The issue is that every OB/GYN has seen patients that regret the decision. And for most they will have seen instances where that regret ultimately led to suicide.
Do you really want to be the doctor that didn't press for more consideration for a patient that ultimately takes their own life?
I get the idea of giving women control but as a doctor it's also their right to refuse a procedure to not bear that burden. It's similar to the theory of justice that states it's better for 99 guilty men to go free than 1 innocent person to be punished.
It's easier to deal with a lot of angry patients vs one that commits suicide.
At least with the euthanasia there's not really going to be any rebounding patient regret to deal with!
