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.

Astragalus Polysaccharides Ameliorate the Toxic Effects of Polystyrene Nanoplastics on Boar Sperm
Scientists found that tiny plastic particles called nanoplastics can damage sperm cells by causing harmful chemical reactions, but a natural compound from the Astragalus plant can help protect against this damage. This study used pig sperm in lab dishes, so we don't know yet if the same protection would work in humans. The findings matter because microplastics are everywhere in our environment and food, and this research suggests natural antioxidants might help reduce their potential harm to reproductive health.
Oral exposure to polystyrene nanoplastics altered the hypothalamic–pituitary–testicular axis role in hormonal regulation, inducing reproductive toxicity in albino rats
This study found that oral exposure to polystyrene nanoplastics disrupted the hormone signaling pathway between the brain and testes in male rats, leading to reproductive damage.
