma brucei brucei (Tbb) and Trypanosoma congolense (Tc) on their serum levels of electrolytes [calcium, phosphorus, sodium, potassium]; oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA)]; and sperm parameters [sperm count, motility, vitality, and morphology] were investigated. Fifteen WAD rams, assigned to 3 groups (A, B & C) of 5 rams each, were used for the study. Group A rams were infected with Tbb, while Group B rams were infected with Tc, both intraperitoneally, at the dose of 106 trypanosomes/animal. Group C rams served as the uninfected control. The infections were monitored for 70 days. Serum calcium levels were significantly (p < 0.05) lower in Tbb and Tc infected rams compared to the control throughout the study. Serum sodium was significantly (p < 0.05) higher in the Tb infected rams compared to the Tc infected and control rams on days 14 and 28 PI. Serum SOD activity decreased while MDA levels increased in both infected groups of rams. Tbb infected rams were azoospermic, while Tc infected rams had lower sperm motility, vitality and concentration, and higher number of abnormal sperm cells compared to the control. Necrotic and inflammatory lesions occurred in the testis and epididymis of both infected rams. These results suggest that despite trypanotolerance, trypanosome infections in the WAD rams significantly impact on health and reproduction.

Abstract
Betamethasone (BM) is the drug of choice for antenatal corticosteroid therapy for women at risk of preterm delivery because it induces fetal lung maturation and enhances survival after birth. However, our group reported evidence of fetal programming and impaired reproductive development and function in rats exposed during the critical window of genital system development. Therefore, we aimed to investigate the effects of BM on the sexual development of rats in the period that corresponds to antenatal corticosteroid therapy in humans. Male and female rats were exposed subcutaneously to BM at 0.1 μg/g of pups' body weight or to a NaCl 0.9% solution (control) on postnatal days 1-3. It was observed that neonatal exposure to BM decreased body weight and weight gain in male and female rats during treatment. The estrous cycle was deregulated and LH level was decreased in female rats. In male rats, the sperm concentration in the caput-corpus of the epididymis was decreased, whereas the sperm transit time and sperm concentration in the cauda of the epididymis were increased. Our results demonstrated that neonatal exposure to BM impaired body growth of male and female rats, deregulated the estrous cycle of female rats, and altered sperm quality of male rats. Therefore, BM exposure from postnatal days 1 to 3 corroborated results previously observed after prenatal exposure to this drug. Despite the recognized importance of human antenatal corticosteroid therapy, the findings of this study should encourage further studies in order to minimize possible adverse postnatal effects.

Abstract
Local ischemic damage resulting from ovarian torsion is a common cause of decreased follicular activity and infertility. It was aimed to evaluate the effect of granulocyte colony-stimulating factor (G-CSF) protection on in vitro fertilization (IVF) results against experimental ischemic (I) and ischemic-reperfusion (I/R) injury in rat ovaries. The study consisted of 35 adult female Sprague-Dawley albino rats (sham, ischemia, I/R, I + G-CSF, and I/R + G-CSF) randomly assigned to 5 groups, each containing 7 rats. While bilateral adnexal torsion was applied to the ischemia groups for 3 h, detorsion was applied to the reperfusion groups. Intraperitoneal 100 IU/kg G-CSF was administered 30 min prior to ischemia (I + G-CSF) or reperfusion (I/R + G-CSF). After ovulation induction (intraperitoneal 150-300 IU/kg PMSG), the oocytes were collected and IVF was applied. Statistically significant differences were observed between the collected oocyte numbers in I and I + G-CSF, I/R, and I/R + G-CSF groups (P values were P = 0.001 for the I-I + G-SCF groups and P = 0.003 for I/R-IR + G-CSF, respectively). An increase in the number of MII oocytes obtained was observed in the I + G-CSF and I/R + G-CSF groups compared to the I and I/R groups. Grade 1 and grade 2 embryo numbers were statically different between the I/R and I/R + G-CSF groups (P values were P = 0.023 for grade 1 embryos and P = 0.045 for grade 2 embryos, respectively). G-CSF treatment was found to be effective in reducing I- and I/R-induced ovarian damage.

Ranjbarkohan F, Hamedi S. Chronic minocycline administration improves spermatogenesis in rats. Rev Int Androl 2022; 21:100332. [PMID: 36428214 DOI: 10.1016/j.androl.2021.11.003] [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: 02/11/2021] [Revised: 08/30/2021] [Accepted: 11/22/2021] [Indexed: 11/23/2022]
Abstract
INTRODUCTION Minocycline is a tetracycline with promising protective effects on different organs which are completely distinct from its antibacterial effects. METHODS To evaluate the effects of chronic administration of this agent on histological structure and sperm parameters of testes, forty adult male rats were randomly allocated into 2 equal groups I: control animals and II: treated animal that received 25mg/kg/day minocycline, orally. After 90 days of treatment, serum level of testosterone was assessed as well as sperm count, motility and morphology. Moreover, histological and histomorphometric evaluation of testes was performed including determination of height of the seminiferous germinal epithelium and perpendicular diameter of seminiferous tubules. Numbers of spermatogonia, primary spermatocytes, spermatids, Sertoli and Leydig cells were counted. Johnsen's scoring method was also performed. RESULTS Sperm parameters significantly improved in minocycline-treated animals. Moreover, number of germ cells in different stages of development significantly increased in treatment group as compared to control. This finding was associated with better Johnsen's score and thicker epithelium in seminiferous tubules. However, serum testosterone levels, Leydig and Sertoli cell count as well as tubular diameter did not show significant changes (p>0.05). DISCUSSION Chronic administration of minocycline is associated with improved spermatogenesis and sperm characteristics without affecting steroidogenesis in rats.

