Pioneering treatment with stem cells therapy reverses the symptoms of menopause.
Breakthrough raises the prospect of women having babies in their 50s with stem cells therapy.
Pioneering treatment that reverses the symptoms of early menopause has raised hopes that women affected could go on to have children naturally.
Stem cells from bone marrow were injected into the ovaries of 33 women suffering premature ovarian failure (POF) who began to have periods again after six months.
As well as treating early menopause, which can lead to women becoming infertile in their forties or earlier, it could also offer an alternative to hormone replacement therapy.
