SAN FRANCISCO (KGO) -- Closing arguments are underway in San Francisco in a historic trial over frozen embryos.
Mimi Lee, a breast cancer survivor, wants custody of the embryos because she says they are her last chance to have children.
She signed an agreement with a man who was her husband at the time and UCSF.
The embryos were to be destroyed if the couple divorced and her ex-husband wants the contract honored.
The case is a key legal test of spousal rights over frozen embryos when couples split.
