No, not the same. But given your circumstances as long as you are “ordering towards procreation” it doesn’t mean that you have to be able to conceive.
Fostering is different.
It also comes with many risks. Very often children do not have a TPR (termination of parental rights) until after a foster family has had them for a while.
That said, it IS a vital conversation to have with your future spouse. While you are not required to do so due to infertility, it IS another calling altogether and it’s vital you are on the same page.
For the record, hubby and I did discuss the “what if’s” before marriage. We were both on the same page regarding biological chidlren and adoption.
