Tokyo - In a world first, a Japanese medical team has enabled a woman who went through premature menopause to give birth, using a unique method of freezing the patient's ovarian cells and cultivating them into pre-egg cells.
The breakthrough method was jointly developed by a team led by Kazuhiro Kawamura, associate professor at St. Marianna University School of Medicine in Kawasaki, and Stanford University.
The report was published in Proceedings of the National Academy of Science of the United States of America.
According to the team, the woman was 25 when she was diagnosed as having primary ovarian insufficiency. Although she underwent hormone treatment, ovulation did not occur. She had laparoscopic surgery to remove her ovaries when she was 29.
