Doctors in Denmark are hailing the case of a former cancer patient in Denmark who underwent an ovarian transplant and gave birth to a daughter after IVF is reported to give birth to another child who was conceived naturally.

''We performed IVF [in vitro fertilization] initially, and expected to do that for the second child also", says Claus Yding Andersen, MD, a professor in human reproductive physiology at the University Hospital of Copenhagen, who reports the case in the journal Human Reproduction.

Andersen posted his surprise over the procedure and the time long for which the transplants actually remained functional.

After eight months of cancer treatment and further a year of recovery, doctors again implanted 20 percent of an entire ovary.

Bergholdt's ovary began functional again after a few months, and she then had in-vitro fertilization to become pregnant. Nearly a year later, she gave birth to daughter Aviaja, now 3. Bergholdt's treatment was paid for by the Danish health system.

Also, it is revealed that ovarian transplants may also assist women whose fertility is impaired by treatments for other diseases such as autoimmune diseases.
