Giving Standardized Estradiol Therapy In Transgender Women to Research Interactions with HIV Therapy: the GET IT RIgHT Study














Transgender women (TW) are the fastest-growing group of people with HIV (PWH). Historically, TW have had few opportunities to participate in research, and often experience barriers to engaging in care. More research is needed help providers when it comes to choosing HIV medications in TW on Feminizing Hormone Therapy (FHT).
