Ok I found this:
"The main hormone secreted by the testes is testosterone, an androgenic hormone. Testosterone is secreted by cells that lie between the seminiferous tubules, known as the Leydig cells. The testes also produce inhibin B and anti-Müllerian hormone from Sertoli cells, and insulin-like factor 3 and oestradiol from the Leydig cells."
Wonder how crucial these hormones are in the adult male...
I understand that if you take testosterone replacement therapy (TRT), the testicles can essentially shut down. If this is the case, it might be important to think of everything else the testicles produce (besides sperm).
This is why hCG plays a vital role in TRT. So that you don't have to worry about everything that's affected. The list of things affected by testosterone replacement therapy (TRT) protocols that lack hCG is ridiculous. Personally, if a doctor refused to prescribe hCG, I would instantly start looking for another doc. That's how important it is.
I miss you my brother luv!
I have big...really big things happening.
We need to connect.

Miss ya too man.
I will reach out to you very soon.
Working with Nelson Vergel on a major internet project that will be significant for men's health on many fronts.

Common sense; with the use of exogenous testosterone we in effect are causing a self induced organ shutdown, namely the testes.
The testes do a lot more that just produce sperm.
More important, with HPTA suppression we are shutting down the entire hormonal cascade.
Human Chorionic Gonadotropin (HCG), as an LH analog, does a lot more than just keeping the testes functioning
So what happens when a man testicles don't function anymore do to the lack of LH?
The Biggie: Testicular Atrophy. Men will see their testes get smaller over time and hurt constantly along the way. The duration for this event seems to be different in men where younger guys can seem to go longer where mid to older guys see the event happens on a more accelerated scale. Some think it happens to do with the amount of receptors on the Leydig cells...but who really knows.
Sperm production is pretty much halted.
Men's scrotum's will get really tight and pull up against the body causing pain and end up looking like a 5 year old.
The testes are the single largest producer of the hormone Pregnenolone; the mother of all hormones. We need Pregnenolone for so many reasons and while it can be supplemented it's hit or miss on how effective supplementation can be for some men.
Why we need hCG:
1. To produce Pregnenolone; hCG activates the p450 side chain cleavage (p450scc) enzyme which converts cholesterol to Pregnenolone!!!
2. To produce the precursors for DHEA, Estrogen, Cortisol, Testosterone and DHT...back filling the pathways
3. For proper and normal brain function
4. For proper functioning of the testicles
5. If men ever want to restart
6. If men ever want to have children
7. If men don't want balls that end up in a small mass of useless Collagen
8. The list goes on...
In short, hCG keeps the testicles functioning in a normal state and supports all three androgen pathways. It prevents pregnenolone deficiency and supporting all our other CHOL pathways and hormones as well.
Also, anyone know what labs should be run to see if anything is deficient (besides test and sperm count)?
Not that I'm one to disagree with such a wealth of information being presented, but isn't pregnenolone made in the adrenals? I have no idea how being suppressed due to exogenous testosterone causes this to cease production along with DHEA, although I suspect it has something to do with the negative feedback loop. Could you expand on this by chance? I do take micronized DHEA and pregnenolone as I do not take Human Chorionic Gonadotropin (HCG), but have heard mixed reports on if this is effective or not.
One also needs to consider that we have LH receptors throughout our bodies not just on the receptors on the Leydig cells, including our brain, they are there for a reason.
Without LH and/or Human Chorionic Gonadotropin (HCG) what's not happening...?
^^^ That's my question. What's not happening? Besides natty test...
Is it just pregnenolone that one has to worry about? Is there a convenient lab test out there to check your pregnenolone levels?
