Increasing impact of oestrogen pollution through climate change
... Oestrogens are ‘female’ hormones that can enter the aquatic environment after excretion by humans and animals, causing ‘feminisation’ of male fish. This study carried out a risk assessment for oestrogen-like endocrine disruption in the UK in the 2050s, based on likely changes to the human population ...
