Fertility Docs for ttc 40+??

Mcbethell
Me and my husband have been ttc for nearly 6 years. Spent lots of time and money for fertility treatments early in process but was told most docs stop treating patients after 42. So gave up going to docs and became discouraged with seemingly no where to go. 
Is this true? If yes, What are other fertility treatment options? If no, are there places in NC that can assist with 40+ ?
