According to an article from BBC News, Chinese doctors at Sun Yat-Sen University have created a fetus from two women and a man.

The process, outlawed in the US and the UK (and probably other places as well) involves taking the DNA from the "birth mother", transferring it into an egg from the donor mother and then later fertilizing it with the sperm from the father.

The result was three embryos, one of which was aborted early on, while the other two were born prematurely (4 months and 5 months) and subsequently died.

The process was actually pioneered in the US before it was outlawed as being too close to human cloning.
