NEW YORK — A 30-year-old infertile woman gave birth after surgeons removed her ovaries and re-implanted tissue they treated in a lab, researchers report.
The experimental technique was only tried 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, who was not identified, had been diagnosed with primary ovarian insufficiency, an uncommon form of infertility sometimes called premature menopause. It appears in about 1 percent of women of childbearing age. The cause of most cases is unknown, but the outcome is that the ovary has trouble producing eggs.
That leaves women with only a 5 percent to 10 percent chance of having a baby unless they get treated. The standard treatment is using donor eggs.
