On the eve of World Contraception Day, the results of a survey of more than 4,000 people in Europe, Asia-Pacific, North America and Latin America showed that more than 1/3 of the respondents believed that extremely low-reliability contraceptive methods such as in vitro ejaculation methods are effective. 42% of respondents used IVF as a regular contraceptive method. Professor Cheng Linan, chairman of the Family Planning Branch of the Chinese Medical Association, pointed out that the current awareness rate of contraceptive methods among people of childbearing age in my country is still very low compared with developed countries in the world. There are still quite a few young people who do not know what safe and reliable contraception is. Methods: Incorrect contraceptive methods such as in vitro ejaculation not only increase women's chances of unwanted pregnancy, but also damage men's prostate health. Frequent use of this method may also affect sexual function. Experts explained that a man's penis is erect and hard before ejaculation. If he forcibly stops sexual intercourse and withdraws his penis at this time, it will cause dysfunction of the central nervous system and the ejaculatory center in the lumbar region. Over time, it will easily induce functional inejaculation. . At present, the more scientific contraceptive methods mainly include: condoms, short-acting contraceptive pills, intrauterine devices, etc. Among them, short-acting contraceptive pills should be the safest and most effective method of contraception.
