    Do I Have Primary Hypogonadism ?

    Do you suggest that over really low-dose clomid (12.5mg EOD)? The serious side effects became really pronounced when my Dr in response to the above labs doubled my dose to 25mg OD (instead of EOD). I wonder if taking a step back and giving more time would be more prudent as opposed to HCG due to...

    Do I Have Primary Hypogonadism ?

    TT was at 250 like 4 years ago. Unfortunately didn't get initial LH/FSH readings. I had terrible side effects so I got off clomid, but I wonder if I push through for another month or so that my testes will "wake up". Things have obviously flatlined after stopping the Clomid. This is very...

    Do I Have Primary Hypogonadism ?

    Was on 25mg Clomid EOD. After 4 weeks I did labs and had these results: LH: 7.5 (1.7-8.6) TT: 330 (264-916) Does this mean I'm primary or is 4 weeks not enough time for the testes to recover? I was using HCG while on TRT, but obviously not frequently enough. I was simply doing 250iu 1-2x/week...

    Pregnenolone – By Gene Devine

    Thanks for the tip! They happened to run a Progesterone lab, too, and it was also 0 (undetected). I'm going for an ACTH stimulation test, I've had low cortisol values, too. Curious how this pathway could create secondary hypogonadism, but wouldn't be surprised.

    Pregnenolone – By Gene Devine

    I had labs that show no detectable (0) pregnenalone as well as progesterone with a DHEA-S level of 194.0ug/dL (0 - 650). This was while I was on TRT (on clomid now without much success - high LH, low T...). Wondering why (as far as I can tell) there isn't much research in men on...

    1 month in on PCT - High LH, Low T

    Serum T: 330 (265-916) E2: 5.6 (7.6-42.6) LH: 7.5 (1.7-8.6) SHBG: 21.6 (16.5 - 55.9) Labs taken a couple days ago. I've been on TRT for ~3 years. I was thrown on TRT before I could have LH/FSH measured. I never felt much better on TRT and want to investigate the underlying issue. I typically...

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.
