Male personal heat exposures and fecundability: A preconception cohort study.

ABSTRACT:

Background

Several studies indicate adverse effects of selected heat exposures on semen quality, but few studies have directly evaluated fertility as an endpoint.

Objective

We evaluated prospectively the association between male heat exposures and fecundability, the per-cycle probability of conception.

Materials and methods

We analyzed data from 3041 couples residing in the United States or Canada who enrolled in a prospective preconception cohort study (2013-2021). At enrollment, males reported on several heat-related exposures, such as use of saunas, hot baths, seat heaters, and tight-fitting underwear.
