If human males eat feminised fish, will they become more feminine too?” Silverwing Benoir, Second Life

We put this question to Professor Karen Kidd:

There’s a lot of concern about oestrogens in the environment and what they're doing to our health, but in this case, we’ve looked for estrogens in fish muscle and have found no evidence that they concentrate in the muscle or any parts of the fish that we eat.  So, in this case, it’s not a risk to human health.
