My Lab Results - Seeking Advice

I’m not on TRT and I’ve never messed with my hormones.

I’m currently 38 years old and I’ve felt a decrease in motivation, energy and I’ve felt generally tired over the last year.

My sex drive has always been very high, but I have definitely noticed a decrease as well.

I requested to have my SHBG tested, here are the results:

Total testosterone - 860 ng/dl (300-1080)

SHBG - 72 nmol/L (11-80)

Bioavailable Testosterone - 316 ng/dl (131-682)

Free Testosterone- 102 pg/ml (47-244)

Percentage Free Testosterone - 1.2% (1.6-2.9)

My Endocrinologist said everything is great.

I wish I would have tested everything when I felt “great” to compare because I feel that my SHBG is high. She states that “we don’t shoot for a specific level of SHBG and your free testosterone level is good so there isn’t an issue. Your symptoms are not related to these levels”.

Can someone with experience give me your opinion.

Appreciate the help, thanks for your time.

You’ll need to add the lab ranges to your post, different labs have different ranges so in order to see the full picture we need the ranges

Just edited to include that.

Your free T could be better. Taking TRT tends to lower SHGB too which would help raise your free T. Problem is your total T is pretty high so you probably won’t find a doctor that will prescribe you

I’ve been reading a lot on Boron. Any experience with it lowering SHBG?

I’m already supplementing Vitamin D3.

I eat 1.5 cups of Quaker Oats every morning since I was a teenager. I get a lot of fiber and I read fiber can raise SHBG. Any thoughts on that?

I take boron. Won’t make much of a difference for your shbg. Not enough to matter

Why do you take it?

Maybe this will help:

Boron helps with the absorption of magnesium amongst other things. Most people would benefit from supplementing boron.

Normal FT percentage is 2-3 and your endo is clueless and probably has zero education in sex hormones (very common) or what constitutes normal free testosterone percentage. Your endo clearly only paid attention to the TT value, classic and very common because he more than likely doesn’t understand the other stuff.

Your FT percentage is low because SHBG is astronomically high, SHBG isn’t something you have a great degree of control over, TRT is the only thing on earth that is going to make the biggest dent. If you’re thinking about lowing SHBG naturally enough to matter, good luck because it’ll never happen.

You went to a doctor that specializes in thyroid and diabetes and not sex hormones, there currently is no specialty doctor in managed healthcare that specializes in TRT, it is optional and most elect not to because of all the false studies showing cardiovascular risk and prostate cancer in men on TRT.

You can continue to play the doctor lottery or you can seek a private TRT specialist that prescribes TRT everyday and went to the proper medical school and receive sex hormones education with the intention of prescribing testosterone on a regular basis (Anti-Aging/Sports Medicine) and not only when a guy comes in as a referral within a healthcare network.

My email is in my bio. Email me and I’ll hook you up with a doc that may be able to help you. He prescribed me at 600 total T

Doesn’t SHBG fluctuate based on environmental factors? Lack of sleep, overtraining, not eating enough, lack of carbs, etc.?

It seems silly to base everything off of 1 test. It seems like multiple tests would show more and eliminate the possibility of errors in testing.

SHBG levels do fluctuate, exersise and it increases, but you don’t have a great degree of control, you would have to become obese and insulin resistant (diabetes) to lower SHBG to a large degree.

Once SHBG gets into the 40’s, it starts negatively affecting FT levels. The only way to affect SHBG the a large degree is TRT and even then there are no garrenties, every so often a guy comes along and his SHBG wont budge no matter how much androgens he throws at the liver.

Isn’t the percent of FT irrelevant because everyone’s total testosterone is different?

According to Quest Diagnostics, males between the ages of 20-39 have an average Free Testosterone level of 10.75 ng/dL.

Mine is at 10.2 ng/dL.

So it seems like the percentage is irrelevant.

Directly measured FT has problems, it’s inaccurate and why your doctor fixated on TT, he knows FT is problematic. The TT and SHBG when using the appropriate calculator, FT percentage needs to be 2-3 preferably on the higher end when SHBG is astronomically high.

FT percentage is more accurate than any FT direct measurement. SHBG balances TT and FT, more TT, less FT in circulation, TT is not bioavailable, only FT is the active hormone and your percentage is below normal.

It was a big blunder that he missed the 1.2 percent FT. He probably doesn’t want prescribe TRT in the first place place, most refuse to discuss TRT.

Think about it for a second, you went to a managed health care doctor looking for TRT which is steroids, it is a taboo subject and demonized in western medicine and has negitive politics attached to it.

You should be looking for TRT in anti-aging or sports medicine, not manage health care because most of the doctors are clueless.

Your SHBG levels are actually abnormally high if we go by Labcorps ranges which top out at 54 nmol/L, managed health goes strictly by the number and ignore the symptoms. The only thing we should pay attention to is TT, SHBG, FT percentage and ignore directly measured FT because the latter is inaccurate.

Let’s take what we know about SHBG’s function, it binds androgens so the higher the SHBG, the lower the free hormones and the more is deactivated and bound to SHBG. Sure high SHBG is healthy, but not if we let it run wild binding up too much testosterone.

The truth is I have never to date seen a guy feeling awesome with TT high normal and SHBG abnormally high, has never happened in the 3 years I’ve been visiting T-Nation and Excelmale 6 days a week for hours per day.

You can have a look at other members threads and see a trend, guys are having problems with lower TT and SHBG in the 40’s which is when SHBG starts negatively affecting FT. Also there is a variability in the binding force of SHBG between individuals, some men have SHBG that binds androgen weakly and other very strongly.

I once saw a guy with an SHBG at 32 and his FT percentage was dreadfully low, it was as if his SHBG was triple the stated value when compared with other members. If you were to take a single blood sample and send it to more than one laboratory for testing, you would get different results on each test, this is where we are today, lab testing has a lot of room for improvement.

Challenges in Testosterone Measurement, Data Interpretation, and Methodological Appraisal of Interventional Trials

Several factors impact measured T levels including aging, circadian rhythms, geography, genetics, lifestyle choices, comorbid conditions, and intra-individual daily variability. The utility of free T (fT) over total T is debatable and must be compared using appropriate threshold levels. Among various assay techniques, mass spectrometry and equilibrium dialysis are gold standards. Calculated empirical estimates of fT are also commonly utilized and accepted. Hypogonadism-specific questionnaires have limited utility in screening for hypogonadism, and their role as objective end-points for quantifying symptoms remains unclear. Numerous aspects of study methodology may directly or indirectly impact reported outcomes including design (randomized, prospective, retrospective), duration, populations studied (age, comorbid conditions), low T threshold, therapeutic agent utilized, objective measures/end-points selected, and statistical interpretation.

Is thyroid stimulating hormone related in any way to affect SHBG or free testosterone levels?

I know hyperthyroidism is associated with high SHBG but my thyroid stimulating hormone is on the high side which would be closer to hypo, not hyper.

Any idea what your H1C or glucose levels are?

The only glucose test I’ve done was self administered which came back normal, what exactly I don’t remember.

My TSH was 3.7 uIU/mL (0.4 - 4.2 uIU/mL)

I also had my AM cortisol tested, not sure if it has any relevance to SHBG and free testosterone.

15.1 ug/dL (8.0 - 25.0 ug/dL)
