In my case, I got the results back today from the lab that tested my blood. As expected, my testosterone was flagged as low, at 38 ng/dl. The lab lists normal levels for a male at 241-827 ng/dl, and for a female at 14-76 ng/dl. (Yes, women produce a small amount of testosterone and men produce a small amount of estrogen. Live with it.)
My estrogen was high, of course. Normal for an adult male is listed as 40-115 pg/ml, and less than 40 for a castrate. They also mention that HMG Treatment: Therapeutic is 400-800. Im not sure what HMG stands for, but in any case I am at 397 pg/ml, which is the minimal amount to mostly suppress the hot flashes and night sweats. I still get a few, but they are very mild, and both Donna and I are reluctant to increase the dosage of Premarin beyond its current 2.5 MG daily.
