Scientists took the outer tissue containing follicles that produced eggs from the ovary of this person to transplant into the ceased ovaries of the other in the same twin sisters.

The risk of transplant rejection is very low because twins have identical genes.

Last year, Stephanie Yarber suffered from menopause at the age of 14, had a baby after being implanted by doctors from the tissue of her twin sister. Tu has so far had five women with ovarian transplants, of which three were pregnant.

According to the research results published in the journal Human Reproduction, twins have the rate of early menopause three to five times higher than normal women.

The study was carried out by Dr. Sherman Silber of St Luke's Hospital in France and Dr. Roger Gosden of Cornell University in the US, based on data on 832 twins in Australia and the UK.

Dr. Gosden said so far has not identified the exact cause of this phenomenon. But early twins who have menopause may be inherited from an early menopausal mother.

Dr. Allan Pacey, secretary of the British Reproductive Society, currently teaching at the University of Sheffield, says that this implant technique can help store ovarian tissue for a long time for women to have to remove part of the chamber eggs for cancer treatment.
