An asessment of the issue of hematocrit increase after testosterone therapy and whether current guidelines are justified. The abstract is online and the full paper can be downloaded from the link. The conclusion is:
"Testosterone therapy (TTh) can effect an increased hematocrit via poorly understood mechanisms and may have harmful effects on blood flow that differ in patient subgroups. At present, there appears no scientific basis for using a hematocrit of 0.54 to modify TTh; other values may be more appropriate in particular patient groups."
