About Association

The International Association of TransVoice Surgeons (IATVS) is a global network of laryngologists (voice surgeons) with extensive experience and dedication in the field of TransVoice surgery.
Our mission is to provide a platform for expert surgeons to exchange knowledge, advance surgical techniques, and raise awareness about voice surgery for transgender individuals.

Our founding members come from countries around the world and have collectively cared for thousands of transgender patients—supporting them in finding the voice that truly reflects their identity.

IATVS was established in response to the growing need for high-quality, individualized surgical care. We are committed to ensuring that every patient has access to the best available techniques, performed by experienced and compassionate professionals.

“Our goal is to raise the standards of voice care and continually improve surgical techniques in both feminizing and deepening the voice. Equally important to us are professional education and research in the fields of voice gender alignment and nuanced vocal adjustments.“
