Any man or woman who has had sexual experience will notice that the semen ejaculated by a man has a strong and special odor. Some people feel disgusted by this smell, saying it is extremely unpleasant; Some people find the fragrance refreshing and exciting. These two completely opposite feelings are closely related to physiological and psychological factors such as both parties' level of sexual desire, depth of spiritual and physical integration, and attitude towards sexual behavior. What scientists are interested in is where does the odor come from and what is the significance of its existence?
Semen, like saliva, gastrointestinal fluid, blood, and other bodily fluids, belongs to the human body, but only semen has the most significant odor. Semen is not as pure as other bodily fluids, it is a mixture. In addition to sperm, other seminal plasma components are composed of prostatic fluid, epididymal fluid, seminal vesicle fluid and various secretions of urethra and vas deferens.
The odor of normal semen is emitted by a chemical substance called arginine after oxidation, much like the odor of chestnut flowers. Arginine is one of the various important components contained in prostate secretions. The oxidation of arginine must involve the seminal vesicle fluid. The prostatic fluid obtained by rectal massage generally does not have the smell of natural ejaculation semen. It can be seen that the odor of normal ejaculation semen comes from the prostate gland, but it 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.
As for the physiological significance of the special smell of semen, it is speculated that it may be related to sexual desire and behavior. In lower animals, the information of sexual activity and sexual selection mainly depends on smell; Many mammals emit a special odor during estrus to attract the opposite sex. Although the way of human accepting sexual stimulation has been expanding in evolution, the position of smell in sexual selection has given way to vision. But in recent years, scientists have discovered many secretory substances in the human body that can affect the opposite sex through smell, indicating that smell may still be one of the important sensory organs in the human body, and it is necessary to conduct in-depth research.
As for the odor of semen, it is not necessary to eliminate it, nor can it be eliminated. It is natural to love cleanliness, but it is a clich é d idea to consider sexual behavior and semen as "dirty" things. In addition, it warns people who love cleaning that excessive use of deodorant or perfume and other "external objects" will make you lose the sexual charm of natural body odor.
