AI Article Synopsis
- Arsenic is a natural metalloid widely present in the environment, primarily affecting health through contaminated drinking water.
- Exposure to arsenic can lead to multiple reproductive issues in males, including decreased testosterone levels and impaired sperm quality.
- The review highlights various mechanisms of arsenic-induced male reproductive toxicity, such as oxidative stress and inhibition of spermatogenesis, and calls for more research to better understand these complex interactions.
Article Abstract
Arsenic is a natural metalloid found in abundance, in the environment. Exposure to arsenic can cause health issues due to its carcinogenic nature. The primary source of arsenic contact is drinking water. Exposure to arsenic in drinking water can cause reproductive dysfunction in males through a reduction in testes weight, accessory sex organ weight, viability, and motility of sperm, epididymal sperm count, decreased gonadotrophins level, decreased testosterone, and steroidogenesis disruption. This review focuses on the mechanisms by which arsenic impairs the quality of semen, based on epidemiological observations in humans, and experimental studies in different biological research models. Arsenic-mediated male reproductive toxicity can be induced by various mechanisms such as inhibition of spermatogenesis, testosterone pathway hinderance, oxidative stress, inflammation, genotoxic effects, activation of heat shock proteins, and activation of a signaling pathway in testes (ERK/AKT/NF-kB signaling pathway), among others. The interplay between the principal mechanisms involved needs to be elucidated further in future since an overall examination of arsenic-mediated male reproductive toxicity is still a deficit.

Severe toxic effects of arsenic on human physiology have been of immense concern worldwide. Arsenic causes irrevocable structural and functional disruption of tissues, leading to major diseases in chronically exposed individuals. However, it is yet to be resolved whether the effects result from direct deposition and persistence of arsenic in tissues, or via activation of indirect signaling components.

Inorganic arsenic (iAs)-induced urothelial carcinoma (UC) develops into a poor-prognosis malignancy. Arsenic-induced oxidative stress contributes to circadian rhythm disruption altered metabolism. Glutamine anaplerosis is a common metabolic feature of rapidly proliferating malignant cells, in which glutaminase (GLS) is a key enzyme in this process.

Epidemiological evidence reveals that arsenic increases the risk of chronic kidney disease (CKD) in humans, but its mechanism of action has so far been unclear. Fibrosis is the manifestation of end-stage renal disease. Hypoxia is recognized as a vital event accompanying the progression of renal fibrosis.

Developmental exposure to environmental pollutants has been shown to promote adverse health outcomes in offspring. Exposure to heavy metals such as arsenic which also has endocrine-disrupting activity is being increasingly linked with cancers, diabetes, and lately with Metabolic Syndrome (MetS). In this work, we have assessed the effects of preconceptional plus gestational arsenic exposure on the developmental programming of MetS in offspring.

Demyelination is the loss of myelin in CNS, resulting in damaged myelin sheath. Oxidative stress and neuroinflammation play a key role in inducing demyelinating diseases like MS; hence, controlling oxidative stress and neuroinflammation is important. Cuprizone (CPZ), a copper chelator, generates oxidative stress and neuroinflammation, thereby inducing demyelination.
