I don't know why this is news, because the effect has been known for some time. Maybe it's news because one species was quantitatively studied. Estrogenization has been a factor for PEOPLE in the Great Lakes basin for 3 decades, at least.
Birth control is not the only culprit. Chlorine has estrogen mimickers in its breakdown components. Triclosan is a hormone disruptor, and is in all of the anti-bacterial soap products and hand sanitizers.
People have been paying money for all of this stuff for years, and then flushing or washing it away without a thought. The advertising has been very successful. Scare tactics have been rather productive as well (SARS). Meanwhile, we are discovering that people are becoming sick because of a lack of good bacteria.
Birth control is necessary. Hygiene is necessary. Habitat preservation is also necessary.
