Summary

Two new studies of gender-bent fish shed light on the unfolding controversy over endocrine-disrupting chemicals. One study finds that fish from many U.S. streams are turning up with unusual levels of sex hormones. The other suggests that, in many cases, hormones found in women's urine—not synthetic chemicals—may be derailing the fishes' sexual developmental processes.
