Testosterone is the primary sex hormone produced in male reproductive organs. Testosterone is an important hormone in men for sexual development and functions. Testosterone production is high during puberty and starts to decline after men reach the age of 25. It increases until the age of 25 and decreases at 2-3 percent each year. Testosterone is mainly associated with optimal sperm production and sex drive. It also develops secondary characteristics like bone mass and muscle mass. Testosterone even helps in red blood cells production.
Importance of Testosterone
Testosterone plays a vital role in developing sexual characteristics. In addition, it plays a vital role in:
1. Developing bone and muscle mass and decreasing the amount of fat in our body:
Testosterone increases neurotransmitters which, in turn, encourage tissue growth. Testosterone also increases the level of growth hormone. Dropping levels of testosterone often leads to an increase in body fat.
2. Growing pubic and facial hair:
Testosterone is produced in large amounts during puberty and leads to hair growth on the face and armpits. Testosterone also affects body hair present on other parts like legs, hands, and chest.
3. Develops sexuality through deepening of voice and development of other sexual characteristics:
Testosterone plays an essential role in developing sexual organs in men. It also helps in developing secondary characteristics like growing sexual desire.
4. Low testosterone is a common problem in aging men:
This is completely natural as testosterone depletes as you age. However, low testosterone levels cause issues like low sexual drive or accumulation of fat in the body.
Benefits of Optimal Testosterone Levels
1. Healthy Heart and Blood
A healthy heart is necessary for the good health of other organs. The heart pumps blood to different organs of the body and helps them in achieving optimal performance. Testosterone is helpful in red blood production through the bone marrow. Testosterone spurs the bone marrow and increases blood production. Many studies prove the positive effect of testosterone on our hearts.
The higher production of red blood cells means better oxidation throughout the body. Red blood cells carry hemoglobin, which is the major oxygen carrier in our body. However, there are conflicting results on the effects of testosterone therapy on our hearts. Testosterone therapy by intramuscular injections has a positive effect on the blood cells. Its side effects even cause increased red blood cell count. On the other hand, a recent study showed that testosterone causes changes in cholesterol levels.
2. More Muscle and Less Fat
Testosterones are important for increasing muscle and bone mass. A leaner body has better control of weight and lower fat levels. It is common for older men to lose muscle and bone mass due to lower testosterone levels. Many athletes also take testosterone to have lower body fat and increased bone mass. However, testosterone treatments only offer a leaner body shape. To increase strength, you should pair testosterone treatments with training and exercise.
3. Stronger Bones
Testosterone also helps increasing bone density. Bone density decreases with age due to lower testosterone levels. This leads to weaker bones and osteoporosis. Optimal levels of testosterone help maintain strong bones, which leads to higher strength. Trials on the effect of testosterone on bone density found an increase in hip and spinal bone density. Men with optimal levels of testosterone have lower chances of bone fracture. Stronger bones also better support your internal organs and increase athletic performance.
4. Better Libido
Lower testosterone levels often lead to poor sexual performance and arousal. Testosterone levels rise as a response to arousal or sexual activity. Older men with lower testosterone levels often have worse sexual performance and arousal. Now, a decrease in testosterone levels is not the only reason for Erectile Dysfunction. ED can be caused by a multitude of reasons and medical conditions.
Many studies have shown the positive effects of optimal testosterone levels. Many testosterone treatments also lead to better sexual performance. However, there is a limit of testosterone, after which there aren’t any noticeable changes. For men who don’t have hypogonadism, increasing testosterone levels provide no benefit for libido.
5. Improved Mood
Testosterone affects some aspects of our behavior. Men with lower testosterone often have a poorer quality of life. Some symptoms of low testosterone levels include depression, fatigue, and irritability. Low testosterone levels may even cause a lack of motivation and loss of confidence. Testosterone plays an important role in controlling some aspects of our behavior.
Optimal testosterone levels result in better aggression and dominance. Taking part in competitive activities also affects testosterone levels. Thus, higher testosterone levels lead to better motivation and confidence. It is worth noting that men having a natural decrease in testosterone don’t have any effect on their behavior. Testosterone levels are one aspect of behavior and don’t define it completely.
6. Better Brain Function
As Testosterone levels decrease, it takes an adverse effect on brain function. People with low testosterone levels lose their initiative, sense of wellbeing, and self-confidence. They also lose their drive, goal orientation, among other qualities. Optimal testosterone levels result in better spatial cognition. Testosterone also increases memory and concentration. Men with optimal testosterone levels perform better in cognitive tests. Thus, testosterone does play a role in increasing brain function and cognitive function.
Testosterone is the primary sex hormone in men. It is the major hormone needed for primary and secondary sexual development. Therefore, optimal testosterone levels are essential for the better health of men. Testosterone performs many functions like the growth of facial hair or the production of red blood cells.
Optimal testosterone levels also result in stronger bones and muscles. Often better sexual performance is associated with optimal levels of testosterone. It’s fair to say that there are many benefits to having optimal testosterone levels. The benefits range from better sexual performance to higher brain function.
