Global male reproductive health has been deteriorating due to a combination of genetic, environmental, and lifestyle factors, including oxidative stress, reactive oxygen species (ROS), epigenetic alterations, and posttranslational modifications (PTMs). Ferroptosis is characterized by iron overload and lipid peroxidation, leading to testicular damage and impaired spermatogenesis, thus contributing to male infertility. While iron plays an essential role in maintaining spermatogenesis and testosterone production, its overload induces oxidative stress, ROS accumulation, and testicular ferroptosis, which disrupts normal reproductive function. Factors such as failure of antioxidant defense systems, exposure to xenobiotics (e.g., arsenite, cadmium, phthalates, bisphenol A, PM2.5), and alterations in ferroptosis-related genes (FRGs) further exacerbate testicular dysfunction. This review examines the critical role of lipid, iron, and glutathione metabolic pathways in ferroptosis induction, the effects of environmental xenobiotics on testicular health, and the potential therapeutic benefits of ferroptosis inhibitors in treating male infertility.</div></div>","PeriodicalId":21137,"journal":{"name":"Reproductive toxicology","volume":"137 ","pages":"Article 109022"},"PeriodicalIF":2.8,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144765342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, our objective was to establish evidence for association between folate deficiency, hormone dynamics, and ovarian function using in vivo model. Folate-deprived female zebrafish were developed using intraperitoneal administration of methotrexate (MTX; DHFR inhibitor) and were used to study the possible implications of folate deprivation on ovarian health. Changes in the expression of transcripts regulating appetite and ovarian function was observed. We observed that folate deprivation resulted in impaired appetite behaviour and alteration in its regulatory gene expression. Due to folate deficiency, the neuroendocrine function of the brain was affected that resulted in altered reproductive hormone levels. Histology of ovary shows follicles arrested in primary oocyte stage and scarring of tissue is seen. Furthermore, elevated lipid peroxidation and catalase enzyme activity along with increased IL-6, indicates folate deficiency induced oxidative stress and inflammation in ovary as one of the possible mechanisms to aid- ovarian dysfunction. Our study provides experimental evidence, using an in vivo folate-deficient fish model, that underscores the essential role of folate in maintaining reproductive health.
