1, man's semen
Semen examination is an important examination item to evaluate male fertility and reflect testicular spermatogenesis and accessory gonad function. In life, men can check their semen by the following simple methods.
Sperm volume: 2-6 ml.
The amount of semen refers to the amount discharged by each ejaculation. Under normal circumstances, the amount of semen in one ejaculation is 2-6 ml. The amount of semen is related to the length of abstinence. The longer abstinence, the more semen, and vice versa. If the amount of semen is too small for a long time, it may lead to difficulty in conception. Too much semen will reduce sperm density. If you use condoms in the same room, you can look at the amount of semen inside after each room. If it suddenly becomes more or less, you need to pay attention.
Color: milky white or gray.
The semen just injected is gelatinous, grayish white or grayish yellow. The semen that does not ejaculate for a long time is dark in color, and the semen of the elderly is mostly dark yellow. If the semen is brown or bloody, it may be related to diseases such as urinary system inflammation and reproductive tract injury, such as prostatitis and seminal vesicle prostate cancer. If the semen is too transparent and thin, it means that the sperm density is low.
Smell: faint fishy smell.
Normal semen has a special faint smell, which is produced by the oxidation of polyamines in prostatic fluid. The longer abstinence, the bigger the smell. If there is obvious odor, consider whether there is infection.
Change: Jelly becomes thinner.
At room temperature, semen will solidify into colloid immediately after it is ejected from the body, and then enter the liquefaction process and gradually become thinner. This process is mostly completed in 15 minutes. If it is more than 30 minutes, the semen will not liquefy or liquefy completely, which is more common in patients with prostate and seminal vesicle diseases.
After mastering this knowledge and making sexual suggestions, the couple will observe the semen by the way to see if it meets the above criteria. If you are worried about problems, it is best to abstain from sex for 3-5 days and go to the hospital for routine semen examination. The clinical semen analysis report lists a large number of data, some of which are worthy of attention.
Sperm density: 654.38+0.5 million per milliliter is normal.
Sperm density refers to the number of sperm per unit volume. Sperm density is less than150 thousand /ml, which belongs to oligozoospermia, and the chances of sperm entering uterine cavity and fallopian tube will be reduced, which will lead to the decline of pregnancy ability; If it exceeds 200 million /ml, it belongs to polyspermia, which will also affect the fertility of sperm.
Sperm vitality: Sperm moving straight ahead ≥32%.
Sperm motility is generally divided into four levels. Grade 0 refers to inactive sperm; 1 grade refers to the sperm moving in situ; Grade 2 is the slow swimming of sperm forward curve; Grade 3 is sperm swimming straight ahead; Grade 4 is a fast and straight sperm. To successfully conceive, it is generally required that the proportion of third-grade sperm plus fourth-grade sperm should be greater than 32%.
Sperm survival rate and deformity rate: above 58% and below 92% respectively.
Under normal circumstances, the sperm survival rate is above 58% and the abnormality rate is below 92%, which is an ideal index.
Semen PH value: stable at about 7. 1.
The PH value of most semen is stable at about 7. 1. Too high or too low can be inflammation.
Finally, I would like to remind you that the semen report cannot be "conclusive", and specific problems need to be handled by doctors.
2, semen has no nutrition.
"One drop of essence and ten drops of blood" is complete nonsense.
In fact, you can eat semen, but you won't get pregnant because your eggs don't come from your stomach.
Eating sperm will not greatly supplement the body, because semen is a mixture of sperm produced by testis and seminal plasma secreted by prostate. The main component of seminal plasma is water, accounting for more than 90%. Other ingredients include fat and protein granules, pigment granules, phospholipid corpuscles in prostatic fluid, amines, free amino acids, various enzymes, lactic acid, fructose and inorganic salts. This is similar to the situation in plasma.
Seminal plasma is the carrier of sperm, which can neutralize, buffer and protect sperm, so that sperm can survive in acidic environment of female private parts.
The seminal plasma is rich in fructose and sorbitol, which provides inexhaustible nutrition for sperm movement. Although there are many kinds of nutrients, the content is very small, even less than 0. 1%.
Many scientists have proved that "one drop of sperm, ten drops of blood" is wrong, because although semen is nutritious, its content is very small, and we can eat half a bowl of rice with a few drops of semen. You are not afraid to eat if you have this hobby. Anyway, it has become a very common thing.
