And had to do some research in this lately as i thought my estrogen levels were too high, and I came across this. A good read and it shows via age what your levels should be.

"To answer these questions, we can go back to a 2000 Clinical Endocrinology study where they summarized a variety of hormone levels by age, including estradiol:20-29: 102.9 pmol/l
30-39: 94.17 pmol/l
40-49: 90.76 pmol/l
50-59: 81.02 pmol/l
60-69: 78.82 pmol/l
70-80: 80.37 pmol/l
The above are in international units and not the standard pg/ml, so let me do that conversion for everyone reading this in the U.S. (The appropriate conversion factor is 3.671.)
20-29: 28.0 pg/ml
30-39: 25.7 pg/ml
40-49: 24.7 pg/ml
50-59: 22.1 pg/ml
60-69: 21.5 pg/ml
70-80: 21.9 pg/ml
Many of us would guess that estradiol levels would rise as we put on weight with aging, right? However, the data above shows that that is decidedly not the case and estradiol levels to tend to fall as the decades roll by. This is part of the reason that so many men end up with osteoporosis. And making the matter worse is that our SHBG levels climb, leaving us with less free estradiol as we age as well. (SHBG binds to estradiol as well as testosterone.)"
