Gender Center

Gender constitutes the mental sex or sex that the person attests or affirms, which is in most cases consistent with sex representing physical sex at the gene level. However, some people’s sex does not match their gender. Such people are diagnosed with gender identity disorder (GID) as having a disorder of gender identity. Among people with disorders of sex development are people with GID who have a sense of discomfort with the distinction of sex on their family register. We have performed surgery for GID (Sex reassignment surgery) as the second facility in Japan since January 2001. Currently about 2,160 people are consulting a physician and receiving treatment for GID. Applying this surgery, we also provide treatment for disorders of sex development and external genitalia deformity.
For that reason, we established the Gender Center in September 2010 in Okayama University Hospital as a clinical division that provides diagnosis and treatment not only for GID, but also for wider gender-relates diseases on the whole through collaboration of the four clinical divisions of Neuropsychiatry, Obstetrics and Gynecology, Urology, and Plastic Surgery. To enhance the treatment further, the Gender Center was shifted from a collaborative section of clinical divisions to a central clinical department in September 2013. Patients with GID, disorders of sex development, congenital abnormality of genitalia, and genitalia deformity after removal of cancer or external injury have great distress that they usually harbor secretly. The Gender Center provides comprehensive treatment, including mental support, to those patients through a collaboration team of four divisions.
In 2012, the Center started laparoscopic sigmoid colon vagina construction with the cooperation of Gastroenterological Surgery.
In this way, we try to continue to provide the most advanced and minimally invasive treatment.

Management System

The Gender Center was organized by doctors of Neuropsychiatry, Obstetrics and Gynecology, Urology, and Plastic Surgery, nurses of Division of Nursing, and clinical psychologists of the Clinical Laboratory, while enlisting necessary cooperation from other external institutions.

Main Service Content

The core of the Gender Center’ service is the gender clinic. The clinic consists of four clinical divisions related to gender treatment and external committee members, following the “Guidelines for the Diagnosis and Treatment of GID (4th edit.)” advocated by the Japanese Society of Psychiatry and Neurology. In addition, apart from the clinic, we have a core member meeting consisting of doctors in charge and paramedical staff who actually provide treatment, in which practical matters for patients are discussed.
