Endocrine Disruptors in the Environment
Rainbow Darter Fish. R. Hays Cummins - Miami University.
Scientists have noticed a disturbing trend in the freshwater ecosystems in North America: a large number of male fish are found to contain female egg cells growing inside their testes. The
feminization of male fish is called intersex, and its exact cause is still baffling many scientists.
Many studies have shown that intersex can be induced when male fish are exposed to endocrine disruptors. However, it is easier to demonstrate the direct cause and effect in a laboratory
environment where the fish are only exposed to a single endocrine disruptor. In nature, there are many other variables such as low oxygen levels or warmer water temperatures that could also cause
feminization in fish.
