The core manifestation of men's hormonal health with testosterone as the core is not at all "exuberant body hair, rough voice, and explosive muscle mass" as reported on the Internet, but that the entire person's state is in a stable and "effortless" state, and there is rarely any unexplained loss of control.
I met an older brother at the gym two years ago. He is a 37-year-old engineering engineer who often runs projects. He does not deliberately follow the bodybuilding route, but his body fat is stable between 17% and 19% all year round. He does not have to deliberately eat boiled vegetables every time and will not suddenly gain more than ten pounds. He stays up for two consecutive nights to catch up on projects, and can recover after a day's slowdown. He rarely feels too tired to move at all times, and rarely gets angry with his wife and children over trivial matters at home. He had been working for almost a month in a row to rush for delivery. During that time, not only did his hair fall out violently, but he also felt inexplicably irritable. He would start arguing with people when he encountered traffic jams on the road. When he went to the hospital to check his total testosterone, he just found the lower limit of the normal reference value, and his free testosterone almost fell out of the standard line. After adjusting his work and rest and exercising regularly for more than three months, he returned to the midline of the reference value after another check, and his condition also returned.
Speaking of which, there is quite a controversy about this matter on the Internet. One group thinks that high androgen means dense body hair and fast beard growth. The other group thinks that as long as the physiological functions are normal, there is no problem. In fact, both of these opinions are a bit biased. The amount of body hair is mostly determined by genetics and androgen receptor sensitivity. I have a friend whose family is born with light body hair. He only shaves his beard every two or three days. When I checked for hormones, everything was within the appropriate range. He usually exercises and is in good condition, so there is no problem at all. ; On the contrary, I met a young man before who had obvious beard and chest hair. He always felt that he was tired easily and lacked energy. When he checked his testosterone, it was a little lower than the normal value. This is because the receptor sensitivity is high. On the outside, he looks "androgen-rich", but in fact, it is not enough on the inside.
To put it bluntly, hormones are like the invisible fuel of the body. You don't need to look at the "powerful" label on the outer shell. The truth is to listen to whether there are any abnormal noises in the engine and whether it runs smoothly. Many people around the age of 40 always think that "it is normal to gain weight and get tired easily in middle age". In fact, this is not the case. I have met an uncle who is almost 50. He does not smoke and rarely drinks alcohol. He plays badminton three times a week. Last year, his testosterone was still at the normal median value for the age-appropriate people. His belly is not protruding, and he does not suffer from backache and back pain when climbing stairs. He rarely loses his temper with his family, and even sleeps very steadily. He can fall asleep in ten minutes on the pillow and rarely wakes up in the middle.
By the way, if you want to check your hormones, don’t just focus on the total testosterone value. Free testosterone is the part that can really be used by the body. Some people’s total testosterone seems to be stuck at the passing line, but the free testosterone ratio is low, and they will still have problems such as tiredness, poor mood, and slow metabolism. Don’t think that everything will be fine if you pass the passing line.
