Both men and women need to learn about physiology so that they don't make jokes. Of course, there are some physiological knowledge that can be useful and can provide positive help in maintaining good health. Some people fall into misunderstandings, listen to rumors, and may make mistakes. So, what physiological knowledge is wrong and cannot be listened to?
1. Contraception can be obtained during the safe period
Many people may make mistakes when they believe that women can use effective contraception during the safe period. Although it is easier to conceive during the safe period than during ovulation, it is not guaranteed that you will not get pregnant as long as you have intercourse during ovulation. Some people do not calculate the safe period accurately, or have early ovulation, delayed ovulation, etc., which may cause unplanned pregnancy. Therefore, people who want effective contraception should not go without any protection during the safe period.
2. Gynecological diseases will only occur when there is sexual life
It is nonsense that women are only at risk of developing gynaecological diseases if they have sex, although many gynaecological problems in women are related to sexual life, such as lack of personal hygiene, and certain pathogens can take advantage of the situation and develop into diseases. However, not all gynecological problems are caused by this reason, and there are many types of gynecological diseases, and the triggering factors of different diseases are different. Some people do not pay attention to local hygiene, or the body's immunity is poor, and they are also at risk of disease. It is necessary to understand how the disease is caused and take preventive measures in all aspects.
3. The color of the private parts is black and has rich sexual experience
The darker the color of women's private parts, the richer the life, which is the misunderstanding of many people, thinking that women will have frequent sexual life to have the performance of darkening the color of their intimate parts, but the actual frequency of sexual life is not directly related to the change of the color of the skin of the private parts, some people are born with dark skin, and some people gradually age with age, endocrine changes, and hormone levels will also lead to local pigmentation, so the color changes, and the skin color will not change because of frequent sexual life, which should be clear.
4. Abstinence can improve sexual function
Male abstinence can improve sexual function, and at the same time make their sperm quality, sufficient vitality, and good fertility, which is a rumor that many men listen to, and may abstain from sex for a long time before trying to conceive. However, abstinence is not a feasible method, abstinence for too long will affect male libido, and even sperm can not be renewed normally and the quality deteriorates.
5. The longer you have sex, the better
The longer the male insists on the process of sexual life, the better the representativeness, the actual length of time and the strength of sexual ability is not directly related, some people do not ejaculate for a long time, in fact, it is related to physical problems, such as the occurrence of ejaculation disorder, there is difficulty in ejaculation, the possibility of more than half an hour can not ejaculate normally. If there is such a phenomenon, don't think it's a good thing, it may be an early warning of some diseases, and you should check in time to understand the cause.
