Many clinics are managing hematocrit by recommending blood donation or phlebotomies to men with hematocrit over 53. They are also recommending treatment with low dose anastrozole for men with estradiol over 50 pg/mL. However, an alarming number of medical practices and research studies chose not to follow basic recommendations from the 4 current guideline groups that, in my opinion, may still need revision to add estradiol monitoring.
The table below shows a summary of monitoring required by the main 4 guidelines groups in the world.It is also imperative that future studies at least follow the minimum requirements of the current guidelines. The last few studies that concluded that testosterone may increase cardiovascular risks did not monitor or report hematocrit blood levels. Most guidelines recommend monitoring hematocrit at month 3, 6 and then annually. Are these studies liable for not following minimum guidelines and exposing their volunteers to increased risks?. I do not why I do not see discussions on this alarming fact. Institutional review boards (IRB's) need to educate themselves about this problem so that no more studies are allowed that do not properly monitor men on testosterone replacement.
