Thank you, is an ecoptic pregnancy the most common condition where an abortion is required to save the mother’s life? If so I wonder how many ecoptic pregnancies occur?
While I really don't know the numbers offhand, I'd guess that it's a rather small percentage of pregnancies. Applying a small percentage across the total number of pregnancies in this country every year, though, the absolute number is probably pretty high.
In all likelihood, there are almost certainly some number of other medical conditions that genuinely endanger the life of the mother. Sorry, I just don't know what they might be.
