Dr Mats Brannstrom, professor of obstetrics and gynaecology at the Sahlgrenska Academy, Gothenburg, who led the transplant team, said earlier that that all nine of the womb transplants his team performed between September 2012 and last April had been successful, with only minor complications.

Eight of the recipients suffered from a congenital disorder which affects one in 5,000 women and prevents the womb from developing.
The ninth had her womb removed after suffering cervical cancer, the report said.
Since the operation was so new, it was impossible to estimate the chance of success, Brannstrom said.
