No person shall perform a partial-birth abortion except a physician who has determined that in his opinion the partial-birth abortion is necessary to save the life of a pregnant female or prevent great bodily harm to a pregnant female:
A. because her life is endangered or she is at risk of great bodily harm due to a physical disorder, illness or injury, including a condition caused by or arising from the pregnancy; and
B. no other medical procedure would suffice for the purpose of saving her life or preventing great bodily harm to her.
