Study links outdoor air pollution to lower success rates in IVF cycles

A new study from Emory University indicates that outdoor air pollution can harm embryo development during in vitro fertilization (IVF) cycles. The research highlights the negative effects of pollution on both egg and sperm production. The study analyzed samples from 500 egg donors and 915 male partners undergoing IVF between 2008 and 2019. It found that exposure to organic carbon, a component of fine particulate matter, consistently reduced oocyte survival, fertilization rates, and embryo quality. Researchers emphasize that air pollution poses significant risks for those trying to conceive. They suggest that reducing exposure to pollutants should be a priority for individuals seeking to reproduce.
