What is abnormal semen color?

Semen is composed of sperm and seminal fluid, with sperm accounting for only a small portion. Over 90% of semen consists of seminal plasma, which is secreted by accessory glands such as the prostate, seminal vesicles, and bulbourethral glands. Its main components include water, fats, protein particles, and lecithin bodies. The color of semen is determined by these constituent elements. What constitutes abnormal semen color?

What Is Abnormal Semen Color?

1. Semen appearing milky white, yellowish-green, or brown pus-like: Yellowing of semen is primarily caused by infections in the reproductive tract. If semen remains yellow despite regular sexual activity, it may indicate inflammation within the reproductive system, likely due to conditions such as prostatitis or seminal vesiculitis. If not treated promptly, this can affect semen quality and potentially lead to infertility, possibly resulting in abnormal sperm morphology or sperm agglutination. These conditions may cause the semen to turn yellow; therefore, timely medical evaluation and treatment are recommended.

2. Pink or red semen: This may indicate hematospermia (blood in semen), commonly seen in patients with urethritis, genitourinary tuberculosis, tumors, or stones. During intercourse, rapid congestion and mechanical impact may cause minor blood vessel ruptures and bleeding in certain tissues. There's usually no need for excessive concern about such temporary bleeding—suspending sexual activity for one or two weeks typically allows full recovery.

Through this introduction to male semen color, men should now have a better understanding of the importance of monitoring their semen. Regular observation of semen color and consistency can help detect potential health issues early. Any abnormalities should prompt immediate medical examination. To avoid affecting future health and fertility, proper diagnosis and treatment are essential.
