Transmasculine and Gender Nonbinary Individuals’ Assigned Female at Birth Experiences and Preferences With Emergency Contraception [ID 1366]

INTRODUCTION: Little is known about transmasculine and nonbinary individuals assigned female at birth and their experiences with emergency contraception (EC). Our goal is to determine use and reasons for EC choice in this population. METHODS: Transmasculine and nonbinary individuals assigned female at birth aged 18 and older participated in an online anonymous survey about their experiences with reproductive health care. The study was IRB approved by Emory University. RESULTS: Four hundred thirteen responded. The mean age was 34 (SD 8), and the majority identified as White (89%) and non-Hispanic (94%). Most were college educated (71%), and insured (91%). One hundred thirty-five (36%) needed EC, and 106 (79%) of those have used it: 62 (46%) before, 26 (19%) after, and 17 (13%) both before and after transitioning. Twenty-nine (67%) have taken EC while on testosterone. Five (17%) used ulipristal acetate (UA). Most (40%) chose UA because it was recommended by a clinician. No pregnancies (100%) occurred after UA. Twenty-three (79%) individuals used the levonorgestrel pill. The main reason was it did not require a prescription (41%). Eighty-two percent obtained levonorgestrel over the counter. Two (9%) became pregnant after taking it. Two (7%) opted for the copper IUD because it did not have hormones. Two (7%) chose the levonorgestrel IUD because it was long acting (50%) and recommended by a clinician (50%). Neither (100%) reported a pregnancy after either IUD. CONCLUSIONS/IMPLICATIONS: Transmasculine and nonbinary individuals assigned female at birth do use EC both before and after transitioning, and while on testosterone. More research is needed to better determine side effects and acceptance for those on testosterone in this population.
