What are the early warning indicators of male hormone health risks?

At present, the core early warning indicator commonly used in clinical practice is serum total testosterone level. Adult men aged 18-50 years old have fasting blood tests. If the total testosterone is less than 12nmol/L, it enters the health risk warning range. If the total testosterone is less than 8nmol/L, it is basically a high risk of testosterone deficiency and requires timely intervention.

However, this value is not a definite gold standard. There have been different voices in the academic community: many andrology experts believe that 98% of total testosterone is bound to albumin and sex hormone binding globulin, and cannot directly exert physiological effects. Looking at total testosterone alone is prone to misjudgment, and must be combined with truly active free testosterone indicators to be accurate. Usually, free testosterone lower than 225 pmol/L is a more accurate warning line. Now many men's departments in domestic tertiary hospitals have included free testosterone in routine screening items.

The 32-year-old Internet operator I treated last week is a typical example. He stayed up late at night for three months in a row to work on projects. Recently, he always felt lazy. He just wanted to slump after get off work. He was obviously not interested in married life. He also always lost his temper with his family for no reason. The total testosterone in a fasting test was 11. 7nmol/L, just stepped on the regular warning line, and the free testosterone was only 203pmol/L, which is a bit lower than the standard value. Even if this kind of testosterone deficiency has not reached the pathological level, you must quickly adjust your work and rest and control your weight, otherwise you will have to rely on drug intervention if it continues.

Not all people who step outside the numerical value need to be nervous. I met a 57-year-old retired teacher before. The total testosterone in the physical examination was only 10.8nmol/L, but he played badminton for one hour every day, had a regular schedule, no fatigue, and normal emotional and physiological needs. This is not considered high risk, and there is no need for medication at all. Regular follow-up is enough. To put it bluntly, testosterone is like the "life battery" of the male body. Everyone's basic power consumption is different. You cannot just look at the total capacity marked, but you must also judge it based on the actual usage status.

Many people now have a misunderstanding. They think that low testosterone is a problem that only middle-aged and elderly people encounter. In fact, there are many young men in their twenties who step on the warning line. Last month, a 26-year-old boy came for a routine physical examination. His body fat rate was 34%. He never leaves his hand with milk tea every day. After sitting for more than ten hours in class, the total testosterone found was only 9.2nmol/L, which was lower than the 57-year-old teacher just now. He didn't feel it clearly yet. It would take more effort to adjust it when hair loss, erectile function decline, and continued depression appear later.

If in the past six months you have experienced inexplicable tiredness, loss of libido, sudden fat gain in the belly, and a general lack of energy, don’t force yourself to do it. Just take a fasting blood test to check for testosterone. Early detection and early adjustment are better than anything else.
