Scientists have, for the first time, delivered a baby that was conceived by a frozen egg. This is a landmark for women who choose to wait to have children but fear their biological clock may not allow them to put off child bearing.
"This kind of levels the playing field between men and women cause we can actually freeze eggs and women can delay childbearing until later in life and have pregnancy rates as if they were younger," Dr. Jamie Grifo, New York University.
For years doctors have frozen sperm and embryos, but not eggs, fearing the egg was too fragile. But at New York University, doctors harvest the eggs with a needle guided by ultrasound. They have found the key is freezing and storing the eggs properly so they are not damaged.
More research will be needed before egg freezing can be routine.
