Woman gives birth to grandchild

From an article of the same title on BBCNews.com:

A Japanese woman in her 50s gave birth to her own grandchild last year, using an egg from her daughter and sperm from her son-in-law, a doctor has revealed. It was the first time a woman has acted as a surrogate mother for her daughter in Japan, local media reported. The case is set to stir debate in Japan where surrogate births are opposed by the government and a key medical group. Japan's justice ministry also views the woman who gives birth as a child's mother - not the biological mother… She had agreed to in vitro fertilisation and to act as a surrogate mother because her daughter had had her uterus removed due to cancer and was therefore unable to bear children. Both the mother and child were reported to be in good health… Surrogate births involve removing an egg to be fertilised and then implanting it in another woman who carries the baby to birth.
