Fish found with male-female tissue


Fish with both male and female sex tissue have been discovered near Colorado wastewater treatment plants on the South Platte River and Boulder Creek.

Scientists are trying to determine if chemicals that disrupt hormones, such as estrogen, are responsible for the gender-bending phenomenon.

Colorado biologist John Woodling discovered the deformed white suckers about two years ago near two wastewater discharge pipes. Female fish also far outnumber the male fish near the plants.
