Its not really fair to adjust for factors such as not taking time off to have kids. There are a number of biological reasons why it makes sense for women to be more involved in the early stages of rearing children than men (for example - only women can breastfeed).

For career focused women it is a very big problem that many career paths don't allow an easy way to take time off (or even just slow down a little bit) for children and then come back to reasonable opportunities.
