In the last thirty years the way we have children has changed utterly. For the first time, the estimated eighty million infertile people worldwide have a chance to be parents. Humans are now effectively able to cheat evolution. But what are the wider consequences of this? In Everything Conceivable Liza Mundy, the first journalist to explore this subject in depth, meets gay families, surrogate mothers, egg donors and single mothers by choice. She looks at the workings of the fertility drugs industry, the phenomenon of eggs for sale, the increasing number of twins and the views of the Christian right and womenrs"s groups. And, as the meanings of life, birth, parents and families change, she asks: what are the real effects of the reproductive revolution?.