Abstract
The aim of the study is to investigate the in vivo attenuation of alcohol- and cadmium chloride-induced testicular toxicity modulated by Silymarin in male Wistar rats. A total of fifty-six (56) Wistar rats were used for this study and they were randomized into seven (7) groups of eight (8) rats each. Group 1 was control rats; Groups 2-7 served as the experimental groups. After 6 weeks treatment duration, the rats were euthanized, semen was collected for semen analysis, blood samples for testosterone, and FSH and LH assay determination, and left testes was harvested for histological analysis. One-way ANOVA was used to compare means at p-level < 0.05 was considered significant. Findings from this study have shown that alcohol and cadmium chloride adversely affected semen parameters, testosterone, and FSH and LH hormone milieu. Data also showed that Silymarin administration attenuated the adverse effect of alcohol and cadmium chloride on semen quality and hormones associated with reproductive functions. Hence, Silymarin mopped the effect of in vivo attenuation of alcohol and cadmium chloride testicular damage. The findings of this study have further established that alcohol and cadmium chloride adversely affected semen parameters, testicular alterations, and serum hormonal milieu. However, the effect was more significantly deleterious in rats exposed to cadmium chloride when compared to rats exposed to alcohol, subsequently alcohol- and cadmium chloride-induced degeneration of testicular tissues. Furthermore, Silymarin administration attenuated the adverse effect of alcohol on semen quality and hormones associated with reproductive functions.

Graphical abstract
Abstract The relationship between adolescent ethanol uses and its impacts throughout life are not conclusive. Thus, we evaluated if the low and high consumption of ethanol at postpuberty interferes with the reproduction and ethanol-naive offspring and if the effects are dose-related. Female and male rats were divided into three groups: low drinker (L), high drinker (H) and control (C). The L and H groups were exposed to ethanol up to 10 % from 65 to 80 days with withdrawal after this period. The ethanol consumed by low drinkers was 1.41 ± 0.21 g/kg/day and by high drinkers 4.59 ± 0.45 g/kg/day. The study was conducted in two phases. The first phase verified the reproductive capacity in adulthood on generations (litter size and sex ratio). Data were collected over 10 years. The second phase analyzed the parent reproductive parameters (body weight, reproductive organ weight, sperm parameters and estrous cycle) and the pup development. We observed a reduced litter size in both drinker groups. Gestational body weight gain and feed consumption were lower in L and H. We observed an alteration in reproductive organs weight in both sexes of H. Females presented a longer estrous cycle duration. Males presented an increase in abnormal sperm, a decrease in sperm count and accelerated transit time. The ethanol-naive offspring development was also impaired. We conclude that low and high postpubertal alcohol use impairs long-term reproductive parameters, even after alcohol withdrawal. There is also impaired ethanol-naive offspring. Besides, the effects are dose-related. Lay summary The effects of alcohol use have been reported in several studies. However, better knowledge about early alcohol use and its impact on reproduction in adulthood, after abstinence and on ethanol-naive offspring could help improve preventive measures and mechanisms of action. One of the methods used was retrospective analysis which allows to evaluate the effects of postpubertal ethanol use on the reproductive capacity of rats over generations. Despite our limitations, we verified that the post-adolescent period acts as a susceptibility window, and lifestyle at this age modulates the long-term reproductive parameters. The early ethanol use impairs reproduction function since sperm parameters and the estrous cycle have been altered. The dose of alcohol also contributes to damage on the drinkers’ reproduction and on the physical development of ethanol-naive offspring. Future studies are necessary to identify the mechanism involved in long-term alcohol use effects, even in withdrawal, as well as ethanol-naive offspring outcomes.

Abstract
3-Monochloropropane-1,2-diol (3-MCPD) is a food contaminant formed during acid hydrolysis of vegetable proteins. The toxicological evaluation of smaller doses of 3-MCPD is essential for safety evaluation of this compound. The present study investigates the toxicologic potential of 3-MCPD on male genital organs of rats, applies a correlation between the induced infertility and developed lesions in testes, epididymis, and accessory glands and study the possible mechanisms of 3-MCPD-induced male infertility. Forty rats were randomly divided into four main groups of ten animals each: the control untreated group and three treated groups that were orally administered 3-MCPD at different doses (3, 7.5 and 15 mg/kg b.w) daily via stomach intubation for five successive days per week. Five rats from each group were euthanized after 30 days. The remaining rats were euthanized after 90 days to establish subacute and chronic toxicity studies. Oxidative stress markers, Nrf2 gene expression, semen analysis, and histopathological examination were performed at the end of each experimental period. Results indicated that 3-MCPD induces infertility in male rat via disruption of Nrf2 expression in the testicular tissue with subsequent increased oxidative stress indicators in the testis that affect spermatogenesis and induced testicular degeneration, in addition, induction of epididymal lesions that affect sperm motility and concentration and finally possible development of hyperplastic tissue reactions in accessory glands of intoxicated rats predicting the carcinogenic potential of this compound.

Abstract
CONTEXT Deleterious effects of diabetes on seminal quality, serum metals and antioxidants have been confirmed. OBJECTIVE This study evaluated the effect of combined calcium, magnesium, vitamin C and E supplementation on seminal parameters, serum total antioxidant capacity (TAC), nitric oxide (NO), malonyldialdehyde (MDA), calcium and magnesium in fructose-induced diabetic rats. MATERIALS AND METHODS Thirty rats were grouped into non-diabetic controls, diabetic controls, diabetic rats given vitamin E + C, calcium + magnesium and vitamin E + C + calcium + magnesium. The analytes were evaluated using standard methods. Statistical significance was set at p < .05. RESULTS The diabetic controls had significantly higher MDA (p = .036) but lower (p = .0001) TAC, calcium, magnesium, sperm count, and %motility than the non-diabetic controls. The Vitamin C + E group showed the greatest improvement as they had the highest values of seminal parameters compared to other supplemented groups. CONCLUSION Combined Vitamin C + E supplementation may provide better ameliorative benefits than a combination of Vitamin C, E, calcium and magnesium in diabetics.

