Advice on testosterone values

I’m 40 years old and went to test my testosterone levels. I live in Switzerland so the units of measure from the lab may not correspond to other ways to measure in other countries. My doctor tells me the values are all okay but I’d like a second opinion from you guys: I’ve been feeling low on energy during the past couple of years and my sex drive is not what it once was ;-)

Serum

Androstandiol Glucoronide : 7.06 ug/l
LH (2nd IRP 80/552) : 4.79 IU/l
FSH Abbott (2. IRP 78/549) : 6.56 IU/l
Prolactine (3. IRP 84/500) : 7.41 ug/l
Testosterone Abbot t : 19.6 nmol/l
Testosterone free : 67.0 pmol/l
Sex hormone binding Globulin: 33.4 nmol/l

I’d value your opinion. Thanks in advance.

Answering my own question I found “nomal” reference values for men across different ages spans.

Here’s the chart:

Age 20-29 30-39 40-49 50-59 60-69 70-80
BMI (kg/m2) 23,30 23,97 25,02 25,66 25,54 25,13
T (nmol/l) 22,46 20,45 18,22 16,57 14,20 13,65
mFT (pmol/l) 72,27 63,20 55,73 47,96 38,76 34,80
E2 (pmol/l) 102,90 94,17 90,76 81,02 78,82 80,37
IGF-1 (nmol/l) 29,33 24,35 22,74 20,48 18,02 16,38
SHBG (nmol/l) 45,54 46,20 51,92 55,34 74,21 83,11

So I guess I’m not bad off at all. Oh well, back to the drawing board :-)

Out of curiosity, have you had your blood glucose level checked as well? Either low or high blood sugar will cause a decrease in energy as well as lower libido.

Yes I did - blood sugar was fine as well. Cholesterol was slightly elevated but tryglicerides count were low. My doctor said that my sleep patterns could possibly be the problem - looking into that :-)
