Question

Is there a chance to be pregnant although you're not fertil?

Answer 1

No.  If you're proven to be infertile, then there is no chance of pregnancy.

However, there are cases in which women are told that they ARE infertile, and somehow, amazingly, they find themselves pregnant.  In that sort of case, the diagnosis of infertility was a mistake.
