Answered on: 24 April 2019

The Environment Agency (EA) has previously carried out an extensive research programme into the feminising effects of hormones in treated sewage on wild roach populations (Rutilus rutilus) (https://www.gov.uk/government/publications/the-identification-of-oestrogenic-effects-in-wild-fish).

In the autumn of 2019 the EA will be publishing the results of research undertaken recently to investigate the current levels of feminisation in similar fish populations, as a comparison to the previous study.
