Critics say the so-called "heartbeat" bill would ban abortions before some women even know they're pregnant.
Iowa's governor signed legislation Friday prohibiting almost all abortions in the state after a fetal heartbeat is detected, making it the most restrictive abortion ban in the nation.
State senators who backed the measure said earlier this week that they were aiming to challenge the US Supreme Court's landmark Roe v. Wade decision that established that women have a constitutional right to an abortion.
Reuters reported on Wednesday that Iowa's senate passed the House of Representatives-approved bill by a 29-17 vote, leaving the legislation at the hands of Republican Governor Kim Reynolds.
"We have defended other abortion-related legislation, including the waiting-period and telemedicine laws".
What new restrictions have been approved?
The bill would require abortion practitioners to test for the unborn baby's heartbeat before performing an abortion. If one is detected, she will be barred from obtaining a termination.

The Republican-proposed legislation does include a handful of exemptions, such as protecting the life of the mother, pregnancies that occur as a result of rape or incest, or physician-certified fetal abnormalities that, in the doctor's "reasonable medical judgment", are incompatible with life.
Republican lawmakers are eager to advance pro-life causes ahead of the election race in case they lose their majorities. "But if death is determined when a heart stops beating, then doesn't a beating heart indicate life?"
At the rally, speakers included high schools students, representatives of the LGBTQ community, the Inter-Faith Alliance, the Emma Goldman Clinic in Iowa City.
"All women, regardless of age, income or race, should be able to obtain reproductive health services, including abortion, free from political and economic barriers", Ms Wessel-Kroeschell said.
Until Wednesday, the most restrictive abortion ban was in Mississippi. Those numbers haven't changed much in the past two decades, and the Supreme Court's abortion-rights ruling in Roe v Wade, 45 years on, continues to serve as a lightning rod.
There had been little doubt that Reynolds, who describes herself as "100 percent proline, would sign SF 359". MS passed a law earlier this year banning abortions after 15 weeks of pregnancy, but it's on hold after a court challenge.
"It's shameful that when Planned Parenthood heard lawmakers were introducing legislation to ban abortion, we were outraged - but we weren't surprised", said Suzanna de Baca, president and chief executive officer of Planned Parenthood of the Heartland. Rick Bertrand echoed a similar refrain, claiming the bill is "100 percent" meant to give conservatives "a run at Roe v. Wade".
