The causes of seminal fluid non-liquefaction generally, in the formation of semen, sperm and epididymal fluid account for about 10%, the seminal fluid produced by the seminal vesicle gland accounts for about 60%, and the prostatic fluid produced by the prostate gland accounts for about 30%, which together form the seminal fluid. The function of this substance is to prevent other harmful substances from damaging and destroying the sperm in the semen, and to protect the sperm. The spermatozoa are protected from other substances in the semen by the seminal vesicle gland, but after the semen is ejaculated, the semen must be liquefied before the sperm can leave the semen and enter the female reproductive tract. This is the normal situation, from the normal situation, we can know that if the prostate gland has some lesions, affecting the secretion and production of protein hydrolase in the semen, it will make the liquefaction of semen problems, the liquefaction time is delayed, liquefaction viscosity increases, so that the sperm can not be released from the semen, it will affect fertilization, resulting in male infertility, this is the semen is not liquefied This is the cause of semen opacity and his condition. Diagnostic criteria for semen non-liquefaction Normal semen is liquefied when it is ejaculated, but it immediately solidifies into jelly or clot, and then liquefies into a watery liquid after about 10-20 minutes, this process is called the liquefaction of semen, which is a normal physiological phenomenon. If the semen is still in jelly form after 30 minutes, it is a pathological condition and is called non-liquefaction of semen. The semen starts to liquefy to facilitate ejaculation, then becomes jelly-like to allow the semen to stay in the female vagina and not flow out easily, and later liquefies again to allow the sperm in the semen to move fully so that it can swim along the female reproductive tract towards the fallopian tubes to facilitate sperm-egg union and fertilization. Treatment of semen non-liquefaction 1, supplemental zinc and magnesium trace elements can improve sperm non-liquefaction Adult men need 15 mg of zinc per day, but since the amount absorbed is usually less than the amount supplemented, it is best to supplement with greater than 15 mg of zinc per day. Magnesium can improve sperm vitality, so it is important to supplement zinc with magnesium to achieve a “two-pronged” approach. Generally speaking, zinc is divided into two ways: one is oral zinc preparations, but the human body ingested too much zinc, it is easy to cause zinc poisoning, so should be taken under the guidance of a doctor; the other is to eat some zinc-containing foods, such as seafood, sesame, peanuts, apples, bananas, etc.. Magnesium-rich foods are beans, purple cabbage, oats, etc. 2, a yam, goat kidney porridge with wolfberry, fried leek with walnuts, duck with cordyceps, etc. can also improve the symptoms of sperm non-liquefaction. 2, pay attention to the living room decoration: formaldehyde has a strong damaging effect on the genetic material in the cells, it is a volatile organic substances, all kinds of decorative materials contain to varying degrees. So in the selection of decorative panels, be sure to choose qualified, low formaldehyde content of the material. In addition, benzene (often contained in paints, coatings, adhesives) is also an important source of pollution. Be careful not to buy paints or adhesives that contain benzene. After the house renovation, it is best to open the doors and windows for 1 summer, and then move in to live as appropriate. Granite contains a kind of radioactive substance – radon. Radon is one of the rare gas elements and is the product of metamorphosis of radioactive elements such as radium and thorium. Radon, which is metamorphosed from radium, is a colorless gas with a half-life of 3823 days. Long-term exposure to radon is harmful to health and can also kill sperm and cause infertility. 3, drug pollution: frequent use of sedative drugs, anti-tumor drugs, chemical drugs, furan drugs and hormone drugs can cause sperm growth disorder, sperm chromosome damage and breakage.
