Endocrine disrupting chemicals impair the reproductive systems in wildlife. It has been hypothesized that endocrine disrupting chemicals may play a role in the decrease in the quantity of human semen during the last 50 years. However, linking the decline in sperm density to environmental factors may be premature. It is necessary to develop bioassays that would be able to evaluate and identify endocrine disrupting chemicals. We would like to introduce the system of testosterone synthesis as a possible biomarker for evaluating environmental chemicals.
