10 patients with aplasia vaginae et uteri (Mayer-Rokitansky-Küster-syndrome) were interviewed by 2 psychologically trained persons. Vaginoplasty had already been performed in 8 patients. For these patients, the time between their first consultation of a doctor and vaginoplasty had been rather difficult. During this time, they had the strong feeling of being different from other girls. This feeling was favoured by the lack of information about the kind of their anomaly and the operation. The preoperative well informed patients possibly tolerated the painful application of vaginal prosthesis better than others. All patients with aplasia vaginae et uteri had many questions concerning their exspected sexual relations. Their knowledge on sexual function was very poor. We think, that cooperation between gynecologist and psychologist or psychiatrist is necessary for good results in treatment of patients with the Mayer-Rokitansky-Küster-syndrome.
