I feel it necessary to explain after receiving the following email:
Hello:
I'm still in school, and I'm a graduate student. My boyfriend and I are separated, so we are together every holiday. After each sexual intercourse, I take emergency contraception. I didn't know at first that this medicine was harmful to health and it was so serious. I eat about a dozen times a year, and now I'm worried. Will there be problems with my health? Knowing that this medicine is harmful, I bought a long-acting contraceptive. Is this medicine less harmful to my health?
I look forward to your reply. thank you
XXX
The answer is as follows:
1. This drug has only been on the market for a few years. It's hard to say what will happen if you eat it more than three times a year (because many people eat it themselves, and doctors can't grasp the changes after eating it).
This medicine is not poison, so don't worry too much.
3. This drug is a sex hormone drug, which contains substances similar to estrogen and progesterone. Therefore, it is an emergency contraceptive, that is to say, it should not be taken frequently, and it cannot be treated equally with conventional contraceptives, indicating that its side effects are greater than those of conventional contraceptives (because its dosage is several times higher than that of conventional contraceptives).
At present, we only know that taking Yuting regularly will lead to menopause, menstrual cycle disorder and other adverse effects. At present, we don't have clinical data (that is, no one has published such a paper, let alone emergency contraception, not conventional contraception).
4. I suggest that in this case, if your boyfriend is with you for less than 13 days, you can take [No.53 contraceptive] as a family visit contraceptive.
Or take short-acting contraceptives directly and regularly throughout the year. Don't miss it.
5. Alas, birth control pills are all sex hormone drugs, which affect the balance of sex hormones in women. The principle of contraception is to inhibit ovulation.
If you don't take it under the guidance of a doctor, you will break this balance. It is easy to break the balance, but it is troublesome.
However, if you don't have menstrual cycle disorder, you don't have to be so worried and anxious. Remember not to take it so frequently in the future.
If there is cycle disorder, it is recommended that there is nothing special after western medicine examination. It is recommended to go to a local regular Chinese medicine hospital and consult a Chinese gynecologist.
Western medicine is not as effective as Chinese medicine.
Hormone emergency contraception
Emergency use of hormonal drugs after sexual intercourse to remedy contraceptive effect, it is best to go to the family planning guidance department or maternal and child health care department under the guidance of a doctor. Common methods:
(1) No.53 (or visited by other family members) take 1 tablet immediately after sexual intercourse or the next morning, and no later than 48 hours, then take 1 tablet every night for 3 consecutive nights, and then take1tablet every other night for 4 consecutive times, with a total of not less than 8 tablets.
(2) Take E-E (ethinylestradiol) 0. 1 mg and LNG (levonorgestrel 18)0.5mg within 72 hours after sexual intercourse, and take it again 12 hours.
(3) Take danazol 400-600 mg 12 hour after sexual intercourse.
(4) Take mifepristone orally within 5 days after sexual intercourse. The lowest effective dose is currently being studied, which may be 10-25mg.
(5) High-dose estrogen can be used in remote drug-deficient areas, and diethylstilbestrol 25 mg can be used as soon as possible after sexual intercourse, twice a day for 5 days, which can cause vomiting.
After taking these drugs according to the above methods, if ovulation has not yet occurred, the drugs may inhibit ovulation. If ovulation has occurred or even fertilization has occurred, drugs may interfere with the normal transport of fertilized eggs, change the development of endometrium, and make fertilized eggs unable to implant, thus achieving the purpose of contraception.
Emergency contraception knowledge
order
Emergency contraception refers to an "emergency" remedial measure taken after unprotected sexual life or contraceptive methods fail (condom rupture, slippage, missed use of contraceptives, miscalculation of safety period, etc.). ) prevent unwanted pregnancy, reduce induced abortion and protect the physical and mental health of women of childbearing age. In order to make women better understand and master emergency contraception methods, we specially compiled this handbook "Emergency Contraception Knowledge". At the same time, it is also a reference for family planning workers and medical staff. Sexual life is an important part of married life, but sometimes embarrassment and accidents will inevitably occur. We present this manual to our dear friends, hoping to eliminate your anxiety, relieve your mental stress and provide effective help when you need it.
