Sex hormones, insomnia, and sleep quality: Subjective sleep in the first year of hormone use in transgender persons.

Study Objectives: Transgender persons can use gender-affirming hormone therapy (GAHT) to align their physical appearance with their identified gender. Many transgender persons report poor sleep, but the effects of GAHT on sleep are unknown. This study examined the effects of a 12 months of GAHT use on self-reported sleep quality and insomnia severity.
