It may happen that they are not "compatible" not because it is another man. but by blood factors. An Rh0 negative woman cannot have an Rh positive child. The organism itself attacks the baby like a stranger and produces spontaneous abortions. That is why in those cases the woman is medicated to be able to have the baby with another type of Rh factor so that it will no longer attack it and the baby grows normally.
It is one of the many causes

and there is a difference between being infertile and sterile
its not its about the fertilisation baby is called embryo what u telling is after the phase of fertilisation when embryo is formed i am taking about before formation of embryo all sperms fuse all ova of humans theres no thing called compatabilty the above person said about pregnancy pregancy is when sperm ova fuses together at taht time theres no correlation of blood type but after development of fetus complication happen because of negative blood group baby means fetus remember being pregnant doesnt means fetus it means her ova fused with the sperm and is in early stages sauch as zygote then cleavge process following morula blastocyst etc( u acn trust this information i am doing mbbs)
yeah theres a difference between setrile and infertile , super male or super female who have chromosomal defects as such having an extra pair of chromosomes they are sterile and thosse humans who have normal chromosamal patters but still are unable to reproduce they are infertile enuchs are other case of being sterile
u get pregnant even if theres a blood compatability thing but later the developed baby will die which is called abortion theres a difference between abortion and getting pregnant things happens after single cell fused cell called zygote goes into next stages and forms developing fetus ,zygote forms no matter what diseases or combatablity things are there it doesnt matters , if zygote forms you are detected being pregnant thats what being pregnant means it doesnt beans that your uterus has a fetus ,being pregnant defines the earlist srage of fusion of gamestes which is having a formed zygote
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
