[Sexual medicine in primary care--development in the years 1980-1990-2004]

Sexual disorders are common in community samples. Even so these problems are not often addressed by primary care physicians. In 1980, 1990, and 2004 three cohorts of primary care physicians in the German speaking part of Switzerland were asked to answer a questionnaire on the prevalence of sexual problems and disorders in their patients and their knowledge in sexual medicine. The prevalence of sexual disorders in primary care is underestimated by primary care physicians. Female doctors and female patients address sexual problems more often than male doctors and patients. Lack of sexual interest and erectile dysfunction are the most frequent sexual disorders in primary care. In 2004 the participating doctors assess their knowledge in sexual medicine at a higher level compared to 1980. The training of primary care physicians in primary care should further be improved.
