This review discusses the multifactorial aspects contributing to male infertility, focusing on oxidative stress (OS), sperm quality, gut microbiota, and the potential role of adaptogens. A comprehensive literature search was conducted across several major databases, including the Cochrane Library, Medline, Embase, SciSearch, PubMed, Web of Science, Scopus, and Google Scholar. The findings from the studies included in the databases highlight the significant role of oxidative stress in male infertility, with reactive oxygen species (ROS) contributing to sperm DNA fragmentation and impairment of spermatogenesis. The review further elucidates the influence of both endogenous and exogenous sources of ROS, including lifestyle factors and environmental exposures, on male reproductive health. Emerging research also highlights the involvement of key molecular pathways, such as Nrf2, AMPK/PGC-1α, and NF-κB, in regulating OS within the male reproductive system. Additionally, the review outlines the relationship between endothelial dysfunction, cardiovascular health, and male infertility, identifying OS as a common underlying factor. In addition to the OS, the gut microbiota has been identified as a pivotal factor in male fertility, influencing inflammation and hormonal regulation. This review underscores the potential merits of a synergistic strategy that integrates dietary interventions, antioxidants, gut microbiota modulation, and adaptogens to enhance fertility outcomes. Adaptogens, recognised for their capacity to assist the body in coping with stress and re-establishing equilibrium, may confer protective effects against OS and improve reproductive health. The review under discussion emphasises the importance of a holistic approach to male infertility, integrating molecular, clinical, and lifestyle factors to optimise reproductive health.</p>","PeriodicalId":9845,"journal":{"name":"Cellular Physiology and Biochemistry","volume":"59 S2","pages":"82-123"},"PeriodicalIF":2.0,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144944953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dependencies analyzed here in this area have not been studied using such an approach so far. Therefore, they are innovative and constitute an important aspect of multi-range interdependencies. That is why we analyzed factors shaping male reproductive condition: glutathione, bilirubin, uric acid, chemical elements (Ca, Na, Mn, Fe, Mo, Li, V, Co, Ag, Ba, Tl, Al, Ni, Sn, B, Pb, Be), and genetic polymorphism (genotypes CC and TT of IL-4v.C589T(rs2243250).

The population of patients with infertility consisted of 76 men with different fertility disorders. The control group consisted of 87 men with normozoospermia. The majority of infertile men came from Central Poland. The collection of biological samples and seminological tests were conducted by qualified medicians from the andrology clinic and by the authors of this paper (semen morphological parameters). Seminological analyses were based on macro- and microscopic analysis of ejaculate to verify semen volume, time of liquefaction, sperm density, motility, presence of agglutination, presence of leukocytes, and percentage of pathological forms. Concentrations of chemical elements in the blood were analyzed (ICP-MS). In serum, non-enzymatic antioxidants (glutathione GSH, bilirubin, uric acid) and lipid peroxidation intensity were qualified (Cayman Chemicals Co.). In researching gene polymorphisms connected with male infertility, molecular analysis was conducted (PCR-RFLP) and applied to chromosome 5: gene IL-4v.C589T.</p><p><strong>Results: </strong>We found poorer antioxidative defense in infertile men, whilst the higher levels of uric acid, compared to healthy, may act as a deteriorating factor. High correlations between glutathione and uric acid in the infertile and healthy implicated that non-enzymatic antioxidants undergo mutual regulation. It also applies to patients with IL-4v.C589T polymorphism. Interactions between non-enzymatic antioxidants and chemical elements were particularly noticeable in men with CC genotype. The most important modulator appeared to be sodium, while boron was the most meaningful in the interactions. Higher concentration of bilirubin, uric acid, and GSH in men with TT (0.687 mg·dL-1, 6.097 mg·dL-1, 6.345 µM), compared to CC genotype (0.652 mg·dL-1, 4.980 mg·dL-1, 4.630 µM) suggest a better functionality of antioxidative barrier.

These changes contribute to various adverse physiological effects, including systemic inflammation, mitochondrial dysfunction, and intestinal barrier dysfunction. This review provides a comprehensive analysis of the molecular mechanisms by which these environmental factors induce oxidative damage, emphasising the importance of redox imbalance, the overproduction of reactive oxygen species, and inflammatory signalling pathways. Key pathways involved include NF-κB, Nrf2/Keap1, PI3K/AKT, p38-MAPK, JAK/STAT and TLR4/MyD88. These pathways collectively contribute to the progression of chronic inflammatory conditions. Furthermore, this article synthesises findings from 354 studies published between 2016 and 2024, integrating human and animal research evidence. Existing literature suggests that gut dysbiosis exacerbates oxidative stress through impaired short-chain fatty acid production, downregulation of peroxisome proliferator-activated receptor gamma, and disruption of antioxidant enzyme activity. This review explores these mechanisms in more detail. Additionally, the review evaluates studies investigating microbiota-targeted therapeutic interventions to mitigate oxidative stress. These interventions include probiotics, prebiotics, polyphenols, and postbiotics, focusing on their reported modulation of Nrf2 and AMPK signalling pathways. The potential of faecal microbiota transplantation as an innovative approach to restoring a healthy gut ecosystem and counteracting pollutant-induced oxidative damage is also discussed. In light of the growing global exposure to environmental pollutants and their associated long-term health implications, it is imperative to gain a deeper understanding of their impact on gut microbiota and oxidative stress.

It exists as a membrane-bound protein or as a soluble factor. Membrane-bound αKlotho is an essential cofactor for fibroblast growth factor 23 (FGF23), thereby being involved in the regulation of renal phosphate and vitamin D metabolism. Soluble αKlotho (sKL) is present in different body fluids and exerts hormone-like effects. Through the αKlotho-FGF23 signaling axis, FGF23 regulates phosphate excretion by downregulating Na+-dependent phosphate transporter (NaPi-2a). In addition, this axis suppresses expression of 1α-hydroxylase, thereby reducing active vitamin D (calcitriol) serum concentration. Disruptions of this axis lead to deranged mineral metabolism. Low levels of αKlotho and elevated FGF23 are early biomarkers for different diseases, including chronic kidney disease (CKD) and cardiovascular diseases (CVD). In CKD, decreased renal αKlotho expression and enhanced FGF23 production contribute to worsening kidney function. Activated transforming growth factor b1 (TGF-b1) signaling, promoting renal fibrosis, contributes to the pathophysiology. Moreover, FGF23 directly induces left ventricular hypertrophy (LVH) through FGF receptor-induced calcineurin/nuclear factor of activated T cells (NFAT) signaling in CKD.