Abstract
Varicocele is considered the main reason for male infertility. Antioxidants are common drugs used to reduce the complications of varicocele in these patients. So, we investigated the effects of lycopene on sperm quality, testicular histology, and the expression of some genes in experimentally induced varicocele. Fifty adult male Wistar rats were divided into three groups: control (n = 12), sham (n = 5), and varicocele (n = 33) groups. After 2 months of induced varicocele, five rats were randomly sacrificed and induced varicocele was investigated in each group. Finally, 35 rats were divided into five groups: the control, varicocele, varicocele reserving solvent, and varicocele reserving lycopene (4 and 10 mg/kg) for 2 months. At the end of the experiment, sperm viability, membrane integrity, the expression of Bax, Bcl2, hypoxia (hypoxia‐inducible factor 1α [HIF1‐α]), heat‐shock protein (heat‐shock protein A2 [HSPA2]) genes, and the histology of testes were measured. The results showed a significant decrease in the sperm viability, membrane integrity, Johnson's score, and the expression of the Bcl2 gene in the varicocele group compared to the control group. Also, there was a significant increase in Bax, HSPA2, and HIF1‐α expressions in the varicocele group compared to the control group. Although the administration of lycopene (10 mg/kg) in rats with varicocele improved sperm viability and membrane integrity, Johnson's score, and Bax expression compared to the varicocele group. Our findings indicated that the administration of lycopene in the varicocele group improved sperm quality and testicular injury induced by varicocele via decreasing apoptosis.

Abstract
Anurans have a high reproductive diversity, which is closely associated with testicular dynamics and sperm production. This variety in reproduction is modulated by the sexual characteristics of reproductive strategies, such as polyandry. Leptodactylus podicipinus has high reproductive plasticity, wide geographical distribution, and polyandric behavior. Although aspects of the testes and sperm of this species are known, knowledge about the relationship between these aspects and reproductive investment is scarce. The present study evaluated the morphological characteristics of the testes and sperm in an urban environment. We used 11 sexually mature males from the city of Campo Grande, Mato Grosso do Sul, Brazil. The specimens were obtained from night excursions between April and September; the months that constitute the post-rainy season. The biometric data (snout-vent length, testes, and body mass) were associated with sperm parameters (length of the spermatozoon head and tail). Stereological analyses of sperm morphology and the testes were performed. The results showed correlations between testis mass and spermatozoon length, which were positively related to head length and negatively related to tail length. The locular area and tail length were also negatively correlated. The percentage of normal spermatozoa was 97%; however, some sperm heads and tails exhibited different morphologies from the pattern described for the species. The germinative structure comprised more than 50% of the locular area composed of spermatozoa. The results of this study contribute to the knowledge of aspects related to the reproductive biology of L. podicipinus obtained from an urban environment.

Abstract
OBJECTIVE Ovarian torsion is a common cause of local ischemic damage, reduced follicular activity and infertility. This study aimed to investigate how well platelet-rich plasma (PRP) protects against experimental ischemic (I) and ischemia-reperfusion (I/R) injury in rat ovaries and its effect on in vitro fertilization (IVF) outcomes. METHOD Fifty-six adult female Sprague-Dawley albino rats were randomly assigned to six groups of eight animals each: Sham, Ischemia, I/R, Sham + PRP, I + PRP, and I/R + PRP. The remaining eight animals were used to prepare the PRP. The ischemia groups were subjected to bilateral adnexal torsion for 3 h, while the I/R and I/R + PRP groups received subsequent detorsion for 3 h. Intraperitoneal (i.p.) PRP was administered 30 min prior to ischemia (I + PRP) or reperfusion (I/R + PRP). The ovaries were stimulated through an intraperitoneal injection of 150-300 internal units of IU/kg PMSG. After ovulation induction, oocytes were taken from the ovaries, and IVF was performed. RESULTS The number of MII oocytes reached the highest number with 4.63 ± 0.74 in the S group and had the lowest number with 0.50 ± 0.53 in the I/R group. There were statistically significant differences for the number of embryos obtained on the second day between the I and I + PRP groups and the I/R and I/R + PRP groups (p = 0.000). In comparing anti-Müllerian hormone 1 (AMH1) and AMH2 values within the group, the highest decrease was observed in the I and I/R groups. CONCLUSION PRP is effective in minimizing ovarian damage and preserving ovarian reserves following ovarian torsion.

Abstract
Tamoxifen, a selective non-steroidal estrogen receptor modulator, is the standard adjuvant endocrine treatment for breast cancer. Since information on the risk of using tamoxifen during pregnancy is still scarce, this study evaluated whether the in utero and lactational treatment with this drug could compromise reproductive and behavioural parameters in male offspring. Pregnant Wistar rats were exposed to three doses of tamoxifen (0.12; 0.6; 3 μg/kg), by gavage, from gestational day 15 to lactational day 20. Tamoxifen exposure did not alter the anogenital distance in the male offspring; however, there was a significant increase in the body weight in the 0.12 μg/kg dose and a decrease in the 0.6 μg/kg dose. The male offspring treated with the highest dose exhibited a delay in the onset of puberty, evidenced by an increase in the age of preputial separation. Regarding sperm parameters, there was an increase in the sperm count in the cauda epididymis in the intermediate and highest dose groups, in addition to an increase in the number of static sperm and a decrease in the progressive sperm in the same groups. Moreover, an increase in the number of hyperplasia of the epithelial clear cells was observed in the epididymis. In conclusion, the present study demonstrated that maternal exposure to tamoxifen compromised the installation of puberty of the male offspring and the maturation of the epididymis, affecting sperm storage and motility in the adult life.

