Finding F-1296

“Conversely, ozone exposure was associated with a 52% reduction in infertility risk.”

Long-term exposure to ambient air pollutants and female infertility risk a (2025). BMC public health. Page 1. CKB 3820

Structure

Factor: Ozone (O₃)
Outcome: Infertility
Population: women aged 15 to 60
Setting: city (ambient), TW
Study design: cohort of women aged 15 to 60 in Taiwan drawn from the National Health Insurance Research Database between July 2003 and December 2013: concentrations of sulfur dioxide, carbon monoxide, ozone, particulate matter, nitrogen oxides, total and non-methane hydrocarbons and methane estimated at the insurance registration address and related to incident infertility per standard deviation of ten-year exposure (class 3)
Effect: difference 52
Caveat: outdoor ozone estimated at the registration address, not an indoor measurement; ozone is the one pollutant of this study that points towards less infertility, which the study itself calls a converse result
