This lab was my first check of Estradiol and occurred just before I started the aromatase inhibitor Arimidex to control this strongest estrogen in men. I had just started Testim 5g/day with no HCG. Estradiol is also known as E2 and is blamed often for libido and erection issues. There is a great deal of talk about Estradiol needing to be at a certain “sweet spot” often reported as around 25 pg/mL. In this lab my value is 82 pg/ml, which is high given the lab range reported for men as less than or equal to 29 pg/mL.

Note the really important lesson here is twofold. First, the “sweep spot” theory is just that – a theory, and a bunk one at that. While it may be true in some men, and at the time of this test I thought I found the cause of my own libido issues, later when my levels were steady at a number greater than 82pg/mL functioning and sexual appetite were more than just fine. My sweet spot seems to be a range that is not too high (what that number is I do not know) or too low. Second, the real metric of interest is a stable level that is not bouncing around all over the place.
