Kind: research · Impact: low

## In brief

- A study in mice examined maternal exposure to polystyrene nanoplastics.
- The reported effect is compromised ovarian reserve.
- The study links this to disrupted oocyte adhesion and granulosa cell homeostasis.

## Why it matters

The study suggests that nanoplastic exposure during pregnancy may affect the ovarian reserve of offspring, a question relevant to reproductive health research on environmental pollutants.
