What color of semen is normal? Men must be alert to four kinds of heterochromatic semen

How is the color of semen normal? The health of semen directly affects the quality and health of the pregnant fetus, and by looking at the color of men's semen, we can understand certain health conditions. How can semen color be normal? What color is sperm? What color is sperm? Under normal circumstances, if it is a male who regularly ejaculates, the semen should be milky white; If there is no ejaculation for a long time, the color of semen will be light yellow; If the color of semen is red, there may be blood in semen; If the color of semen is very yellow and thick, there may be pus cells.

1. Normal semen is milky white or light yellow.

2. The light yellow color may be due to no ejaculation for a long time, so the color changes slightly and is thicker, which is normal. If the male genital tract is inflamed, the semen will also be yellow, and a large number of pus balls can be seen under the microscope, which may be caused by the suppurative infection of the prostate and seminal vesicle.

3. If the semen is red or light red, sometimes it will appear brownish red or maroon, and a large number of red blood cells can be seen under the microscope, which is commonly called "blood essence". Most of these symptoms are caused by seminal vesiculitis or prostatitis. In addition to bleeding symptoms, some people may have pain. How is the color of semen normal? Why is the blood red and urine yellow? Such as color change, is it normal or a symptom of disease?

Let's take a look at what's going on.

1. Semen Semen is usually white and transparent, and may also be clear. Men who have sex or masturbate more often will have clearer semen color. The pink or reddish semen indicates inflammation or bleeding of the prostate. The yellow semen may be mixed with urine or jaundice. In most cases, it is OK, but if you feel unwell, you should also see a doctor.

2. Mucus and mucus cover the outer membrane surface of many important organs of the human body, including the lungs, sinuses and gastrointestinal tract, to keep these membrane surfaces from drying. The mucus of healthy people is usually clear. However, when a cold or virus is infected, the immune system will send a large number of white blood cells to the sinuses. The white blood cells contain green enzymes, and the mucus will have a similar color. If the amount of mucus is large, it will appear yellow or green. When it is dry in winter, the nasal capillaries will break and bleed, which will make the mucus red. If the amount of bleeding is large, protective measures or medical treatment should be taken in time.

3. The color of urine comes from the urine pigment after hemoglobin decomposition. Normal urine color ranges from nearly clear to medium yellow. Darker or lighter urine may be a sign of dehydration or excessive drinking. Pink or red urine may be benign, such as eating beet at dinner, or it may be disease symptoms, such as bleeding caused by kidney infection, urinary tract infection, even kidney tumor, mercury poisoning. In addition to dehydration, orange urine may also be caused by liver or bile duct problems. When the urine appears strange color, after removing the dietary factors, it is necessary to see a doctor in time.

4. Blood is red because of a large number of red blood cells. Red blood cells are responsible for sending oxygen to human tissues. But why is the vein blue? This is related to light reflection. The light reflected by blood vessels needs to pass through the skin before reaching the human eye. Only the wavelength of blue light has this ability, so blood vessels look blue.

What is the normal appearance of semen

1. Semen volume: normal ≥ 2ml. If it is more than 7ml, it is too much, not only the sperm density is reduced, but also it is easy to flow out of the vagina, so that the total number of sperm is reduced, which is common in seminal vesiculitis; Less than 2ml is too little semen, but usually less than 1ml is too little. At this time, the contact area between the semen and the female genital tract is small, or because the viscosity is not conducive to the sperm entering the female cervix, resulting in infertility, which is common in severe paragonadal inflammation, low testosterone level, ejaculatory duct obstruction, retrograde ejaculation, etc.

2. Color: normally gray white or slightly yellow. Milky white or yellow-green color indicates inflammation of the genital tract or accessory gonads; Pink, red, and red blood cells seen under the microscope are bloody semen, which is common in inflammation of accessory gonads and posterior urethra, and occasionally in tuberculosis or tumor.

3. PH: The normal pH of semen is 72-78. Less than 72 can be seen in ejaculatory duct obstruction or urine contamination; More than 78 can be seen in seminal vesicle inflammation or obsolete specimens.

4. Liquefaction time: after normal semen is ejaculated, it becomes gelatinous under the action of seminal vesicle coagulase, and becomes liquid under the action of prostate liquefaction enzyme after 15-30 minutes, which is semen liquefaction. It is abnormal that semen does not liquefy 30 minutes after ejaculation.

5. Viscosity: contact the glass rod with the liquefied semen and gently lift it to form semen silk, which is normally less than 2 cm in length.

6. Sperm count: generally expressed by the number of sperm per milliliter of semen. Normal count ≥ 20 × 106/ml。 Below this value, there are too few sperm, which can be seen in spermatogenic dysfunction caused by various reasons, and can lead to low fertility or infertility due to the reduced chance of sperm entering the uterine cavity and fallopian tube. If sperm count is greater than 250 × 106/ml refers to excessive sperm, which can also lead to infertility due to the influence of its activity.

7. Sperm morphology: sperm with normal morphology ≥ 50%, otherwise it may cause infertility.

8. Activity: ≥ 50% of sperm move forward rapidly in a straight line.

9. Survival rate: usually refers to the examination within 1 hour after ejaculation, and the live sperm ≥ 50%. The common causes of decreased sperm motility and survival rate include inflammation of accessory gonads, varicocele, ciliary stagnation syndrome caused by chronic respiratory infection, anti-sperm antibody in semen or improper storage of samples.

10. White blood cells: white blood cells in normal semen