Beijing Guolian Medicine Management Co., Ltd.
1. What is "emergency contraception"? What's the difference between it and conventional contraception?
"Contraception" is well known, and people are familiar with various contraceptive methods, such as intrauterine devices, oral contraceptives, contraceptive needles, condoms, subcutaneous implants and vaginal rings. "Emergency contraception" is different from conventional contraception. This contraceptive method is a temporary emergency method and a remedial measure. Emergency contraception refers to an "emergency" remedial measure to prevent unintended pregnancy, reduce abortion and protect women's physical and mental health after unprotected sexual life or contraceptive methods fail (such as condom slipping or rupture, uncontrolled sperm discharge, missed use of conventional contraceptives, and miscalculation of safety period). ).
The purpose of using emergency contraception is to prevent embryo implantation and pregnancy. Some people call emergency contraception "postpartum morning" or "postpartum morning" inappropriate, because it means that it needs to be taken immediately after sexual intercourse or must be taken the next morning. Actually, the emergency contraceptive-An Ting takes it within 72 hours after sexual intercourse, which is effective. Experts suggest that women of childbearing age, especially newly-married families, should always keep 1 ~ 2 boxes of An Ting, an emergency contraceptive, to prevent unintended pregnancy.
Emergency contraception can include taking medicine or placing intrauterine device (IUD). Emergency contraceptive or intrauterine device is not a special contraceptive, but it is different from conventional contraceptive methods in time, dosage and method.
Second, why emergency contraception?
Although contraceptives have made great progress, there are still many shortcomings. Nearly 30 million pregnancies worldwide every year are caused by contraceptive failure. In addition, due to various reasons, no contraceptive measures are taken in the same room, so many unintended pregnancies are terminated through induced abortion, which directly leads to the death of at least 200,000 women every year. At present, there are100000 cases of induced abortion every year in China. According to statistics, one-third to one-half of them are unintended pregnancies caused by not taking contraceptive measures. If they know or have access to emergency contraception services, the number of induced abortions will be reduced by 3 to 4 million. Unsafe abortion has become an urgent problem. In response to this urgent task, countries all over the world have put forward the "emergency contraception" action, which shows the importance of emergency contraception.
In our daily life, we often encounter such a situation: some women miss taking conventional contraceptives, some women find condoms slipping or breaking when they are in the same room, some young partners do not take contraceptive measures during sexual intercourse, and some women are raped. After these accidents, many women are restless and helpless because of the panic of unplanned pregnancy, and can only passively expect menstrual cramps. An Ting, an emergency contraceptive, can solve the problem for these women. At least 50% ~ 70% of unwanted pregnancies can be avoided by emergency contraceptives, so that the majority of women can avoid the physical and mental harm caused by induced abortion.
Third, what harm will induced abortion cause?
(1) is easy to cause women's uterine diseases and infections;
(2) may affect future pregnancy and childbirth;
(3) A few people have lifelong problems caused by illegal abortion and unauthorized abortion;
(4) Causing serious psychological trauma to women.
4. What are the emergency contraceptive methods?
1. Take emergency contraceptive measures within 72 hours after contraceptive failure or unprotected sex-Anting. Take one tablet orally within 72 hours after sexual intercourse, and one tablet after 12 hours.
2. Place intrauterine devices within 5 days after contraceptive failure or unprotected sex-suitable for women or women who have had induced abortion.
5. Is the emergency contraceptive a contraceptive?
It must be noted that emergency contraception is not abortion, and emergency contraception is not a contraceptive. Here, I solemnly advise those friends who need abortion because of unexpected pregnancy to go to regular hospitals or family planning clinics, and never go to private clinics without medical conditions for medication or induced abortion, so as to avoid accidents and regret it!
6. What is Anting?
An Ting is an emergency contraceptive approved by State Administration of Pharmaceutical Products, which is suitable for China's national conditions. The approval number is: National Medicine Zhunzi (1998)XF- 1573. Anting has two packaging specifications, each box contains 2 or 4 tablets. At present, it is the safest, effective and convenient emergency contraceptive in China. It is used for postpartum contraception in unprotected sexual intercourse or in the same room where contraceptive methods fail (condom slippage or rupture, coitus interruptus out of control, miscalculation of safety period, etc.). Anting is produced by Shenyang No.1 Pharmaceutical Factory, a famous large pharmaceutical enterprise with a history of more than 50 years, with reliable quality assurance.
