Gender-Affirming Surgery
Dr. Jesús Lago performs feminizing and masculinizing surgery at Clínica 3 de Mayo in Madrid. He also operates on non-binary people, whose journey is neither feminine nor masculine. He welcomes patients from the UK, Ireland and beyond, and part of the follow-up can be done remotely.
Our Gender-Affirming Procedures at Clínica 3 de Mayo
Dr. Jesús Lago assesses every gender-affirming procedure against three criteria: aesthetic harmony, function and how well the result holds up over time.
Facial Feminization
The aim is to move from a square facial structure to a triangular one. The effect comes from combining changes to several volumes.
Neck and Voice Feminization
We work on the thyroid cartilage (the Adam's apple) to feminize your neck and voice. The technique depends on how long you want the result to last.
Genital Feminization
The aim is female genitals that work on three levels: appearance, function and anatomy. We choose the technique together, based on the depth you want, the level of risk you are comfortable with and how much dilation you are prepared to do.
Body Feminization
Creating a lasting feminine figure from a male anatomy, using implants or fat transfer.
Chest Masculinization
A flat, masculine chest with pectoral definition: we remove the gland, reshape the contour and send all removed tissue for analysis.
Face and Voice Masculinization
We masculinize the face and voice by adding volume and reshaping, for stronger angles and a more defined neck and voice.
Genital Masculinization
Male genitals are reconstructed in several stages. At each stage, we balance size, sensation and function.
Non-Binary Body Shapes
The aim is a flat genital area with no defined sex characteristics. The surgery is irreversible, so it requires a confirmed diagnosis of gender dysphoria.
