In a survey we investigated whether gynecologists are sufficiently knowledgeable to perform genetic counseling. It provides information for the development and evaluation of a counseling manual for professionals in primary health care. The members of the sample, consisting of 529 gynecologists in northern Germany, were mailed a questionnaire concerning their knowledge of and attitudes towards genetic counseling and testing for hereditary breast and ovarian cancer (HBOC). The response rate was 32.5% (n = 172). The majority of the respondents (82%) have received requests from patients for genetic testing. Most would offer basic genetic counseling to their patients, 66% feel knowledgeable enough to do so. Physicians set high value on communicating clinical management options, but also consider psychosocial aspects to be important. The results suggest that HBOC genetics play a noticeable role in the practice of gynecology in Germany. There is consensus about the need for further educational training to deal with cancer genetics in physicians' daily practice.
