在两性畸形中,生殖腺为睾丸而具有部份女性或完全女性的表现型者,即为男性假两性畸形。男性假两性畸形可根据个体表现型系部份或完全属女性而分两类。前者为不完全男性假两性畸形,又分为Ⅰ型及Ⅱ型。Ⅰ型系由于靶器官对雄激素反应减弱,Ⅱ型系由于5α还原酶缺乏所致,属常染色体隐性遗传病。后者为睾丸女性化症候群及XY单纯性腺发育不全。 In the genital deformity, the gonad is testes and has some female or fully female phenotype, that is, male false bisexual deformity. Male pseudohermaphroditism can be divided according to individual phenotypes, part or entirely of women and divided into two categories. The former is not completely male pseudohermaphroditism, is divided into type I and type II. Type Ⅰ system due to the target organ androgen response weakened, Ⅱ type due to lack of 5α reductase, is an autosomal recessive disease. The latter is testicular feminization syndrome and XY simple gonadal dysgenesis.
