Since the early 1990s reproductive technology has been used to help women get pregnant. However, future technology may make it so that they don't actually have to be pregnant. There is a strong possibility that one day in the very near future babies will be conceived and grow in artificial wombs that are hooked up to a placenta machine.
Scientists have been working on creating human sperm cells from embryonic tissue, as well as manufacturing eggs and even entire embryos. In 2001, researchers from Cornell University began growing sheets of endometrial tissue; when the sheets proved too thin to accommodate embryos, they were able to construct a freestanding uterus.
