After groundbreaking studies in the Netherlands in the 1990s, many physicians are now considering HBS an intersexual condition with physiological origins.

At the same time, the so-called "transgendered" movement became ever larger and diffuse as more disparate and contradictory groups joined it. Moreover, people began to employ many new terms instead of the designation "transsexual".

Some of these new usages were Gender Dysphoria Syndrome, Benjamin Syndrome, and Transsexual Dysphoria. This has led to a serious lack of uniformity and scientific precision in the definition of HBS.

As the transgendered category became ever broader, people with medical transsexuality became merely a sub-set of this group, and this jumbled together individuals with genuine medical conditions with those who merely wished to exhibit "gender-variant" behaviour.

Another cause for anxiety was that the transgenderist movement tended to confuse the legitimate medical concerns of those with HBS with the political agenda of the homosexual lobby.

People with the classical form of medical transsexuality felt misplaced in the new transgenderist movement and alternatives to it began to arise. In the 1990s in Paris, a group began to call the condition "Benjamin’s Syndrome" (BS).

Unfortunately, they developed a model with a psychiatric definition, and this group ultimately rejoined the transgenderists. In Europe particularly, the initials "BS" have become attached to all sorts of homosexual and transgenderist organisations.

In time, activists attached this term to a plethora of possible causes for HBS, but they rarely, if ever, acknowledged that it was an intersexual condition with a neurological origin. The often attributed the cause of HBS to hormonal considerations, or to some yet-undiscovered "X-factor".

Aware of the confusion surrounding the condition, and tired of the resulting chaotic discussions in transsexual circles, in the Summer of 2005 Charlotte Goiar in Spain decided to attempt to popularise the term "Harry Benjamin’s Syndrome" (HBS), as it follows the naming conventions of intersex conditions.

Her concern was to keep the definition focused upon the intersexual and physiological nature of the condition, and try to keep the concerns of those with HBS distinct and discrete from those of the homosexual and transgenderist lobbies. This was a new and unprecedented development in the understanding of Harry Benjamin's Syndrome.

This term became more widespread in use in Europe, North and South America, and Australia. This definition has garnered bitter opposition from homosexual and transgenderist groups, and those allied to them. People such as Alejandra Victoria in Argentina picked up this idea only months after it started for this definition finally separated people with HBS from those whose agendas were inimical to a proper medical understanding of the condition.

HBS as a term is still a "work in progress", but it remains the most objective and unpejorative term available today.
