Contraception after the event

Contraception is a very common thing. There are many methods of contraception. When taking contraception, you can choose before or after the event, which is very helpful in preventing pregnancy. However, it should be noted that the choice of contraceptive pills cannot be done arbitrarily, otherwise it will cause great harm to women's health. This should also be noted. How to choose the contraceptive method after the event?

Many women have the habit of forgetting to take pills before having sex, so when choosing a contraceptive method after sex, they should choose one that suits them. This way, there will be no harm to their health, and they can use it with confidence.

Emergency contraception methods:

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-pregnancy pills include simple estrogen, i.e. ethylphenol, which needs to be taken for 5 days after each sexual intercourse, twice a day, 25 mg each time, with an effect of more than 99%, but the gastrointestinal reaction is severe and difficult to accept. There are also progestins. A single dose of 0.4 mg of 18-methylnorhenothindrone after sexual intercourse is 98.3% effective, but it has the disadvantage of irregular bleeding.

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 had a failure rate of 0-1.6%. Side effects are the same as before. The mechanism of these hormonal post-coital contraceptives is not single. They can interfere with sperm activity and capacitation, fallopian tube motility, inhibit or delay ovulation, fertilization, corpus luteum function, endometrial development, implantation and embryo development, etc.

Scientists from all over the world have spent a lot of effort 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%.

The more ideal post-sex contraceptive pill is a menstrual regulator, also known as a menstrual induction and pregnancy-stopping drug. That is, when a woman's menstrual period is overdue a few days later, taking this medicine can induce menstruation. Even if she is pregnant, this medicine can cause a spontaneous abortion of the very early embryo. The more mature drugs of this type include RU486, which was successfully developed in France and has also been mass-produced and marketed in my country. In recent years, RU486 has been successfully used for contraception and is expected to be used clinically soon.

Through the above introduction, we have a good understanding of the post-coital contraceptive methods. Therefore, women can choose the above methods for contraception. However, if women feel unwell after taking contraceptive pills, they also need to go to the hospital for examination to see the specific condition of the body, which will be of great help in the treatment of the disease.
