Normal semen is grayish white or slightly yellowish, with a special fishy odor. The odor is emitted by a chemical substance called arginine after oxidation, much like the odor of chestnut flowers. Arginine is one of the many important components contained in prostate secretion, and the oxidation of arginine must pass the sexual excitation of ejaculation, when the prostate secretes prostatic fluid and seminal vesicle fluid, the joint action can produce odor.
Diet can also cause changes in odor
The composition of semen is not fixed and changes over time. The ejaculated semen during the day may contain more sperm and semen, while at night it contains more prostatic fluid. The foods that affect the taste of semen include asparagus, chicken, dairy products, red meat, cauliflower, broccoli, greasy foods, spices, coffee, and chocolate, which can give semen a strange taste. It doesn't smell good, so it should be in moderation. Try to eat less garlic and onions as they can make semen thicker.
Changes in semen odor
Abnormal semen includes: the semen is milky white or slightly chartreuse, indicating inflammation in the genital tract, which is likely to be a purulent infection of the prostate and seminal vesicles. The red color of semen indicates the presence of red blood cells, commonly referred to as "blood semen". Blood semen is mostly caused by seminal vesiculitis or prostatitis. This type of blood semen caused by inflammation is mostly light red in color. If a small blood vessel ruptures due to vascular malformation, the blood semen appears bright red and blood clots can be seen.
Be alert to male diseases
The odor of normal ejaculation semen comes from the prostate gland, but is only emitted with the participation of seminal vesicle fluid. The lack of this special odor in semen often indicates damage to prostate function, and many prostate patients' semen often cannot smell this odor. Therefore, for changes in semen odor, one should be vigilant and go to the hospital for examination in a timely manner if necessary, and not take it lightly.
