One step closer to a “three-parent baby”

Fertility treatment for older women uses eggs from younger ones


Using eggs from young donors to repair the damaged eggs of older women who hope to conceive, researchers are one step closer to creating a baby that, biologically speaking, has three parents. While they haven’t yet used these eggs to produce babies, they have been injected with sperm to produce an early embryo in the lab. The technique could be used to increase the chances of fertilization for older women, or to reduce the chance of genetic illness, but it’s also likely to provoke outrage among critics who say it could lead to genetically modified children. In vitro fertilization often fails in older women because of abnormalities on the outside of their eggs. But the team of researchers at St. Mother Hospital in Japan think they could implant the healthy nucleus, containing most of the information needed to produce a baby, into the cytoplasm of a young mother donor. They did this successfully in 31 eggs; of these, seven formed “early stage embryos” when injected with sperm in a test tube.

One step closer to a “three-parent baby”

  1. Just because we can do something doesn't mean we should.

  2. What Next???? Leave mother nature alone. if your body can't have babies, or produce normal eggs… adopt a child!!!!

    • You have obviously not been in a position where you have a husband who 'has sperm' but the sperm cannot exit his body normally. Thus a surgery is required; sperm removed from male and eggs taken from female (after a great deal of angst, $, hormone shots (and tears)…eggs and sperm united in petri dish to form and embryo – and then miraculously (with science and doctor's intervention) your adorable child is born. Words cannot capture the grateful feeling one has for the scientists and doctors who made this procedure possible! Please be open minded about these procedures as they are a blessed welcome for potential parents with fertility problems. Additionally, it is getting more and more difficult to adopt babies – For example, in the now more affluent China , women are postponing their childbearing and consequently face fertility issues themselves, and thus adopt the orphaned Chinese infants.
