That is the theory, yes; but that is being challenged regularly. There are no guarantees. There are also other issues besides not being contacted. What if the woman was raped and doesn't want her rapist to have offspring by her, whether she ever had to meet them or not? What if she doesn't want to add to the human population of the planet? Personally, I think it's creepy to force her to yield up reproductive matter out of her own body to grow another person against her will.
