Comorbidity of gender identity disorders.

TO THE EDITOR: Joost à Campo, M.D., et al. (1) reported that a high proportion of subjects with cross-gender identification suffers from comorbidity with other psychiatric disorders and concluded that their sex reassignment will eventually lead to regret. We are sensitive to the issue that patients may regret their sex reassignment (2, 3). However, we have reason to disagree with the authors since their research suffers from major methods shortcomings.
