Age Progression of Testosterone and Self-check

What is Testosterone?

Testosterone is one of the steroid hormones known as male hormones. This hormone is related to the reproductive function in men, muscle development, maintenance of bone density, as well as mood and energy levels.

Age-related Fluctuations in Testosterone The testosterone level in men reaches its peak around the early twenties and gradually decreases thereafter. It is said that this decline becomes significant from the late thirties to the forties. And after the fifties, the level continues to decrease even further.

Age-specific Trends in Testosterone

Youth: Testosterone levels increase sharply from the early to mid-teens. This leads to the onset of secondary sexual characteristics in males during puberty.

20s: For many men, testosterone levels peak in the early twenties. The average testosterone value is about 300-1,000 ng/dL (nanograms per deciliter), but men during this period often show values closer to the upper limit of this range.

30s: From the late twenties to the thirties, testosterone levels are said to decrease by about 1% each year.

40s: The decline from the late thirties to the forties becomes even more pronounced, especially in the mid-forties and beyond.

50s and beyond: At this age, the decline in testosterone continues, and as they progress into their 60s and 70s, many men reach values close to the lower limit of testosterone.

Why Does Testosterone Decrease?

The decline in testosterone is mainly attributed to changes in the function of the testes, pituitary gland, and hypothalamus with age. Moreover, chronic stress, excessive alcohol intake, specific diseases, and the use of certain medications are known to affect testosterone levels due to lifestyle and health conditions.

Signs of Decreased Testosterone

The following are some symptoms that might indicate a decrease in testosterone:

• Decreased sexual desire
• Reduction in stamina and muscle mass
• Fatigue
• Feelings of impatience and irritability
• Symptoms of depression
• Increase in body fat

Self-check Method

It's challenging to determine a decrease in testosterone levels based solely on symptoms. If you have suspicions, it's recommended to consult a doctor. However, it's essential to pay attention to changes in your body and symptoms in daily life and consider whether they might be related to a decrease in testosterone.

Conclusion

Testosterone levels naturally decrease with age. This decline can potentially cause various physical and mental changes. If you notice any changes, it's recommended to consult with a doctor first. Recognizing early and taking appropriate measures can help maintain a healthy everyday life.
