What is Testosterone? And how is Testosterone made?
I could write a very scientific article about Testosterone but that would not really serve a purpose here, since me and most of my readers are normal people – not scientists. Try to ask a scientist “what is Testosterone?” and you will be most likely more confused than you were before!
Because of that I will write this post in a way that is very easy to understand so you can get all out of it. And hopefully after reading this you have a clear image on your mind about: What is testosterone? And why would I need to increase it?
What is Testosterone? And why i need it?
Testosterone is the king of androgens (male hormones) and it’s produced mainly in the male testicles. Production of Testosterone is controlled by the brain’s hypothalamus and also the pituitary gland. Testosterone is the principal male sex hormone and an anabolic steroid. (Don’t worry we’re talking about natural “anabolic steroid” now, it has nothing to do with synthetic injectable drugs that will destroy your body.)
1. Something activates your androgen receptor
2. Free Testosterone is transported to target tissue cell
3. Testosterone binds to the androgen receptor
4. Now the receptor goes through a structural change making it able, to enter DNA
5. Once it’s bound in DNA, it alters certain genes producing the androgen effects (masculine characteristics)
Now a very important thing to understand is that the male hormone Testosterone, and the female hormone Estrogen fight for the same receptors.
In a nutshell, this means the following: If Testosterone get’s in the receptor, then you will get masculine effects (in a long term this would mean beard growth, wide shoulders, big adams apple, increased muscle volume etc.) but on the other hand, if the female hormone Estrogen get’s there first you’ll get feminizing effects like for example man boobs, increased body fat, muscle athropy, erectile dysfunction, etc.
Because men normally produce 20 times more testosterone than females, it’s the extra testosterone in the male body, that makes it much easier to build muscle. It’s also Testosterone that makes men have lower levels of overall body fat than our female partners.
Starting to understand what is Testosterone?
Great, However there’s much more, so let’s continue on the subject of, what is Testosterone? And what effects it has on the male body. See, Testosterone has some very favorable benefits after it reaches those receptors. Here is a small list of some of them:
- Increased growth of facial hair
– Increased libido
– Increased erection frequency
– Subcutaneous fat in face decreases
– Increased muscle strength and mass
– Deepening of voice
– Growth of the Adam’s apple
– Growth of jaw, brow, chin, nose, and remodeling of facial bone contours
– Shoulders become broader and rib cage expands
– Every single masculine trait in you will grow more significant
– Feminine traits will vanish
That list would go on for days, but the point here is that everything that you probably consider masculine is caused by high Testosterone levels. That’s why it is the main male sex hormone!
So are we done with the subject? Do you know now what is Testosterone?
No! We ain’t done yet! We still have to figure out how the building blocks in your body are made into Testosterone!
1. Hypothalamus inside the brain detects that now we need to make some T
2. Hypothalamus secretes gonadotropin-releasing hormone (G-rH)
3. G-rH goes straight to the pituitary gland (which is also located inside the brain)
4. The pituitary gland then produces a) follicle-stimulating hormone (FSH) and b) luteinzing hormone (LH)
5. LSH and LH get in to the bloodstream and through our veins they finally reach their destination, testicles
6. Inside the ballsack LH will stimulate the leydig cells to produce Testosterone and LSH will jumpstart the sperm production process
7. Through a complex process our testicles Leydig cells will start to convert cholesterol into testosterone
8. Testosterone get’s back into the bloodstream and is now ready to bind into a receptor!
Now above you can see that CHOLESTEROL converts to Testosterone. That’s the reason you should eat foods contain cholesterol, because it is vital for your brain, heart, and sex hormones! I will post more articles about fat and cholesterol later on but right now you have to know that it is actually a good thing to eat fat and cholesterol, contrary to what you have been told!
