Face-slimming injections are a cosmetic procedure that has become very common and popular. Many female friends get face-slimming injections for the sake of beauty, but in fact, they are very harmful to their bodies. Especially if you are still in the pregnancy preparation period, you should not get face-slimming injections, otherwise your pregnancy preparation will be greatly affected. You should also not go to the sauna frequently. 4. Sauna and frequent hot baths: The testicles need an environment that is 1℃-1.5℃ lower than the normal body temperature of 37℃ to produce sperm. Data show that if a person with normal sperm density soaks in warm water at 43-44 degrees Celsius for 20 minutes for three consecutive days, the sperm density can be reduced to below 10 million/ml, and this situation can last for three weeks. Therefore, taking hot baths too frequently or for too long will reduce sperm count. 5. Smoking. Smoking is not only the enemy of eugenics, but also one of the causes of infertility. Research has found that smoking in women can interfere with and destroy normal ovarian function, causing menstrual irregularities, premature menopause and infertility. Even if a smoking woman becomes pregnant, it is more likely to cause miscarriage, premature birth and stillbirth, and the weight of the baby born is much lighter than that of a non-smoker. Infertility patients with low rates are not suitable. 6. Malnutrition and picky eating. The production of sperm requires raw materials, so spermatogenesis is closely related to nutritional levels. This does not necessarily mean eating soft-shelled turtles or eels. However, it is still essential to eat more lean meat, eggs, fish and vegetables to ensure the necessary supply of protein, vitamins and trace elements. People who are picky eaters are often prone to certain nutritional deficiencies. 7. Drinking. Modern medicine suggests that excessive drinking can endanger the function of the reproductive system, cause endocrine disorders, and change the chromosome structure and number of reproductive cells. Drinking alcohol causes blood vessels to dilate, speeding up the absorption of toxins in the body. 8. The impact of work pressure, mental factors and personality traits on the reproductive function of men and women cannot be ignored. This slows down the body's ability to clear toxins, thus reducing sperm quality. The normal sperm count in smokers decreases by 10%, and the sperm deformity rate increases. The longer the smoking time, the more deformed sperm there are and the lower the sperm motility. At the same time, smoking can also cause diseases such as arteriosclerosis. More than 90% of smokers have poor blood circulation in the penis and slower penile erection. Excessive or long-term drinking can accelerate the decomposition of testosterone in the body, leading to lower testosterone levels in men's blood, decreased libido, sperm deformity, and impotence. Therefore, for the healthy birth of the next generation, we should try our best to quit smoking and drinking. |
