The world's first ever mother to daughter womb transplants have taken place in Sweden.
The procedures involved more than 10 surgeons at Sweden's University of Gothenburg. The patients identity has not been made public.
The surgeons involved have said that they will not consider the procedures to have been a success unless the women are able to become pregnant, "We are not going to call it a complete success until this results in children. That's the best proof", said Michael Olausson.

Prior to the operation, both women had their embryos frozen, so that they could be thawed and transferred into the women after a year of observation post surgery.
Both women were in their 30's and were said to be tired after the surgery. One of the women had to have her womb removed following treatment for cervical cancer a few years prior. The other was born without a womb.
Mats Brannstrom, Professor of obstetrics and gynaecology at the University said "The donating mothers are up and walking and will be discharged from the hospital within a few days".
Doctors in Turkey have said that they carried out a womb transplant last year, from a deceased woman to a young woman. However the doctors at the Swedish University hospital have said that the recipient in Turkey has not undergone fertility treatment to see if it was successful.
Womb transplants have been attempted in the past. A womb had to be removed from a woman in Saudi Arabia in 2000, following a bloody clot forming post surgery.
Only time will tell if these two procedures have been successful.
