A new study finds many fertility patients have difficulty deciding what to do with their unused frozen embryos.
There are about 500,000 frozen embryos in storage in the U.S. Many of which are left over from fertility treatments.
A Duke University researcher questioned more than one thousand people storing frozen embryos about their plans to dispose of them.
She found a majority of patients would not consider thawing and discarding them, donating them to other couples or freezing them indefinitely.
Over half said they would be open to donating their embryos for research, which is an option that is not always available.
