Proponents of week abortion bans often also cite Kanwaljeet Anand , a professor of pediatrics, anesthesiology and neurobiology at the University of Tennessee Health Science Center. He has stated that pain may indeed occur in a fetus, through other neurobiological mechanisms than in an adult, as early as 20 weeks post-fertilization or even before.
Kristi Noem, a Republican from South Dakota:. Noem, May This is the stage where we know the baby can feel pain, and could be viable outside the womb with proper care.

The study in question analyzed the outcomes regarding 4, babies born before 27 weeks gestational age. It is important to note that gestational age and post-fertilization age are different. Post-fertilization age is the time since conception. Generally, one can add two weeks to post-fertilization age to calculate an approximate gestational age. We are unsure to what exactly her 25 percent figure refers. In the study she referenced, a total of babies were born at 22 weeks gestational age, and 5.

The published scientific literature shows that unborn babies can experience pain at 20 weeks gestational age 20 weeks LMP, since Last Menstrual Period, the fetal age estimate used by most obstetricians or earlier. Medical practitioners have been using the latter method as standard medical practice for decades, and for the purpose of this paper ages refer to gestational age unless otherwise indicated.
A comprehensive review of the scientific literature [1] including neural development, psychology of pain sensation, and moral implications of fetal pain, concludes that unborn babies may experience pain as early as 12 weeks.
The review notes that neural connections from periphery to brain are functionally complete after 18 weeks. Significant because this unbiased review of the scientific evidence and agreement on existence of fetal pain , as early as 12 weeks and certainly after 18 weeks, comes from two highly credentialed medical professionals, one pro-choice. The basic anatomical organization of the human nervous system is established by 6 weeks. In fact, the human brain cortex does not fully mature until approximately 25 years of age, yet infants, children, and teenagers obviously can experience pain.
