The HTC Population Profile contains 51 transsexual individuals. For confidentiality purposes, the number of transsexual patients is too small to report by year or other characteristics. Transsexual patients have been included in the counts of male and female according to the sex assigned to them at birth since hemophilia and von Willebrand disease, the most common congenital bleeding disorders, affect the sexes differently. On August 10, 2020, the responses for this question changed such that “Male to Female” (i.e., transsexual) and “Female to Male” were removed and “Intersex” was added. The number of intersex patients is too small to report by year or other characteristics; therefore, these counts have been suppressed to protect patient confidentiality.

* Counts of five or fewer have been suppressed to protect patient confidentiality. Additional cells may be suppressed to prevent derivation of these counts by subtraction.
