QuoteTestosterone: 12 n/mol (Which I was told low-normal)
9.0914n/mol (262ng/dl) is the lower end of the normal range
and 55.2771n/mol (1593ng/dl) is the upper end of the normal range for males.
But that's only the total testosterone count which basically says nothing about the amount of biologically available testosterone (which is usually only 0.7-3.0% of the total testosterone count, depending on gender and other factors).
Relevant is only the free androgen index, which you can calculate yourself if you have data of your SHBG levels at that time (
http://en.wikipedia.org/wiki/Free_androgen_index ).
Normal ranges for the free androgen index are as follows:
sex | age | standard value |
Female | independent of age | <5.5% |
Male | 21-30 | 36-155% |
| 31-40 | 31-116% |
| 41-50 | 21-69% |
| 51-60 | 13-61% |
| 61-70 | 6-49% |
| >70 | 7-45% |
Values below <30%
can cause fatigue, erectile dysfunction and feminization depending on others factors (like estrogen levels and genetic predisposition).
Well... however the free androgen index is still a very error-prone way to measure the amount of free testosterone in the blood for men and is most of the time only calculated for females. Also the data what is FAI standard value can vary greatly depending on the source, so you shouldn't take the table above too seriously.
