Serum testosterone level decides secondary male characteristics like body composition, muscle development, body and facial hair and deeper voice etc. This is also known as male hormone that is produced by the testicles. The level of hormone rises during teenage and remains almost static till the age of thirties and forties. After that it starts declining, due to age.
Serum testosterone levels
Testosterone besides providing secondary male characteristics is also associated with sex drive of male, energy, vitality, and ability to grow muscles. It also affects the behavior pattern, too. However, you have to understand that testicles are not accountable for production of testosterone but it is the responsibility of our pituitary or master gland that resides in our brain. There is another gland known as hypothalamus that is also responsible for production of testosterone. All these glands are found in our endocrine system. This endocrine is mainly responsible for testosterone level that releases hormones from the body. Another gland called hypothalamus gland that is responsible to maintain balance in the body with regards to enzymes and fluids.
When T-level decreases hypothalamus sends signal to pituitary gland, which in turn signals the testicles to produce more testosterone and does not differentiate between bound and unbound testosterone. In case one gland becomes defective then man may feel low level of testosterone. Lower level of testosterone may result into the following.
- Erectile dysfunction
- Lower sex drive
- Lower sperm count
- Mental and emotional distress like mood swings, depression or anxiousness.
- Body fat increases
- Decrease in muscles mass
Testosterone level with blood test
In case you feel low testosterone level then visit a doctor and request him to get your blood tested so as to determine your actual level of testosterone. This is known as serum testosterone level. It can be broken into many different components. The serum testosterone indicates your total testosterone level. About 38 per cent of testosterones are related to albumin and 60 per cent testosterones are related to sex hormone. Rest 1 to 4 per cent are free testosterone which has nothing to do with sex hormones.
There are many other tests available to determine different levels of hormones present in our body. They are as follows:
- Follicle stimulating hormone
- Luteinizing hormone
- Sex hormone binding globulin
These blood reports can be explained in details, by your doctor.
