Are a woman's frozen eggs less viable than if those eggs are fertilized and preserved as embryos?

There have been several court cases over the frozen embryos of divorced couples where one partner wants custody of them and the other wants them destroyed.

I listened to the details of the latest one, where these five embryos are this woman’s only chance at having a child (due to cancer.)

However, the ex-husband wants them destroyed as per a multi-page agreement signed at the time of freezing them (and possibility not read thru all 10 pages.)

So, I couldn’t help but think that this women would have undisputed control over them if they were just her own unfertilized eggs.

Obviously no couple embarks upon the entire complex procedure of egg extraction, fertilizing them and freezing the embryos with the thought in the back of their minds about the possibility of divorce.

But it happens. The ex-husband can still have all the children he wants with someone else. But these five are this woman’s only chance.

So, would she not have been better off to just freeze the eggs? Or are they more viable as embryos?

Women, what would you have done under the same circumstances ?
