Dr. Maria Kyne:

I do not think there are any barriers. For the most part, I think women do not put themselves forward, or they think they are not good enough to put themselves forward for these high jobs. They often have other commitments, including natural commitments at home and in other areas of their lives. They might, for example, have elderly parents. This means they do not tend to put themselves forward because of these other commitments. It is not their inability to do the job or a higher job.
