Thanks for that insight. Good to know the results seem ok to you - somewhat reassuring.
As for pulse and energy, it's definitely not right so I'll be getting sugar, thyroid results next week and will post when I get them.
Iron seems to be ok if anemia is presumed a culprit. There is also a penile ultrasound scheduled for next week to assess some pain in the shaft which came from a few nocturnal erections but without ejaculation. Strangely enough, there were times during sleep I awoke to erections but they're not overly pleasant, not quite full but there's a little bit there. Definitely not enough energy to ejaculate or orgasm so I don't even bother. Not much sensation and sometimes they were quite strong and painful.
It's as if the body wants to ejaculate but can't meet the demand because of low energy so the penis will try to get erect repeatedly during sleep but can't go all the way.
So perhaps, thyroid or sugar or something else is an issue. Whatever it is, you're right, I will and am continuing to investigate. It's persistent and hampering my abilities in general.
On another note, despite perhaps not having too much to do with energy (I don't know) what about DHT slightly up, does that mean anything? I have noticed more dry acne, drier skin appear over the last 6 months, would that be responsible since there's receptors to this hormone in the skin?
