Exposure to microplastics leads to a defective ovarian function and change in cytoskeleton protein expression in rat
Researchers exposed female rats to polystyrene microplastics over multiple reproductive cycles and found, for the first time, that the particles accumulated in different parts of the ovarian tissue. The microplastics reduced ovarian weight, disrupted the normal development of egg follicles, altered the reproductive cycle, and lowered estrogen levels. The study suggests these effects are driven by oxidative stress and changes in key structural proteins within the ovary.

Researchers investigated how polystyrene microplastics worsen heart injury in mice, particularly when combined with the chemotherapy drug doxorubicin. The study found that microplastics aggravated cardiac damage through ferroptosis and mitochondrial dysfunction pathways, and that two protective compounds, Ferrostatin-1 and luteolin, showed potential in mitigating these harmful effects on heart tissue.
Pharmacotherapeutic potential of ginkgetin against polystyrene microplastics–instigated testicular toxicity in rats: A biochemical, spermatological, and histopathological assessment
In a rat study, polystyrene microplastics caused significant damage to the testes, including reduced sperm quality, oxidative stress, and tissue inflammation, but the natural plant compound ginkgetin was able to partially reverse this damage. Ginkgetin worked by boosting antioxidant defenses and reducing the inflammatory response triggered by the microplastics. This suggests that natural antioxidant compounds might help protect male reproductive health from the harmful effects of microplastic exposure.

Natural antioxidants like those in Moringa may help protect reproductive health from environmental pollutants.
Preventing ovarian aging: from redox-targeted strategies to extracellular vesicle-based therapies
This review paper summarizes research showing that ovarian aging (when a woman's ovaries stop working properly) can be sped up by things like smoking, unhealthy diets, chemicals in plastics, and tiny plastic particles we're exposed to every day. Scientists are studying treatments like antioxidants and special cell therapies that might help protect women's ovaries from this damage. This matters because healthier ovaries could help women maintain their fertility longer and reduce health problems related to hormone changes as they age.
Role of the Nrf2 Signaling Pathway in Ovarian Aging: Potential Mechanism and Protective Strategies
This review explores how the Nrf2 signaling pathway, a key defense system against oxidative stress, plays a role in ovarian aging, which leads to menopause, reduced fertility, and health risks like osteoporosis. While not focused on microplastics specifically, the Nrf2 pathway is one of the main systems that microplastics disrupt when they accumulate in reproductive tissues. Understanding this pathway helps explain how environmental pollutants like microplastics could accelerate ovarian aging and harm fertility.
