Harry Benjamin's Syndrome is an intersex condition developed in the early stages of pregnancy affecting the process of sexual differentiation between male and female. This happens when the brain develops as a certain sex but the rest of the body takes on the physical characteristics of the opposite sex. The difference between this and most other intersex conditions is that there is no apparent evidence until much later after the baby is born or even as late as adolescence.

Harry Benjamin's Syndrome was known in the past with many different names, being Transsexualism (ICD-10) the most common used in relation with it.

Over 60 years of medical research regarding Transsexualism (modern HBS) specify that there is NO evidence whatsoever that any psychological or environmental factors cause Transsexualism-HBS. All of the medical research done to date indicates conclusively that physiological (neurological, genetic) factors are the sole cause of Transsexualism-HBS

"Transsexualism (HBS) is now regarded by the world's leading experts in the field as another of the many biological variations that occur in human sexual formation -an intersex condition- where the sex indicated by the phenotype and genotype is opposite the morphological sex of the brain. People with the condition of transsexualism (HBS) are therefore born with both male and female characteristics and, like many others with atypical sexual development, seek rehabilitation of their phenotype and endocrinology to accord with their dominant sexual  identity; an identity which is determined by the structure of the brain. Transsexualism (HBS) is about being a particular sex, not doing it. It is also about recognising gender norms, not challenging them." -Karen Gurney & Eithne
Mills. 2005.
Murdoch University Electronic Journal of Law, Vol 12, No #1 & #2

There should be no escape for medical and legal authorities that these definitions ought to be corrected and updated when new information becomes available, particularly when our outdated definitions bring suffering to some of our fellow human beings."   - Professor Louis Gooren, MD. 2004, regarding current terminologies still in use for Harry Benjamin's Syndrome (old Transsexualism).
