Endocrinologists: i'm a 34 y/o male. labs for testosterone (free+total), estrogens total, & estradiol were w/in reference interval. but estrone serum result was marked as high (83 pg/ml for a 12-72 pg/ml reference interval). is this concerning?

Borderline high: Since your estradiol level was normal, one can't be sure of the significance of a slightly elevated estrone level although one study suggested that it may be a precursor of type 2 diabetes in men. ?of whether it would affect libido or erectile dysfunction. An endocrinologist is best qualified to answer your question,however. Perhaps repeating the test is worthwhile.