7. What are the characteristics of An Ting?
Ping 'an Anting is a pure progestogen preparation, which is safe to use. Effectively delay or inhibit ovulation, interfere with implantation, and effectively prevent unintended pregnancy.
Easy to carry and store. Users can buy directly from pharmacies or family planning departments and take them themselves.
Eight, how to take An Ting?
Oral administration 1 tablet (0.75mg) 72 hours after sexual intercourse, and oral administration of the second tablet (0.75mg) every 12 hours, a total of 2 tablets (1.5mg).
9. Why can An Ting use contraception?
An Ting is a drug for promoting pregnancy. As an emergency contraceptive, it mainly acts on hypothalamus and pituitary gland. By inhibiting the secretion of pituitary gonadotropin, the levels of follicle stimulating hormone and luteinizing hormone are reduced or disappeared, thus inhibiting ovulation. It also has a strong inhibitory effect on endometrium and affects the implantation of pregnant eggs. Anting can avoid pregnancy by inhibiting follicular development, inhibiting or delaying ovulation, affecting endometrial development and interfering with implantation.
X. What is the effect of emergency contraception? The possible side effects of taking emergency contraception-Anting and how to deal with it?
Generally speaking, taking the emergency contraceptive pill-An Ting can prevent most pregnancies. If the medication method is correct, the failure rate is less than 2%.
In order to ensure successful emergency contraception, women should have the following information:
The length must be used within 72 hours after sexual intercourse to be effective; If it has been more than 72 hours but within 5 days after unprotected sex, then the intrauterine device can be placed.
2. Women who need emergency contraception are divided into two categories: one is unwilling, accidental and unprotected sex; Second, women who failed to use contraception because of condom rupture or slippage. Because the visit time of emergency contraception is often unplanned, it is necessary to let women know about emergency contraception methods in the usual education and publicity. At the same time, we should prepare 1 ~ 2 emergency contraceptive zaoantong.
The incidence of side effects in An Ting is extremely low. Experts summarized the possible side effects and treatment methods:
(1) Nausea: The incidence of this condition is extremely low, and it usually disappears within 24 hours.
(2) Vomiting: Take it with food or before going to bed to relieve nausea or vomiting. If vomiting occurs within 2 hours after taking the medicine, you should take the emergency contraceptive-Anting 1 tablet immediately.
⑶ Irregular uterine bleeding: Some women will have a small amount of bleeding after taking the medicine, and generally do not need treatment, and the symptoms will be eliminated by themselves in about two days.
⑷ Menstrual changes: Most women have menstrual cramps as scheduled, and some women have their menstruation advanced or postponed. If menstruation is delayed for a week, you should have a pregnancy test to see if contraception fails.
5. Other side effects: breast pain, headache, dizziness and weakness, generally less than 24 hours.
XI。 Under what circumstances need to take emergency contraception, take emergency contraception-An Ting?
All existing contraceptive methods are likely to fail. When some conventional contraceptive methods fail, the possibility of pregnancy will definitely increase. Especially after unprotected sex (for example, some couples do not take contraceptive measures for some reason, and some young people are not ready to have sex. ) or sexual violence, the possibility of pregnancy will be greater. Emergency contraceptive measures should be taken immediately in the following cases:
(a) did not take contraceptive measures;
(2) The condom is damaged, slipped or improperly used;
⑶ Improper placement or premature removal of cervical cap, vaginal septum and vaginal sponge;
(4) Failure of in vitro sperm discharge;
5] ejaculate at the vaginal opening;
[6] The contraceptive method of urethra after compression is not well mastered;
Once the calculation of safety period is wrong;
(8) Only spermicides such as contraceptive suppository and medicated membrane are used for contraception during ovulation;
(9) omission of short-acting contraceptives;
⑽ IUD was found to fall off.
In any of the above cases, you should take emergency contraceptive measures as soon as possible and take emergency contraceptives-An Ting.
