What this research studies

This research investigates the effects of testosterone therapy on the voices of gender-diverse individuals assigned female at birth. It aims to understand how testosterone influences vocal fold and vocal tract anatomy, which may lead to changes in voice pitch and perception of gender. By examining these changes, the study seeks to provide evidence-based insights into voice masculinization, a crucial aspect of gender-affirming care. Participants will undergo assessments to evaluate the relationship between testosterone therapy and vocal characteristics.

Who could benefit from this research

Good fit: Ideal candidates for this research are gender-diverse individuals assigned female at birth who are undergoing or considering testosterone therapy.

Not a fit: Patients who are not assigned female at birth or those who do not wish to undergo testosterone therapy may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved voice masculinization treatments for gender-diverse individuals, enhancing their communication and personal safety.

How similar studies have performed: While there is speculation about the effects of testosterone on voice, this research aims to provide direct evidence, making it a novel approach in this area.
