Not yet.<p>The earliest a child has been prematurely born, and survived, is 21 weeks after conception.<p>We have had embryos survive without a womb in a lab for 14 days (this is currently limited by federal law).<p>Thus, we really &#x27;only&#x27; have a 19 week gap to bridge. Not saying this is not a major challenge, but I believe this is worth of direct research.
