A complete collection of men’s health facts

90% of the "men's health warnings" you search online are anxiety created by marketing accounts. The health details that really need your attention are all "cold facts" that no one is embarrassed to mention and you are embarrassed to ask. Most of them have nothing to do with "kidney deficiency", so don't take supplements randomly.

Last week, a 22-year-old college student came to the outpatient clinic. His face turned red while he was holding his registration card. He said that his balls have always been cold to the touch recently. After searching, he said it was "kidney cold". He had already bought three boxes of kidney-tonifying pills to eat, and almost bought an Internet-famous infrared physiotherapy lamp for baking, fearing that it would affect future fertility. I couldn’t laugh or cry after hearing this. The optimal temperature for sperm survival is originally 2-3°C lower than the core temperature of the human body, about 34-35°C. Coolness is normal. If it feels hot to the touch one day, you should be alert to whether varicocele or epididymitis is coming to your door. Of course, that doesn’t mean that what is said on the Internet is all wrong. There is indeed a syndrome differentiation of “kidney cold” in the context of traditional Chinese medicine, but it is accompanied by a whole set of symptoms such as soreness and weakness in the waist and knees, premature ejaculation, fatigue, and excessive nocturia. It is purely to scare yourself by talking about the temperature alone. Men who are preparing for pregnancy should deliberately avoid bathing in hot springs and wearing tight jeans for fear that high temperatures will kill sperms. It’s better for you to take the initiative to bake.

Speaking of this, I think of another question that everyone is ashamed to ask. Many men will subconsciously shake after going to the toilet, then turn around and search online to see if they have kidney deficiency. In fact, it is really unnecessary. This is a sudden drop in abdominal pressure when you urinate, and the muscle contraction is driven by vagus nerve excitement. It is a normal physiological reaction that happens to both men and women, but girls’ movements are not obvious. By the way, don’t label yourself as having prostatitis as soon as you see bifurcated urination. If you have a morning erection just after urinating and you hold it for two hours before going to the toilet, bifurcation will occur due to pressure on the urethra and the sphincter has not been relaxed temporarily. Only when bifurcation occurs every time you urinate, accompanied by painful urination and perineal swelling, do you need to go to a regular hospital to check the prostatic fluid. Oh yes, some people always think that their frequent urination is caused by prostate problems. You should first calculate how much water you drink in a day. If you drink enough 2L a day, it is completely normal to urinate 6-8 times during the day and 0-1 times at night. If you drink half a bottle of mineral water a day and run to the toilet every ten minutes, it is not too late to check.

When it comes to kidney deficiency, we have to mention the hair loss problem that men are most anxious about. I met a patient who works in development a while ago and has an annual salary of more than 300,000 yuan. In order to treat M-shaped hair loss on the top of his head, he bought more than 4,000 yuan of Gushen ointment and black sesame pills. In fact, 90% of male androgenic alopecia is caused by dihydrotestosterone (DHT) attacking hair follicles. It has nothing to do with kidney deficiency. Even if you eat a ton of black sesame seeds, you can't stop DHT from causing harm. Of course, there are different opinions here. Some Chinese medicine practitioners believe that kidney deficiency is one of the causes of androgenetic alopecia. However, the current mainstream clinical treatment options are still oral anti-DHT drugs and topical minoxidil. Kidney replenishing is at best an auxiliary conditioning, and it must not be used as a core therapy. If you really want to save your hair, it is better to stay up less late at night than anything else.

Don’t think that hair loss and prostate problems are only exclusive to men. There is another piece of trivia that 99% of people don’t know: men can also get breast hyperplasia and even breast cancer. I met a 45-year-old truck driver during my surgical rotation before. He had a hard lump on his left chest that he had been carrying for half a year. He always felt that "women get breast disease, and men can't have anything wrong with it." When he came for a check-up, he was already in the middle stage of breast cancer. Because male breast tissue is thin, cancer cells are more likely to metastasize, and the prognosis is worse than that of female patients. In fact, although the incidence of breast cancer in men is only about 1% of that in women, the risk is always there. If you feel a painless lump in your chest or inexplicable nipple discharge, don’t be embarrassed and go to a breast examination as soon as possible. The delay is really not worth the gain.

There are also "testicle-stimulating supplements" that have become very popular in the fitness circle recently. I also advise everyone not to take them blindly. Last month, a 26-year-old fitness blogger came for a pre-pregnancy check-up. His sperm motility was less than 20%, which is lower than the normal value for a 60-year-old man. After asking for a long time, he said that he had been taking the Internet-famous "natural testosterone stimulating hormone" for half a year in order to gain muscle. After taking it for a test, he found that illegal synthetic androgens were added to it. Long-term consumption will directly inhibit his own testosterone secretion, and in severe cases, it will cause testicular atrophy. It took him almost a year to slowly return to normal. If you really want to stimulate testicles, do aerobics for half an hour three times a week, stay up late and drink less alcohol. It is more effective than any supplement and has no side effects.

Oh yes, let me finally talk about the sexual issue that everyone is most concerned about. Don’t be led astray by the short videos on the Internet. You think the longer it goes on, the worse it will be. The clinical diagnosis of premature ejaculation is that under the premise of regular sexual intercourse, ejaculation occurs less than 1 minute after penetration. The normal duration of sexual intercourse is 2-8 minutes. If ejaculation cannot occur after more than 15 minutes, it is called delayed ejaculation, which is also a disease and must be treated. Many people take delaying medicine blindly in order to last for a long time and hold on without ejaculation. In the long run, it will cause repeated congestion of the prostate, which may induce prostatitis in mild cases or directly cause ejaculation disorders in severe cases. It is really unnecessary.

In fact, to put it bluntly, many misunderstandings about men's health are caused by either being embarrassed to ask questions because of shame, blindly judging the symptoms online, or being frightened by marketing accounts selling supplements. If you really feel uncomfortable, go to a regular hospital and get a consultation. It costs more than ten yuan, which is much better than searching on Baidu for a long time and scaring yourself.
