Rather than rely on females recognizing things about males, what about genes that capitalize on the difference between regular males and those with the disorder - sisters!

Females could more greatly than presently value aggression (this would only need a boost, the trait already exists), and a gene could make females intervene to break up their brothers' fights. Young males with the disorder would tear each other to shreds or be too timid to reproduce, and males without the disorder would have sisters preventing them from killing each other.
