COLUMBUS (AP) — An Ohio proposal aimed at outlawing abortions would present some doctors with the choice between facing potential criminal prosecution or attempting a procedure considered medically impossible: the reimplantation of an ectopic pregnancy.

A doctor who terminates a pregnancy could face murder charges under the Republican-sponsored bill unless it is done to save a woman’s life. Even then, the proposal says doctors could be prosecuted unless they do whatever they can to save the “unborn child” as well, including trying to move an ectopic pregnancy into the woman’s uterus.

Such a pregnancy involves a fertilized egg implanted outside the uterus, which can lead to life-threatening complications for the woman. Reimplantation in such pregnancies isn’t physiologically possible, according to the American College of Obstetricians and Gynecologists.
