Air pollution negatively impacts IVF success rates

In a recent study presented at the European Society of Human Reproduction and Embryology's annual meeting in Amsterdam, researchers have found that exposure to air pollution can significantly reduce the chances of a successful live birth after in vitro fertilisation (IVF). The study, conducted in Perth, Australia, included approximately 1,800 patients and 3,700 frozen embryo transfers from 2013 to 2021. Women with the highest levels of pollutant exposure in the weeks leading up to egg collection had a 38% lower chance of giving birth to a live baby compared to those with lower exposure levels. Dr. Sebastian Leathersich, the lead author of the study and a fertility specialist in Perth, highlighted that the negative impact of pollution extends beyond early pregnancy stages and affects the quality of eggs as well. The findings underscore the urgent need for attention to environmental factors in reproductive health, as air pollution has been linked to various health risks, including stroke, heart disease, and lung cancer. Despite the study period having good air quality, the detrimental effects of pollution on fertility were still evident. The microscopic soot particles from air pollution have been shown to travel through the bloodstream and impact various organs in the body, including the ovaries and placenta. Dr. Leathersich emphasized the importance of minimizing pollutant exposure as a key public health priority. While individuals can take measures such as using air filters and keeping windows closed on high-pollution days, government and industry-level actions are crucial to effectively reduce emissions and protect reproductive health. The study's findings add to the growing body of evidence highlighting the harmful effects of air pollution on fertility and reproductive health. The researchers plan to further investigate the direct impact of pollutants on cells to better understand the mechanisms behind the negative effects. As policymakers work towards reducing traffic emissions, the study serves as a reminder of the need for continued efforts to mitigate the health risks associated with air pollution, especially for vulnerable populations.
