    Hypogonadal: But With One Test in Normal Range?

    Thanks, Vince. I will look into seeing an Endo. (I had my annual physical the other day, and the GP said it was unnecessary to have a prostate exam. On the one hand I was happy to hear this (!) but on the other I wonder if that protocol applies to those on TRT. I asked the GP about this, and he...

    Hypogonadal: But With One Test in Normal Range?

    Thanks for your reply. Do you think that the lab test of 580 total T after four months of being off TRT was a fluke? 340 seems to be my norm when off TRT, but maybe that's because of relative lack of sleep. I wouldn't mind having 580 as my baseline, although I think the free T level that came...

    I went on TRT in 2012, with one blood test showing total T at 226 (range 350-1150) and a second one a week later at 310 (same range). Because I took these tests a few days after a trip abroad, I wondered if the low results might have been due to sleep deprivation/jet lag. In many ways I felt...

Things started to head south for me when I developed the cervical hernias. I'm not sure if declining levels of testosterone led to getting them, or whether I...

    Testosterone's Protective Qualities on Pain

    Hi Duane, Basically, I have trouble finding words, and I think my memory for them is much worse. I specified "verbal memory" because I don't know if my spatial memory is affected -- I don't think it is. I have always been a very anxious person, but trt has had a huge anti-anxiety effect. This...

    Testosterone's Protective Qualities on Pain

    Test and pain I've had the same experiences. Pain from herniated cervical disks largely went away when I started testosterone, and came back within weeks when I stopped taking it. After three months, I ended up going back on the testosterone because I didn't want to take anti-inflammatories...

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
