Yes, it was done purposely, and there is a reason behind this which will not be covered in the race description but as part of the setting i am putting together and adventures i have planed.I read the description. I have to say I find them to be horrible people as a race for their treatment of the "genderless" variety. They make orcs seem pleasant and friendly. After all orcs treat everyone equally. Equally bad. But equally. Seems to me though that once artificial insemination became an available technology for them it would hit their culture like reliable birth control hit our world.
