Okla. Stat. tit. 63, § 63-1-745.5: Abortions prohibited when probable postfertilization

age of unborn child is 20 or more weeks – Exceptions – Procedure for

abortion.

A. No person shall perform or induce or attempt to perform or

induce an abortion upon a woman when it has been determined, by the

physician performing or inducing or attempting to perform or induce

the abortion or by another physician upon whose determination that

physician relies, that the probable postfertilization age of the

woman's unborn child is twenty (20) or more weeks, unless, in

reasonable medical judgment, she has a condition which so

complicates her medical condition as to necessitate the abortion of

her pregnancy to avert her death or to avert serious risk of

substantial and irreversible physical impairment of a major bodily

function, not including psychological or emotional conditions. No

such condition shall be deemed to exist if it is based on a claim or

diagnosis that the woman will engage in conduct which she intends to

result in her death or in substantial and irreversible physical

impairment of a major bodily function.

B. When an abortion upon a woman whose unborn child has been

determined to have a probable postfertilization age of twenty (20)

or more weeks is not prohibited by this section, the physician shall

terminate the pregnancy in the manner which, in reasonable medical

judgment, provides the best opportunity for the unborn child to

survive, unless, in reasonable medical judgment, termination of the

pregnancy in that manner would pose a greater risk either of the

death of the pregnant woman or of the substantial and irreversible

physical impairment of a major bodily function, not including

psychological or emotional conditions, of the woman than would other

available methods. No such greater risk shall be deemed to exist if

it is based on a claim or diagnosis that the woman will engage in

conduct which she intends to result in her death or in substantial

and irreversible physical impairment of a major bodily function.
