1. Does semen contain many calories?
Answer: False. Semen is not milk. If semen really contains a lot of calories, there will be an evil person who lives on it in human history. The main components of semen are water, VC, calcium and magnesium, and a small amount of fructose, but each serving contains only 5~7 calories, and it does not contain amifostine, which is lower than the energy of porridge.
2. Does semen contribute to the disinfection of female private parts?
Answer: Really. Experiments show that there is an antibacterial substance in semen-semen cytoplasm, which can kill staphylococcus, streptococcus, pneumococcus and other pathogenic bacteria. Therefore, it can help female genitals avoid microbial invasion. Women who have not had sex for a long time are more likely to suffer from diseases such as female genital inflammation, endometritis and salpingitis.
3, semen antidepressant?
Answer: Really. LazarGreenfield, an American surgeon, made a survey and found that female college students have different degrees of mental depression after wearing or not wearing ooxx. According to the results of Bayesian Depression Scale, ooxx without condom is more antidepressant.
4. Can semen moisturize a woman's skin?
Answer: False. It is not semen that moistens women, but love. Because moderate sexual intercourse will accelerate blood circulation, balance metabolism, make skin smooth and tender, and play a role in preventing and treating skin diseases.
5. Improve the disease resistance of the immune system?
Answer: Really. Too clean environment will make people's bodies fragile. Occasionally touching some other people's body fluids will make our body's immune system open, thus forming a virtuous circle. In the future, a little sudden bacterial attack will not make your body collapse.
6. Can sexual life prevent heart disease?
Answer: False. The relationship between sex and heart disease is far more complicated than a "prevention". Although sex can promote blood circulation and enhance heart function and vital capacity. But sudden cardiac death caused by sex occurs all over the world.
7. Can semen relieve pain?
Answer: Really. But the effect is not as obvious as real painkillers. A large number of medical institutions have confirmed that sexual life can stimulate the central nervous system of the brain and secrete a chemical called amine polyphenols, which is quite effective in relieving pain, but it is limited to mild pain such as headache and brain fever, and is not suitable for injuries such as hand and foot fractures.
2. The reason why men have less sperm.
1, endocrine abnormality
The normal spermatogenic function of men depends on the normal function of hypothalamus-pituitary-gonad axis, and any obstacle will affect the spermatogenic function. Other diseases, such as thyroid gland and adrenal gland, can also affect gonadal function and cause oligozoospermia.
2, cryptorchidism
It is reported that about 30% ~ 60% of patients with unilateral cryptorchidism are infertile, about 50% ~ 100% of patients with bilateral cryptorchidism are infertile, and about 9% of patients with oligozoospermia are cryptorchidism. In addition to the degeneration of seminiferous tubules, cryptorchidism itself may also damage the other testis to varying degrees, which may be due to the influence of anti-sperm antibodies produced by cryptorchidism on normal testis.
3. Inflammation of genitourinary system
Include orchitis, epididymitis, seminal vesiculitis, prostatitis and urethritis. These patients account for the largest proportion of oligozoospermia. Genitourinary tract inflammation can directly affect the spermatogenic function of testis, and can also produce anti-sperm antibodies in blood or semen, affecting the pH of semen. The direct killing effect of pathogens on sperm can cause sperm reduction.
4, varicocele
Infertility caused by varicocele accounts for 30% ~ 40% of male infertility. Due to the increase of testicular temperature and toxin deposition, the spermatogenic function of testis is affected, resulting in oligozoospermia and severe azoospermia. The initial symptoms of varicocele are not obvious, and in severe cases, scrotum can be swollen, which looks like an earthworm-like blood vessel mass. Semen examination showed that the number of sperm decreased, the motility was poor and the number of abnormal sperm increased.
5. The scrotum temperature is too high.
The seminiferous tubules in the testis, which are specially used to make sperm, are very sensitive to temperature changes. The suitable temperature of this part is 2 ~ 3℃ lower than the human body temperature. Too high temperature is easy to inhibit the survival and maturation of sperm, leading to the decrease of sperm quantity or fluidity in semen. Therefore, male friends should wear less tights, go to saunas less, avoid electromagnetic radiation and high temperature, and develop good living habits.
