jan 1, 1980 - The first time "transsexualism" appears in the DSM-5.

Description:

There was no mention of "Transsexualism" and any other mentions of "gender identity" in the first two editions of the DSM-5. This was surprising since the term had increased attention since the late 60s and on. 1980 was the first time that the diagnosis “transsexualism” first appeared in the DSM-III.
