First test-tube baby becomes a mother

Louise Brown, the world's first test-tube baby, has given birth to a child of her own.

The baby was said to be a boy. Louise, 28, an administrative assistant, and her husband Wesley Mullinder, 37, were said to be delighted at his safe arrival.

The birth of Louise on July 25, 1978 made headlines around the world. It was the culmination of 12 years' research by a British team headed by Dr Robert Edwards and Dr Patrick Steptoe.

Unlike her parents, Louise was able to conceive naturally and did not need IVF treatment.