Abstract
OBJECTIVE Premature ovarian insufficiency (POI) contributes significantly to female infertility. Cyclophosphamide (CYC has adverse effects on folliculogenesis. Platelet-rich plasma (PRP) is an autologous product rich in many growth factors. We evaluated the protective effect of PRP on in vitro fertilization in female rats with CYC-induced ovarian damage. METHODS Twenty-eight adult female Sprague-Dawley rats were randomly divided into four groups. Group 1 (control-sodium chloride 0.9%; 1 mL/kg, single-dose intraperitoneal [IP] injection); group 2 (CYC), 75 mg/kg, single-dose IP injection and sodium chloride 0.9% (1 mL/kg, single-dose IP injection); group 3 CYC plus PRP, CYC (75 mg/kg, single-dose and PRP (200 μl, single-dose) IP injection); and group 4 (PRP, 200 μl, single-dose IP injection). RESULTS In the comparisons in terms of M1 and M2 oocytes, it was observed that the CYC group presented a significantly lower amount than the control, CYC/PRP, and PRP groups. (for M1, p = 0.000, p = 0.029, p = 0.025; for M2, p = 0.009, p = 0.004, p = 0.000, respectively). The number of fertilized oocytes and two-celled good quality embryos was found to be statistically significant between the CYC and control groups, CYC + PRP and PRP groups (p = 0.009, p = 0.001, p = 0.000 for oocytes, respectively. For embryos; p = 0.016, p = 0.002, p = 0.000). CONCLUSION Platelet-rich plasma can protect the ovarian function against damage caused by CYC, and, in addition, it improves oocyte count and the development of embryos as a result of oocyte stimulation during the IVF procedure.

Abstract
OBJECTIVES Lead exposure seriously impairs male reproductive function. The protective capacity of Pedalium murex leafy stem and fruit aqueous extracts against lead testicular toxicity is evaluated to find herbals drugs able to improve semen quality. METHODS Phytochemical screening were performed according to classical methods. Twenty four male rats were divided into four groups of six rats each and received the following treatments via oral route: distilled water; 0.2% lead acetate in drinking water; 0.2% lead acetate in drinking water with 400 mg/kg P. murex aqueous leafy stem extract; 0.2% leaded water with 400 mg/kg P. murex aqueous fruit extract. Treatments were administered for 70 days. Body and reproductive organs weights, sperm parameters and testicular histological sections of each group were examined. RESULTS Flavonoids, tannins, coumarins, alkaloids, and lignans were found in both extracts. Lead intoxication reduced sperm motility and count but increased the percentage of morphologically abnormal sperms. The germinal epithelium of seminiferous tubules histoarchitecture was disorganized by lead. The leafy stem extract was effective in reducing lead induced testicular disruption whereas fruit has not shown any beneficial effect. CONCLUSIONS P. murex leafy stem aqueous extract is effective against semen alterations caused by lead.

Abstract
A wide variety of environmental chemicals/xenobiotics including bisphenol A (BPA) has been shown to cause male reproductive dysfunctions and infertility. Recently, bisphenol S (BPS) replaces BPA, in several products, including foodstuffs, under the BPA-free label. However, several studies have raised inquietude about the potential adverse effects of BPS. The present study was conducted to evaluate sperm parameters, biochemical parameters, mitochondrial function, and histopathological patterns after post-lactation BPS exposure at a low dose. Male rats (21 days old) were exposed to water containing BPS at 50 μg/L in drinking water for 10 weeks. Results showed no significant alteration in the gonadosomatic index (GSI) and relative reproductive organs weight. However, a significant reduction in epididymal sperm parameters (number, viability, and mobility) with morphological abnormalities were observed in the BPS group compared to control. An increase of malondialdehyde (MDA) level accompanied by antioxidant defense alteration particularly, in glutathione peroxidase activity, as well as a defective mitochondrial function were observed in testicular tissues of BPS treated rats. More importantly, in histopathological diagnosis, BPS treatment induces hypospermatogenesis and alteration in Sertoli cells. In silico docking studies illustrated BPS binds with steroidogenic acute regulatory (StAR) protein thereby affecting the transport of cholesterol into mitochondria resulting in decreased steroidogenesis. These results reflect a reprotoxic effect of BPS vould potentially lead to fertility reduction, in sexually maturity age. We highlighted that post-lactation exposure to BPS, equivalent in humans to the period covering childhood and adolescent stages, disrupt male reproduction function.

Abstract
Oxidative stress (OS) is an important parameter in the evaluation of infertility caused by varicocele. Antioxidants are the most commonly prescribed drugs in these patients. Lycopene molecule, as the powerful antioxidant in the carotenoid family, has beneficial effects on improving fertility in males. Therefore, we investigated the effects of lycopene on induced OS by varicocele in an animal model. Forty-five adult male Wistar rats were divided into two groups: control (n = 12) and varicocele (n = 33). Two months after induced varicocele, five rats in each group were sacrificed randomly and induced varicocele was investigated. Remained rats were divided into five groups (n = 7), including the control (I), varicocele (II), varicocele reserving solvent (III), varicocele reserving lycopene 4 mg/kg (IV), and 10 mg/kg (V) for two months. At the end of the experiment, intracellular reactive oxygen species (ROS), malondialdehyde (MDA), total antioxidant capacity (TAC), %DNA damage, and antioxidant enzymatic levels were measured. The results indicated that there were significant increases in the levels of ROS, MDA, DNA damage, superoxide dismutase (SOD), sperm concentration, and motility in the varicocele groups compared with the control group. In the lycopene group (10 mg/kg), sperm concentration, the levels of TAC, and catalase (CAT) activity were improved so the levels of ROS, MDA, and %DNA damage were reduced compared with varicocele group. Our findings indicated that the administration of lycopene especially at a dose of 10 mg/kg in the varicocele group could protect sperm from OS and sperm DNA damage by increasing antioxidant activity and reducing ROS.

