I'm a victim of the Celtic Cure aka hereditary hemochromatosis and also diagnosed secondary hypogonadism as a result. For me, the ferritin level at diagnosis was 2400 so pretty much a non brainer. However, people are diagnosed at much lower levels now as it has progressed from liver biopsy to a simply blood test / gene mapping to diagnose.
so like coastwatcher said, get tested to put your mind at ease.
