Is this witch infertility real and confirmed? I mean if all the witches are women and they are despised by society I would guess they wouldn't have a lot of chances in meeting men. Moreover, the witches of Cooperation Association got their knowledge from Cara, which is questionable.
Even though it's real, I wish Wendy would stop poisoning Nightingale with this infertility talk. Why she must further trample on Nightingale's broken heart? Best girl doesn't deserve this.