Twelve, taking emergency contraception-An Ting need to pay attention to what problems?
Medical research believes that pregnancy begins after the fertilized egg is implanted into the endometrium. Once implantation occurs, emergency contraception is ineffective, so emergency contraception must be used before pregnancy to prevent pregnancy. If a woman is pregnant, emergency contraception will not lead to abortion.
(1) Emergency contraception-An Ting can only remedy the previous sexual intercourse, and there can be no unprotected sexual intercourse after taking the medicine.
(2) If vomiting occurs within 2 hours after taking the medicine, you should take an antipyrine as soon as possible. If you vomit after 2 hours, you don't need to take it.
⑶ Emergency contraception cannot replace conventional contraception.
⑶ Take Antin 1 tablet 72 hours after unprotected sexual intercourse or contraceptive failure, and then take 1 tablet every 12 hours, a total of 2 tablets.
5] In order to ensure that you can take the medicine on time, it is recommended to take it in the morning and evening.
Is emergency contraception harmful to the fetus? When is it not appropriate to use emergency contraception-An Ting?
The survey shows that some women continue to take emergency contraceptive measures without knowing that they are pregnant, but this has not increased the birth defects or other problems of babies. Therefore, there is no reason to think that taking an emergency contraceptive pill once will lead to birth defects.
Emergency contraception can greatly reduce the rate of induced abortion by preventing unintended pregnancy. In some developed countries in Europe, the use rate of emergency contraception is high, and the rate of induced abortion is also low; However, in China, although the number of people using emergency contraception has greatly increased in recent years, the emergency contraception method is far from universal, which needs to be widely publicized and introduced in the whole society.
But the following situations are not suitable for the use of emergency contraception-An Ting:
(1) has been identified as pregnant;
⑵ There are many unprotected sexual intercourse in one cycle.
14. What should I do if I miss the emergency contraception time?
You should go to the hospital or family planning clinic for examination as soon as possible. If you are pregnant, you can also go to the hospital for contraception in luteal phase or induce labor to terminate pregnancy.
Emergency contraceptive method
1, hormonal contraception [emergency contraception]
Must be taken within 72 hours after sexual intercourse. Take two tablets before leaving the hospital, 12 hours later. A few women will gradually disappear when 12 urinates. If you vomit 3 hours after taking the medicine, please contact the hospital as soon as possible. The next visit may be as usual, or it may be earlier or later. Please discuss with your doctor in detail the contraceptive methods to be adopted in the future, because emergency contraceptives are not suitable for routine use. If you have sexual intercourse between taking emergency contraceptives and the next menstrual period, you must use condoms or other barrier contraceptive methods to ensure safety.
2, intrauterine device contraception:
Intrauterine devices can be placed within 5 days after sexual intercourse. If you like, you can continue to use this method of contraception. The next menstruation comes as scheduled, but the amount of menstruation may be more and the menstrual time will be longer.
Precautions:
1. For your health and safety, if you are pregnant, please honestly cooperate with the doctor. Or if you suspect that you are pregnant, please tell me frankly. Emergency contraception may lead to a rare complication called ectopic pregnancy. Therefore, if you have a strong pain in your lower abdomen, please return to the hospital or see a doctor immediately. 3. If the menstrual period doesn't come or the menstrual amount is very small, please contact the hospital or consult a doctor as soon as possible, and have a pregnancy test if necessary, because the emergency contraceptive method will also fail and get pregnant. So, no matter which way you use, you must come back in three weeks.

Q: I would like to ask about the feasibility and steps of contraception after the event. What kind of pills should I take if possible? Thank you.
Dr. Lin replied: contraception afterwards is a remedy for not using contraception during sexual intercourse. This is the last resort. Usually take medicine within 24 hours after the event, but now there are drugs that can be extended to 72 hours after the event. In short, the sooner the better, and there is a risk of contraceptive failure. Drugs, such as No.53 contraceptive pill for visiting relatives, Yuting, etc. There are different types, and there is no systematic comparison.

Is there any emergency contraception? Great!
