Epigenetic rescue of the male germline: Plant-derived bioactive compounds as modulators of transgenerational reproductive risks induced by bisphenols and microplastics
AI summary Read the abstract
This review pulls together existing lab research suggesting that everyday exposure to bisphenols (like BPA) and microplastics may damage sperm not just by harming fertility directly, but by altering chemical "tags" on DNA that can potentially be passed down to future generations. Encouragingly, the researchers found early evidence that certain plant compounds—found in foods like fruits, vegetables, and herbs—might help reverse some of this damage by protecting sperm cells and restoring healthy DNA patterns. It's important to note this is still mostly animal and lab-based research, not yet proven in humans, but it opens the door to future pr
This interpretive narrative review examines whether plant-derived bioactive compounds can modulate male germline epigenetic disruption induced by bisphenols and micro- and nanoplastics (MNPs), with emphasis on transgenerational reproductive risk within the Developmental Origins of Health and Disease (DOHaD) framework. We synthesized mechanistic and experimental literature on bisphenol- and MNP-induced reproductive toxicity, sperm epigenetic regulation, and phytochemical-based intervention strategies. The evidence indicates that plastic-associated contaminants impair steroidogenesis, blood-testis barrier integrity, redox homeostasis, chromatin regulation, and sperm epigenetic programming. Conversely, selected phytochemicals may counteract these effects through modulation of epigenetic pathways, mitochondrial stabilization, and anti-inflammatory signaling. Based on the available evidence, we propose an operational framework for defining germline epigenetic rescue, requiring recovery of reproductive function together with normalization of at least one germline epigenetic layer. Although current evidence remains predominantly preclinical, the concept of epigenetic rescue provides a biologically plausible and testable framework for moving beyond damage description toward prevention-oriented strategies in reproductive toxicology.

Reproductive toxicity and transgenerational effects of microplastics: Evidence from experimental models and underlying epigenetic mechanisms
AI summary Read the abstract
Tiny plastic particles have been found in human reproductive fluids, and this review of animal research shows they can harm fertility in both sexes and may even affect the health of future children and grandchildren—not just people directly exposed. Scientists think microplastics may cause these lasting effects by altering "chemical switches" on DNA that get passed down through generations, changing how genes turn on and off without changing the DNA itself. While the animal evidence is concerning, more human studies are needed to confirm these effects happen the same way in people.
Micro/nanoplastic-induced alterations in cellular fate and full-cycle spermatogenesis: A mechanistic review and perspective on intergenerational risks
AI summary Read the abstract
This review pulls together animal and lab research suggesting that tiny plastic particles (microplastics and nanoplastics) can slip past the body's protective barriers in the testes and disrupt sperm production at multiple stages, damaging cell energy production and triggering harmful inflammation. Some studies even hint that this damage could potentially be passed down to future generations, though this research is still in early, preclinical stages and hasn't yet been confirmed in humans. Given how widespread plastic pollution is in our food, water, and air, this is an important area to watch as scientists work to understand what it might mean for human fertility.
The potential protective roles of Astragalus polysaccharides against toxicity of polystyrene nanoplastics on mice sperm exposed
AI summary Read the abstract
Tiny plastic particles (nanoplastics) harmed sperm quality and testosterone levels in mice, but a natural plant compound called Astragalus polysaccharides largely reversed this damage. While this study was done in mice, not humans, it suggests certain plant-based supplements might one day help protect fertility from everyday plastic exposure.
Synergistic Impact of Environmental Pollution and Occupational Stress on Sperm DNA Integrity Unveiling Hidden Drivers of Male Infertility
AI summary Read the abstract
This review pulls together existing research showing that everyday exposures, pesticides, heavy metals like lead, junk food, work stress, heat, and even microplastics, can team up to damage sperm DNA and lower fertility in men. Since male factors contribute to nearly half of all infertility cases, this matters because small, manageable changes like reducing processed food intake, managing stress, and limiting chemical exposure at work could meaningfully protect reproductive health. The authors note this is a summary of prior studies, not new experiments, and that some areas, like microplastics' exact role, still need more research to fully confirm the connections.
The Silent Legacy: Paternal and Maternal Exposure to Microplastics and Differential DNA Methylation in Human Oocytes and Zygotes
AI summary Read the abstract
This review examined evidence that both paternal and maternal microplastic exposures can alter DNA methylation patterns in human oocytes and zygotes, with potential intergenerational reproductive consequences. The authors found that phthalates and BPA carried by microplastics are likely epigenetic disruptors at the earliest stages of human development, though direct mechanistic evidence in humans remains limited.
