Is strong fishy smell in semen a disease? The truth is this

Many women say that after having sex with their husbands, the semen left on their bodies emits a "fishy smell" that makes them feel very uncomfortable. Some men's semen seems to have a particularly strong smell. Is this normal? What is the reason for a man's semen to have a strong fishy smell?

Semen is a mixed fluid

Semen, like saliva, gastrointestinal fluid, and blood, is a body fluid, but only semen has the most noticeable smell. Semen is not as simple as other body fluids, it is a mixed fluid. In addition to sperm, other seminal components of semen are composed of prostatic fluid, epididymal fluid, seminal vesicle fluid, and various secretions from the urethra and vas deferens.

Semen tastes like chestnut flowers

The smell of normal semen is emitted by a chemical called arginine after oxidation, which is very similar to the smell of chestnut flowers. Arginine is one of the many important components contained in prostate secretions. The oxidation of arginine must be involved in the seminal vesicle fluid. The prostate fluid obtained through rectal massage generally does not have the smell of natural ejaculated semen.

The smell of semen comes from the prostate

It can be seen that the smell of normal ejaculated semen comes from the prostate, but it is emitted with the participation of seminal vesicle fluid. The lack of this special smell in semen often indicates prostate function damage, and the semen of many prostate patients often does not smell this smell.

Semen odor is related to sexual desire and sexual behavior

As for the physiological significance of the special smell of semen, it is speculated that it may be related to sexual desire and sexual behavior. In lower animals, information about sexual activity and sexual selection between the sexes is mainly transmitted through smell; many mammals will emit a special smell during the estrus period to attract the opposite sex.
