Geographic Differences in Semen Quality among a Cohort of American Men Using Mail-in Sperm Testing Kits.

ABSTRACT:

Purpose

To evaluate the relationship between regional geography and sperm parameters in a cohort of American men using at-home mail-in semen collection kits with no previous self-reported history of male factor infertility.

Materials and methods

In this study, 5,822 men from six different regions of the United States (Northeast, Southeast, Midwest, West, Pacific, and Southwest) who self-requested semen analysis between 2019 and 2021 were enrolled.

Results

Across the entire cohort, the mean sperm concentration was 43.79±55.43 ×10⁶ sperm/mL; total sperm count 138.93±149.96 ×10⁶ sperm/mL; total motile sperm 54.73±81.90 ×10⁶/ejaculate; total motility 30.18%±22.87%; progressive motility 21.61%±17.32%; sperm with normal morphology 8.79%±8.87
