What color is normal for sperm?

The change of sperm color is an immediate and important manifestation of the health status of men. Many people must be very worried about the change of their sperm color. Then let the mother Baidu Encyclopedia tell you what to do if the sperm color changes?

1. What is normal sperm color?

According to the normal semen standards set by the World Health Organization, whether semen is normal can be analyzed from the following aspects:

Under normal circumstances, the color of semen is gray or slightly yellowish. If it is milky white or light green, it indicates that there is inflammation in the reproductive system or parasitic hormones.

The color of semen is determined by the composition of semen. The semen of ordinary people is gray or slightly beige. If you abstain from sex for a long time, the color will become yellower due to changes in physical and chemical properties. This is all normal.

2. What diseases may be caused by abnormal sperm color?

Under normal circumstances, semen should be transparent egg white-like milky white. The semen of people who have not ejaculated for a long time may be light yellow or light yellow, and more viscous.

When a man has an inflammation in his reproductive system, his semen may be light yellow. The reason why male sperm is bright red is that during ejaculation, the seminal vesicle produces obvious contraction and contraction, which causes the permeability of the capillaries in the seminal vesicle wall to change, causing blood cells in the blood vessels to penetrate into the semen. When the frequency of sexual intercourse is low, the secretion in the seminal vesicle continues to increase, which increases the pressure. When a man ejaculates, the pressure of the seminal vesicle decreases, causing the capillaries to rupture and bleed. The specificity of enzyme substances that dissolve tissue fibroblasts in the semen of men with allergic constitutions increases, causing the capillaries on the seminal vesicle wall to be damaged and cause bleeding.

3. Factors that affect sperm color change

Semen is composed of male sperm and seminal plasma. Male sperm only accounts for a small part of the total volume, and more than 90% is seminal plasma. Seminal plasma is metabolized by the male prostate, seminal vesicles, bulbourethral glands, urethral glands and other attached sex hormones. The main component is water, and there are also various components such as human fat, protein particles, melanin particles, glucose, etc.

Normal people's semen is gray, milky white or light yellow. If you abstain from sex for a long time, the color will be yellower due to changes in physical and chemical properties. This is all normal. If the semen is light green, it means there is inflammation in the reproductive system, which may be a purulent infection of the prostate and seminal vesicles.

If the semen is bright red or light red, it means that there are blood cells in the semen, which is generally called "ejaculatory bleeding". Ejaculatory bleeding is mostly caused by seminal vesiculitis or prostatitis, and ejaculatory bleeding is mostly dark red. If small blood vessels rupture due to vascular malformations, ejaculatory bleeding will be red and there will be blood clots.
