1. What does healthy semen look like?
1. Sperm and semen are different.
Dr. Nicholas Martha, the founder of the Michigan IVF Center and an infertility expert, said that people often mistakenly exchange the terms "sperm" and "semen" at will. In fact, semen is a mixed body fluid produced by male penis ejaculation, and semen contains sperm.
2. Once ejaculating, the semen heat is 5~ 10 calories.
Dr Paul Sinn, a urologist at the Shedi Grove Fertility Research Center in Washington, D.C., said that semen is mainly composed of water, and also contains fructose-like sugar, protein prostaglandin produced by prostate and various enzymes. The heat of semen in one ejaculation is less than 10 calories.
Although the number of sperm is amazing, it is not easy to conceive successfully.
Dr. Sinn said that the amount of semen in an ejaculation is about 1.5~5 ml, and the number of sperm contained can reach150,000. However, there are many obstacles and traps in the process of sperm filling eggs. For example, semen waste caused by women walking; The pH value of semen is weakly alkaline, while female private parts are usually slightly acidic. Sperm must also find the egg through the correct fallopian tube and be in good shape.
4. "Preejaculation semen" usually does not contain sperm.
Dr. Sinn said that "pre-shooting semen" is not strictly semen, but a viscous secretion produced by the prostate, which mainly plays a lubricating role.
5. Sperm can survive for 5 days in women.
Dr. Hong said that sperm likes a warm and humid environment, and the survival time of sperm after entering a woman's body is quite long, up to 5 days. In vitro, sperm can only survive for a few minutes.
6. Some habits can damage sperm.
Frequent smoking, taking hot baths many times a week, putting a laptop on your lap and being overweight are the main culprits of sperm damage.
7. It takes about 3 months to produce and eject sperm.
It takes about 64 days for a man to produce sperm, and then it takes about 24 to 28 days for the sperm to run and finally ejaculate.
8. The taste of semen is hard to change.
People will change the taste or smell of semen. Dr. Sinn said that studies have found that smoking will worsen the smell of semen, which is largely related to various toxins in cigarettes.
9. The concentration of semen changes every day.
The amount of drinking water will directly affect the concentration of male semen. Drinking less water will thicken semen, while drinking more water will dilute semen. However, Dr. Sinn said that some semen will be in a gelatinous stage before it comes into contact with prostaglandin. Once the two are combined, semen will be smoother because of "liquefaction".
10. Men can't freeze their semen.
Professional frozen semen uses liquid nitrogen, and the freezing temperature reaches MINUS 190 degrees Celsius. So DIY freezing semen at home will only kill sperm.
1 1. Semen allergy is extremely rare, but it is possible.
Once a patient with semen allergy comes into contact with semen, the skin at the contact site will have itching, redness and other symptoms. But the incidence of female is less than 1%, which can be treated.
12. The amount of sperm produced by a man in his life is frightening.
95% of healthy men will produce about 2 trillion sperm in their lifetime, of which 700 billion are ejaculated. ▲ (Life Times special correspondent Chen Zonglun)
2. Precautions for male pregnancy
First, physical examination
After the couple have a "baby plan", the first thing to do is to have a physical examination to determine whether the health before pregnancy is in good condition. Good health is the foundation of a healthy baby.
Male physical examination is not only to check semen, but also to check sperm quantity and sperm vitality. It needs to know more about its health.
Second, a reasonable diet.
As the saying goes, "Food is the most important thing for the people", and eating is an extremely important thing for us. It is not only for us to fill our stomachs and have an addiction, but its most important function is to meet the normal physiological needs of the body and prolong our normal life.
But no matter what kind of food, it is impossible to have all the nutrients needed by the human body. Therefore, the diet during pregnancy must be comprehensive and balanced to ensure the intake of various nutrients.
Sperm has the most obvious demand for zinc, selenium and protein, so male friends can eat more foods rich in zinc, selenium and protein. In addition, fresh fruits and vegetables are rich in vitamins and can be eaten more.
Third, proper exercise.
Although some people now have objections to "life lies in exercise" and criticize this statement as incomplete, no one dares to refute the benefits of proper exercise.
Men who exercise regularly and moderately have stronger semen indexes than men who don't like sports. Insisting on exercise can enhance physical fitness, improve self-immunity, reduce the probability of suffering from andrology diseases, and promote metabolism, which is conducive to the production of healthy sperm.
Therefore, it is recommended that pregnant men exercise three times a week for half an hour to an hour, and swimming and jogging are good choices. Exercise is expensive, but it should not be excessive. Marathon and cycling for a long time will make sperm quality worse.
Fourth, go to bed early and get up early
Staying up late has become a habit of modern urban life. You don't have to study or soak your feet before you go to bed, but you must brush your Weibo and circle of friends. Before I knew it, it was early in the morning, so I had to put down my cell phone and sleep.
The normal work of various functions of the body needs a healthy and orderly environment, while men who stay up late for a long time and lack sleep have poor physical condition and mental outlook, and their fertility level is also low.
Therefore, pregnant men should rest on time, and it is recommended to go to bed before 1 1 at night and keep enough sleep every day. Men who often suffer from insomnia or poor sleep quality should pay attention to regulating their bodies and go to the hospital for treatment when necessary.
