1, and the judgment criteria are as follows
(1) Semen volume: normal ≥2ml. Too much when it exceeds 7ml, not only reduces the sperm density, but also easily flows out from female private parts, resulting in a decrease in the total number of sperm, which is common in seminal vesiculitis; Less than 2ml means too little semen, but usually less than 1ml. At this time, the contact area between semen and female reproductive tract is small, or because of its viscosity, it is not conducive to sperm entering the woman's cervix, leading to infertility, which is common in severe accessory gland inflammation, low testosterone level, ejaculatory duct obstruction, retrograde ejaculation and so on.
(2) Color: usually grayish white or light yellow. Milky white or yellow-green suggests inflammation of reproductive tract or accessory gonad; Microscopically, pink, red and red blood cells are bloody semen, which is common in inflammation of accessory gonads and posterior urethra, and occasionally seen in tuberculosis or tumors.
(3) pH value: The normal pH value of semen is 72 ~ 78. Less than 72 is seen in ejaculatory duct obstruction or urine pollution; More than 78 cases are found in seminal vesicle inflammation or old specimens.
(4) Liquefaction time: After normal semen is injected, it becomes gelatinous under the action of seminal vesicle coagulase and liquid 15 ~ 30 minutes under the action of prostatic liquefaction enzyme, which is semen liquefaction. It is abnormal that semen is not liquefied after 30 minutes of ejaculation.
(5) Stickiness: The glass rod comes into contact with the liquefied semen and gently lifts it to form semen filaments, the length of which is generally less than 2cm.
2. Does semen taste normal?
The taste of semen is the most significant.
Semen, like saliva, gastrointestinal fluid and blood, belongs to human body fluids, but only the smell of semen is the most significant. Semen is not as pure as other body fluids, but a mixed liquid. In addition to sperm, seminal plasma in semen is composed of prostatic fluid, epididymal fluid, seminal vesicle fluid and various secretions of urethra and vas deferens.
Normal semen smells like chestnut flowers.
The smell of normal semen is emitted by a chemical called refined ammonia after oxidation, much like the smell of chestnut flowers. Spermine is one of many important components in prostatic secretion. The oxidation of refined ammonia inevitably involves seminal vesicle fluid, and the prostatic fluid obtained by rectal massage generally has no smell of natural ejaculated semen.
Beware of prostate diseases when semen is tasteless.
It can be seen that the smell of normal ejaculated semen comes from the prostate, but it is emitted with the participation of seminal vesicle fluid. The special smell of insufficient semen often indicates the damage of prostate function, and the semen of many prostate patients often cannot smell this smell.
As for the physiological significance of the special smell of semen, it is speculated that it may be related to desire and sexual behavior. In lower animals, the information of sexual activity and sexual selection mainly depends on the sense of smell; Many mammals emit a special smell to attract the opposite sex during estrus.
Food can also change the taste of semen.
The composition of semen is not fixed and will change with time. Sperm injected during the day may contain more sperm and semen, while at night it contains more prostatic fluid. Foods that affect the taste of semen include asparagus, chicken, dairy products, red meat, cauliflower, broccoli, greasy food, spices, coffee, chocolate and so on, which will make the taste of semen strange. It smells bad, so it should be moderate. Try to eat less garlic and onions, which will thicken semen.
The smell of semen cannot be removed.
As for the smell of semen, there is no need to eliminate it, and it can't be eliminated. It is human nature to love cleanliness, but now it is obviously a stale concept to regard sexual behavior and semen as "dirty" things. In addition, warn people who love cleaning that excessive use of "foreign objects" such as deodorant or perfume will make you lose the sexual charm of natural body odor.
