Lots of things yet to consider.
Low 500ís for mid-30ís seems low to me. But there is as yet no labs that show your free t levels. As cat pointed out SHBG is really needed.
The effect of clomid seems potentially promising. The POSSIBLE reason you got emotional as a response was that some of the testosterone produced converted to Estradiol and thus the emotional aspect.
Also the one time you did take Testosterone you seemed to respond positively.
Those two things at least point to the fact that low T and getting properly balanced could help.
Your low body fat would tend to produce less Estradiol. But when taking T or clomid which produced T may cause your Estradiol levels to shoot up. Again SHBG can shed some light on this.
Probably not an issue here but it may also be beneficial to get thyroid labs done. TSH, Free T4 and free T3 as a minimum.
Thanks for your input....SHBG is typically around 40, but for a period last year, it dropped to around 32-33.
I've had my thyroid tested repeatedly for years to try to find the cause of fatigue, and it always turns back ok. Most recently:
TSH 1.36 mIU/L 0.40 - 4.50 mIU/L
T3 FREE 3.2 pg/mL 2.3 - 4.2 pg/mL
T4 FREE 1.3 ng/dL 0.8 - 1.8 ng/dL
Part of me also keeps wondering if my sleep issues are causing this, or the other way around. I've been through sleep studies, sleep doctors, you name it, and the consensus is that I'm just a light sleeper, and that I would benefit from keeping a perfectly consistent sleep schedule (i.e. not staying out late on a Friday). But magically, every one of my friends is able to tolerate that all just fine. So who knows.
Thyroid levels look OK for someone not on any thyroid meds. Free T3 could be up a little but it is 47% of rhe range and the ruke of thumb for someone already on thyroid meds is about 50% to 66%. But like I said for not being on meds your levels are fine in my opinion.
Have you had your cortisol levels checked? Specifically waking response. Recently my daughter had this done (saliva test via a swab). In her case she had a negative waking response. The normal reaponse is that cortisol will increase by about 50% 30 minutes after waking level. In her case her levels DECREASED! She just repeated the morning test (yesterday) to see if this was an random response or is repeated to confirm. Still awaiting the results which should come in today or next few days.
Low cortisol can cause you to be lethargic and not able to deal with stress well.
But I think it is more likely low T. I would expect total T for mid 30ís man to be 650 if not higher. Low T symptoms seem to start for some men around 10. And you are hovering at or below that level.
Thanks for your input - I have had cortisol and ACTH checked twice, last year. One time was lower (but I think done a little later after waking), but in range. The more recent test was fine. I had another endo look over the results, and she was totally comfortable with it. I really thought I'd found something there - but I figure if 3 doctors say it looks fine...
I'd like to believe it's fine as well, as I've always had issues with jolting awake early, overly excited for the day, and unable to sleep any longer.
I definitely felt like garbage last year while in the 400s. Cleaning up on the diet, partying, and keeping to my gym routine helped get me into the 500s again.
Years ago when I first had my T tested, I was working late at a bar 3 nights a week, eating take out, not exercising, etc. And I still hit 590 no problem.
