Residential Exposure to PM_2.5 Constituents and Fecundability in a Danish Preconception Cohort.

ABSTRACT:

Background

Epidemiologic studies have demonstrated that ambient concentrations of particulate matter < 2.5 μm (PM_2.5) are associated with reduced fecundability, the per cycle probability of conception. The specific constituents driving this association are unknown.

Objectives

We examined the association between ambient concentrations of PM_2.5 constituents and fecundability in a Danish preconception cohort study.

Methods

During 2007-2018, we enrolled female pregnancy planners in an Internet-based preconception cohort study. We included the 5905 participants who had been trying to conceive for < 3 cycles at study enrollment. Participants completed a baseline questionnaire and follow-up questionnaires every 8 weeks to update pregnancy status. We geo
