Asking for a friend who is 43 and childless. Is she being unreasonable to think that egg donation will greatly increase her chances of pregnancy? Her and partner have been TTC for 3 years and have unexplained infertility. She has been told that donor eggs increase chances dramatically but is that the case? I am lucky enough to have conceived with no probs so have no idea about these things. Is she being unreasonable or is it false hope?
