The so-called personhood measures would ban abortions by defining human life as beginning with conception.
Doctor Stephanie Dahl, a Fargo infertility specialist, said Monday the measures could also ban in vitro fertilization and force doctors to leave the state.
The Senate already passed the measures. The House is expected to consider them this week. One would make the proposal a state law. The other would add it to the state constitution.
Karla Rose Hanson, the organizer of the group opposing the personhood bills, says they're "even more extreme" than two other measures headed to the governor's desk. One of those bills bans abortion as early as six weeks into a pregnancy.
