Objective: Obsessive compulsive disorder (OCD) and autism share some common features, such as repetitive behaviors. Second finger to fourth finger ratio (2d: 4d) is thought to be associated with prenatal androgen exposure and differs between the sexes and 2d:4d ratio is reported to be more "masculine like features" in autism. The aim of this study is to compare OCD and autism that display common features in terms of 2d: 4d ratio and finger lengths.
