No they don't have women there.

they summon women, how are they unable to reproduce. if they summon they would be able to reproduce, have more girls, those girls have kids yada yada no longer needing to summon. that's what I'm askin

I see, that's the point, but it hasn't shown anything about that.

I bet they are all impotent and few aren't and most gather mana drain the life of the girls and throw them after.
