How close to death must a woman be to get an abortion in Tennessee?

The strictest abortion law in the US doesn't allow exceptions for medical emergencies - and efforts to change it face powerful opposition from the right

Months after the implementation of the most stringent abortion ban in the country, conservative lawmakers in Tennessee have publicly acknowledged that the state's ban poses grave risks to the lives of women.

Now a political debate over how to change the law is centered on questions that would have been considered unthinkable before last June's reversal of Roe v Wade: like how close to death a woman must be before a doctor may legally treat her if it means terminating her pregnancy, and whether women should be forced to carry embryos with fatal anomalies to term.
