Women make up BPD heavily and there is also a vast amount of BPD's that have been sexually abused. In fact they have come up with a diagnosis that almost puts BPD's with SA in a separate category. It is called "Complex PTSD", which is not included in the DSM IV. It is also known as Disorder of Extreme Stress. BPD includes many that self injure/anamia and these behaviors are also very much weighted on the female side. But I agree that the physical and verbal abuse is also very invalidating and with the biosocial theory, BPD is the combination of extreme child invalidation and genetic predisposition.
