Oral exposure to polystyrene nanoplastics altered the hypothalamic–pituitary–testicular axis role in hormonal regulation, inducing reproductive toxicity in albino rats

Summary

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. The nanoplastics interfered with the hormones that regulate sperm production and testicular function. These findings add to growing evidence that nanoplastic exposure through food and water could be a contributing factor to declining male fertility.
