It was admittedly awkward, but the doctor was extremely professional. It's hard to treat a biological sexual disorder without objective measures. This is an objective measure, and knowing that made the test seem appropriate however awkward. If you aren't having any sexual dysfunction, I'm not sure the test I had is really necessary. Maybe just check for varicocele only. Anyway, they found that my blood flow (cardiovascular health) was poor. Low testosterone certainly is a factor in that, but everything is related: Low T -> low energy/drive -> less active/fatigue -> carb/sugar/fat-heavy diet to compensate for low energy -> weight gain/obesity -> elevated lipids and blood pressure -> increased conversion of T to estrogen from aromatase in excess fat -> Low T and back around again - you could add sleep apnea and sexual dysfunction in there as well as both consequences and contributing factors. Ultimately, there is a strong correlation between poor circulation in the penis/ED and heart disease. My doctor said my readings would have been alarming for an 80 year old man let alone a 35 year old one. He said we had to treat the low T and improve cardiovascular tone with diet and exercise. He also found my E2 was at 88 which was masking any benefit of TRT, so he wanted to manage that with an AI. I've been back to see him since, and I show much improvement from the baseline test. So - worth the trouble and awkwardness in my opinion.
