Do you think air pollution should be considered when planning fertility treatment?
A study led by Grade 11 student Jeffrey Zi Kang Huang, presented at the 2026 ASRM Scientific Congress in Baltimore, found a trend toward lower IVF pregnancy and delivery rates in European countries with higher PM2.5 air pollution exposure. The findings were not statistically conclusive, and the country-level analysis cannot establish direct causation.
Why it matters
Fertility treatment is a significant medical and financial commitment for many families, and environmental factors that affect success rates could inform future clinical guidance. The research is an early signal that air quality may be one variable in reproductive outcomes, though further study is needed.
The analysis drew on reproductive treatment data from 27 European countries via ESHRE and World Bank air pollution estimates, showing a 2.39-point drop in delivery rates and a 1.91-point drop in clinical pregnancy rates per 5 µg/m³ PM2.5 increase. The results were not statistically conclusive, and the country-level design cannot isolate individual exposure.
The players
Jeffrey Zi Kang Huang
A Grade 11 student at Taipei American School who served as first author and presenter of the multinational IVF and air pollution study.
Dr Barry Behr
Professor Emeritus of Obstetrics and Gynecology at Stanford University School of Medicine, who mentored the research and has published roughly 300 scientific papers and abstracts.
The details
Jeffrey Zi Kang Huang, a Grade 11 student at Taipei American School, was first author on the study titled 'Ambient Air Pollution and IVF Outcomes in Europe: A Multinational Registry Analysis of PM2.5 Exposure.' He conducted the work under the mentorship of Dr Barry Behr, Professor Emeritus of Obstetrics and Gynecology at Stanford University School of Medicine, and presented it at the ASRM Scientific Congress & Expo in Baltimore.
Timeline
August 2025: Huang joined Taiwan IVF Group and Ton-Yen General Hospital as a research intern.
October 12, 2026: Huang's article on air pollution and fertility treatment outcomes was published in BioNews.
2026: The study was presented at the ASRM Scientific Congress & Expo in Baltimore.
Health Landscape
The study builds on the European Society of Human Reproduction and Embryology's country-level IVF registry, adding PM2.5 exposure data to test whether environmental factors track with treatment outcomes. It represents an emerging line of research connecting air quality to reproductive health alongside established clinical determinants of IVF success.
Individuals undergoing IVF may eventually see air quality considered as a factor in treatment planning, though the current findings do not support changing care. The results are preliminary and not statistically conclusive, so they do not yet translate into individual recommendations.
The takeaway
Air quality may be one of many environmental variables affecting fertility treatment, but the study is preliminary and cannot prove cause. Patients should continue to rely on their fertility specialists for individualized guidance.
