I haven't actually seen a specialist yet Emmy, I've just been to a GP who is giving me a referral to a gynaecologist. The GP told me that if my tubes were damaged, he was confident they could be repaired surgically. I've been researching on the net and haven't found a lot of info, like you said I've seen that they can sometimes block up again, but I've seen other information that if the person is young, the damage is not too severe, and there are no other problems causing infertility then surgery can be a good option.
I will be interested to see what the specialist tells you. This is probably a stupid question but I'm new to all of this, are there any other options besides IVF for blocked tubes?
