Doctors in Texas are now required to show sonograms to patients wanting an abortion.
The law passed last year, but a lower court judge had issued a temporary order against enforcing the measure, saying that several provisions were unconstitutional.
But on Tuesday, the 5th U.S. Circuit Court of Appeals in New Orleans overturned the ruling, allowing the Lone Star State to enforce the abortion law while opponents challenge it in court.
Under the new law, doctors will describe to their patients images seen in the sonogram, including the fetal heartbeat.
"The required disclosures of a sonogram, the fetal heartbeat, and their medical descriptions are the epitome of truthful, non-misleading information," Chief Judge Edith Jones wrote for the 5th Circuit.
Jonathan Saenz, a Liberty Institute attorney who provided the main legal testimony for the bill, said he was pleased with the court's decision.

"This is one of the most important victories in the past 10 years for informed consent for women seeking an abortion," Saenz declared.
"Women and unborn children in Texas are safer today because of this decision and no longer subject to the abuse of abortion doctors who deny women critical medical information," he said.
Texas Gov. Rick Perry, who signed the law earlier this year, also weighed in from the campaign trail.
"This important sonogram legislation ensures that every Texas woman seeking an abortion has all the facts about the life she is carrying," he said.
