Read this interesting article that offers some relevant scientific facts about testosterone and its impact on human body. Many people associate testosterone with muscles, aggression, baldness or eve drug abuse! In short, testosterone seems to be pure male energy. But did you know that testosterone is a hormone that both male and female bodies make?
What Is Testosterone?
Testosterone is widely known as a sex hormone. It is said that males have more than 5 times higher testosterone levels than females. Testicles, ovaries and adrenal glands create testosterone in male and female bodies.
According to the Wikipedia source, testosterone is a steroid hormone that is produced both naturally and artificially. In medicine, testosterone is used for treating various types of cancers while in sports it is occasionally misused for athletic ability enhancement.
Why is Testosterone Important for Human Body?
Many studies have shown that optimal testosterone levels are crucial for our health system and prevention of various diseases. When testosterone levels are satisfactory, we feel energetic, confident, happy, while our heart, muscles, and bones are protected. With testosterone level deficiency, we might experience fatigue, stress, depression, low libido, and even risks of Alzheimer’s disease, osteoporosis and obesity.Read more here
Low Testosterone & Health Impact
Testosterone levels decrease with age; a study done by the World Health Organization has proven that an average, 70-years-old man has only 10-20 % testosterone in comparison to a man of 25. Apart from age as a testosterone decline factor, there are other factors that have impact on the decrease of testosterone in our bodies, namely:
- Stress- hormone cortisol prevails over testosterone and causes its decrease in stress situations. A research in 2010 has found that cortisol potentially influences testosterone levels. It might even slow down the production of testosterone, as shown by this study.
- Zinc deficiency- zinc is essential for healthy testosterone levels in the body. Even a slight deficiency can already take care of this mineral for testosterone depletion, according to several scientific studies. Studies also demonstrate that increasing zinc through diet or supplements can reverse the negative effects of a deficit.
- Saturated fats- deficiency of saturated fats can affect testosterone levels. We are taught to believe that too much on saturated fats (deriving from meat, eggs etc.) are bad for us. However, they do contribute to the increase of testosterone in our bodies. A research (1997) found that an increased intake of animal fats increased the testosterone levels in athletes, in comparison to men with a low fat diet.
Concrete Testosterone Therapy Benefits
In cases of low testosterone, a testosterone therapy can be used for boosting energy and even sex drive; additionally, the testosterone therapy could potentially contribute to:
- improved mood, concentration and sleep
- improved bone density/strength
- increased strength and athletic performance
- improved insulin sensitivity
- improved erectile function
- improved motivation and overall wellbeing
- fat reduction
- muscle increase
Testosterone & Sexual Drive
It is perhaps interesting to mention that testosterone increases our sex appeal. Women are attracted to men with higher testosterone levels. Even the desire for morning sex has been linked to higher levels of testosterone as that is the time of our testosterone peak. A researcher from the University of St Andrews has analyzed the co-relation between sex associated hormones and facial features.
For example, the mentioned study subjects have noted that the photo’s of men with seemingly wider jaw lines or stronger eyebrows give the impression that they possess additional testosterone.
Interestingly enough, the subjects believed that testosterone is associated with being successful. At the same time, they linked it to being unreliable or extroverted.People with higher level of such hormones were generally rated as attractive.
