Urologist suggest correlation between hematocrit and T....but none exist in my medical history.

[CuirPork]

I have hematocrit levels around 50% since the day I started at this clinic more than 10 years ago. I get my blood tested every 4-6 months and there has never been a significant change in my Hematocrit. However, my testosterone has been as high as 1400 and as low as 33. With such a significant range in testosterone levels, surely if there was a direct correlation between hematocrit and Testosterone, I should see a significant range in hematocrit.

According to a report on PubMed,

Hemoglobin and hematocrit increased significantly in a linear, dose-dependent fashion in both young and older men in response to graded doses of testosterone - <https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2266950/>

They go on to state that most experience an increase during the first 12 weeks and usually max out and stabilize around 20 weeks. I showed less than 1% change over the time period indicated.

You would think that when I switched to Defy Medical and my Testosterone went through the roof, that I would see some impact on my hematocrit, but nothing.

Does this urologist have a valid point or are there exceptions to this rule? Should I be concerned? Can I get my hematocrit tested somewhere else after I spend some time getting hydrated (I hate to drink liquid and dehydration affects hematocrit)? Do you need a prescription to get phlebotomized? Any suggestions? Thanks in advance.

If you were at 50% before TRT you should have been tested for sleep apnea. The normal red blood cell life cycle is 120 days. If your T dose is too high, you will build up hematocrit over time. There are some vitamins that have effect on the red blood cell life cycle. I think Vitamin E is one that extends the red cell life cycle.

Things I think that made my hematocrit high before was sleep apnea, Juicefestiv supplement and a record high from low dose nandrolone. The increase from nandrolone lasted long after stopping use of it.

When I stopped TRT for 8 months my hematocrit dropped to 39. Within 8 weeks of resuming TRT at 80mg E3.5D it was back to 48.

Pre-TRT my hematocrit was 46%, now on TRT it is anywhere between 51-54%.

While it's true TRT has a some influence on hematocrit, I would say it appears your body is tightly regulating hematocrit.
