NEW YORK (AP) — A 30-year-old infertile woman gave birth after surgeons removed her ovaries and reimplanted tissue they treated in a lab, researchers report.
The experimental technique was tried only in a small group of Japanese women with a specific kind of infertility problem, but scientists hope it can also help women in their early 40s who have trouble getting pregnant because of their age.
The new mother gave birth to a son in Tokyo last December, and she and the child continue to be healthy, said Dr. Kazuhiro Kawamura of the St. Marianna University School of Medicine in Kawasaki, Japan.
He and others describe the technique in a report published online Monday by the Proceedings of the National Academy of Sciences.
The mother was not identified. She had been diagnosed with primary ovarian insufficiency, an uncommon form of infertility sometimes called premature menopause.
Dr. Sherman Silber of the Infertility Center of St. Louis criticized the approach, saying he has had success by using drugs to treat the condition.
The new results, experts cautioned, must be viewed as preliminary.
