List the scientific discoveries that led to the change.
Twenty two years ago, on May 17, the World Health Assembly removed homosexuality from the list of mental disorders when it approved a new version of the World Health Organization’s International Classification of Diseases (ICD-10).
"Since homosexuality is not a disorder or a disease, it does not require a cure. There is no medical indication for changing sexual orientation," said PAHO Director Dr. Mirta Roses Periago. Practices known as "reparative therapy" or "conversion therapy" represent "a serious threat to the health and well-being — even the lives — of affected people."
The PAHO statement notes that there is a professional consensus that homosexuality is a natural variation of human sexuality and cannot be regarded as a pathological condition.
PAHO, which celebrates its 110th anniversary this year, is the oldest public health organization in the world. It works with its member countries to improve the health and the quality of life of the people of the Americas. It also serves as the Regional Office for the Americas of WHO.
