What this trial studies

This observational study aims to explore the effects of testosterone treatment on transgender men and non-binary persons, focusing on various health aspects such as cardiovascular status, muscle strength, aggression, and quality of life. Conducted at the Body Identity Clinic in Denmark, participants will be monitored before and during testosterone therapy over a period of up to ten years. The study seeks to understand the potential development of non-calcified coronary plaque associated with testosterone treatment, contributing to the ongoing discussion about its short- and long-term effects.

Who should consider this trial

Good fit: Ideal candidates for this study are transgender men and non-binary persons seeking testosterone treatment.

Not a fit: Patients who are not transgender men or non-binary individuals may not receive any benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the health impacts of testosterone treatment, guiding safer and more effective care for transgender individuals.

How similar studies have performed: While there is ongoing research in this area, the specific focus on cardiovascular effects and non-calcified coronary plaque in this population is relatively novel.
