In late 2025, Wisconsin Senate Republicans passed SB553, a bill that defines embryos, fertilized eggs and fetuses as “unborn children” and “human beings” from the moment of fertilization. The bill passed with the support of every Republican senator and opposition from all Democrats. SB 553 also attempts to redefine the word “abortion,” asserting that a termination performed to prevent the death of a pregnant woman is not an abortion if it is not “designed or intended to kill the unborn child.”
Doctors also warn that SB 553 quietly functions as a personhood law by stating that once an egg is a human being from the moment of fertilization. By granting fertilized eggs status as human beings, the bill is giving those eggs legal rights which are equal to those of their pregnant mothers. While Gov. Tony Evers has said he will veto the bill if it reaches his desk, Wisconsin state Sen. Kelda Roys says its passage reveals Republican lawmakers’ intent.
Roys recently introduced the Pregnancy Loss Protection Act, the first bill of its kind in Wisconsin. Its goal is to prevent overzealous prosecutors or law enforcement officers from targeting people who experience miscarriage or stillbirth, while also pushing back against a broader Republican effort to confer legal personhood on embryos from the moment of fertilization.
