56. Excessive Testosterone Leads to Strange Behavior in Men: Researchers announced on the 26th that they had discovered through research that excessive testosterone can kill brain cells. This discovery can explain why the abuse of steroids can lead to behavioral changes, such as becoming aggressive and having suicidal tendencies. Laboratory trials on brain cells showed that an appropriate amount of male testosterone is beneficial, but excessive testosterone causes brain cells to self-destruct, a process similar to the damage Alzheimer's disease inflicts on brain cells. According to Reuters, Barbara Ehrlich, the leader of the study from Yale University, said, "Too little or too much testosterone is harmful, but an appropriate amount of testosterone is very beneficial." Testosterone plays a crucial role in the growth, development, and classification of cells. Both men and women secrete testosterone, just that men secrete 20 times more testosterone than women. Testosterone is also an important substance that promotes male sexual development and maintains sexual characteristics. However, testosterone is abused in sports. Athletes often abuse testosterone or take steroids to gain an unfair competitive advantage; steroids can be converted into testosterone within the human body. Barbara said, "Our experiments show that when the level of steroids in the human body is too high, the level of testosterone will also be too high, and excessive testosterone can kill nerve cells. We know that when people lose brain cells, they lose some functions." Barbara's scientific team also conducted the same experiment using female hormones (estrogen). She said, "We were surprised by the results of the experiment, but it seems that estrogen has a protective effect on the nervous system. If there is estrogen present in the human body, fewer brain cells die." The researchers published their findings in the journal Biochemistry. Barbara and her colleagues wrote in the article that their findings suggest that people should think twice before supplementing with testosterone, despite its ability to make muscles grow strong and aid recovery after training. They wrote, "The effects of testosterone on the nervous system can have long-term impacts on brain function." Barbara humorously wrote in a statement, "Next time on the highway, if a muscular man driving a sports car speeds past your car recklessly, don't get angry. You'd better take a deep breath because it's not his fault." Testosterone can cause abnormal behavior, such as being more aggressive. The cell death process is called apoptosis, or programmed cell death. Barbara and her colleagues wrote in the article, "Apoptosis is crucial for the brain, which needs to remove some brain cells. However, if this process happens too frequently, people will lose too many brain cells, and diseases will follow." Excessive testosterone increases the frequency of brain cell death. The pathogenesis of Alzheimer's disease is similar to the damage caused by excessive testosterone on brain cells. Alzheimer's disease is the most common cause of dementia in the United States, affecting approximately 4.5 million Americans. Huntington's disease also follows a similar mechanism. The researchers wrote in the article, "Our experimental results indicate that the reaction of brain cells to excessive testosterone can be compared to these two diseases."
57. Which Diseases Are "Written" on a Man's Face? The condition of internal organs in the human body reflects on the face. You, who are busy, might as well observe your own face regularly, perhaps revealing secrets about your health. Sudden increase in forehead wrinkles indicates that the liver is overburdened. You should eat less animal fat, such as pork, and instead consume more light foods like pig liver, spinach, tofu, and fish. An unattractive complexion signifies issues with the body. It is difficult to have a flawless complexion; everyone's face has some minor imperfections that are hard to notice. Dark circles under the eyes and a dull complexion in the morning indicate that the kidneys are overburdened. You should reduce salt and sugar intake, avoid adding sugar where possible, undergo food therapy with dishes like duck meat cooked with chestnuts, braised Chinese cabbage, or drink red and white radish soup with meat. Additionally, eating pig kidneys in soup is also effective. Red nose represents the condition of the heart. A red or purple tip of the nose may indicate high blood pressure or excessive consumption of salt and alcohol. Swollen upper lip could be due to gastric spasm. Eat more warm stomach foods like potatoes, sweet potatoes, chestnuts, yams, lotus roots, etc. If the skin is too rough, try soups made from bamboo shoots, sea cucumbers, and lean meat. Overly pale skin might be due to insufficient blood and qi. Soak jujubes and peanuts in warm water, then cook them gently, add honey and boil until sticky. Regularly consuming such foods will make your complexion rosy. Rosy cheeks indicate hypertension. Reduce smoking or quit smoking altogether, monitor blood pressure regularly. Red ears represent kidney conditions. Red or purple earlobes suggest poor circulation. Drink less alcohol, eat less refined food and sugar, exercise more to promote circulation.
