I'm 60, 5'10", 170, still athletic and fit, gym every day, but increasingly having low-T-like symptoms - mood, energy, and libido/sexual issues. I won't waste your time with the details, but pretty much all the classic low-T symptoms.
Here are my recent 2012 LabCorp test results via LEF (the standard E2 test was used):
Total T ------------ 693 (398-1197) [37th percentile]
Free T - direct ---- 11.6 (6.6-18.1 for age 60+, 9.3-26.5 for age 20-29)
SHBG --------------- 50 (19.3-76.4 for age 50+, 16.5-55.9 for age 20-49)
Estradiol ---------- 16.8 (7.6-42.6)
DHEA-S ---------- 112.9 (33.6-249.0)
Values from August, 2008 test, with no symptoms:
Total T ------------ 763 (241-827) [89th percentile]
Free T - direct ----- 17.1
Estradiol ----------- 21
I've never been on TRT, but have taken a low dose of Arimidex for many years to reduce high (47 originally) estradiol that I believe resulted from taking diltiazem, a CCB, for blood pressure - it worked when nothing else did, but apparently slows down the removal of E2 from the body by inhibiting the relevant CYP-450 enzyme(s). I've tested for E2 every four months, and the dose needed to keep it at about 20 has dropped many fold over the years. The dose which produced the above 16.8 was 1/800 mg per day via very diluted liquid, which is one mg of Arimidex spread over two years.
Total T has dropped from 763 to 693 in the last four years, but because of a change in the range, total T has dropped from the 89th percentile to the 37th percentile, which appears to be a more significant drop. But I don't know if the range change is meaningful, and, you know, it's still 693, which isn't horrible.
What gets my attention is what appears to be low free T caused by high SHBG. While 11.6 looks fairly mid-range for men 60-100 years old, the LEF protocol says I should be in the top third of the range for 20-29, which would be the lower 20's, roughly double where I am now. And Dr. Morgentaler's book says free T below 15 should be considered low if there are symptoms.
But since my total T is 693, the question arises whether I could arrive at a solution by reducing SHBG, which would raise free T. I've been doing a lot of reading, and the possible options I've found are:
1. Do nothing. T is not low. But then, what about the symptoms?
2. Some combination of avena sativa, nettle root, and muira puana to lower SHBG. But I can't find any strong evidence that any of these produce a really significant effect on SHBG, and nettle root in particular has the disadvantage of also reducing DHT, which could be counter-productive.
3. Take DHEA. I've found nothing that shows a reliable effect on either Test or SHBG from doing this. But I believe Dr. Crisler does prescribe it to his patients, along with pregnenolone. Not sure why. Also, I don't know whether my 112.9 is actually low.
4. Take low-dose Danazol to reduce SHBG. Apparently this IS reliable for reducing SHBG (Shippen and perhaps others use this, but not Crisler), but with uncertain side effects, such as reducing total T production. It appears the dose is 20-25 mg per day.
5. Do TRT. My guess is that Dr. Crisler would pick this one. However, I normally get my medical care at the VA, which will take one look at my numbers and tell me to take a hike since everything is within range. So the entire TRT expense of the civilian doctor visits, the meds and the lab tests will fall on me, and I'm concerned that by the time you add up the T-gels and HCG shots, the cost may be prohibitive. So if there's a way to raise free T short of full blown TRT, I'd like to find it.
So I'd like to get everyone's thoughts as to whether the lab results indicate I may have low T, and I'd like to get your opinion on the options listed above, or any others I may have left out. And basically, what do you think I should do?
I do have a civilian doctor that I see occasionally (he charges, and the VA doesn't) but I'm going to ask him to do cortisol and thyroid tests, and anything else that comes to mind, to see if there may be another explanation for the symptoms. But I kinda suspect those will be normal. Recent B12 and prolactin tests have been normal. PSA has been stable at around 1.7 for some time.
Meanwhile I have stopped the near-homeopathic dose of Arimidex for baseline purposes. I did that for six weeks last year, and E2 went up to 26, and I felt worse. I didn't test for T then, but assume it dropped.
Thanks very much for any help.
