Foetuses 'cannot experience pain'
Pro-life groups say foetuses respond to stimuli from 20 weeks.

Foetuses 'cannot experience pain'
Pro-life groups say foetuses respond to stimuli from 20 weeks.
The US is considering legislation to make doctors tell women seeking an abortion it will cause the foetus pain.
It is also being suggested that, if the pregnancy is over 22 weeks, foetuses should be given pain-relieving drugs.
Dr Derbyshire, who is linked to pro-choice groups, said there were various stages of a foetus' gestation at which certain parts of the body's pain "alarm system" developed.
He concludes that pathways in the brain needed to process pain responses and hormonal stress responses are in place by 26 weeks.
