In recent years, fluorosis caused many problems in humans and animals bodies. Dental fluorosis, skeletal fluorosis, bone fractures, decreased birth rates, adverse effects on the male genital system, like damaging the structure of testes and epididymis and loosing fertilization ability can be considered as good examples of fluorosis. Thus, the current study aimed to determine the toxicity of sodium fluoride (NaF) on the activity of sperm and the level of sex hormones including testosterone, follicle stimulating hormone, and luteinizing hormone. For achieving this purpose, thirty adult albino male rats, aged between 90-100 days, were divided randomly into two treated groups with 10 rats for each group which were treated with 150, 300 ppm of sodium fluoride,respectively. In addition, 10 rats were kept as a control group. Sodium fluoride was offered to the treated groups in the drinking water to evaluate the toxic effect of NaF on male reproductive system, sperm concentration, sperm motion, and sperm velocity compared with control group. The findings revealed a significant decrease in the sperm concentration, sperm count, sperm motion, sperm velocity and the level of sexual hormones in comparison with the control group. It can be concluded that NaF may reduce the efficiency of male reproductive system, and reduce the levels of sexual hormones in rats

Cadmium (Cd) is a heavy metal that is widely present in modern industrial production. It is a known, highly toxic environmental endocrine disruptor. Long-term exposure to Cd can cause varying degrees of damage to the liver, kidney, and reproductive system of organisms, especially the male reproductive system. This study aimed to explore the mechanism of Cd toxicity in the male reproductive system during puberty. Eighteen healthy 6-week-old male Sprague–Dawley rats were randomly divided into three groups (control group, low-dose group, and high-dose group) according to their body weight, with six in each group. Cd (0, 1, and 3 mg/kg/day) was given by gavage for 28 consecutive days. The results showed that Cd exposure to each dose group caused a decrease in the testicular organ coefficient and sperm count, compared with the control group. Cd exposure resulted in significant changes in testicular morphology in the 3 mg/kg/day Cd group. In the 1 and 3 mg/kg/day Cd groups, serum testosterone decreased and apoptosis of testicular cells increased significantly ( p < 0.05). In addition, compared with the control group, the activity of glutathione peroxidase and superoxide dismutase in each Cd exposure dose group decreased, but the content of malondialdehyde in the high-dose, 3 mg/kg/day Cd treatment group significantly increased ( p < 0.05). Although Cd exposure caused an increase in the messenger RNA (mRNA) levels of Bcl-2, Caspase-3 and Caspase-9 in the testicular tissues ( p < 0.05), Bcl-2 expression was unchanged ( p > 0.05). The expression level of Akt mRNA in testicular tissue of rats in the high-dose 3 mg/kg/day Cd group was increased ( p < 0.05). Our data suggest that Cd affected testosterone levels, and apoptosis was observed in spermatids.

Background: Ischemic/reperfusion (I/R) in testicular tissue is one reason for the worldwide increase in male infertility. In the present study, we assessed the effects of curcumin and Fe3O4 nanoparticles (NPs) on sperm parameters in rats with I/R damage. Materials and Methods: Forty-eight adult male rats were divided into two groups (n=24 per group): control and torsion/detorsion. The control and torsion/detorsion groups were divided into four subgroups include sham, Fe3O4 NPs, curcumin, and Fe3O4 NPs+curcumin. After the rats were sacrificed, semen was collected from their epididymal tissues to assess sperm viability, motility, concentration, and morphology. Results: Curcumin significantly improved viability, motility, and normal sperm morphology in rats with I/R damage compared to the control group; however, it did not have a significant effect on sperm concentration (P<0.001). Fe3O4 NPs alone decreased all sperm parameters in the control and I/R rats (P<0.001). However, concomitant administration of Fe3O4 nanoparticles with curcumin significantly improved sperm parameters in rats with I/R damage (P<0.001). Conclusion: The increase in all semen parameters in the experimental groups with concomitant use of Fe3O4 NPs plus curcumin indicated that green synthesis of NPs could be recommended for future clinical studies.

Abstract Background: Sex hormones may be associated with a higher incidence of ischemic stroke or stroke-related events. In observational studies, lower testosterone concentrations are associated with infirmity, vascular disease, and adverse cardiovascular risk factors. Currently, female sexual hormones are considered neuroprotective agents. The purpose of this study was to assess the role of sex hormones and the ratio of estradiol/testosterone (E/T) in patients with acute ischemic stroke (AIS).Methods: Between January 2011 and December 2016, 146 male patients with AIS and 152 age- and sex-matched control subjects were included in this study. Sex hormones, including estradiol, progesterone, and testosterone, were evaluated in the AIS patient and control groups. We analyzed the clinical and physiological levels of sex hormones and hormone ratios in these patients.Results: The E/T ratio was significantly elevated among patients in the stroke group compared to those in the control group (P = 0.001). Categorization of data into tertiles revealed that patients with the highest E/T ratio were more likely to have AIS [odds ratio (OR) 3.084; 95% Confidence interval (CI): 1.616-5.886; P < 0.001) compared with those in the first tertile. The E/T ratio was also an independent unfavorable outcome predictor with an adjusted OR of 1.167 (95% CI: 1.053-1.294; P = 0.003).Conclusions: These findings support the hypothesis that increased estradiol and reduced testosterone levels are associated with AIS in men.

