Re: Does high testosterone mean infertility?
Hi Chanel- actually, even though the old lab ranges used to be in the 70's and 80's, the new recommendation is that your testosterone be under 50. My lab range used to be 6-86 and now it is 6-50.
Your free testosterone level does not have much meaning without the units- can you post those? If you could post the range as well, that would be helpful. You should know that free testosterone has a poor assay (not a reliable measurement) and calculating the Free Androgen Index (FAI) is deemed a closer representation of free testosterone levels. The calculation is total testosterone divided by SHBG (sex hormone binding globulin). If your free testosterone or FAI are within range, and even low to the bottom of the range, then I would suspect your SHBG is very high. If that's the case, then it is probably also binding your thyroid hormone. If your have only measured total T3 and T4, then this would not be accurate, since most of the hormone will be bound to SHBG and other blood proteins. If you have your FT3 and FT4, please post it here.
