A 61-year-old Brazilian woman, who spent years trying to get pregnant, has given birth to twins.

Antonia Leticia Asti tried in-vitro fertilization in 2002. Failing to conceive she attempted adoption, but was told she was too old.

She became pregnant earlier this year after trying artificial insemination again using embryos from her first attempt which were frozen ten years ago.

"I'm now the happiest woman in the world," Antonia said.

The babies, a boy and a girl, are reported to be healthy but are still recovering in hospital.

A Spanish woman became the world's oldest mother when she gave birth to twins aged 66 in 2009
