A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Micro‐and nanoplastics (MNPs) are breakdown products of plastics, and humans are exposed to these particles through air, water, food, and soil. There is a growing concern that human exposure to MNPs negatively impacts health. In this review we will discuss the potential health impact of MNPs on ovarian function and the hypothalamic–pituitary ...

Organoids and organ‐on‐a‐chip models for investigating the pathophysiology of the human reproductive system

Interdisciplinary Medicine, EarlyView.
Organoids and organ‐on‐a‐chips are advancing reproductive system research. In the female reproductive system, applications include cancer organoid models, placental chips, and hormone simulation models. For the male reproductive system, research focuses on drug resistance mechanisms, co‐culture platforms, and infertility studies. These refined in vitro
