Age 38 when began to loose sexual function. (not simply e.d., desire, thoughts, craving, and penile sensitivity) HRT for two years benifitted many things but not sexual function. So far I have only been able to test for total testosterone (220) complete estrogen (estriol was high but was told E2 is more important) cortisol, thyroid. I am 40 now and have almost competely diminished labido and my genitals often feel like a finger or any other non sexual organ. I have a few good days now and then its all great but the next few days I have zero interest and no feeling and this in the past two years have went from never having a problem to almost zero overall with fewer days I can enjoy sex at all. This is NOT phycoiogical and I never took anti depresants. The only thiing I ever took was meth but the problems never showed up until months after I got sober and healthy. HRT no matter what levels for how ever long do not effect the main problem. Please tell me which test I can take that might find the answer. I am adding psa, proactlan, ensulin resistence, and all the basic things but would like to know of anything I should add that might solve this thanks.
