Normal sex life can not only promote husband and wife love, family harmony, but also help the woman's disease prevention and cancer prevention
rabbit vibrator , the latter should be attributed to male semen.
In a biological experiment, German medical scientists accidentally found that men's semen contains an important antibacterial substance-semen cytoplastin, which is a protein with special function. Once it enters the bacterial cell, it can prevent the synthesis of bacterial ribonucleic acid. Ribonucleic acid is an essential biochemical substance to form proteins, and its synthesis is blocked so that bacteria can not grow.
Normal sex life can not only promote husband and wife love, family harmony, but also help the woman's disease prevention and cancer prevention, the latter should be attributed to male semen.
Laboratory culture found that semen cytoplasmin can kill staphylococci, streptococci and other pathogenic bacteria like penicillin, streptomycin and tetracycline. A gynecological examination was conducted on 100 women who had been married for more than 30 years and had harmonious sex life twice a week. The results showed that only 10% of them suffered from gynecological diseases such as vaginitis, cervicitis, endometritis and salpingitis, which was much lower than that of women who had less normal sexual life. The reason is that women with normal and harmonious sex life, because the semen of her husband enters the vagina regularly twice a week, and gradually reaches the uterus and even the fallopian tube through the cervix, thus playing a useful role in disinfection and sterilization of these parts.
Studies have also found that semen plays a key role in maintaining the balance of hormones in women, which can prevent or reduce the occurrence of some cancers. A six-year survey of 300 married women by US researchers found that women between the ages of 35 and 62 whose husbands used condoms had a five times higher incidence of breast cancer than those who took contraceptive and other forms of contraception.
According to the data, semen also has a certain preventive effect on bowel cancer. Men use condoms for contraception during sex, and the incidence of rectal cancer in women is much higher than that of women who use other methods of contraception.
Sex makes women smarter.
For a long time, experts from various countries have been working on ways to make people smarter. Recently, German scientists have found that the easiest way to make people smarter is to have regular sex. Regular sex can not only excite the body, but also stimulate the brain, making the brain extremely active, making people smarter, the study said. And this effect will be more obvious in women. The study was published on the famous Ananova website in the UK.
German scientists say a healthy and regular sex life can encourage the body to secrete more peptides.
Worner Habermeier, a member of the Hamburg Medical Research Association, who led the study, said that for a long time
anal dildo , many people mistakenly believed that having sex not only makes people physically excited and enjoyable, but also consumes energy. it has even been suggested that regular sex will shorten men's life expectancy. Now Habermel tells you that regular sex is very good for both men and women, making both men and women smarter. Habermeier explained that when couples devote themselves to sex, the brain becomes extremely active, which increases the production of adrenocortical hormones, which in turn stimulates the body to secrete more peptides.
Habermel explained that peptides have protein characteristics and are a kind of intermediate substances which are composed of amino acids but different from proteins found by biochemists in the process of in-depth study of proteins. It is a compound that can connect multiple hydroacids to each other and plays a huge role in various systems of the human body.
The famous growth hormone or human growth hormone is a linear peptide, and the peptide can also soothe the mind. A polypeptide in women stimulates luteal secretion in female organs, causes ovulation and promotes estrogen synthesis. More importantly, if the number of polypeptides in the human body increases, it can significantly improve the human immunity.
Habermeier has found that regular sex can lead to an increase in serotonin secretion in the body, which leads to an increase in memory.
Scientists say that the key to determining whether a person is smart or not lies in his intelligence. Intelligence includes many aspects, such as synthesis and reasoning, but memory ability is obviously very important.
As early as last year, Dominique de Quervain of the University of Zurich in the United States and his colleagues did experiments on serotonin. By comparing the two groups of people, they found that an increase in 5HT2a serotonin in the brain improved short-term memory. Scientists say this is the first time that serotonin, which is associated with memory, has been discovered.
Habermeier also conducted a comparative study of memory and serotonin in hundreds of couples and found that couples with a happy sex life had a relatively better short-term memory than the average couple, and accordingly, they also secrete more serotonin during sexual excitement. As a result

A happy sex life can make women in a better mood and mental state, and make them smarter.
In the survey, the researchers also found that in a cold winter with shorter sunshine

Habermeier points out that women are inherently more sensitive to changes in the weather than men, not simply sentimental, but because their body structure is very different from that of men. As soon as winter comes, serotonin in the female brain will be secreted abnormally due to shortened sunlight, leading to circadian rhythm disorders and endocrine disorders. Endocrine disorders are known as "the source of all female diseases", which can lead to symptoms such as slow response, fatigue, memory loss, neuroticism, poor sleep quality, headache and fear, resulting in emotional depression and mental disorders. In particular, women who work in front of indoor computers all the year round and seldom exercise are more likely to suffer from winter depression.
In this case, regular sex life is particularly important, because it can greatly increase the level of serotonin in the blood of the female brain and help prevent circadian disorders and endocrine disorders. And the serotonin is the same chemical as the most commonly used antidepressants.
Worner Habermel said that when people apply the experience gained from sex to other areas of life that have nothing to do with sex, people will become more confident and intelligent.
