It is almost a consensus in China and abroad that the traditional Chinese medicine attaches great importance to the prevention of diseases, as Sun Simiao once said in the “Thousand Gold Essentials” that “the upper medicine cures the disease that is not yet sick, the middle medicine cures the disease that wants to be sick, and the lower medicine cures the disease that is already sick. In the West, Thomas Adams also said that prevention is far better than cure, because it saves people from getting sick. The drugs and surgeries cost money and take time, and people pay a lot of attention to these obvious things, but many people ignore the lifestyle adjustments and other aspects of male fertility protection, not knowing that these non-costly things are more important, as the Zuo Zhuan says, “Only the weapon and the name can not be false”. Case 1: Male infertility patient, 32 years old, needed IVF after bilateral tubectomy for his spouse’s ectopic pregnancy, but the patient had been smoking heavily, two boxes per day, and I advised him to avoid smoking in the clinic, but he thought it didn’t matter, as long as he had our advanced IVF technology, he could easily get it done, and as a result, the patient started to spend half a year on his first IVF, which ended in The patient began to spend six months on her first IVF, which ended in failure. After the failure, the patient paid attention to the problem, refrained from smoking and tried again six months later to get his spouse pregnant successfully. Case 2: male infertility patient, 30 years old, the patient is fat, and almost no sauna, the patient showed severe oligospermia, drug therapy has been poor, to the clinic, the author focused and the patient talked about lifestyle changes, the patient recognized these problems, physical exercise, weight loss, and also not sauna, the results of a cycle of drug therapy, the effect was immediate. Second, case study: Lifestyle adjustments, although not costly, are very important for the treatment and prevention of male infertility. These lifestyle adjustments are mainly: avoid smoking, because foreign data studies show that smoking can increase DNA damage, increase aneuploidy sperm, may lead to testicular atrophy, can make the semen volume, concentration, vitality and morphology and other indicators of abnormalities, some foreign fertility centers in order to maintain their high success rate even require patients to quit smoking for at least 3 months before entering the IVF cycle; should not drink a lot of alcohol, but The radiation is inversely proportional to the cube of the distance, the distance increases by one, the radiation attenuation is 1/8; stay away from all kinds of harmful chemicals; don’t take sauna, don’t wear tight underwear for a long time, taking sauna or wearing tight underwear for a long time will make the local temperature rise and inhibit sperm production; eat more fish, traditional Chinese medicine believes that fishermen have more sons, maybe fish swim bladder The main ingredient of a proprietary Chinese medicine called fish bladder and kidney pill is fish bladder; lose weight, human adipose tissue contains aromatase, which converts testosterone into estradiol, lowering serum testosterone levels and raising estradiol, which adversely affects the normal spermatogenesis process; exercise, the latest research shows that exercise helps improve testosterone levels and sperm quality in the body The latest research shows that exercise can help improve testosterone levels and sperm quality in the body; avoid high fever, some information shows that if a fever exceeds 39 degrees, sensitive men may be inhibited from sperm production for more than half a year, small-scale foreign studies show that high fever can affect sperm DNA integrity, some foreign IVF centers recommend that it is best to carry out IVF after 2 months of high fever, etc.; maintain a good state of mind, a good state of mind is more important for infertility treatment, especially for women. Especially for women, a bad state of mind can affect the reproductive endocrine system, thus affecting fertility. The success rate of IVF is mainly related to the age of women, with a success rate of 30-40% for women aged 30-40, 5-10% for women aged 40-45, and close to 0 for women aged 45 and above (because the success rate of IVF is not as high as the success rate of IVF). However, the success rate is close to 0 (because female fertility is related to age, women reach the peak of fertility at the age of 24, at the age of 35, their fertility is only half of that at the age of 24, at the age of 38, only a quarter, and above the age of 40, less than 5%), but details, such as avoiding smoking and other precautions are also very important, the details sometimes determine success or failure, so the patient’s success in IVF after avoiding smoking. It is possible that the details played an important role. Case 2: This patient had severe oligospermia, but he started to pay attention to the tangible medication and neglected the intangible lifestyle adjustment, which resulted in the poor efficacy of medication.
