How can I unblock my fallopian tubes?

Why are your tubes 'blocked'?

Have you discussed the situation with your doctor?

There are various surgeries that can sometimes unblock fallopian tubes, but as Cat asked, how do you know that they are blocked? Did you have a screening done? If so, your doctor should have explained what options you might have. If you are only thinking that they may be blocked, perhaps due to not becoming pregnant, then you need to discuss it with you doctor.
