First off, I want to thank everyone who responded. SSK, I appreciate your professional opinion!
I hear the cautionary notes that many of you are sounding, and I will take them to heart. I know my parents (both Mom and Dad are still with us) will be very cautious about any hormone treatment. But I want to understand the situation better and especially zero in on exactly what the risks of treatment might be, and how they compare to the benefits, especially considering that Dad is heading for a wheelchair, which would have huge consequences for both Mom and Dad and would probably require them to move and make other radical changes.
To put his numbers in perspective, Dad’s total T at 392 compares to a reference range of 90 to 890. The range represents the middle 95% of all subjects tested by that lab. When you consider that hormone tests for men are typically performed only on those complaining of symptoms, one wonders whether that range is really representative of the general population, or rather of the symptomatic population. In any case, 392 is at the low end.
Also, his free T of 40.7 compares to a reference range of 30 to 135. Same comment. I recently read that free T under 50 renders a man functionally impotent, and that no amount of Viagra can help it.
His percent free T is actually off-scale low. At 1.04%, it compares to a reference range of 1.5 to 2.2%. I don’t know how significant the percent number is in predicting symptoms, but it’s striking how low it is.
His LH is at the bottom of the range (3.1 compared to a range of 3.1 to 34.6). LH is the hormone from the petuitary gland that stimulates the testes to secrete testosterone. The fact that it is so low suggests the problem may not be in his testes but rather in his petuitary or perhaps his hypothalmus (hypothalmus senses T in the blood and sends a message to the petuitary to secrete LH if T is too low).
As for Dad’s lifestyle, he hates to exercise but has been doing PT for several years, with little to show for it. We’ve recently gotten him working with a personal trainer. He complains about it, but he does it.
His bone density is actually normal, which is very good since he falls all the time. Maybe it will save him from breaking his hip.
His diet could be better, but it’s really not bad. Mom is a good cook and cooks often. He has 3 meals a day, gets plenty of protein, and takes vitamins. If there’s a problem with his diet, it’s probably too much starch. He loves cookies and cake!
He is on various medications, including blood pressure meds and antidepressants. These could certainly be having an effect. Interestingly, I’ve read that low T can cause high blood pressure, so I wonder whether T therapy might reduce his need for BP meds and have a double benefit. Of course, it might also help him with depression, enabling him to reduce/eliminate the them, as well.
From what I’ve read, the primary risk that discourages most doctors from prescribing TRT is prostate cancer and prostate enlargement. I did some research about this yesterday, and couldn’t find anything definitively linking T with prostate cancer. JAMA published a study in 2006 showing no connection between TRT and prostate problems after 1 year with a small group of study participants (about 50). Many doctors think the connection is a myth, and some even suggest that it is low T that causes prostate problems.
So, I’m still trying to figure out WTF is going on and what the risks might be. We’re not talking about raising his T outside the normal range; the goal would be to increase his free T to normal adult levels.
RickM: Thanks for the link. I read that with great interest and forwarded it to my dad with the note that “this is what a Pro-T doctor sounds like.”
