title: [Increased risk of testicular dysgenesis?].
abstract: The latest figures from the Cancer Registry of Norway show that Norway has the highest incidence rate of testicular cancer in the world. They also show that the incidence rate continues to increase, as it has for the last decades in the western world. The reasons for this increase, which might also be true for urogenital abnormalities in men and reduced sperm quality, are uncertain. Data suggest, however, that these anomalies originate in foetal life, and that contributing factors are genetic, pregnancy-related and environmental. The potential importance of environmental factors must be taken seriously, and the authorities must take action to strengthen the research in this area.
