What does man's semen smell like?

　　The first thing to explain is that whether it is semen, saliva, gastrointestinal fluid, blood, lymph, etc., they are all body fluids of the human body. Of all the natural body fluids in the human body, the one with the most distinctive smell is semen. Semen is not a pure fluid like other body fluids, it is a mixed fluid. Semen contains nothing but what we know sperm In addition, there are various secretions such as seminal vesicle fluid, epididymal fluid, prostatic fluid, vas deferens, and urethra. Among them, seminal vesicle fluid accounts for about 20% and 60% of prostatic fluid.

When arginine is exposed to the air, it oxidizes and emits a chestnut flower smell. The oxidation of arginine must be through sexual excitement ejaculation When the prostate secretes prostatic fluid and seminal vesicle fluid, they work together to produce odor. clinical It was found that prostate secretions obtained through rectal massage are called "resting secretions" and also contain arginine, but they cannot be oxidized and generally do not have the smell of natural semen. Therefore, the smell of normal ejaculated semen comes from the help of prostate fluid and seminal vesicle fluid. Semen lacking this special smell indicates damage to prostate function. This smell is often not found in the ejaculated semen of many patients with prostatitis.

　　According to research, all animal semen has an odor. Especially in lower animals, the smell of semen is also a message of sexual activity and sexual selection between the sexes, which is mainly transmitted by smell. The smell of pheromones emitted by many mammals during estrus can be detected. Some animals cannot mate when they lack pheromones. Although humans have continued to expand their access to sexual stimulation during evolution, the sense of smell has given way to sensory organs such as vision and touch in sexual selection. But in recent years, physiologists have discovered many kinds of secretions in the human body that can affect the sexual cycle of the opposite sex or the same sex. For example: a secretion called "copulins" produced by a woman's vagina is most abundant during the ovulation period and is most attractive to men. Androstenone in men's sweat and urine can arouse sexual desire in the opposite sex. The body surfaces of both men and women will emit an imperceptible body odor substance called phenanthrene, which affects both same-sex and opposite-sex behaviors. It is another form of communication between the sexes. This series of research findings has made physiologists take a new look at the sense of smell, believing that it may still be one of the most important senses of the human body. It is necessary to conduct in-depth research on its mysterious and unpredictable characteristics.

　　It is not necessary to eliminate the odor of semen, nor can it be eliminated. Being clean isn't a bad thing, but using too much deodorant or perfume will rob you of the sexual magic of natural body odor.
