What this trial studies

This observational study aims to gather data on the physical and psychological effects of gender-affirming hormone therapy (GAHT) among transgender individuals in China. Participants seeking GAHT will be enrolled from a major transgender medical center and will undergo interviews and evaluations regarding their life experiences, gender identity, and health conditions. The study will follow participants for up to 12 months, assessing their mental and physical health before and during the hormone therapy. The findings aim to fill the gap in knowledge regarding transgender medical care in China.

Who should consider this trial

Good fit: Ideal candidates are transgender men and women aged 18 to 40 who wish to start GAHT and meet specific diagnostic criteria.

Not a fit: Patients with uncontrolled comorbid diseases, current psychiatric disorders, or a history of gender-affirming surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effects of GAHT, improving care for transgender individuals in China.

How similar studies have performed: While studies on GAHT exist globally, this specific approach in the Chinese context is novel and aims to address a significant gap in local data.
