G’day ModestoMan,
Some comments based on MY results. I hope they help. All my results are in International Units and not American. To convert European (nmol/L) units to US (ng/dL) multiply the European by 28.57. I think you can work out pmol (10^-12), nmol (10^-9) and umol (10^-6).

I believe that the Total Testosterone normal male population range according to my pathologist is 8.3-29.0 nmol/L. My five most recent 3-monthly results recent results are 41.8, 34.6, 39.5, 39.9 and 50.1, so, I’m off the top of the scale. Your Dad is nearly on a par with me and some might argue is a tad too high. My doctor monitors my blood pressure and skin (blood pressure can go up and you can develop an oily and pimply skin if it’s too high). I’m fine on both accounts – in fact my blood pressure is excellent at 110/65.

You say, “even though Free T is high for his age, it is still low in absolute terms”. However, my Pathologist reckons the normal male Free Testosterone range is 20.0-80.0 pmol/L and I think your Dad is at about 64, which is good. Having said that, my most recent five 3-monthly results are 132.2, 100.4, 84.6, 117.5 and 160.1. He is low compared to that and, maybe, could be a bit higher.

As you say, his FSH and LH are low, as expected, since his brain is detecting the higher hormone levels and not asking for more. My results for both are always >0.5. In the normal male population, my Pathologist says they should be <14 IU/L and >11.0 IU/L, respectively.

As you say, this “is high. Most sources I’ve read say it should be kept below 30. His is 46.6. I suspect this as a reason he’s not feeling better”. I totally agree. According to my Pathologist, Oestradiol: should be <150 pmol/L. My recent results are 141, 127, 144, 110 and 91. As I said in an earlier Post, I suggest Arimidex ASAP. It certainly works for me.

As you say, “SHBG is way high… . amazing how low his free T is, considering how high his total T is. Dad seems to be very good at making SHBG, which isn’t helping”. According to my Pathologist, Sex Hormone Binding Globulin: should be 9-111 nmol/L. My doctor doesn’t always test for this, but two of my recent results are 24 and 21. I reckon the lower it is the better.
Some other tests that I get:
Progesterone: expected range is 0.9-3.9 nmol/L; my recent results are 3.2, 3.3, 3.2, 2.8 and 3.5.
Androstenedione: should be 2.4-13.0 nmol/L; my recent results are 12.6, 12.7, 13.3, 13.7 and 9.2.
Free Androgen Index (FAI): should be 20-120%; two recent results (not always given) are 174.2 and 164.8. FAI is Testosterone/Sex Hormone Binding Globulin x 100. When FAI is below 50, some texts say that symptoms of andropause appear.
I dunno if any of this helps. But there it is.
Cheers,
Rick