58. Why Do Males Develop Breasts When Using Contraceptives? College students use contraceptives to concoct "hair-growing shampoo," experts say this practice is baseless, males abusing contraceptives cause hormone secretion disorder, possibly developing breasts. The age group suffering from hair loss continues to decrease, even including white-collar workers and middle school students, sociologists believe this "social disease" induced by mental stress and excessive pressure can easily trigger psychological disorders. Sixty percent of those with hair loss do not seek treatment at regular hospitals, doctors remind that hair loss might be a warning sign of certain internal medical conditions, this "top priority" requires serious attention. Some college students use contraceptives to treat hair loss. Can contraceptives cure hair loss? Some students in Dalian universities have started trying with a "let's see" attitude. Recently, Xiao Cheng, a third-year student at a university in Dalian, told reporters that one roommate with hair loss problems was very concerned about how hair thinning affected his appearance. Since he recently secured several interview opportunities, he actively sought out folk remedies for hair regrowth. Last week, this roommate took a box of medicine named "Compound Norethisterone Tablets" to borrow grinding tools from Xiao Cheng, stating that the medicine must be ground into powder and mixed with shampoo for use. "I didn't know much about medicine, but upon carefully reading the packaging instructions, I realized it was a contraceptive drug," Xiao Cheng was surprised when asking his classmate whether this action carried any risks, receiving the reply that it was learned online, "Even if it doesn't work, it probably won't cause any harm." Based on the URL provided by Xiao Cheng, the reporter found this "anti-hair loss tip": "Contraceptive drugs mainly contain large amounts of progesterone and female hormones, the usage method involves grinding it into powder and mixing it with shampoo or conditioner, but oil-based hair oils should be avoided because the medicine must come into contact with the scalp to take effect. If used three to five times, significant results are said to appear." This remedy ended with a somewhat irresponsible note: "As for its credibility and potential for causing mutations, it is second-hand information passed down from doctors. Its reliability cannot be fully confirmed." One netizen commented on this post as "strange folk remedies left behind by quacks." Males abusing contraceptives risk developing breasts. After searching online, the reporter found that multiple women's websites or beauty sites claim that contraceptives "stop hair loss and promote hair growth," some netizens share their experiences live in forums: "It's true. I've only been using it for a week, and my hair has already grown significantly." A "reproductive science doctor" evaluates the effectiveness of contraceptives in preventing hair loss as "beneficial without any harm." A gynecologist in Dalian told reporters that using contraceptives to treat hair loss lacks scientific basis. "Since contraceptives contain female hormones that may stimulate hair follicles, promoting hair metabolism, short-term use may accelerate hair metabolism due to stimulation of the follicles," the doctor said. But it must be reminded that this short-term effect caused by hormones has underestimated negative side effects. Because hair growth is mainly controlled by hormone secretion in the body, the relationship between scalp absorption and hair growth isn't very tight. Long-term use of hormone products can easily destroy scalp follicles, leading to hair loss in users. This doctor said that the misleading information about "beautifying with contraceptives" online may originate from some women experiencing increased hair volume after taking oral contraceptives. However, clinical observations show that after stopping contraceptives, due to reduced hormone levels, most people experience hair loss. This is one of the main reasons for the increase in female hair loss patients. "Male hair loss patients especially should absolutely avoid abusing contraceptive drugs," the doctor said, a hormone imbalance-induced condition known as "gynecomastia" has an incidence rate of around 4%. Due to excessive secretion of female hormones in males, breast tissue grows.
59. Why Are Male Testicles Outside the Body? Testicles are the most important sexual organs in males; they produce sperm and secrete male hormones, fundamentally making men what they are. However, why did God place such an important organ outside the body, where it is easily damaged, rather than inside the body where it would be relatively safer? For testicles to maintain normal physiological functions, the optimal temperature required is around 35 degrees Celsius, whereas the body's internal temperature of 37 degrees Celsius is detrimental to their function. Some cryptorchid patients (due to embryonic developmental disorders causing the testicles to fail to descend normally into the scrotum) have poorly functioning testicles due to prolonged exposure to high temperatures, resulting in poor or no sexual function. Since testicles are highly sensitive to temperature, the scrotum takes on the task of regulating testicle temperature. When exposed to cold and the testicle temperature drops too low, the scrotal skin contracts to prevent heat loss; when the testicles become too hot, the scrotal skin relaxes to dissipate heat. Men should easily understand these changes in their scrotum. However, it must be clear that the scrotum's temperature regulation function has limits. When temperature changes exceed its regulatory range, the physiological functions of the testicles will inevitably be harmed. Therefore, care should be taken with your testicles as it affects their heat dissipation. Similarly, sitting for long periods on loose sofas also affects lower body heat dissipation. In daily life, wearing loose pants, maintaining ventilation and dryness in the lower body ensures a comfortable working environment for the testicles, allowing them to function optimally.
