Abstract
OBJECTIVE: To identify factors influencing sperm donor willingness to participate in direct-to-consumer genetic testing, comfort with sharing genetically identifiable data in commercial genetic testing databases, and likelihood to donate sperm again. DESIGN: Cross-sectional online anonymous survey. SETTING: Multicenter, 2 large American sperm banks from July 1, 2020 to July10, 2021. PATIENTS: Sperm donors from 1980 to 2020. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Associations between donor demographic characteristics, donation history, and attitudes toward direct-to-consumer genetic testing. RESULTS: A total of 396 donors completed the survey. Most donations (61.5%) occurred from 2010 to 2020, and 34.3% were nonidentified donations. Nonidentified donors were less comfortable with their genetic data being shared than open-identity donors (25.4% vs. 43.8%) and were less likely than open-identity donors to donate sperm again (43.3% vs. 72.1%). Donors who donated after the inception of direct-to-consumer genetic testing in 2007 were less likely to participate in commercial genetic testing than those who donated before 2007 (25.8% vs. 37.1%). Most donors (87.4%) have disclosed their donation(s) to current partners, but fewer have disclosed them to their families (56.6%) or children (30.5%). Of the donors who had been contacted by donor-conceived persons, 79.5% were identified via direct-to-consumer genetic testing. Overall, 61.1% of donors would donate again regardless of direct-to-consumer genetic testing. CONCLUSIONS: Direct-to-consumer genetic testing is playing a dynamic role in sperm donor identification, but donors seem willing to donate again. Implication counseling regarding future linkage and contact from donor-conceived persons needs to be standardized for potential donors before donation.
