An Illinois appellate court is hearing a case about frozen embryos.
Karla Dunston was diagnosed with cancer in 2009.
She and her boyfriend, Jacob Szafranski, made embryos that were frozen.
They agreed not to use them unless both sides signed off.
The couple is no longer together.
Dunston believes they are her last chance at becoming a biological mother.
But, Szafranski doesn’t want to be forced to become a father.
The case could go to the Illinois Supreme Court.
