Dr. Rosenfeld will review your operative notes from your tubal ligation surgery, if they are available. This will help him determine how much tube was cut, burned, tied, or if rings or clamps were placed. If he feels he can repair 6 cm or more, you will have a much better chance of becoming pregnant with tubal reversal compared to IVF. If your tubes appear to be less than 5 cm, or if your husband’s sperm count is low, Dr. Rosenfeld will refer you to the best IVF practitioner he knows.