Emergency contraception is an emergency measure to prevent pregnancy after unprotected sex. The purpose is to prevent embryo implantation and contraception, which can reduce induced abortion. It is only used as an occasional remedy, not as a conventional contraceptive method.
In life, we will encounter such a situation: women miss taking oral contraceptives, or condoms slip or break during sexual intercourse, or do not take contraceptive measures, or are raped, which often leads women to be nervous and passively expect menstrual cramps. Emergency contraception can solve the problem for these women and avoid unwanted pregnancy. Conducive to protecting women's physical and mental health.
There are many methods of emergency contraception. Here are only some methods that have been proved to be effective and have relatively mild side effects: 1, mifepristone is a progesterone antagonist, which can affect the changes of endometrium and is not conducive to the implantation of pregnant eggs; Its usage is that within 72 hours after sexual intercourse, one-time oral administration of10mg, 25mg or 50mg can achieve emergency contraception. 2. Levonorgestrel 18 0.75 mg, repeated 12 hours after taking the medicine 1 time. 3, ethinylestradiol 0. 1 mg+ norethindrone 1mg, repeated 1 hour/time after taking the medicine. 3, ethinylestradiol 0. 1 mg+ norethindrone 1mg, repeated 1 hour/time after taking the medicine. What needs to be emphasized here is that it must be used within 72 hours after sexual intercourse (no matter how many times sexual intercourse, it must be within 72 hours). Later sexual intercourse still needs contraceptive measures, otherwise there is still the possibility of pregnancy.
In addition to medical emergency contraception, intrauterine devices can also be placed within 5 days after sexual intercourse to prevent fertilized eggs from implanting. This is suitable for women who need contraception for a long time in the future.
Emergency contraception is gradually developing in China. With the deepening of scientific research, the popularization of emergency contraception knowledge will play its unique role in reproductive health technical services.
"Emergency Contraception" Assistance Center
China's first "emergency contraception" assistance center was formally established in Chengdu yesterday. It is reported that the "emergency contraception" assistance center will not only provide telephone consultation services, but also take the most effective contraceptive protection measures for those who need contraception in the shortest time. For the convenience of the general public, the center has opened two hotlines: 626 5932 (from the first day of the first month to the seventh day of the first month and all legal holidays) and 6633230 (before and during the Spring Festival).
Director Wang of the outpatient department of Chengdu Family Planning Guidance Institute reminded that during the Spring Festival, everyone should first take effective contraceptive measures. The best way after contraceptive failure is: after the incident, the woman should contact Chengdu contraceptive emergency center within 7 1 hour (never more than 120 hours). Specifically, the center can provide reliable services within 72 hours; After 72 hours, the reliability will be greatly reduced; If it exceeds 120 hours, the hope is slim.
According to Director Wang, during the Spring Festival, there were millions of floating people in Chengdu, and the number of people returning to Chengdu to visit relatives and get together suddenly increased. According to past experience, every year before and after the Spring Festival, the Family Planning Association will usher in a peak of contraceptive remedies, and the number of patients will increase several times than usual, keeping the staff busy. It is very necessary that this special aid center came into being before the first Spring Festival in the new century.
Many American women don't use emergency contraception. China Health Network 2000/02/23 Sohu.
A report in the United States pointed out that about one in ten women did not need oral contraceptives after unprotected sex, so they turned to the national free emergency contraception hotline. But about 25% of these women did not take the medicine within the recommended 72 hours. The researchers stressed that it is very important for women to take emergency contraceptive measures in time. Every year, 50% of pregnancies in the United States are unplanned pregnancies, and half of these unplanned pregnancies are terminated by abortion. If women can take oral contraceptives within 72 hours of unprotected sex, the risk of pregnancy can be greatly reduced. The author suggests adopting the current French practice, that is, you can buy emergency contraceptives without a doctor's prescription, so that they can take emergency contraceptive measures more conveniently and in time.
Several Emergency Contraceptive Methods During Festivals Nanfang Daily □ Pan Zi 2000/02/23 Sohu
Emergency contraception refers to emergency remedial measures taken within a few days after unprotected sex or contraceptive measures fail, with the aim of preventing unintended pregnancy and reducing the rate of induced abortion.
