Distribution of male infertility specialists in relation to the male population and assisted reproductive technology centers in the United States.
OBJECTIVE
To describe the spatial distribution of assisted reproductive technology (ART) centers and male infertility specialists by location, driving distance from ART center, and potential male population in need of these resources.


METHODS
Cross-sectional study.


METHODS
Male population in the reproductive years (20-49 years old) based on U.S. Census Bureau data in 2000. Urology male infertility specialists as defined by 2005 specialty society membership directories. ART centers registered with the Society for Assisted Reproductive Technology in 2005.


METHODS
Male population and male infertility specialists within the service area served by in-state and neighboring-state ART centers, as defined by a 60-minute travel time.


RESULTS
One hundred ninety-seven male infertility specialists and 390 ART centers were identified. On a state level, the highest male population in the reproductive years was seen in California, Texas, and Florida. The highest male populations per male specialist were found in Oregon, Tennessee, and Oklahoma. The highest number of ART centers per male specialist was found in Tennessee. The highest proximities of male specialists within the 60-minute driving service area of different ART centers were found in the North East and Southern California. The Midwest to Northwest had the least.


CONCLUSIONS
A disparity of urology male infertility specialists exists in the United States, with large areas of the country being underserved and overserved based on the location of ART centers.
