Then she will need in vitro fertilization to become pregnant. Before the transplant, the patient had eggs removed surgically, fertilized with her husband’s sperm and frozen. The embryos will be transferred into her uterus.

The transplant will be temporary: The uterus will be removed after the recipient has had one or two babies, so she can stop taking anti-rejection drugs.

The Cleveland hospital’s ethics panel has given it permission to perform the procedure 10 times, as an experiment. Officials will then decide whether to continue, and whether to offer the operation as a standard procedure. The clinic is still screening women who may be candidates for the operation.

The leader of the surgical team is Dr. Andreas G. Tzakis, who has performed 4,000 to 5,000 transplants of kidneys, livers and other abdominal organs. To prepare for uterus transplants, he traveled to Sweden and worked with doctors at the University of Gothenburg, the only ones in the world to have performed the procedure successfully so far. Nine women have had the operation in Sweden, with the transplants taken from living donors. At least four recipients have had babies, who were born healthy though premature.
