AbstractIntroductionThere is a significant knowledge gap about sexual function in those assigned female at birth (AFAB) on medication for opioid use disorder (MOUD).ObjectiveThis study seeks to identify trends in sexual function among those AFAB receiving MOUD by utilizing the Female Sexual Function Index (FSFI) in an ambulatory obstetrics and gynecology setting.MethodsPatients at an ambulatory obstetrics and gynecology clinic filled out a survey assessing opioid use history, MOUD regimen, reproductive history, and the FSFI. Participants were eligible if they were older than 18 years, were assigned female at birth, and were currently receiving MOUD. The cutoff for identifying sexual dysfunction in participants was an FSFI score of 26.55.ResultsEight female participants receiving MOUD were approached for the study, and all eight completed the survey (100%) (Table 1). Four participants (50%) were sexually active in the past month. Of the sexually active participants, one was found to have sexual dysfunction and three were not (Table 2). The “desire” domain was the lowest average FSFI domain for sexually active participants (3.15 ± 0.78 out of 6 possible points). Of the four participants who were not sexually active in the past month, two stated lack of desire, one stated lack of desire and having given birth recently, and one stated both lack of desire and discomfort/pain during sexual activity as the reasons for absence of sexual activity in the past month. When asked if they had noticed a change in their sexual function after initiating MOUD, 75% (6/8) of participants reported noticing a severe, moderate, or mild decrease in sexual function overall and 87.5% (7/8) reported intense, moderate, or mild difficulty with arousal after initiating MOUD.ConclusionsLack of sexual desire appears to be a problem in this preliminary sample of women receiving MOUD. Half of the participants surveyed attributed the absence of recent sexual activity to difficulties with sexual desire, and in those who were sexually active, overall sexual function was mostly intact, but desire was still the lowest ranked domain. A larger sample size will allow for better understanding of the role that pregnancy, recent opioid use, and MOUD play in modulating desire as a crucial part of sexual function for those AFAB.DisclosureNo.
