I think there's certainly a lack of support for men who are experiencing domestic violence, especially when the violence is coming from a female partner.
One issue is that it may be a less common form of domestic violence, but I also think quite a few people in the DV community are immersed in ideological positions about gender. I actually knew a woman who was the director of a DV shelter who said outright that it's ok for woman to hit a man, but it's not ok for a man to hit a woman. There just seem to be a lot of women (and men) who are pumped up with rhetoric about the moral infallibility of women, and the inherent culpability of men.
Even hotpeachpages.net, which has a great world-wide directory of domestic violence resources, describes itself as "Abuse information and support for every woman and girl on Earth". It's awesome that they have those resources, but you'd think they could at least mention men and boys, right?
That said, I think in principle there could be some DV resources listed that might help men too. If a resource has a name like "Family Violence Resource Center", then it sounds like it would be a better bet than something that says something about women right in the title.
