Can you tell me what you have personally experienced if doctor had infertility?

Same as You! I have had many physicians who needed infertility care. My wife and i had trouble but we fortunately had a pregnancy without treatment. My physician patients have the same tests and treatments and any other patient. I may use bigger words with the physicians but otherwise, i assume that they are not experts in infertility. They have the same concerns and frustrations as everyone.
Just like everyone. They seek medical care like everybody else. Their response to recommendation though is sometimes impeded by their own medical knowledge. The majority though just follow doctor's advice.