Abstract
At present, one of the main threats to humanity is undoubtedly endocrine disruptors (ED), since they directly disrupt the processes of ensuring homeostasis, which are identical to the very essence of the concept of health, considered in valeology as the ability to maintain age-appropriate stability in conditions of sharp changes in quantitative and qualitative parameters of the triune flow of sensory, verbal and structural information. Pesticides can disrupt the physiological functioning of many endocrine chains, including the endocrine mechanisms that ensure reproductive health. The study aimed to compare the results of our studies of alpha-cypermethrin reproductive toxicity in the test system for studying gonadotoxic activity with data obtained in the test system "Three Generation Reproduction Study". The studies were performed on male and female Wistar Han rats with two generic samples of alpha-cypermethrin from different manufacturers at doses of 0.2, 1.0 and 3.0 mg/kg body weight. The exposure lasted 11 (males) and 10 (females) weeks. During the last two weeks of exposure the state of the estrous cycle, duration and frequency of each stage in females was studied. After the end of treatment functional parameters of the state of the gonads in males and the ability of animals to reproduce were examined. In males, the total sperm count, the absolute and relative number of motile germ cells, and the number of pathologically altered forms were evaluated. The results of the study showed that exposure of male and female Wistar Han rats to alpha-cypermethrin at doses of 0.2–3.0 mg/kg during gametogenesis had a toxic effect on the reproductive system characterized by impaired gonadal and reproductive functions. In our studies, alpha-cypermethrin was found to have reproductive toxicity (reduced number of corpora luteum and live fetuses, increased absolute and relative postimplantation death, reduced average weight of fetuses and litters) and endocrine-disruptive effect, having a pronounced antiandrogenic effect on males. Obvious signs of endocrine reproductive disorders (changes in testis and epididymis weight, deterioration in semen parameters, altered length of separate stages of the estrous cycle) were observed in both females and males. However, studies in a test system of three-generations did not reveal a reproductive and endocrine-disruptive effect of cypermethrin, the toxicity of which was recognized as equivalent to the toxicity of alpha-cypermethrin. The obtained results showed higher sensitivity, informative and diagnostic significance of the methods for studying gonadotoxicity than the methodology of reproductive toxicity studies in the test system “Three Generation Reproduction Study”.

Abstract
Triclosan (TCS) is a phenolic compound with broad-spectrum antimicrobial action that has been incorporated into a variety of personal care products and other industry segments such as toys, textiles, and plastics. Due to its widespread use, TCS and its derivatives have been detected in several environmental compartments, with potential bioaccumulation and persistence. Indeed, some studies have demonstrated that TCS may act as a potential endocrine disruptor for the reproductive system. In the current study, we are reporting on the results obtained for male rats after a two-generation reproduction toxicity study conducted with TCS. Female and male Wistar rats were treated daily by gavage with TCS at doses of 0.8, 2.4, and 8.0 mg/kg/day or corn oil (control group) over 10 weeks (F0) and over 14 weeks (F1) before mating and then throughout mating, until weaning F2 generations, respectively. TCS exposure decreased sperm viability and motility of F1 rats at the dose of 2.4 mg/kg. The effects of TCS on sperm quality may be related to the exposure window, which includes the programming of reproductive cells that occurs during fetal/neonatal development.

Abstract
This study aimed to observe the influence of selenium (Se) deficiency on sperm quality and selenoprotein expression in rats. Four-week male Wista rats were randomly divided into three groups: Se-A, Se-L, and Se-D (respectively for Se- adequate, low, and deficient group). After 9 weeks, the rats were sacrificed by anesthesia, with the cauda epididymidis quickly fetched for sperm count, motility, and deformity. Meanwhile the blood, liver, brain, heart, and testis were collected for Se and biochemical analysis. It was found that the rats in Se-D had poor growth, while the Se concentrations in blood, liver, and heart for Se-D decreased significantly, compared with Se-A and Se-L (p < 0.01). But no significant difference was observed in testis and brain and also no statistical significance for sperm count. The sperm motility for Se-A (63.07%) was significantly higher than Se-L (53.91%) and Se-D (54.15%). Deformities were observed in both Se-L and Se-D. Both glutathione peroxidases (GPxs) and selenoprotein-P (SEPP1) levels in plasma and tissues of Se-D were significantly lower than those of Se-A and Se-L (p < 0.01). The SEPP1 levels in heart and brain of Se-L were lower than Se-A (p < 0.01). There was no statistical difference for GPx1 between Se-A and Se-L. The GPx4 level in testis of Se-L was lower than Se-A (p < 0.05). However, the SEPP1 in plasma, liver, testis, and the GPx3 level in plasma of Se-L were higher than those of Se-A (p < 0.05 or p < 0.01). Our results show that dietary Se deficiency could reduce GPx4 and SEPP1 expression in testis, which further influence sperm motility and may cause sperm deformity. Selenoprotein expression in some tissues of Se-L was higher than that of Se-A, but sperm quality and GPx4 expression in testis were not improved for Se-L. Low active pseudoselenoproteins might be synthesized in low-Se condition. The underlying mechanism needs to be further investigated.

