Extreme ambient heat and outcomes of assisted reproduction in the continental United States, 1996 to 2018.

ABSTRACT:

Background

While extreme ambient heat has been associated with several adverse pregnancy and birth outcomes little is known regarding the link between extreme ambient temperatures and human fertility.

Objective

To evaluate the associations between extreme ambient heat and assisted reproductive technology (ART) outcomes.

Methods

Our analysis includes 1,087,379 patients in the continental United States who underwent 1,648,907 autologous oocyte, fresh embryo ART cycles reported to the National ART Surveillance System (1996-2018). Daily ambient temperature was derived by linking patient residential ZIP-code to a spatially refined gridded meteorology dataset. Three extreme heat metrics were created using different combinations of duration and intensity of hot days (mean da
