Any way to reverse vasectomy naturally?

Hi All....not sure if I'm posting in the right forum or not, but my husband and I have been together for 4 years. We both have kids from previous marriages, but not together. He has had a vasectomy. We are now looking into some type of reversal, so we can have a baby together but in doing research, have found that this procedure is very expensive! Is there any natural way to do it, or do we have to rely on doctors and surgery for this?

TIA
