AUSTIN (January 25, 2012)--The Center for Reproductive Rights is seeking a rehearing of its argument that a law requiring a sonogram before an abortion is unconstitutional.

Two weeks ago the Fifth Circuit Court of Appeals lifted an injunction preventing Texas from requiring doctors to conduct a sonogram.

The law also requires doctors to show women the sonogram images, to play the fetal heartbeat aloud and to explain what the doctor sees, whether women want to hear it or not.

The three-judge panel ruled that the law is constitutional and said a lower court was wrong to stop Texas from enforcing it, but the center is asking for a rehearing by the entire appeals court to reconsider the earlier decision, which they say is wrong.

Texas is currently enforcing the law.
