A woman, Stinne Holm Bergholdt of Denmark, has given birth to two babies after her fertility was restored using transplants of ovarian tissue, the first time the highly complex treatment has produced two pregnancies.

"This is the first time in the world that a woman has had two children from separate pregnancies as a result of transplanting frozen and thawed ovarian tissue", said Andersen, the women's doctor.

Claus Yding Andersen, the Danish doctor who carried her whole treatment, posted that the case depicted how this method of storing ovarian tissue was a valid treatment of fertility preservation and should encourage the technique to be used more in girls and young women facing treatment that may damage their ovaries.

The woman is reported to have given birth to a girl in February 2007 after receiving fertility treatment. However, then, in 2008, she found she had conceived a second child naturally and gave birth to another girl in September that year.

Her cancer treatment was reported to be a success, as expected, the drugs caused a menopause. In 2005, six strips of ovarian tissue were transplanted on to what remained of her right ovary. Her ovary began to function again and, after mild ovarian stimulation, she became pregnant and had her first daughter.
