Ind. Code § 16-34-1-9

Sec. 9. (a) The general assembly finds the following:

(1) There is substantial medical evidence that a fetus at twenty (20) weeks of postfertilization age has the physical structures necessary to experience pain.

(2) There is substantial medical evidence that a fetus of at least twenty (20) weeks of postfertilization age seeks to evade certain stimuli in a manner similar to an infant's or adult's response to pain.

(3) Anesthesia is routinely administered to a fetus of at least twenty (20) weeks of postfertilization age when prenatal surgery is performed.

(4) A fetus has been observed to exhibit hormonal stress responses to painful stimuli earlier than at twenty (20) weeks of postfertilization age.

(b) Indiana asserts a compelling state interest in protecting the life of a fetus from the state at which substantial medical evidence indicates that the fetus is capable of feeling pain.