     The present study was undertaken to evaluate the effect of aqueous extract of Date Palm Pollen DPP on the testicular function and serum testosterone, FSH and LH hormones value. Thirty five male rats were divided randomly into five equal groups. Group 1: received 0.5 ml of distilled water (control group), group 2: was treated orally 0.250 p.p.m of sodium florid (NaF) (with volume of 0.5 ml / rat), Group 3: was treated with 0.250 p.p.m of NaF and 50 mg/kg. B.W. of DPP extract (0.5ml D.W \rat), Group 4: was treated with 0.250 p.p.m of NaF and 100 mg/kg. B.W. of DPP extract and Group 5: was treated with 0.250 p.p.m of NaF and 150 mg/kg. B.W. of DPP extract. The results showed  significant (P< 0.05) decrease in sperm concentration, motility and significant (P< 0.05) increases in dead and abnormal sperm in the group 2 in comparison to control, while all groups of  DPP extract showed significant (P< 0.05) increase in  sperm concentration, motility and decrease in dead and abnormal sperm. Maximum effect was observed in animals treated with a dose of 150 mg/kg of DPP extract, also the results revealed significant (P< 0.05) increase in testosterone, FSH and LH hormones in groups treated with DDP in comparison to G1andG2. Male rats received DPP for 50 days showed significant (P< 0.05) increases in body and testes weight as compared to G1andG2. In conclusion the results revealed that the aqueous extract of DPP pollen can be used as a sex enhancer and seems to cure male infertility.

Background: The oleo-gum-resin of Commiphora myrrha (myrrh) has a long history of therapeutic use in traditional medicine. The aim of this study was to seek for the scientific evidence to determine whether the ethanolic extract of myrrh (EEM) has any beneficial effects on Streptozotocin (STZ) induced testicular impairments, and explore the possible mechanisms underlying such actions. Methods: Forty-eight severe and complicated diabetic rats (fasting blood glucose above 350 mg/dL), randomly were divided into six equal groups (n=8). Besides, eight healthy rats allocated as a normal control group and only treated with vehicle solution. The diabetic animals orally received the extract (100, 200, 300, and 500 mg/kg), metformin (500 mg/kg) or vehicle solution for 28 days. As a final point, plasma glucose and insulin, circulatory sex hormones, sperm parameters including sperm concentration, motility and viability and also testicular malondialdehyde (MDA) levels were assessed. Furthermore, quantitative histological evaluation of seminiferous tubules area and determination of germinal cells apoptosis were performed. Results: None of the studied doses of EEM showed anti-diabetic effects. However, the extract mainly at the maximum dose (500 mg/kg) exhibited beneficial effects on reproductive impairments. The EEM treated rats mainly at 500 mg/kg had significantly higher sperm concentration, sperm motility, sperm viability, sex hormones and lower testicular MDA and germ cell apoptosis index than untreated diabetic rats. Conclusion: These results indicated that EEM may have beneficial effects against reproductive dysfunction induced by diabetes. The mechanisms behind the effects might be associated with the EEM sex hormone booster potential, antioxidant and anti-apoptotic properties.

In this research, we analyzed the effect of an intragastrical oral administration of red-fleshed apple anthocyanin extract (RAAE) on busulfan-treated mice. First, we showed that the most abundant component in RAAE was cyanidin 3-O-galactoside. To determine the effect of the RAAE, the mice were divided into control and four other different concentrations of RAAE feeding treatment groups (BA0, no RAAE; BA.1, 0.1 mg/kg; BA1, 1 mg/kg; and BA5, 5 mg/kg) following busulfan injection. We observed that RAAE treatments displayed ameliorative effects on male reproductive system dysfunction caused by busulfan, such as recovering the irregular arrangements of seminiferous tubules, increasing the number of spermatogonia and spermatocytes, improving sperm concentration by 3-fold in BA.1, and improving sperm motility by 2-fold in BA1. The liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis showed significant up- or downregulation of certain metabolites, such as lysophosphatidylcholine (LysoPC), L-arginine, glycine, anandamide, and L-carnitine, which could contribute to the positive effects of RAAE, especially in PBA1 (plasma of BA1) and PBA5 (plasma of BA5). Taken together, the results indicate that 1 mg/kg of RAAE is a suitable concentration for rescuing spermatogenesis in mice. The research suggests that RAAE could be a potential nutraceutical for protecting spermatogenesis after busulfan therapy in cancer.