Abstract
Synthetic amorphous silica (SAS) consists of agglomerates and aggregates of primary particles in the nanorange (<100 nm) and it is the E551 authorized food additive. The potential risks for human health associated to dietary exposure to SAS are not completely assessed; in particular, data on male and female reproductive systems are lacking. A 90-day oral toxicity study with pyrogenic SAS nanomaterial NM-203 was carried out on the basis of the OECD test guideline 408 in the frame of the NANoREG project. Adult Sprague-Dawley rats of both sexes were orally treated for 90 days with 0, 2, 5, 10, 20 and 50 mg SAS/kg bw per day. Dose levels were selected to be as close as possible to the expected human exposure to food additive E551. The present paper provides specific information on potential effects on male and female reproductive systems, through the evaluation of serum biomarkers, sperm count, histopathological analysis of testis, epididymis, ovary and uterus and real-time PCR on uterus; potential genotoxic alterations were evaluated by comet assay on testis, sperm and ovary. NM-203 did not induce histophatological and genotoxic effects in male reproductive system. In female rats, ovary is not target of NM-203 and only tissue-specific effects on uterus were recorded up to 10 mg/kg bw per day. To our best knowledge, this is the first study providing data on male and female reproductive systems after long-term, repeated oral exposure at dose levels close to dietary human exposure, which identifies a limited concern only for female reproductive health.

Abstract
There is cumulative evidence that iprodione (IPR) fungicide and chlorpyrifos (CPF) insecticide are endocrine disruptors that can evoke reproductive toxicity. Yet, the underlying mechanisms are still unclear. Besides, the outcomes of their co-exposure to male sexual behavior and male fertility are still unknown. The effects of IPR (200 mg/kg b.wt) and CPF (7.45 mg/kg b.wt) single or mutual exposure for 65 days on sexual behavior, sex hormones, testicular enzymes, testis, and accessory sex gland histomorphometric measurements, apoptosis, and oxidative stress biomarkers were investigated. In addition, expression of nuclear receptor subfamily group A (NR5A1), 17β-hydroxysteroid dehydrogenase (HSD17B3), silent information regulator type-1 (SIRT1), telomerase reverse transcriptase (TERT), and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) genes has been assessed. Our results revealed that the individual or concurrent IPR and CPF exposure significantly disturb the sexual behavior, semen characteristics, testicular enzymes, and male hormones level. Oxidative stress caused by IPR and CPF activates apoptosis by inducing Caspase-3 and reducing Bcl-2. Downregulation of HSD17B3, NR5A1, and SIRT1/TERT/PGC-1α pathway was evident. Of note, most of these disturbances were exaggerated in rats co-exposed to IPR and CPF compared to IPR or CPF alone. Conclusively, our findings verified that IPR and CPF possibly damage the male reproductive system, and concurrent exposure should be avoided.

Deore MS, S K, Naqvi S, Kumar A, Flora SJS. Alpha-Lipoic Acid Protects Co-Exposure to Lead and Zinc Oxide Nanoparticles Induced Neuro, Immuno and Male Reproductive Toxicity in Rats. Front Pharmacol 2021; 12:626238. [PMID: 34305580 PMCID: PMC8296815 DOI: 10.3389/fphar.2021.626238] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Accepted: 05/04/2021] [Indexed: 12/25/2022] Open
Abstract
We evaluated the neuro-, immuno-, and male reproductive toxicity of zinc oxide nanoparticles (ZnO NPs) alone and in combination with lead acetate. We also studied the therapeutic role of α-lipoic acid postexposure. Lead (10 mg/kg, body weight), ZnO NPs (100 mg/kg, bwt) alone, and their combination were administered orally in Wistar rats for 28 days, followed by the administration of α-lipoic acid (15 mg/kg, bwt) for the next 15 days. Our results demonstrated protective effects of α-lipoic acid on lead and ZnO NP-induced biochemical alterations in neurological, immunological, and male reproductive organs in rats. The altered levels of blood δ-aminolevulinic acid dehydratase (ALAD), immunoglobulins (IgA, IgG, IgM, and IgE), interleukins (IL-1β, IL-4, and IL-6), caspase-3, and tumor necrosis factor (TNF-α) were attenuated by lipoic acid treatment. Lead and ZnO NP-induced oxidative stress was decreased by lipoic acid treatment, while a moderate recovery in the normal histoarchitecture of the brain section (cortex and hippocampus) and testes further confirmed the neuro- and male reproductive toxicity of lead and ZnO NPs. We also observed a significant decrease in the blood metal content in the animals treated with lipoic acid compared to the lead-administered group, indicating the moderate chelating property of lipoic acid. It may thus be concluded that lipoic acid might be a promising protective agent against lead and ZnO NP-induced alterations in the neurological, immunological, and reproductive parameters.

Abstract
In this study, we estimated the protective role of Moringa oleifera leaf ethanolic extract (MOLE) against obesity-associated testicular dysfunction. Fifty male albino rats were randomly assigned to five groups (n = 10): Group I (basal diet), group II (basal diet plus MOLE orally), group III (high-fat diet-HFD), group IV (HFD plus oral MOLE) and group V (HFD for 8 weeks followed by a basal diet plus oral MOLE for 6 weeks). The study duration extended for 14 weeks. Serum collected to investigate testosterone, FSH and LH levels. Testicular tissues were used to determine levels of SOD, glutathione, catalase and malondialdehyde. Semen was collected to estimate its quality (morphology, motility and concentration). Morphological changes in the testis were investigated by histopathological and immunohistochemical techniques. Compared with both control treatment and MOLE treatment, serum testosterone, FSH, LH, testicular enzymatic catalase, SOD, GSH, survivin immunoreactivity, sperm quality and testicular weight were all significantly decreased in rats treated with HFD, while there were significant increases in testicular malondialdehyde and caspase-3 immunoreactivity. MOLE improved all harmful effects of HFD. Improvements were more pronounced in the protected (G 4) than the treated (G 5) group. MOLE could be a potential solution for obesity-associated fertility problem.

