Why is the color of ejaculation a little yellow?

We all know that men's semen is not only a physiological product, but also the key to conceiving a baby. Men's semen is generally milky white, and although it has a little smell, it is still acceptable. In clinical practice, doctors often judge diseases based on the color of men's semen, and the accuracy is quite good. So, why is the semen ejaculated by men a little yellow? Is it because of a sexually transmitted disease or something like that?

1. Yellow semen is considered abnormal

Yellow semen is considered abnormal. Abnormal semen includes: milky white or yellow-green semen, indicating inflammation in the reproductive tract, most likely a purulent infection of the prostate and seminal vesicles. Red semen indicates that the semen contains red blood cells, commonly known as "hematospermia". Hematospermia is mostly caused by seminal vesiculitis or prostatitis. This type of hematospermia caused by inflammation is mostly light red. If small blood vessels rupture due to vascular malformations, hematospermia will be bright red and contain blood clots.

2. Yellow semen may be normal

Is yellow sperm a sign of disease? In fact, semen is composed of sperm and seminal plasma. Sperm accounts for only a very small part, and more than 90% is seminal plasma. Seminal plasma is secreted by accessory glands such as the prostate, seminal vesicles, bulbourethral glands, and paraurethral glands. The main component is water, as well as fat, protein particles, pigment particles, lecithin bodies, enzymes, fructose and other components. The color of semen is determined by the components that make up the semen. The semen of a normal person is grayish white or slightly khaki. If the abstinence period is long, the color will be yellower due to changes in physical and chemical properties. This is all normal.

Normal semen color

Normal semen color is off-white or slightly yellowish, and after liquefaction, it becomes translucent milky white. If ejaculation has not occurred for a long time, it may appear slightly light yellow. If semen appears yellow-green, it indicates that there may be inflammation in the male reproductive tract or accessory glands (such as prostatitis and seminal vesiculitis). If semen is red (including bright red, light red, dark red or soy sauce color), it is highly suspected that the semen contains blood (hematospermia). After examination, those who contain a large number of red blood cells can be diagnosed with hematospermia, which is common in patients with accessory glands and posterior urethritis, and occasionally in patients with tuberculosis or tumors.
