What is the best contraceptive method afterward?

Many friends do not want to get pregnant, so they will take contraceptive measures before having sex to prevent accidental pregnancy. However, some friends often forget to take contraceptive measures for the sake of momentary pleasure, so they often use some contraceptive methods. In fact, there are many ways to use contraceptive methods afterwards. You can choose according to your own situation. So what is the best contraceptive method afterward?

Post-coital contraceptive methods can be generally divided into two categories: medical methods and mechanical methods. Drugs are further divided into hormonal and non-hormonal drugs.

Hormonal drugs, commonly used in China are contraceptive pills for visiting relatives. Many visiting relatives medicines still need to be taken before sexual intercourse. Among them, Anti-Pregnancy No. 53 only requires one tablet to be taken immediately after each sexual intercourse, and one tablet to be taken the next morning after the first sexual intercourse. After that, one tablet should be taken every day. After taking fourteen tablets, the contraceptive effect is 99.5%. Other hormonal post-coital pregnancy pills include simple estrogen, namely ethylphenol. It needs to be taken for 5 days after each sexual intercourse, twice a day, 25 mg each time, with an effectiveness of more than 99%, but the gastrointestinal reaction is severe and difficult for people to accept.

The third type of post-coital hormone medicine is a combination of estrogen and progesterone, known as tetra-estrogen abroad. That is, the medicine is taken twice within 72 hours after sex, with a 12-hour interval between them. Each dose of ethinyl estradiol 50 micrograms and 18-methylnorhenothindrone 250 micrograms has a failure rate of 0-1.6%. Side effects are the same as before. Scientists from all over the world have spent a lot of effort in searching for non-hormonal drugs, but so far most of them have remained in animal experiments. The only one used on humans is danazol, with a success rate of 98-99.1%.

In fact, many people also use the emergency contraceptive method, which is a menstrual regulator, also known as a menstrual induction and pregnancy-stopping drug. It can induce menstruation and cause spontaneous abortion even if a fertilized egg has been formed. Another method is to use an intrauterine device placed in the uterus. If it is very effective within five days, it can prevent the endometrium from implanting a fertilized egg.

The above is an introduction to the best contraceptive method after sex. If you have not planned to have children, you should take some contraceptive measures as early as possible, because emergency contraception after sex can cause certain harm to women's bodies, especially long-term use of emergency contraceptives. In severe cases, it can lead to lifelong infertility.
