7467 Supplement Use Among Transgender Patients: Case Reports and Literature Review

Abstract Disclosure: H. Cunningham: None. Q. Jones: None. C. Kelley: None. The barriers to initiating gender affirming medical treatment are innumerable and increasing in the wake of wide-sweeping anti-trans legislation, leading many transgender individuals to utilize more accessible means of transitioning. We provide examples of patient-initiated supplement use at a gender medicine clinic in the Southeast. We describe a 60-year-old transgender woman who was unable to establish care due to lack of affirming providers in her region and insurance approval delays. She began taking Pueraria mirifica, along with saw palmetto and fenugreek, for feminization. Subsequently, her breast size increased from an A to B cup, and she noticed fat redistribution to her hips. When finally seen one year later, labs demonstrated suppressed luteinizing and follicle stimulating hormones and increased sex hormone binding globulin, with an associated decrease in estradiol and testosterone levels. Cessation of supplements resulted in lab normalization. Our second case describes masculinizing effects, including voice deepening, experienced by a transgender man using a supplement that contained "orchic extract.” Supplements used for gender affirmation can also have more adverse effects, including polycythemia in the setting of trenbolone, an illicit steroidogenic performance enhancing supplement used for masculinization by some patients assigned female at birth. Patients without access to gender affirming hormones through a medical provider, or who do not feel comfortable accessing health care, may be more likely to use supplements purchased online without a prescription. Considering this, we must create more safe spaces for gender affirming care and ask all transgender patients about supplement use. Providers should consider supplement use as a possible explanation for unexpected lab results. The literature on supplement use for gender-affirming effects is sparse; this presentation provides a summary of and contributes to the current literature on this topic. Presentation: 6/2/2024
