The Racial and Socioeconomic Characteristics of Men Using Mail-in Semen Testing Kits in the United States.

OBJECTIVE: To describe the racial and socioeconomic characteristics of men using mail-in semen testing kits for their fertility care in the United States over 3 years. METHODS: A cross-sectional analysis was conducted of men who used mail-in semen analyses from a single direct-to-consumer (DTC) fertility platform between 2020 and 2022. Age, race/ethnicity, place of residence, and education level of men using mail-in semen analysis kits was collected from user questionnaires. Zip code level socioeconomic status was estimated using the Area Deprivation Index (ADI). These characteristics were compared to the overall population of the United States. RESULTS: 4342 men used mail-in semen analyses from a single DTC fertility company between 2020 and 2022 and completed the questionnaire. The median age of this cohort was 36 (IQR: 32,40) years. The group consisted of predominantly white men (72%), with 7.9% Asian and only 5.1% Black, 3.2% Hispanic, 0.4% Indian American, 0.1% pacific islander, 5.8% mixed race, and 2.8% other groups. 45.8% of the group had completed college, 22% had a master's degree, and 9% had a doctoral degree. The mean ADI was 83.47 (SD 21.44) compared to the average ADI of 100 for the general US population (P < .005). CONCLUSION: DTC mail-in semen analyses have the potential to improve access to affordable fertility care. Racial and ethnic minorities and lower socioeconomic classes are underrepresented for men seeking DTC fertility testing as they are for men presenting for in-office fertility care. Additional studies are needed to determine the factors responsible for these discrepancies.
