We also know hematocrit can be increased by testosterone preparations. It depends on the preparation, and we think that there is data that shows that the threshold of 52-54% should not be surpassed, and men should be controlled for the hematocrit especially in the first year of treatment every 3 months
Hematocrit & Thromboembolic Risk
* TTh increase Hematocrit -clinically relevant at >52-54%
* Recommended: Control Hematocrit every 3 months in the 1st year
* Elevated haematocrit is common with TTh, typically occurring within 3–12 mo. Levels up to 54% appear safe, but higher values may increase CV risk [15].
* Treatment adjustments are required for haematocrit >54% (requiring withdrawal and phlebotomy in high-risk cases)
