How Does Testosterone Impact our Bodies

Most of us know testosterone as the male hormone, and in recent years, the chatter surrounding it has been quite loud, especially in the fitness industry.

While most of us know that testosterone is important, many of us struggle to explain why. Well, due to this, we decided to try and explain testosterones role in both male and female bodies in as simple terms as possible. If this sounds interesting, read on!

What is testosterone?

Testosterone is a natural anabolic steroid and is considered to be the male sex hormone. However, this doesn’t mean that women have nothing to do with testosterone. They produce it as well, and it plays a crucial role in their bodies too. Let’s take a look at the different ways testosterone interacts in male and female bodies.

Testosterone In Male Bodies

In male bodies, testosterone is primarily produced in the testes. During puberty, testosterone production is increased, and this increase is actually what causes changes in the male body. It impacts voice change, body-hair growth, bone density, and muscle growth and is responsible for the active sex drive in the teenage years. Throughout a male’s life, testosterone levels impact many things related to the body’s proper functioning. Lack of testosterone can cause many mental and physical issues, including:

It should be apparent how big of a role testosterone plays in male bodies and why it is important to keep it at appropriate levels. The situation becomes even more alarming if we take into consideration the fact that T production tends to drop off after the age of 35. The rate of the drop-off is around 1% per year, but the number can vary depending on a person’s lifestyle.

Proper testosterone levels ensure optimal bone density, muscle generation, and fat distribution, all factors being essential to anyone aiming for an athletic body.

Testosterone In Female Bodies

Women also produce and benefit from testosterone. Their optimal testosterone levels are different than in men as they are significantly lower. It doesn’t regulate as many things within the body but has an important role in several important functions. One is the repair, growth, and maintenance of the female reproductive tissue, which is a very big deal. On top of that, it also regulates mood and ensures healthy bone mass.

The role of testosterone in body function

Muscle development

This effect of testosterone is tied to its anabolic capabilities. The way testosterone helps with muscle development is through the promotion of protein synthesis in our bodies, giving your muscles more “building blocks” to grow. It also impacts our overall strength, so it’s very useful to have high testosterone levels if you are exercising regularly. It’s worth noting that even if you have high testosterone levels, muscles are not going to grow by themselves — they need exercise too. It combines very well with resistance training which is also known to raise T levels.

Fat regulation

We once considered fat cells to be nothing more than dormant storage spaces our body uses when it’s energy deficient. Unfortunately, this isn’t true, as fat tissue acts like any other organ and sends signals impacting how our body functions. The biggest issue with fat is that it produces an enzyme called aromatase which triggers the conversion of testosterone to estrogen. Testosterone has a role to play in fat distribution, and if T levels drop, we are more likely to develop fat around the abdominal area.

Bone density

Both androgens and estrogens have a part to play in the preservation and maintenance of bone health. Throughout the process of bone remodeling, our bodies use three types of cells to rebuild our bone tissue as it breaks down. Androgen hormones and testosterone included, activate receptors in these cells contributing to bone remodeling. Osteoporosis is a condition where bone remodeling doesn’t keep up with bone deterioration which leads to brittle bones, and low testosterone levels can contribute to the development of this illness.

Circulation

Although the effects of testosterone on the cardiovascular system are a bit of a controversy at the moment, there are proven positive effects of testosterone on this system. Testosterone causes vasodilation, a process that causes the relaxing of the muscular walls in our blood vessels lowering blood pressure and allowing the heart to pump blood with more ease. There are other benefits, too, like its impact on the production of red blood cells in the bone marrow. It potentially also has positive effects on cholesterol and clot-busting. Still, we’ve also seen reports of negative effects causing issues with cardiovascular health, so we’re still far off from the results being conclusive, and this is the case only with high testosterone levels.

Skin health

Testosterone plays a big role in skin health. There are testosterone creams and pills on the market designed to improve skin health by impacting skin tightness, elasticity, thickness, and its ability to produce muscles. Still, high testosterone levels can also cause skin issues like acne, overly greasy skin, and so on. Like with all hormones, finding the right balance is crucial.

Hair Growth

Testosterone has many forms, but the one that is relevant to us here (but also for skin health) is DHT (Dihidrotestosteron), a form of testosterone that impacts skin and hair significantly. DHT usually has a positive effect on body hair and beard and is the source of that “high testosterone equals more hairy men” thing. It’s also responsible for the myth that people with high testosterone grow bald, and although there is a connection here, it’s not as direct as all that. DHT can cause baldness BUT only in men who have a genetic sensitivity to DHT. Researchers figured this out when they noticed that some men with high DHT don’t grow bald while others do.

The central nervous system

Our body can manipulate and control testosterone through hormones and chemicals. In turn, testosterone can have an impact on our mood, contributing to aggression and dominance. Its role is to regulate self-esteem and give us that competitive spark. Low testosterone, in turn, can cause a lack of motivation, confidence issues, sadness, lack of energy, and so on. Overly elevated T levels are said to cause aggressive behavior accompanied by a lack of control, but this hasn’t been confirmed yet, and even if it were to be true, we already know that elevated testosterone levels are bad for our bodies.

The reproductive system

Testosterone is responsible for the development of male genitals within the first seven weeks of conception. During puberty, it helps the penis and the testicles grow, which helps our body produce more testosterone and also produce fresh sperm each day.

For women, testosterone is responsible for the repair of their reproductive system, which is very important, considering it naturally gets damaged every month. On top of that, testosterone is converted into oestradiol in the female body, which is the primary sex hormone for females.

Sexual Desire

Not being sexually active may lower your testosterone, and low testosterone leads to erectile dysfunction. Being sexually aroused raises your testosterone levels and contributes to the overall well-being of a man.

What are normal testosterone levels?

There are two factors we need to consider when assessing optimal testosterone levels: gender and
age.

Men

Keep in mind that men can experience testosterone levels that are higher than they should be. That’s why we have the upper values on the chart above. High testosterone can lead to irritability, a stop in sperm production, shrunken testicles, worsened sleep apnea, and skin problems.

Excess testosterone over prolonged periods can cause even worse health issues related to cholesterol, cardiovascular issues, and infertility. In most cases, high testosterone levels are a consequence of either the use of synthetic steroids or a tumor of the testicles or the adrenal gland.

The exception would be men who have naturally raised testosterone levels as a genetic predisposition, due to which they should be subverted to regular testing and should seek ways to reduce the risks this condition brings to the table.

Women

As you might have noticed the ng/dL is always under a specific value for women. This is because if this value goes over the proposed number, doctors may consider that the female patient is producing excess testosterone. Overly high levels of testosterone in females can cause frontal balding, deepening of the voice, acne breakouts, and muscle growth and warrant a visit to your doctor.

Conclusion

Testosterone is a very important hormone to keep track of in both men and women. Keeping its levels in the normal ranges ensures that our bodies can perform at optimal capability. The consequences of either elevated or deficient testosterone levels cause some annoying issues, especially with mood regulation. In extreme cases, they can cause very negative effects, which are difficult to get rid of and may seriously threaten one’s health.
It also has a major impact on male development in the teenage years, quite literally transforming boys into men with the development of core male traits.

Hormones, in general, make a big difference in our lives, so regardless if you are male or female, you should keep track of your hormonal balance to ensure you remain healthy and avoid adverse symptoms.
