Idaho Gov. Butch Otter (R) on Tuesday signed a bill into law mandating that women be told when getting an abortion that the drug-induced procedure can be stopped halfway.
The law, which will take effect July 1, has faced backlash from medical groups, The Associated Press reported.
In 2015, Arkansas passed a similar law that says women seeking an abortion must be told that "it may be possible to reverse the effects of the abortion if the pregnant woman changes her mind, but that time is of the essence."
The Idaho bill contains similar language, according to the AP.
Idaho state Sen. Lori Den Hartog (R) said she put forth the legislation because she wanted women to be presented with more information and to have choices.
Those who support the law say that after a woman takes the first of two medications for an abortion, a woman can be given the hormone progesterone to reverse the procedure.
Medical groups — including the American Congress of Obstetricians and Gynecologists — have come out against the law.
"Claims regarding abortion 'reversal' treatment are not based on science and do not meet clinical standards," the group posted on their website. "Politicians should never mandate treatments or require that physicians tell patients inaccurate information."
On Tuesday, a federal judge temporarily blocked a law in Mississippi that bans women from receiving abortions after 15 weeks of pregnancy. The law was the nation's most restrictive abortion ban.