Abstract
Toxoplasma gondii, as an obligate protozoan parasite, can infect a wide variety of animals as well as human. As some studies have shown, toxoplasmosis decreases the fertility potency in different hosts, so there is a necessity for studies to determine the effects of T. gondii on reproductive system. Therefore, this project was aimed to investigate the effect of toxoplasmosis on the male reproductive system and sperm DNA integrity. In this experimental study, 80 Wistar male rats were divided into two groups as follows: infected group (inoculated by T.gondii tachyzoites) and control group [injected by Phosphate-buffered saline (PBS)]. Afterward, data were collected in every 10 days interval. The detailed description of the sperm parameters were recorded, and then, chromatin integrity of the epididymal sperm was analyzed using Aniline blue (AB), Acridine orange (AO), Chromomycin A3 (CMA3), and Toluidine blue (TB) staining. Sperm parameters (motility, viability, count, and normal sperm) significantly decreased in the infected rats. Sperm stained by AO staining showed a higher percentage in the infected rats compared to the control group on day 70 (P = 0.03). The mean percentages of AB stained sperm on days 30 (P = 0.01) and 50 (P = 0.02) were higher than the healthy group. Also, the significant rising of the stained sperm was observed in the infected group on day 20 (P = 0.01). Sperm stained with TB in the infected group has significantly increased on days 30 to 60 [day 30 (P = 0.001), 40 (P < 0.001), 50 (P = 0.014), and 60 (P = 0.001)]. T. gondii infection leads to the diminished fertility parameters as well as the damaged DNA sperm. The parasite could temporarily interfere with the male reproductive system.

L-carnitine extenuates endocrine disruption, inflammatory burst and oxidative stress in carbendazim-challenged male rats via upregulation of testicular StAR and FABP9, and downregulation of P38-MAPK pathways. Toxicology 2021; 457:152808. [PMID: 33965443 DOI: 10.1016/j.tox.2021.152808] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Revised: 04/23/2021] [Accepted: 05/03/2021] [Indexed: 02/03/2023]
Abstract
We have addressed in the current study the potential of L-carnitine (LC) to extenuate the reproductive toxic insults of carbendazim (CBZ) in male rats, and the molecular mechanisms whereby carnitine would modify the spermatogenic and steroidogenic derangements invoked by the endocrine disruptor. Herein, animals received daily doses of carbendazim (100 mg/kg) by gavage for 8 weeks. Another CBZ-challenged group was co-supplemented with LC (500 mg/kg, IP) twice weekly for 8 weeks. Sperm quantity and quality (morphology, motility and viability), serum testosterone and gonadotropins, and thyroid hormone levels were assessed. Serum tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10) concentrations were determined by ELISA. Oxidant/antioxidant status in rat testis was investigated via measuring testicular contents of malondialdehyde (MDA) and reduced glutathione (GSH), as well as the activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx). Immunohistochemical localizations of the junctional protein; occludin, and inflammatory markers; inducible nitric oxide synthase (iNOS) and nuclear factor kappa beta (NF-κB) were further analyzed. A host of transduction genes that regulate spermatogenic and steroidogenic pathways, and their encoded proteins namely, Steroidogenic Acute Regulatory Protein (StAR), Fatty acid binding protein 9 (FABP9) and P38-mitogen activated protein kinase (P38-MAPK) were assessed by real time quantitative (RT-qPCR) and Western blot. LC improved rat spermiogram, testicular histological alterations and endocrine perturbances, and modulated genes' expressions and their respective proteins. In conclusion, LC effects appear to reside for the most part on its endocrine-preserving, anti-oxidant and anti-inflammatory properties through a myriad of interlaced signal transductions that ultimately recapitulated its beneficial effects on spermatogenesis and steroidogenesis.

Abstract
Studies indicate that rapid weight gain at critical development stages, such as the lactation period, is associated with the development of obesity, cardiovascular diseases, and diabetes in the long term. In addition to metabolic changes during adulthood, overweight/obesity may influence reproductive function. Human and animal studies suggest that lifestyle changes through exercise and/or controlled diet result in improved semen quality in obese individuals. However, the relationship between exercise volume/intensity and reproductive capacity effects remains inconclusive. The present study aimed to evaluate the effects of moderate intensity endurance training and high-intensity interval training (HIIT) on the reproductive parameters of lactating overfed male Wistar rats. Postnatal overfeeding was induced by applying the litter size reduction method. Forty males Wistar rats were used, divided into four groups: one with control litters (CLs) (10 animals/litter-sedentary) and three with small litters (SLs) (4 animals/litter), divided into sedentary, moderate endurance training, and HIIT. Morphologic, metabolic, and reproductive variables were analyzed. SL sedentary group showed increased body weight, adiposity, and decreased relative weight of the seminal vesicle, prostate, and epididymis as well as changes in the insulin tolerance and oral glucose tolerance tests glycemic tests compared to CL sedentary group. Endurance and HIIT protocols were efficient in improving the glycemic metabolism, central fat accumulation of trained groups and did not affect reproductive parameters. Endurance and HIIT protocols proved to be effective in reversing these metabolic changes without impairing the evaluated reproductive parameters.

New approach for reproductive toxicity assessment: chromatoid bodies as a target for methylmercury and polychlorinated biphenyls in prepubertal male rats. Reprod Fertil Dev 2021; 32:914-922.

