There’s an article just gone up in The Guardian about the presence of anti-androgens and estrogen-like substances in common household goods. This being science journalism in a popular newspaper I’m a little skeptical, and I’ll try to find the EU report on which it is based. However, this paragraph did catch my eye:

Research has suggested that male foetuses around 8-12 weeks after conception can be effectively demasculinised by exposure to such chemicals.

Just in case anyone needs reminding, our understanding about how the physical and psychological aspects of gender develop is very poor, and if that process is being disrupted it becomes even more important that we move beyond the simplistic, and in many cases cruel, straitjacket of a binary gender system.
