[Ethical problems in prenatal diagnosis]

With regard to the aim of prenatal diagnosis two types can be distinguished, a therapy-referring and an existence-referring one. In the context of both types goods are endangered. From en ethical point of view both types are differently justified. In the scope of ultrasound-screening both types are mixed and special problems of counselling and informed consent emerge. In the context of genetic prenatal diagnosis a possible preimpact of a right to privacy is discussed. Finally several proposals are made concerning a collaboration of medical care and psychosocial counselling in the frame of prenatal diagnosis. Probably they can contribute to a protection of the endangered goods.
