I have been diagnosed with erythrocytosis, but my hemoglobin levels fluctuations correspond with testosterone levels. The higher my testosterone, the higher my hemo count. I am on synthetic androgen. My doctor referred me to an oncologist but I think I need to look at a different form of Androgen because there is no doubt that the topical Androgen is the root cause of the problem. I'm putting the oncology option on hold until I see a urologist.
