PubMed
When searching the literature, be award that the language has changed, but there may be outdated terminology still lurking about. This doesn't mean that the science is not helpful, just be aware of the possible changes to be able to effective search and identify the literature.
For Example, PubMed now uses the Medline Subject Heading (MeSH) "Transgender Persons", defined as:
Persons having a sense of persistent identification with, and expression of, gender-coded behaviors not typically associated with one's anatomical sex at birth, with or without a desire to undergo SEX REASSIGNMENT PROCEDURES.
Year introduced: 2016 (2013)
However, the prior indexing was "Transsexualism", defined as:
Expression of a GENDER IDENTITY inconsistent with, or not culturally-associated with the gender assigned to an individual at birth, combined with the desire to permanently transition to the gender with which they identify.
Year introduced: 1968
You may want to include both terms in a search, especially if you want to identify papers prior to 2013.
Textbooks
Sometimes there can be a lag in updating language in textbooks and reports. Be sure to screen resources before allowing a patient to view outdating terminology that could make them uncomfortable.
