Publications under ‘Environmental Exposures’ examine the associations of environmental exposures with fertility and reproductive outcomes.

Exposure to environmental chemicals is ubiquitous among reproductive-aged Danish women. Better understanding of the health effects of chemical exposures during pregnancy is needed.

The probability of conceiving may vary by season: couples were most likely to conceive in the late fall and least likely to conceive in the late spring. This association was strongest at southern latitudes.

Women who live close to major roads and who have a higher density of major roads around their home had lower fecundability than women who lived far from major roads.

Among Danish pregnancy planners, we estimated concentrations of several air pollutants at each participant’s residential address. We found that participants with higher levels of particulate matter around their homes took longer to conceive relative to participants with low levels. Other air pollutants, including nitrogen dioxide, sulfur dioxide, carbon monoxide, and ozone were not strongly related to time-to-pregnancy.
