Help us improve research on genital gender surgery! The GenderCOS study invites you to participate if you have professional experience or if you have had genital gender surgery.

The GenderCOS study aims to improve research on genital gender surgery by determining which outcomes are most important and relevant to measure. It will help improve surgeries and will make it easier to compare different surgical techniques and procedures. This is useful when considering which surgery best matches the wishes and expectations.

Your input coming from personal or professional experience can help shape future research, ensuring it is meaningful to those involved in the decision-making on surgery. Learn more and sign up for online participation starting in January 2024 at!
