What is the healthy standard of male semen?

　　Xia Bing has been married for two years. Not only has the young man grown strong, but he also discharged a large amount of semen every time he had sex in the past. However, the amount of semen recently has been significantly reduced than before, even as little as a few drops. This makes him worried that it will affect his future sexual life and fertility.
　　
　　A normal man has semen in his body from the first nocturnal emission to the end of his life. Dream The more frequent sexual intercourse, masturbation, and sexual intercourse, the greater the semen consumption will naturally be. However, the seminal vesicles, prostate, and bulbourethral glands are the same as other glands in the body. As long as they function normally, they will secrete continuously, so semen will not be exhausted. Some young men masturbate frequently, once for several days or several times a day, which will significantly reduce the amount of semen.
　　
　　The reason is very simple. Although the human body produces sperm , the ability of semen is very strong, generally it can be replenished in 1 to 2 days after ejaculation, but ejaculation If the frequency is too high, supply will still exceed demand. This condition causes too little semen, of course not disease , don’t worry, once the interval between ejaculation is extended, it will be cured.
　　
　　However, if the amount of semen discharged every time is too small, it is pathological. exist male Among infertility cases, infertility caused by too little semen (less than 1 ml) accounts for about 2% of the total cases. Low semen may be caused by abnormal testicular function, endocrine disorders, seminal vesicles, prostate disease or urethral stricture. This type of low semen is easy to identify. You only need to abstain from sex or stop masturbating for 5 to 7 days before ejaculating again. If the semen is more than before, there is usually no problem. Otherwise, it is pathological oligospermia and you should seek medical treatment in time.
　　
　　So, is excessive semen good? If the amount of semen discharged at one time exceeds 8 ml, it is called excessive semen. This is also a pathological condition, mostly caused by inflammation of the seminal vesicles and hypersecretion of pituitary gonadotropin. The so-called excess semen is essentially excessive secretion or leakage of seminal plasma, while the total number of sperm has not changed. The density of sperm in the semen has decreased, thereby reducing the chance of pregnancy. Excessive secretion of seminal plasma can also interfere with sperm activity and function due to the influence of pathological factors such as inflammation. In addition, excessive semen will cause semen containing a large amount of sperm to be lost from the vagina, which will also reduce the chance of pregnancy. Therefore, more semen is not always better.
　　
　　The trouble of thinness and thickness
　　
　　Jinsong once heard a buddy complain privately that his semen was as thin as water, and he still has no children. Jinsong himself has another worry: After graduating from graduate school, he has been married for 5 years and has normal sex 2 to 3 times a week. Neither husband and wife take contraceptive measures, but his wife has not become pregnant so far. After examination, his wife's reproductive organs, menstruation, and ovulation functions were normal. The number and shape of Jinsong's sperm were also normal. However, it took more than an hour for the ejaculated semen to change from jelly-like to thin. This jelly-like semen affected his wife's pregnancy.
　　
　　Semen originally exists in a liquid state in the reproductive tract. When semen is ejected from the mouth of the penis, it will immediately turn into a milky white or yellowish translucent jelly under the action of a protein-like substance secreted by the seminal vesicles. This is the semen character that people usually see. At this time, the sperm is coagulated in the semen and cannot swim freely. After 5 to 30 minutes, with the participation of a hydrolase secreted by the prostate, the semen liquefies and automatically changes from jelly to thin water.
　　
　　This change process of sperm has very important physiological significance: it is in a liquid state at the beginning to facilitate the ejaculation of semen; then it forms a gel shape, which helps the semen stay in the vagina for a long time and allows the sperm to fully rest and capacitate; once liquefied, the sperm has enough energy to swim quickly to find eggs for "blind date".
　　
　　If diseases such as inflammation of the prostate or seminal vesicles occur, semen may not liquefy for a long time or may not liquefy completely due to lack of secretion or destruction of hydrolase. The phenomenon that the ejaculated semen liquefies after half an hour or even an hour is a pathological phenomenon, which is medically called non-liquefaction of semen.
　　
　　Although semen that is as thin as water will affect pregnancy, semen that is too viscous will prevent sperm from swimming normally, which can also cause infertility. Therefore, patients with abnormal semen liquefaction should be actively treated.
