Thanks for that reply, Aristoddler.

In most jurisdictions, as I understand it, the time limit for abortion is based on the notion of foetal viability - the ability of the foetus to survive outside the uterus. I am interested in the idea of foetal sensitivity to the pain involved in the process as a possible criterion for a time limit. But to my disappointment I find that estimates for the onset of foetal pain-sensitivity vary considerably. It is on this last point that I am hoping for guidance.
