Sex matters in life and in law.
It shouldn’t take courage to say so.

Establish clarity on single sex services

2
Enable people to speak up
-
3
Make debate possible
What we do

- We support and mobilise people to speak up.
- We hold organisations accountable.

Organisations and governments should be clear about the sexes and where sex matters.
-
Human rights
Everybody’s human rights matter, including private life, freedom of beliefs and speech.
-
Democracy
A cohesive society depends on open debate and evidence-based policy making.
