I suspect this is a real contentious issue but why no female Primarchs? The answere that they came from Emps genetic composition doesn't work since males carry both male and female chromosones. An Empress would only be able to make girls but Emps could make both.

Given that the man was born back in 8000 BC my guess would be he simply didn't consider the role of war leader - or warrior - appropriate for females. But possibly there were peacetime roles he'd consider superwomen suited for.....
