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 ...

Fertility and Early Embryonic Development Toxicity of hzVSF‐v13 in Sprague–Dawley Rats

Journal of Applied Toxicology, EarlyView.
ABSTRACT Humanized virus suppressing factor–variant 13 (hzVSF‐v13), a monoclonal IgG4 antibody, is a potential therapeutic candidate for COVID‐19. Although fertility and embryonic developmental toxicity studies are crucial for the safety evaluation of new drugs, the toxicological profile of hzVSF‐v13 remains unexplored.
