How can states make it so that the involvement of women in government increases?

Various countries in Africa (and all over the world, for that matter) have quotas and reserved seats for women, but they fail (or ignore, maybe?) to meet them. Women’s involvement in politics has increased through the decades, but it is not to where it could be. What would it take for these numbers to grow. I believe quotas are a great way to start involvement, but a real change in the social fabric of society would have to take place before this increase happens. What are everyone’s thoughts? What else can be done?
