Why is the sperm yellow?

Yellow sperm is becoming more and more common, but since there are no other symptoms, many people don't pay much attention to it. If the disease is allowed to develop, it will cause serious consequences, and even eventually lead to symptoms of sexual dysfunction, which will make the treatment more serious. After all, standard sperm is milky white, and it will only appear yellow after inflammation of the reproductive organs. Standard sperm 1. Semen volume: 2~6ml per ejaculation, but it is affected by the frequency and number of ejaculations. Less than 1ml/time is called reduced semen volume, and more than 6ml/time is called excessive semen volume. These are all abnormal conditions.

2. Semen color: Normal semen is transparent grayish white. If the abstinence period is long, it may be light yellow. If there is inflammation in the reproductive tract, the semen may be yellow or even contain blood.

3. Sperm density: Sperm density refers to the number of sperms contained in each milliliter of semen. Normally, the number of sperms per milliliter of semen is more than 20 million. If it is less than 20 million/ml, it is oligospermia, which will affect fertility.

4. Semen liquefaction time: Semen is in a gel state when it is just discharged from the body. It will become a liquid state after 5 to 30 minutes. This process is called liquefaction. The liquefaction of semen requires the participation of a series of proteolytic enzymes. Semen that is viscous and not liquefied. It is common in patients with prostate or seminal vesicle diseases. Semen is weakly alkaline, with a pH value between 7.2 and 7.8. If the pH is <7, it is acidic, and if the pH is >8, it is alkaline, which will restrict sperm function.

5. Sperm 1-hour survival rate: The percentage of active sperm within 1 hour after ejaculation should be no less than 60%.

The semen is quantitatively diluted with diluent (sodium bicarbonate in the diluent decomposes mucus to destroy the viscosity of semen, and formaldehyde fixes sperm), and then dripped into the blood cell counting pool for counting. The normal sperm count is (60-150)×109/L, and the lower limit of pregnancy is 20×109/L. Clinically, it can also be reported according to the total number of sperm in one ejaculation. The normal number is 400-600 million, and less than 100 million is abnormal.

Sperm with flagella can swim. After the release of swimming sperm, it can be active for about 1 hour at 22-25℃. Once the sperm reaches the egg cell, the flagellar band structure will fall off by itself, and then the sperm nucleus will directly contact the egg. As for whether sperm without flagella can move autonomously, there are different opinions. The number of sperm produced by the antheridia or male gametophyte of various plants varies greatly: one antheridia of Isoetes can produce 4 sperm, 128-256 in Selaginella, thousands in Psoralea corylifolia (thick-sac fern), and hundreds in Psoralea corylifolia (thin-sac fern); the male gametophyte of seed plants generally produces only two sperm. The general trend of evolution is that swimming sperm with flagella gradually simplifies into sperm cells without flagella. The movement mode of sperm also changes from swimming with flagella to transporting sperm with pollen tubes. For example, the fertilization of lower vascular plants must be carried out under the condition of a certain amount of water. This reflects the aquatic habits of algae to a certain extent. Although the sperm of Su Tie and Ginkgo biloba retain the flagella of algae and lower vascular plants, the sperm has transitioned to transport with the help of pollen tubes. In the gymnosperm pine and angiosperms, the movement of sperm is freed from the restriction of water conditions and is completely transported by pollen tubes.
