Testosterone is an androgen (a male sex hormone). Testosterone is a naturally occurring steroid hormone. It is considered to be the “male hormone” although women’s ovaries produce some testosterone. The hormone is produced in much higher concentrations in men and is responsible for Development of male genitalia (in the fetal stage).
The brain and pituitary gland, a small gland at the base of the brain , control production of testosterone by the testes. From there, testosterone travels via your blood to do its work. Small amounts are also secreted by the adrenal glands.
In general the androgen “testosterone” is recognized as the male sex hormone and is responsible for having anabolic effects such as being responsible for promoting protein synthesis and stimulating development of male sexual characteristics in addition to contributing to a healthy libido, building muscle mass, bone maturation and maintaining energy levels.
What are normal testosterone levels
Even though I believe its not something you should fear if you are wise about your hormonal health but research shows that T production starts declining from the age 30 reducing around 1% per year.
A simple blood test can determine testosterone levels. There is a wide range of “normal” or healthy level of testosterone circulating in the bloodstream. The normal range of testosterone for men is between 250 and 1100 ng/dL for adult males,
This chart is created by using the statistics of the Mayo Clinic:
Don’t stress about declining testosterone levels this is because most men don’t experience their potential testosterone levels. This is not your fault but just a lack of education. Lets say in your 20’s due to poor lifestyle choices and unhealthy living your testosterone levels average was around 300-500dl . Now what happens if you are in your 30’s and follow advice on this website on how to boost T production. You could jack up your average of testosterone levels up to 800-1070dl . Now if you did this would it be really relevant if science says your testosterone production is meant to decline one 1% every year when you reach 30,
Not really, Ideally you should actually feel healthier more masculine in your 30’s or even 40’s. This is only possible if you take optimizing your testosterone levels seriously. This website will provide you with the tools and knowledge so don’t ignore it.
Types off testosterone
There is Testosterone that is bound to proteins in the blood (e.g., albumin and sex-hormone binding globulin [SHBG]) as well as testosterone that is not bound (free testosterone).
Free testosterone only makes up to 2 – 3 % of your testosterone. It is named “free testosterone” because it is not connected to any proteins. Free testosterone flows throughout the body and can activate receptors. Androgen receptors can be activated by various ways such as physical stimuli. For example doing a shoulder press exercises can activate the androgen receptors in your shoulders which then allows free testosterone to bind to the receptors. Allowing free testosterone to enter your DNA and work its anabolic magic.
Testosterone-binding globulin or sex hormone-binding globulin (SHBG) testosterone
Sex hormone-binding globulin (SHBG) comprising between 40-50% of your total testosterone and is a protein that binds together with testosterone molecules. SHBG-testosterone is your most prolific testosterone, SHBG-bound testosterone can be carried throughout and can be easily detached creating more free testosterone.
Some vital functions of Testosterone
Testosterone also plays a role in fat metabolism, helping men to burn fat more efficiently. Dropping levels of testosterone can cause an increase in body fat.
Testosterone serves as a catalyst for protein synthesis, thus the higher the testosterone levels are, the greater the effect of protein synthesis. It is simply impossible to develop lean muscle mass without this process. Testosterone production is also closely tied to growth hormone production, both playing a major role in muscle development. That makes exercise more likely to build muscle.
Testosterone contributes to an active sexual drive in both men and women. Sex drive is influenced by biological, psychological and social factors. Biologically, the sex hormones and associated neurotransmitters that act upon the nucleus accumbens (primarily testosterone and dopamine, respectively) regulate libido in humans. Low testosterone is also linked to erectile dysfunction.
Testosterone increases bone density and tells the bone marrow to manufacture red blood cells. Men with very low levels of testosterone are more likely to suffer from bone fractures and breaks.
Experiencing low testosterone levels can be a sign of not living a healthy lifestyle and neglecting your health. Some signs of having low T are:
- Reduced libido
- Reduced sperm count
- Hot flashes
- Increased breast size
- Impotence or erectile dysfunction
- Shrunken testes
- Reduced muscle mass
- Hair loss
- Increased propensity to bone fracture
In men with hypogonadism, a low level of testosterone is produced due to a problem in the testicles or the pituitary gland. Not sure if you have low T then check out this post (10 signs you have low testosterone and libido levels).
Testosterone plays a great role in muscularity characteristics and sexual development. There are many contributing factors responsible for testosterone production. In theory testosterone levels should start declining in your 30’s but in general most men don’t reach their testosterone levels potential therefor men can always increase there testosterone levels as they age. This can be done naturally and TRT should be the last option (Testosterone Replacement Therapy Risks And Side Effects). Visit our testosterone section to learn how to boost T production naturally.
