“…First, insurance access and coverage vary more in the US than other countries with centralized health insurance, and ART is often expensive even with insurance coverage (Katz et al, 2011 ; Wu et al, 2014 ). Second, the proportion of births due to ART is already higher in these other countries relative to the United States (Calhaz-Jorge et al, 2017 ; Raymer et al, 2020 ; Sunderam et al, 2019 ).
