What is the nutritional value of semen
Many couples have the habit of oral sex when making love, even if the taste is not good, but in oral sex may be a woman will eat part of the sperm.
Is sperm good for your health as a liquid that only appears during orgasm in men? Is there any nutritional value?
Let’s study it together.
Semen is not nutrient fluid
Some people like oral sex, and will swallow semen, think there is better nutrition, in fact, this idea is too exaggerated sperm.
In fact, semen consists of two parts: sperm and seminal plasma. The main component of seminal plasma is water, accounting for more than 90%. Other components include fat, protein particles, free amino acids, minerals (calcium, magnesium, potassium, zinc), enzymes, fructose, and so on, which are similar to those in plasma.
Spermatozoa do have a lot of trace elements, which seem to be nutritious, but the content is not high.
If compared with food, semen is even worse. Take a glass of about 250 milliliters of milk as an example, which contains 8 grams of protein, 10 grams of fat, 13 grams of sugar, and the same amount of soy milk contains 11 grams of protein, 5 grams of fat, 29 grams of sugar, which are much higher than the nutritional value of semen.
Then from the point of view of the physiological mission, semen is not mainly to play a nutritional role, but to have children and reproduce the needs of the race. Therefore, there is no scientific basis for treating semen as a nutrient solution.
Semen is resistant to disease
Although semen is not a nutrient solution, it is a good way to prevent diseases, especially in the field of cancer, which is the latest discovery by Korean scientists.
They extracted zinc and other minerals from semen and injected them into a culture medium containing epithelial ovarian cancer cells and normal ovarian epithelial cells for just 48 hours. Ovarian cancer cells have a mortality rate of 81%, compared with 37% of normal cells.
This suggests that the normal husband and wife’s life may be able to effectively prevent women from suffering from ovarian cancer.
Statistics show that women who are married for more than 30 years and have sex twice a week have a much lower incidence of gynecological inflammation, such as vaginitis and cervicitis than those who do not have a normal sexual life.
Ejaculation and urination do not occur at the same time
Some women worry that men will urinate at the same time when they ejaculate. Wouldn’t that be bad?
Of course, men’s semen and urine are expelled from the same channel, but under normal circumstances, semen and urine will not be discharged at the same time. This is due to a special structure in the urethra-the membranous sphincter of the urethra.
When a man is sexually excited, the sphincter of the bladder and the sphincter of the urethra contract at the same time, creating a small closed space between the sphincter of the bladder and the sphincter of the urethra, where sperm produced by the testicles is mixed with secretions from the prostate and seminal vesicles. To form semen.
When semen accumulates to a certain amount, or when the penis is stimulated enough to produce an orgasm, the sphincter of the urethra opens due to relaxation, and the semen is ejected from the orifice of the urethra.
The bladder sphincter does not relax, so the voiding channel remains closed and the urine does not flow out at the same time.
In addition, the brain also plays a role in monitoring. In other words, the brain decided that at this point “not allowed to urinate”, so refused to issue avoiding “instruction.”
Therefore, under normal circumstances, ejaculation is not the time to excrete urine.
Normal semen smells weird
Semen has an odor, and the smell is strong and strange, some people dislike it and dislike it, some people feel the faint fragrance and excited. These two diametrically opposite feelings are closely related to physiological and psychological factors such as the level of sexual desire and the attitude to the sexual behavior of both men and women.
In fact, semen and saliva, gastrointestinal fluid, blood and so on are body fluids, but only the smell of semen is the most significant.
The “reason” for this “strange smell” is from the oxidation of a chemical called ammonia, smelling like chestnut flowers.
Seminal ammonia is one of the most important components in prostatic secretion, and its oxidation must involve seminal vesicle fluid. Therefore, the smell of seminal vesicle fluid comes from the prostate and emanates with the assistance of seminal vesicle fluid.
Therefore, if the man’s semen does not have such a strange smell, it is suggested that prostate function may be damaged, but need to pay attention.
In addition, the smell of semen may also be related to people’s sexual desire and sex life. Because to this day, the smell is still one of the most important sexual sensory organs in human beings. The strong smell of semen stimulates a person’s libido to a certain extent.