Abstract text Since the very early days of the COVID-19 pandemic, concern has been raised about the possibility of damage to the male reproductive system in those men who are infected with SARS-CoV-2. This was first raised by the early observation (January 2020) that the route of infection was via the Angiotensin Converting Enzyme 2 (ACE-2) receptor present on host cells. ACE-2 was first described in the year 2000 and subsequently shown in 2004 to be selectively expressed in the Leydig cells of the adult testis. This opens up the possibility that although COVID-19 is primarily a respiratory infection, it may also infect the male reproductive system. The authors of several review articles have proposed that male fertility may be theoretically impacted by SARS-CoV-2 in a number of ways. This includes alteration of: (i) testicular architecture; (ii) reproductive hormone profiles (LH/FSH); (iii) spermatogenesis as evidenced by changes to ejaculate quality; (iv) sperm function (e.g., DNA damage); (v) sexual/erectile function; or a combination of all five. Clearly each of these individually may impact on the chance of pregnancy or live birth either in natural or medically assisted reproduction. There is also the possibility that SARS-CoV-2 may be transmitted sexually if sufficient numbers of SARS-CoV-2 are found in semen. Reassuringly, of 14 studies published to date, there is little evidence to suggest that SARS-CoV-2 is present in semen and so the possibility of sexual transmission in patient or donor samples can probably be discounted. However, there is currently an incomplete picture of whether semen quality is affected by SARS-CoV-2 infection as studies are often limited by the fact that no pre-infection control samples are available for direct comparison or they are too short to identify any long-term effects. Nevertheless, the few case-controlled studies published which compare semen quality infected with non-infected (control) individuals suggest that there may be a statistically significant alteration in sperm concentration and motility, although it is not clear whether this is linked to infection by the SARS-CoV-2 virus or simply a consequence of febrile illness and fever (or medication given to combat the infection). There is currently a lack of long-term data on any impact of COVID-19 on male reproductive hormones (although much speculation about the role that testosterone might play in the severity of disease). There are also emerging reports of increased risk of erectile dysfunction in men following SARS-CoV-2. In terms of birth rates, it is simply too early to tell whether these have been affected by the pandemic, given the possibility of lockdown affecting sexual behaviour in fertile couples and IVF clinic closures in infertile couples. In conclusion, although the COVID-19 pandemic has infected over 130 million people worldwide we still know too little about the impact of SARS-CoV-2 on the male reproductive system. Given the incidence of long-COVID, and the asymptomatic nature of the infection for some, it is important to commission and conduct long-term studies which can monitor the reproductive outcomes of young men who have survived a SARS-CoV-2 infection.

The present study was aimed to investigate the possible effects caused by the antibiotic, metronidazole, on the histology of the testis and the morphology of the sperms of mice. To achieve this,  adult male albino Swiss Mice were orally administrated with 0.1 ml (100 mg\ kg ) of the commercially used metronidazole (Flagyl) for 60 consecutive days. The results showed significant decreases (p<0.05) in the mean weight of body and testis in the treated mice as compared to the distilled water-treated control group. The treatment also caused several histopathological changes in the testis which included necrosis, congestion, hemorrhage, edema, germ cell downfall  and rupture in the seminiferous tubules. The tests of the sperm morphology revealed a number of deformations as a result of the treatment, such as the appearance of headless,  bend, broken-tailed, hook-tailed, and two-headed sperms, as well as sperms with cytoplasmic droplets. We conclude that from these results that orally administered Metronidazole exerts negative effects on the male reproductive system of mice .

Abstract Background: The novel beta-coronavirus disease (COVID-19) has infected millions of people globally with high risk among male then female. However, the effect of COVID-19 andrology is still a subject of dispute. We planned to analyze the overall consequences of COVID-19 on semen parameters and male sex hormones.Main text: Systematic search was performed on MEDLINE and Scopus database until June 11 2021. We included observational studies, which reported mean ± standard deviation of the semen parameters and serum sex hormones of those reproductive-aged male recovered from COVID-19 and controls who did not suffered from COVID-19. We used Random-effect model to pool the studies, as heterogeneity was present. Heterogeneity was evaluated by Q test and I2. All studies were assessed with their quality and publication bias.We assessed 966 articles for eligibility and found 7 eligible studies meeting PICO criteria. This include 934 participants with mean age 37.34 ± 10.5. Random-effect model meta-analysis showed that men recovered form COVID-19 had semen parameters less than those who had not suffered from COVID-19. The overall mean difference (MD) [95% confidence interval (CI)] in semen volume, sperm concentration, sperm number, and progressive sperm motility was -0.20 (-0.45, 0.05), -16.59 (-34.82, 1.65), -45.44 (-84.56, -6.31), -1.73(-8.20, 4.75) respectively. Considering sex hormones; Luteinizing hormone and prolactin was found more among those recovered with the significant MD (95% CI) of 3.47 (1.59, 5.35) and 3.21 (1.71, 4.72) respectively.Conclusion: Both the semen parameters and sexual hormones were found to be affected after infected with COVID-19. However, the mechanism for testicular involvement remains doubtful.This systematic review and meta-analysis has been registered in PROSPERO (ID: CRD42021259445)
