How many of them are educated as software engineers? (That's both men and women.) My experience is there are tons of people, male and female, in IT, particularly developing software, that couldn't engineer/architect their way out of paper bag. Good coders are rare as well. I think a lot of this has to do what is being taught in college these days and there are many working in IT that have little more education than a few corporate IT training classes.
All of my devs (5 current and the two new hires) have computer science degrees, a couple have a Masters.
My QA’s (5) all have degrees in something other than computer science or engineering.
