Two women were able to give birth after womb transplants from their own mothers, it has been reported.
The babies - both boys - were born a month ago in Sweden and are doing well with their mothers at home, according to the Daily Mail.
The grandmothers underwent hysterectomies in order to allow their daughters the chance to experience motherhood.
Allan Pace, chairman of the British Fertility Society, told the newspaper:
The two new mothers had embryos frozen and only placed into the donor womb a year after the transplant was first performed.
The babies were delivered by Caesarian section.
