What is the connection between cervical polyps and infertility? I have been dealing with infertility for over a year now. My doctor was out of town this week so another doctor in the same office did a scheduled endometrial biopsy on me. (Ouch!). Before the Doctor got started, she said, "Wow! You have a very large cervical polyp (about 1/2-3/4") at the opening to your cervix. I am surprised Dr. So-in-so didn't see it." WTF!!!!! If this is the cause for all of our trouble, I am going to be totally upset. Actually, I already am that this wasn't caught before.
