I'm not sure about the cervical lesions, but I was on Avonex therapy, and all the literature says that you can still have children, but not to take the therapy. Pregnancy and childbirth might cause an attack, but you can control it once the baby is here. So far, they don't know if it is hereditary or not, so I don't understand why your neurologist is not wanting you to do this. How soon do you want another child, because maybe he wants you to do therapy now so that you can put yourself into "remission" and then try for another child. I don't know, but if you want another child, you shouldn't let the doctor tell you no. Maybe you should ask another doctor. I hope this helps you.
