Why are there more men in rehab, and why same-gender socializing?

I seen that it’s more men than women in these places. I can’t buy addiction is a gender thing. Why is it there more dudes?

Also they are big on socializing with the same gender. Again, why’s that? I get it, with sponsorship, it should be the same gender. But why does it matter otherwise?
