Abortion: The Science and the Supreme Court

Fetal Pain

Wendy Zukerman explores the contentious issue of fetal pain, a topic that has surfaced in both scientific and legal discussions. Dr. Amita Murthy explains that for a fetus to feel pain, several developmental milestones must be reached, including the formation of pain receptors and the development of a complex cortex 1. She notes that while nerve fibers begin forming early, the ability to process pain through the cortex doesn't occur until much later in pregnancy 2.

You don't need the cortex for the reflexive action, but to understand that that is a bad thing and then that bad thing is pain you need the cortex for.

--- Dr. Amita Murthy

This understanding challenges assumptions made in legal opinions, suggesting that the perception of fetal pain is unlikely before 24 weeks 2.

   

Development Stages

The podcast also addresses common misconceptions about fetal development stages. Wendy Zukerman clarifies that while features like fingernails begin forming at ten weeks, they are not fully developed until much later 3. Dr. Amita Murthy describes the early stages of development, likening the initial cell formation to a "wriggling ball" that eventually forms a tiny, complex structure 4.

This little thing cooking, it's an embryo. It won't be a fetus for several weeks now.

--- Wendy Zukerman

This detailed explanation helps demystify the early stages of pregnancy, emphasizing that most abortions occur when the embryo is still in its very early stages 3.
