What Is Testosterone?
Testosterone is an important hormone found in humans, as well as in other animals. In men, the testicles primarily make testosterone.
The production of testosterone increases significantly during the years of puberty and begins to dip after age 30 or so. In some men, this dip in levels can be substantial. For example, we’ve seen that around 19 to 39 percent of older men may have low testosterone levels.
What is testosterone's role?
Testosterone is a significant sex hormone in males and plays many essential roles though your lifetime, such as:
- The development of the penis and testes
- The deepening of the voice during puberty
- The appearance of facial and pubic hair starts at puberty; later in life, it may play a role in balding
- Muscle size and strength
- Bone growth and strength
- Sex drive (libido)
- Sperm production
Testosterone can help maintain a normal mood.
According to Testosterone – What It Does And Doesn’t Do, published by Harvard Health, Signals sent from the brain to the pituitary gland at the base of the brain control testosterone production in men. The pituitary gland then relays signals to the testes to produce testosterone. A “feedback loop” closely regulates the amount of hormone in the blood. When testosterone levels rise too high, the brain sends signals to the pituitary to reduce production.
Low testosterone, or testosterone deficiency (TD), can occur when there is a problem with the testicles or the pituitary gland, responsible for stimulating the testicles to produce testosterone.
Symptoms of Low Testerone
Several signs and symptoms can point to low testosterone levels. These symptoms can vary from person to person. They may develop slowly or suddenly. Some are closely related to low testosterone levels (specific signs and symptoms). Although, others may not necessarily be linked (nonspecific signs and symptoms). At Revive Wellness of Oxford, our professionals can help you understand your situation.
Specific Signs/Symptoms of Testosterone Deficiency (TD)
Several particular signs and symptoms can be associated with TD, including:
- Reduced sex drive
- Reduced erectile function
- Loss of body hair
- Less beard growth
- Loss of lean muscle mass
- Feeling very tired all the time (fatigue)
- Obesity (being overweight)
- Symptoms of depression
The nonspecific symptoms are those that may or may not be linked to TD, such as:
- Lower energy level, endurance, and physical strength
- Poor memory
- Difficulty with finding words to say
- Poor focus
- Not doing well at work
If you’re experiencing any one of the specific or nonspecific symptoms mentioned above, it may not mean that you have a testosterone deficiency. But if they are mixed, for instance, a change in your mood and energy levels over time which is different from how they used to be – this could point towards testosterone deficiency.
Suppose you’re only experiencing a low sexual drive alone; that may not mean that you have a testosterone deficiency. Although if you have a combination of low sex drive, reduced erectile function, and feelings of exhaustion and sadness, you should talk to us to find out what’s going on!
