Well, I already have another topic here but this one will be more specific in free testosterone
Makes about 7 months I with erectile dysfunction, difficulty maintaining an erection (I can not keep the penis TOTALLY hard without cialis)
and my exams were:
TESTOSTERONE TOTAL: 1009ng / dl
Albumin: 5,11g / DL
SHBG: 49,7nmol / L
I believe that despite my total testosterone be good / high without using any steroid, SHBG is stealing my free testosterone and preventing my erection, what do you think?
I used an online calculator (Free & Bioavailable Testosterone calculator) to calculate my free and bioavailable testo and according to my doctor the minimum of “free testosterone” should be above 2% and my resulted in:
Free Testosterone = 17.3 ng / dL = 1.71%
Bioavailable Testosterone = 478 ng / dL = 47.4%
Because I am using using some vitamins / MINERAL / etc and anastrozole 0.25mg / day (no, not much if that’s what you will ask me … because I used this procedure for 15 days and did estradiol examination and resulted in 22, but used for another 15 days (with stop) sAME dOSAGE and redid the estradiol examination and gave in … 44, ie, with the same dosage increased my estradiol rather than decrease more)
my new lab result was:
TESTOSTERONE TOTAL - 908 ng/dl
SHBG - 36.4 nmol/l
Albumin - 4,0 g/dl
and based on these new numbers I noticed an improvement in my ability to maintain an erection without cialis
Free Testosterone = 21.3 ng / dL = 2.35%
Bioavailable testosterone = 467 ng / dL = 51.4%
If I down my SHBG, especially lowering estradiol with IA, and have more free testosterone probably my problem go away?
