Grodor byter kön Publicerat i SvD nätbilaga: 22 februari 2007, 18:38 Med östrogen i vattnet blev det inga hangrodor. Ynglen fick äggstockar i stället för testiklar. En studie vid Uppsala universitet visar vilka drastiska effekter utsläppen från reningsverken kan få. Miljögifter i vissa bekämpningsmedel och plaster har samma verkan. Problemet
Niels Erik Skakkebæk, Department of Growth and Reproduction, Rigshospitalet: Men in industrial countries make fewer sperm cells than before and suffer from testicular cancer more frequently. Why? We came up with the hypothesis that chemicals, acting as hormone disrupters can be found everywhere in the environment and are suspected to harm the sexual development of a male fetus. Sometimes these chemicals act like female hormones. In other cases they inhibit the function of the male hormones. Problemet
