I'd like to point out that men also interrupt men, and women interrupt both men and women. Especially nerds. I'm a bit socially awkward, so I can never tell when it is a good time to start speaking. As a result I interrupt other people quite often. It's not intentional, I just don't know any better. I also don't care one iota what genitals you have.

You should not assume malice on the part of your co-workers. Just because someone interrupted you doesn't mean they don't value your input. In the case when it's obvious that they don't, don't hesitate to push back, but in most cases it's not going to be anything of the sort. It's just someone else being socially awkward while trying to wedge themselves into the conversation.