Abstract
This study investigated the reproductive toxicity of methylmercury (MeHg) and Aroclor (Sigma-Aldrich), alone or in combination, following exposure of prepubertal male rats considering the chromatoid body (CB) as a potential target. The CB is an important molecular regulator of mammalian spermatogenesis, primarily during spermatid cytodifferentiation. Male Wistar rats were exposed to MeHg and/or Aroclor , according the following experimental design: control group, which was administered in corn oil (vehicle) only; MeHg-treated group, which was administered 0.5mg kg-1 day-1 MeHg; Aroclor-treated group, which was administered 1mg kg-1 day-1 Aroclor; Mix-LD, group which was administered a low-dose mixture of MeHg (0.05mg kg-1 day-1) and Aroclor (0.1mg kg-1 day-1); and Mix-HD group, which was administered a high-dose mixture of MeHg (0.5mg kg-1 day-1) and Aroclor (1.0mg kg-1 day-1). MeHg was diluted in distilled water and Aroclor was made up in corn oil (volume 1mL kg-1). Rats were administered the different treatments from PND23 to PND53 by gavage, . The morphophysiology of CBs was analysed, together with aspects of steroid hormones status and regulation, just after the last treatment on PND53. In addition, the long-term effects on sperm parameters were assessed in adult animals. MeHg exposure increased mouse VASA homologue (MVH) protein levels in seminiferous tubules, possibly affecting the epigenetic status of germ cells. Aroclor produced morphological changes to CB assembly, which may explain the observed morphological defects to the sperm flagellum and the consequent decrease in sperm motility. There were no clear additive or synergistic effects between MeHg and Aroclor when administered in combination. In conclusion, this study demonstrates that MeHg and Aroclor have independent deleterious effects on the developing testis, causing molecular and morphological changes in CBs. To the best of our knowledge, this is the first study to show that CBs are targets for toxic agents.

Abstract
Arsenic (As) is an endocrine disrupting chemical that can disturb the male reproductive system. In a previous study, it was suggested that testicular macrophages could display a role in endocrine disruption induced by As exposure. This work aimed to evaluate the effects of chronic As exposure in the testis function of Wistar rats and examine the participation of macrophage activation and inflammatory response in these processes. We examined gene expression of steroidogenic machinery and immunological markers by RT-QPCR, plasma testosterone concentrations, sperm count and morphology, and histomorphometrical parameters after 60-days exposure to 1 or 5 mg.kg-1.day-1 of sodium arsenite, combined or not with 50 μg.kg-1 of LPS administered one day before euthanasia. We have demonstrated that As exposure reduced the weight of androgen-dependent organs and induced changes in spermatogenesis, in particular at the highest dose. LPS and As co-exposure promoted a decrease in testosterone synthesis, but did not increase the overexpression of markers of macrophage activation seen in LPS-only rats. Our results suggest that As does not alter the testicular macrophage function, but under immunological challenges LPS and As can display a complex interaction, which could lead to endocrine disruption.

Abstract
Iodoacetic acid (IAA) is the most genotoxic iodinated disinfection byproduct known in drinking water. Previous studies have shown that IAA may be an endocrine disruptor. However, whether IAA has reproductive and developmental toxicity remains unclear. In this study, the reproductive and developmental toxicity of IAA was evaluated using a battery of in vitro and in vivo reproductive/developmental toxicity screening tests. The results of E-Screen, uterotrophic, and H295R steroidogenesis assays were negative. The Hershberger bioassay revealed that IAA could induce significant increases in absolute and relative weights of paired Cowper's glands. Moreover, there was an increasing trend in the relative weights of the ventral prostate. The micromass test showed that IAA could inhibit the differentiation of midbrain and limb bud cells. A reproductive/developmental toxicity screening test showed that IAA resulted in significantly increased relative weights of testis and seminal vesicles plus coagulating glands in parental male rats, with a dose-response relationship. IAA could not only induce head congestion in offspring but also decrease litter weight, viability index, and anogenital distance index of male pups on postnatal day 4. All these results indicated that IAA had reproductive and developmental toxicity.

Abstract
BACKGROUND Spaceflights-induced microgravity can alter various physiological processes in human's body including the functional status of the reproductive system. Rodent model of tail-suspension hindlimb unloading is extensively used to stimulate the organs responses to the microgravity condition. This study explores the potential effects of hindlimb unloading on testicular functions and spermatogenesis in adult male rats and the underlying mechanism/s. METHODS Twenty Sprague-Dawley rats were allotted into two groups: normally loaded group (control; all arms were in touch with the grid floor) and hindlimb unloaded group (HU; only the forearms were in contact with the grid floor). RESULTS Following 30 days of exposure, the HU group saw a decline in body weight, testicular and epidydimal weights, and all semen parameters. The circulating concentrations of gonadotropin-releasing hormone (GnRH), follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone significantly decreased, while levels of kisspeptin, corticosterone, inhibin, prolactin and estradiol (E2) increased in the HU group. Intratesticular levels of 5α-reductase enzyme and dihydrotestosterone (DHT) were suppressed, while the levels of aromatase and kisspeptin were significantly elevated in the HU group. Hypothalamic kisspeptin (Kiss1) mRNA expression levels were downregulated while its receptors (Kiss1R) were upregulated in the HU group. On the contrary, the mRNA expression levels of testicular Kiss1 were upregulated while Kiss1R were downregulated. The pituitary mRNA expression levels of FSHβ and LHβ decreased in the HU group. The levels of the antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and nitric oxide (NO) concentrations, and total antioxidant capacity (TAC) were elevated while malondialdehyde (MDA) concentrations declined in the testes of HU group. The testes of the HU rats showed positive immunostaining of caspase-3, heat shock protein 70 (HSP70) and Bcl2. CONCLUSIONS Altogether, these results revealed an inhibitory effect of hindlimb unloading on kisspeptin signaling in the hypothalamic-pituitary-testicular axis with impaired spermatogenesis and steroidogenesis.
