The males reproduce. They aren't a recessive gene. The females do not reproduce and enough bigger guys than casual hobbiests have tried enough times that THEY care enough about the life of a single female to not ever breed females again.
With all the cases of females dying, any one else trying would be blatantly giving their females a death sentence, which I personally find extremely wreckless.
Even if ONE person successfully got a female to reproduce, it would only serve to be a death sentence to more females as others tried to be that 1% chance.
