Normal testosterone level in men
Normal indicators of testosterone rate in male blood are crucial for his health, mood and general activity. It affects all the systems of the body and even the ability to have children.
In this article, we will tell you about the normal rate of this androgen in male blood and its main indicators which vary depending on the age.
The norms of bioavailable, total, free male hormones vary greatly depending on age, but also on the method of determination and units of measurement adopted in a particular laboratory. They usually calculate the norm of testosterone in nmol/l, ng/dl or ng/ml.
Total testosterone rate indicates a quantitative indicator of all forms of the androgen in the blood serum. Total testosterone rate in men depends on individual and age characteristics: from 18 to 69 years – 6-38 nmol/l; from 70 years – 4-20 nmol/l. The normal level of free hormone in a man should fit into the following indicators: from 18 to 69 years – 5.5-42 nmol/l; older than 70 years – 4.9–7.3 nmol/l.
There is a calculated indicator that determines the ratio of free and total testosterone-the free testosterone index. The free testosterone index allows you to get accurate information about what influence testosterone has for cells, also it is used to assess the bioavailability of testosterone and the overall androgenic status.
The rate of the hormone in men is preconditioned by age: the main androgen begins to be produced in the prenatal period, the most significant increase in its level occurs in adolescence, the peak of production falls at 18 years. After 35 years, the secretion of the androgen begins to decrease. After 40 years, the rate of this androgen in men decreases by 1-1.5% per year. After 55-60 years, due to androgen deficiency, it becomes more difficult for men to lose weight or gain muscle mass. Approximately determine what level of testosterone your blood should contain, we recommend you to use the table of norms of the male hormone for different ages.
Testosterone fluctuations also depend on the time of day. The highest level is recorded in the morning, in the evening it gradually decreases and reaches a minimum. The concentration of the hormone can vary depending on various factors affecting the body: genetic characteristics, the presence of chronic diseases, psycho emotional state, physical activity, the nature of nutrition, bad habits such as drinking alcohol , taking drugs, smoking. Test for testosterone in usually taken on an empty stomach, at least 8 hours after the last meal, better in the morning.
Deviations in the secretion of the main male sex hormone can lead to serious disorders of the body. If you have any signs of deviations we advise you to visit your physician or endocrinologist.
