Study shows ambient PM2.5 pollution reduces success rates of assisted reproductive technology, posing risks to fertility‑clinic revenues and prompting potential air‑quality regulation
Executive summary: An international study presented at ESHRE 2026 found that higher ambient PM2.5 exposure is associated with reduced clinical pregnancy and live‑birth rates following assisted reproductive technology. The result indicates that air quality may directly influence the success and economic viability of fertility clinics, potentially driving demand for cleaner‑air facilities or regulatory action.
Who is involved: Researchers include Taipei American School student Jeffrey Zi Kang Huang, Taiwan IVF Group, Ton Yen General Hospital, and Stanford University, presented through an international collaboration.
Likely next: The findings are expected to be submitted for peer‑reviewed publication, after which stakeholders may advocate for air‑quality assessments near ART centers and conduct further epidemiological studies.
An international research team presented findings at the ESHRE 2026 conference linking higher ambient PM2.5 exposure to lower clinical pregnancy and live‑birth rates after IVF and similar ART procedures. The data, drawn from a multi‑site collaboration between Taiwan IVF Group, Ton Yen General Hospital, Stanford University and a student researcher, suggest that environmental factors could materially affect the efficacy of fertility treatments. While the study is preliminary and awaits peer‑reviewed publication, its implications extend to clinic operators, insurers and policymakers who may need to consider location‑based air‑quality standards.
