Does Testosterone Therapy Raise Blood Clot Risk

An American study that evaluated the effects of graded doses of testosterone on erythropoiesis found that the percentage of hematocrit started to increase within one month of the start of treatment and continued to increase after three months in a linear dose-dependent manner.9 The study also reported that increases in hematocrit were exaggerated in older men (60–75 years of age) versus young men (19–35 years of age). The study authors analyzed the levels of testosterone and concentration of red blood cells in the blood of 6,670 transmasculine individuals. If you’re at high altitude, your body naturally produces more red blood cells to compensate for lower oxygen levels in the air. All three can contribute to secondary polycythemia by depriving your body of oxygen and stimulating the production of extra red blood cells to oxygenate your tissues, says Shatzel.
This is a medical procedure similar to donating blood. Improving hydration may help bring levels closer to normal. Working with a lung specialist to improve breathing can help normalize hemoglobin. When breathing stops repeatedly during sleep, oxygen levels drop.
The typical log-linear, negative correlation between EPO and hemoglobin levels was shifted to the right by testosterone administration (21). Hematologic changes (sTR/log ferritin) were consistent with the expected increased iron utilization to meet the demands of increased erythropoiesis. Taken together, these changes in hematologic parameters support the hypothesis that buy testosterone cypionate increases iron utilization for erythropoiesis. Serum ferritin levels decreased in the testosterone group in parallel with hepcidin but remained unchanged in the placebo group (Figure 4C). The coefficient of variation for hepcidin, hematocrit, and hemoglobin was 0.47 (0.41, 0.53), 0.04 (0.04, 0.05), and 0.04 (0.04, 0.04) SDs, respectively.
Raising your testosterone levels can sometimes lead to lead to polycythemia. This is called polycythemia, and it’s a risk linked to all testosterone use. While taking testosterone-based HRT, your doctor will monitor your bloodwork for signs of polycythemia. Further studies are needed to test the hypothesis that purchase testosterone stimulates erythropoiesis by increasing EPO secretion and resetting its relationship to hemoglobin and by increasing iron utilization for erythropoiesis. It is not known whether erythrocytosis in response to testosterone administration in elderly men with mobility limitation poses risks or provides benefit. Recent studies have demonstrated that estradiol, divitube.com which is the product of aromatase-catalyzed testosterone metabolism, regulates hepcidin transcription and systemic levels of hepcidin in vitro and in vivo, respectively (35–37). Our studies in mice suggest that buy testosterone without prescription directly suppresses hepcidin transcription independently of its effects on EPO levels (26).
buy testosterone steroids administration significantly increased serum EPO level into the high normal range (13.5 ± 12 to 21.3 ± 17 mIU/mL) at 1 month; this 58% increase from baseline was statistically significant and remained significant at 3 months (Figure 3A). There was a small decrease in mean corpuscular volume and mean corpuscular hemoglobin concentration (Table 2) but no change in red cell distribution width or serum iron, iron-binding capacity, or percentage iron saturation (data not shown) in either group. Mean on-treatment hematocrit levels in men who experienced cardiovascular adverse events were similar to those without adverse events. Hemoglobin and hematocrit levels in testosterone-treated men peaked at month 3 in most participants and remained at these elevated levels for the remainder of the intervention period. Serum hepcidin and ferritin levels were within the reported reference ranges for men and similar between groups (15).
At 6 months, EPO and hepcidin levels returned toward baseline in spite of continued testosterone administration, but EPO levels remained nonsuppressed even though elevated hemoglobin and hematocrit higher than at baseline, suggesting a new set point. However, testosterone can also increase the concentration of red blood cells in the blood, causing a condition known as erythrocytosis, which thickens the blood and slows blood flow, potentially leading to life-threatening blood clots. Men with higher iron stores (ferritin levels) have more substrate for red blood cell production when testosterone suppresses hepcidin.
Drinking adequate water, especially before blood draws, gives you a more accurate picture. If your hematocrit creeps up, don’t panic. If your hematocrit was 48% and jumps to 52%, that’s worth discussing with your doctor even though you’re technically still in range. Once you’re stable, monitoring every six to twelve months is typical, though your individual situation might call for more frequent checks. Most physicians aim to keep hematocrit below 54%, though some are more conservative and prefer to see it under 52%. You might experience high blood pressure as your cardiovascular system strains against the thicker blood.
This is a usual “job” of testosterone. High hematocrit affects anywhere from 5 percent to 66 percent of cisgender men using TRT.

If you do have high hematocrit on TRT, you can take simple steps to reduce it. “Elevated hematocrit is a manageable but potentially serious side effect of TRT,” says urologist Joshua Calvert, M.D. Testosterone replacement therapy (TRT) can boost your energy, sex drive, and muscle mass–all things that can help you feel like your best self.
Many cases of blood clots in people on TRT are linked to other medical conditions that already raise clotting risk. Doctors treat rising hematocrit early to prevent blood from reaching the point where clot risk becomes meaningful. In reality, the risk depends on how high the levels go, how long they stay elevated, and other health factors a person may have. When TRT increases these levels, blood becomes thicker. Some methods cause rapid spikes in testosterone in the bloodstream, while others keep levels more steady.
