I can't remember, I know they both ate the cookies but it was never certain that one of them went infertile. (I know that he is cause of spoilers and such) But for them it isn't clear, some people just can't get pregnant from another person even if the other person get other people pregnant and the same with woman, some pairs just won't work together cause of dna or such things, so if I were them after finding out the woman was pregnant from another man I wouldn't jump to conclusions that I was infertile cause I wasn't able to impregnate the woman
