日本のある性同一性障害クリニックにおける性同一性障害患者の臨床的特徴

この研究の目的は、日本にあるGIDクリニックにおけるGID患者の臨床的特徴を調査することだ。合計603名の連続した患者がGIDクリニックにおいて、臨床情報と、身体的神経学的検査を用い、評価された。DSM-IV の診断基準を用い、579名(96.0%) がGIDと診断された。4名は服装倒錯的フェティシズム、8名は同性愛、5名は統合失調症、3名はパーソナリティ障害、4名はその他の精神疾患のために除外診断された。GID患者の中で、349 名(60.3%)はFTMで、 230名 (39.7%)はMTFであった。 ほとんどすべてのFTMは思春期前に、身体的性別に違和感を持ち始め、女性に対して性的魅力を感じた。FTMで婚姻歴のあるものはとても少なく、子供のいるものもとても少ない。それゆえ、FTMは非常に同質な集団と思われる。一方で、MTFでは、発症年齢や、性的魅力の対象はさまざまなパターンであった。MTFでは28.3%に婚姻歴があり、18.7% に実子がいた。それゆえ、MTFはより異質な集団と思われる。

The aim of this study was to examine the clinical characteristics of patients with gender identity disorder (GID) at a GID clinic in Japan. A total of 603 consecutive patients were evaluated at the GID clinic using clinical information and results of physical and neurological examinations. Using DSM-IV criteria, 579 patients (96.0%) were diagnosed with GID. Four patients were excluded for transvestic fetishism, eight for homosexuality, five for schizophrenia, three for personality disorders, and four for other psychiatric disorders. Among the GID patients, 349 (60.3%) were the female-to-male (FTM) type, and 230 (39.7%) were the male-to-female (MTF) type. Almost all FTM-type GID patients started to feel discomfort with their sex before puberty and were sexually attracted to females. The proportion of FTM patients who had experienced marriage as a female was very low, and very few had children. Therefore, FTM-type GID patients seem to be highly homogeneous. On the other hand, various patterns of age at onset and sexual attraction existed among MTF patients. Among the MTF-type GID patients, 28.3% had married as males and 18.7% had sired children. Thus, MTF-type GID patients seem to be more heterogeneous.
