Serum testosterone, known as ST, is closely related to secondary male characteristics such as body composition, muscular development, growth of body and facial hair, a deeper voice, and so forth.
Testosterone is a primarily male hormone produced by the testes (testicles).
In most cases, levels begin to rise during puberty or adolescence and then remain static from adulthood until about the 30s or 40s, when levels naturally begin to drop due to aging. Buy Testo-Max online here.

In addition to providing secondary male sex characteristics, testosterone is closely associated with sex drive, vitality, energy, the ability to grow muscle, and in some cases, behavior levels.
It is produced by the male testes, and most specifically by the Leydig cells inside the testicles.
But it’s not the testicles that initiate the production or manufacture of the hormone. Rather, this is the responsibility of the pituitary gland, located in the brain.
Another gland is also responsible for its production – the hypothalamus.
The pituitary gland, the hypothalamus, and the testes are all glands found within the endocrine system.
The endocrine system is responsible for testosterone production and release of hormones in the body.
The hypothalamus gland is responsible for maintaining balance or homeostasis in the body in regard to fluids, enzymes, and hormones.
The pituitary gland is responsible for the maintenance and function of all hormone glands found within the endocrine system.
When the hypothalamus gland sends a message to the pituitary gland that testosterone levels are low, the pituitary gland sends a message (through luteinizing hormone) to the testes to increase production.
When this complementary association between these glands is not normal, or one of the glands is defective, a man may experience lower than normal levels. Low testosterone levels (Low T) are defined as hypogonadism.
A number of side effects are associated with low T levels. These include:
If you believe you are experiencing some of the signs of low T, your first step should be to visit your doctor and ask for a blood test that will determine your actual levels.
However, your overall level is often known as your serum testosterone level. The hormone can be broken down into several components:
Total Testosterone (serum) (90%)- This test measures the total levels of testosterone in the blood. Most of the hormone in the blood is bound to two proteins: albumin or sex hormone binding globulin or SHBG.
Approximately 38% of bound testosterone is attached to albumin, while approximately 60% is attached to the sex hormone binding globulin, also known as sex steroid binding globulin or SSBG.
Free Testosterone (1% to 4%) – This is defined as test in the blood that is not bound to sex hormone binding globulin (SHBG) as is the bulk of testosterone in your blood is.
A number of tests are useful in determining different levels of the hormone (total, free, and bioavailable).
Many of them are simply blood tests. Other tests that may provide a more specific diagnosis will include:
Talk to your doctor if he has recommended any of these tests to determine whether you are indeed dealing with low T levels. Levels vary depending on age, but most men average 300 mg per deciliter to 1,000 mg per deciliter.
Of course, even these figures may vary. Contributing factors such as age, health status, and exercise levels, diet, and lifestyle (such as drinking or smoking) can have a huge impact on testosterone levels.
If you are experiencing any signs or symptoms of low T or believe you are, schedule a visit with your doctor.
If it is determined that you may be a bit low, depending on otherwise normal ranges, or you’re experiencing some of the side effects associated with low T levels, your doctor may recommend several steps to improve serum testosterone levels.
The first will be changes in diet and exercise. Changes in diet may include any increase in foods that provide high levels of nutrients that support pituitary gland function.
A number of test boosters or supplements on the market today that are over-the-counter and don’t require a prescription contain a number of vital nutrients including herbal ingredients, vitamins, minerals, enzymes, and amino acids that can increase serum testosterone levels.
