It is most important that the condom does not carry the size with you.

Some people think that accidental one-time life will not lead to pregnancy. According to incomplete statistics, the most common reason among women who are in the flow of people is that there is a chance of being pregnant. It is considered that pregnancy is not so easy, and the chance of a one-time pregnancy is very low. This is a very wrong point of view. Every one-time life has the risk of pregnancy. Don’t be lucky, or choose the contraceptive method that suits you. Condoms: must be used correctly in some countries and regions, often have street publicity campaigns to distribute condoms, this is not only for popular science contraception, but also because male condoms are currently the only ones that can effectively prevent gonorrhea, syphilis and AIDS. A method of contraception that spreads the spread of disease. Most male condoms are made of a thin layer of latex that protects the penis and prevents sperm from entering the female reproductive tract by physical barriers. Even so, this method of contraception is not foolproof. In the first year, the condom is perfectly used (strictly used according to instructions), the chance of pregnancy is about 6%, and the probability of pregnancy for typical use (discontinuous use) is about 16%. Therefore, in order to achieve a safe contraceptive effect as much as possible, men need to use condoms correctly. First of all, condoms have different specifications. Men should choose the appropriate model according to the size of the penis when they are erect. If the condom is too large, it will fall off in the vagina. If it is too small, it will be squeezed and the semen will flow into the vagina. At the same time, condoms can only use water-based lubricants. Vaseline, liquid paraffin, face oil, cooking oil, etc. can increase the brittleness of the condom and accelerate its rupture in a short time. If the condom is found to have a hole or slippage during use, it is still unsafe to replace the condom. If the semen overflows into the vagina, it may cause the contraception to fail. In this case, it is necessary to take remedial measures in time and take emergency within 72 hours. The contraceptive, the sooner you take it, the better. In many Western countries, emergency contraception has become an effective remedy for contraception. Another point to note is that because barriers such as condoms can affect the feelings and quality of sex, some men will choose to wear them before ejaculation to ensure safety. In fact, this often leads to contraceptive failure, because the penis flows out before ejaculation. A small amount of sperm in the liquid can still cause a woman to become pregnant. Moreover, not wearing a condom can increase the risk of sexually transmitted diseases. In addition, Shen Jian does not recommend that men carry condoms with them, although this can help you prepare for the occasion, but condoms need to be properly stored to ensure Safety”. If stored in a hot and humid environment, it will become thin and brittle, easy to break holes and tear, and the condom should be stored in a dry and cool safe environment as much as possible. In fact, it is very convenient to buy condoms now, so you don’t have to carry them with you. Commercially available condoms are mainly made of rubber. Although the harm to the human body is relatively small, friends who are allergic to some rubber or lubricating spermicides need to pay attention. If you use a condom, there will be many adverse reactions, and some people can switch to other methods of contraception. Female Barrier Contraception: Requires training relative to male condoms. Women’s barrier contraceptive methods, such as vaginal diaphragms, cervical caps, and contraceptive sponges, need to be safely and effectively used under the guidance and training of physicians. In addition, due to the composition of female condoms, It is constructed and used so that it does not block the spread of exogenous pathogenic microorganisms such as bacteria, fungi and viruses. The vaginal diaphragm is a round rubber cap with an edge that can be deformed and inserted into the cervix, which prevents the sperm from entering the uterus. Because the size of the diaphragm varies, the health care physician should provide the appropriate model for the consumer and tell the woman how to use it. When in use, the diaphragm should be completely covered on the cervix without causing discomfort. When a woman gains more than 4.5 kg or more, has applied the diaphragm for more than 1 year, or has had a child or a miscarriage, she needs to choose another diaphragm because the size and shape of the vagina may change. In the first year of diaphragm application, according to whether the diaphragm is used correctly and the time of use is correct, the pregnancy rate of women is 3% to 14%. The cervical cap is similar to the diaphragm, but it is smaller than the diaphragm and has a hard texture that fits snugly over the cervix. Health care providers should provide consumers with appropriate cervical caps. In the first year of perfect use, the premature female pregnancy rate is about 9%, and the typical use is about 18%. The probability of pregnancy in a woman who has been bred is twice that of an unfertile woman, because childbirth changes the cervix and makes it difficult to use safely. Another barrier method, the contraceptive sponge, is a contraceptive device that combines a barrier method and a spermicide. It is used in a manner similar to a tampon, inserted into the vagina before sexual intercourse, and covered with the cervix. Reject sperm into the uterus. At the same time, since the contraceptive sponge contains spermicide, sperm movement can be avoided. However, this method of contraception is not as effective as an oral contraceptive or an intrauterine device, and it cannot prevent the spread of sexually transmitted diseases. The contraceptive sponge is easy to use and provides continuous protection within 24 hours, but it is difficult to remove. Some people may develop allergic reactions, vaginal dryness or irritation. More than 5 kg, the application of the diaphragm has been more than 1 year, or if you have had a child or abortion, you need to choose another diaphragm, because the size and shape of the vagina may change. In the first year of diaphragm application, according to whether the diaphragm is used correctly and the time of use is correct, the pregnancy rate of women is 3% to 14%. The cervical cap is similar to the diaphragm, but it is smaller than the diaphragm and has a hard texture that fits snugly over the cervix. Health care providers should provide consumers with appropriate cervical caps. In the first year of perfect use, the premature female pregnancy rate is about 9%, and the typical use is about 18%. The probability of pregnancy in a woman who has been bred is twice that of an unfertile woman, because childbirth changes the cervix and makes it difficult to use safely.
