I guess KAren told them that Doi is the only male alive at the moment. And who knows what incitments the goverment gives to those girls. Then again I guess Karen made a thorough study of Doi and right now is playing her strategy accordingly. In contrast Sou just looked for women who might be interested in Reito. But no big plan to entice him to the idea of mating. She probably counted that his intelligence would make him accept this easily.
