The Missouri Court of Appeals is being asked to decide whether a divorced St. Louis County couple's two frozen embryos are property or human beings with constitutional rights.

Jalesia McQueen, 44, is suing to be able to use the embryos, which have been stored for six years, to have more children. Her ex-husband, Justin Gadberry, 34, doesn't want to have any more children with McQueen and doesn't believe he should be required to reproduce.

The two signed an agreement in 2010 that would give McQueen the embryos if they divorced, but Gadberry sought to prevent that from happening when the pair did split. St. Louis County Family Court Commissioner Victoria McKee ruled in 2015 that the embryos were "marital property" and gave joint custody to the estranged couple, which required McQueen and Gadberry to agree on the embryos' future use.
