Is there a secondary reason to have endo

I recently was diagnosed and have only seen one doctor but to finally come to this diagnosis ive had to see 7 gynocologists within the same practice and then do my own research and tell them to test me for it for them to consider it because they thought it was pelvic inflammatory disease and realized how very wrong they were when they performed the laparoscopy procedure im going to see a specialist in a month however just like my other disorder no one in my bloodline on either side has this is there another reason not because of someone's family that could cause them to have this disorder?
