In occupational settings, incidents such as the Minamata and Niigata disease in Japan and the large-scale methylmercury poisoning in Iraq have highlighted the severe health impacts of mercury exposure. It is widely accepted that all forms of mercury including methylmercury and mercuric chloride have the potential to induce toxic effects in mammals, and there is increasing concern about the impact of environmentally relevant levels of mercury on reproductive functions. This review summarizes current knowledge on the mechanisms of mercury toxicity, focusing specifically on its impact on male reproductive health across species. We searched the literature and found that mercury exposure is associated with testicular degeneration, altered spermatogenesis, and Leydig cell deformation. In addition, mercury can disrupt sperm motility, steroidogenesis and interfere with the hypothalamic-pituitary-gonadal axis by generation of reactive oxygen species, inducing mitochondrial dysfunction, epigenetic changes, and DNA damage. At the molecular level, mercury has been found to dysregulate the expression of key steroidogenic and spermatogenic genes, significantly reducing overall fertility potential. However, specific mechanisms of action remain to be fully elucidated. Similarly, comprehensive data on the potential transgenerational effects of paternal mercury exposure are lacking. In this review, we discuss both animal and human studies, and highlight the need for further research due to lack of standardization and control for variables such as lifestyle, immune system function, and exposure concentrations.</div></div>","PeriodicalId":49970,"journal":{"name":"Journal of Trace Elements in Medicine and Biology","volume":"87 ","pages":"Article 127598"},"PeriodicalIF":3.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143018959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scientific studies have validated its traditional uses in folk medicine, highlighting its pharmacological activities. Alzheimer's Disease (AD) is a neurodegenerative disorder marked by the buildup of amyloid-β (Aβ) plaques and neurofibrillary tangles (NFT) in the brain, leading to synaptic impairment and the gradual loss of neurons. Currently, no effective medication is available to treat the development and progression of the disease. Hence, there is a rising concern about using alternative therapy such as herbal medicine to limit the progression of AD and improve the quality of a patient’s life with minimum side effects. The plant <em>Cuscuta reflexa</em> has traditionally been claimed to possess neuroprotective effects but has not yet been validated scientifically.

The goals of this study were to measure metal contamination in various fish species from the Lower Mississippi River Basin, evaluate the human consumption risk, and estimate bioindicator potential of these species for monitoring toxic metals on a larger scale. Various fish species (n = 203) were analyzed for 15 metal contaminants (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Ni, Pb, Se, and Zn).

Non-cancerous health hazard assessments indicated blue catfish, flathead catfish, gar species, and freshwater drum as species of concern. Consumption of all species posed human cancer risks. Computational modeling, with an accuracy of 98.5 %, identified Hg, Pb, Zn, Cr, Co, As, and Cd as major drivers of fish consumption safety. Using bioaccumulation factor analysis, we estimated the bioindicator potential of toxic metals for each fish species, finding Hg and Cd to be greatly bioaccumulative in predatory gar species.
