A 61-year-old woman has become the oldest surrogate mother so far recorded in Japan.

Reuters reports that the Japanese woman became pregnant with an embryo created from the egg of her daughter, who has no uterus, and sperm from the daughter’s husband. The maternity clinic would not confirm when the woman gave birth or give her name.

"The clinic hopes that Japan will hold forward-looking discussions on surrogate births and that it will take place in Japan without abuses," said the clinic, run by Yahiro Netsu, who has defied long-standing opposition to surrogate births from Japanese obstetricians.

Prior to the latest birth, the oldest surrogate mom known in Japan was a 60-year-old woman who became pregnant in the United States last year with an embryo created from donated egg and sperm.
