Scientists Use Stem Cells to Generate Human Eggs

Researchers at the Massachusetts General Hospital have extracted stem cells from human ovaries and have successfully made them grow egg cells.  Scientists that this would lead to a method for treating infertility, but would take much longer to achieve and also benefit biologists' understanding of how drugs and nutrition affect egg cells.

The Saitama Medical Center in Japan used the same method on donated human ovaries, donated by women who were undergoing sex reassignment, due to a gender identity disorder.  The team managed to extract stem cells that produced immature eggs that were then injected into mice.  The eggs generated follicles and a single set of chromosomes.  So far, researchers are still no where near being able to use this method on humans successfully, since they have not been able to overcome abnormalities in cells grown in laboratories, but believe that this type of research should still be approached with caution.

Question:
If this method of generating human ovaries was successfully, would this be any different from creating In-Vitro babies?  Or would this be a cure for women who are infertile and unable to use their own eggs?
