Okla. Stat. tit. 63, § 63-1-745.4: Abortion requirements – Determination of probable

postfertilization age of unborn child.

A. Except in the case of a medical emergency, no abortion shall

be performed or induced or be attempted to be performed or induced

unless the physician performing or inducing it has first made a

determination of the probable postfertilization age of the unborn

child or relied upon such a determination made by another physician.

In making such a determination, the physician shall make such

inquiries of the woman and perform or cause to be performed such

medical examinations and tests as a reasonably prudent physician,

knowledgeable about the case and the medical conditions involved,

would consider necessary to perform in making an accurate diagnosis

with respect to postfertilization age.

B. Knowing or reckless failure by any physician to conform to

any requirement of this section constitutes "unprofessional

conduct".