60. A Must-Eat Food for Men Who Experience Nocturnal Emissions: Lotus seeds can treat nocturnal emissions, as extensively documented in ancient medical texts. The "Medical Forest Anthology" states: "Lotus seeds, eaten raw with the core removed and the skin intact, are most beneficial. They can alleviate irritability, quench thirst, constrict essence, harmonize blood, stop nocturnal emissions, and regulate cold and heat." The "Compendium of Materia Medica" records: "Lotus seeds connect the heart and kidneys, strengthen the intestines and stomach, consolidate essence, strengthen sinews and bones, replenish deficiencies, benefit hearing and vision, eliminate cold and dampness, and stop diarrhea and chronic dysentery, treating both red and white discharges and various blood diseases in women." Traditional Chinese medicine divides nocturnal emissions into two types: emissions during dreams involving intercourse with the opposite sex are called dream emissions, while emissions without dreams are called slipping emissions. Regardless of whether they are dream emissions or slipping emissions, the method of consumption is the same. Remove the core from the lotus seeds, chew four or five seeds with the skin intact each time, once daily, and results will naturally appear over time. Additionally, lotus seeds have the benefits of tonifying the spleen, benefiting the lungs, nourishing the heart, strengthening the kidneys, and consolidating the intestines, making them an excellent therapeutic diet for palpitations, insomnia, and physical weakness.
61. Assessing His Sexual Ability Through Ejaculation: After extensive efforts, American health experts have published a list of health gold standards. Before your partner boasts about being in great shape, it might be worthwhile showing him this list first. To clarify: a man who fully meets all 11 tests and qualifies as "truly healthy" is extremely rare! If he meets 7 out of the 11 criteria, he can be considered a model of good health, and if ever human cloning becomes necessary, he could undoubtedly serve as the best provider of human cells. 1. He has the highest level of HDL (high-density lipoprotein): Dr. Eckel points out: "HDL has the function of cleaning arteries, and if it reaches or exceeds 90 mg/dl, severe vascular blockages are rarely likely to occur." 2. He has two close friends: These friends should not be his current colleagues, neighbors, fitness coaches, or anyone else who consistently appears in his life. Psychologist Dr. Sherrod believes: If a man over 35 meets this standard, it indicates he has healthy social connections and will live longer. 3. He answers "Yes" to the following two questions: "Do you look forward to going to work every morning?" "Do you look forward to coming home every afternoon?" After 30 years of practical research, Dr. Glassburn discovered that men who answer "Yes" to both questions have a very low risk of dying from heart-related diseases. 4. PSA (prostate-specific antigen) value below 2.5 ng/ml: Prostate cancer expert Dr. Hilton points out that this indicator suggests a lower risk of prostate cancer. 5. Ejaculatory capacity: After a very satisfying session of bed activity, his ejaculation volume should reach 5 ml. Dr. Hilton believes this is the most direct indication of prostate health. 6. He can walk 3 kilometers in 28 minutes: Maintaining a brisk and powerful pace for a considerable length of time while walking quickly is truly a great way to measure physical health. According to Swedish researchers, a healthy 40-year-old man should be able to walk 3 kilometers in 30 minutes. 7. Balanced muscle strength: For example, the ratio of bicep to tricep strength should be 1:1, meaning if he can pull a resistance band with 25 kg of force 10 times, he should also be able to push a weight of 25 kg 10 times, neither more nor less. 8. Symmetrical head proportions: Clinically, a facial width of 60% of the length is optimal. Men with such standard heads are not only handsome but also have excellent immunity against respiratory, jaw, and dental diseases. 9. Quick hill climbing: Start by walking on a flat treadmill at a speed of 5 km/h; then gradually increase the incline, raising it by 5 cm every 3 minutes. Most men aged 30-40 can last 9 minutes, and reaching 12 minutes is quite remarkable. 10. Successfully threading a needle on the first try. 11. Perfect symmetry on both sides: Take out a soft tape measure. Measure the circumference of his wrists, ears, and nostrils. If these areas are perfectly symmetrical or differ by only 1 mm, he is a natural athlete. The more balanced the body, the better the self-control during intense exercise.
62. Common Daily Items That May Affect Sexual Ability: Frequently consuming fruits and vegetables with large pesticide residues on their skins can lead to higher levels of estrogen in the male reproductive system, gradually causing toxic reactions in the testes and other sex glands. American scientists have found that some chemicals can actually shrink the penises of some men and the clitorises of women! Moreover, these chemicals exist in our daily lives! Changes in the shape of genital bones, shrinking of male penises and female clitorises: American scientist Christian Sonne was astonished to find that a chemical pesticide called OHCs significantly affects