The data show that the average birth control rate in China is about 75%, and the effective rate is only 50% ~ 60% because of the imperfect contraceptive methods. One of the reasons is the failure of contraceptive measures, such as IUD falling off, IUD pregnancy, condom rupture or slippage; Second, the user did not use it as required, such as miscalculating the safety period and missing the contraceptive pill. Therefore, even if birth control measures are taken, a considerable number of women may get pregnant unexpectedly.
During the Spring Festival, couples who are separated from each other will reunite, so the probability of unintended pregnancy will definitely increase. Here are some emergency contraception methods. Their contraceptive mechanism is mainly to interfere with sperm migration and capacitation, or to interfere with tubal motility, fertilization and luteal function. Or interfere with the development and function of endometrium and the implantation of fertilized eggs.
Diethylstilbestrol was given a large dose of estrogen within 24 hours after sexual intercourse, 50mg per day for 4-6 days; Or ethinylestradiol, 0.5-2mg per day for 5 days. The treatment is accompanied by side effects, such as nausea, vomiting, headache, dizziness, abdominal distension and menstrual disorder. , and it is forbidden for patients with ectopic pregnancy and history of thromboembolism related to estrogen.
Progesterone can change the chemical and physical properties of cervical mucus, inhibit sperm penetration or affect blastocyst implantation, and also change the normal secretion peaks of FSH and LH in pituitary before ovulation, thus inhibiting ovulation. Use 0.75 mg levonorgestrel (LNG, commercial product Mingyou Ting, Huiting) immediately after each sexual intercourse, and use 0.75 mg every 12 hours; Or domestic quick-acting visiting relatives tablets, taken orally twice a day, half a tablet each time.
Danazol can inhibit gonadotropin and progesterone, and has a direct effect on ovarian steroid hormone production. Use twice a day,/kloc-once every 0/2 hours, 400mg each time.
Mifepristone is a progesterone receptor blocker. Take mifepristone 25mg twice a day within 24h after sexual intercourse. Side effects include mild nausea, vomiting and other symptoms, and no special treatment is needed.
Copper IUD can be placed within 5 days after sexual intercourse to prevent fertilization. Intrauterine devices have no side effects, can be used for long-term contraception, and have a protective effect on life with the same cycle.
Western emergency contraception (1February 10, 1999,10: 12 am)
In Britain, the number of people who use emergency contraception afterwards is increasing. Emergency contraception includes two measures, one is to take two groups of four tablets each, and the other is to place a device in the uterus. The first group of drugs must be taken within 72 hours after unprotected sexual intercourse, and the second group of drugs should be taken 12 hours after taking the first group of drugs. Although this kind of emergency contraceptive, called "morning after taking medicine", contains low hormones, it may still cause nausea. So some doctors prescribe some anti-nausea drugs at the same time as this contraceptive. This contraceptive can prevent eggs from being fertilized. This medicine is suitable for most women, but not for women with thrombosis and migraine. Another emergency contraceptive method is to insert a roll, which can be effective within five days of unprotected sex. However, this measure must be implemented by professional medical clinics.
Unplanned pregnancy and emergency contraception
Unintended pregnancy seriously endangers the physical and mental health of women of childbearing age. According to the statistics of the World Health Organization (WHO), there are about 50 million cases of unwanted pregnancy induced abortion in the world every year, of which about 20 million cases are unsafe abortions, and about 80,000 women die of abortion, which can cause tens of thousands of women to be permanently disabled. In the United States, because of emergency contraception, 2 million cases of ectopic pregnancy and childbirth and 6.5438+0.0000 cases of induced abortion can be avoided every year. Finland said that with the popularization of emergency contraception knowledge among teenagers, the teenage pregnancy rate and induced abortion rate in China dropped significantly. At present, there are about100000 cases of induced abortion in China every year, of which about 50% are contraceptive measures or contraceptive errors that have not been noticed. If these women know and have access to emergency contraception services, it is estimated that 300 induced abortions can be reduced every year? 00,000 cases.
Emergency contraception refers to a contraceptive method used by women to prevent unintended pregnancy after unprotected sex or contraceptive failure (condom rupture or slippage, omission of taking conventional contraceptives, miscalculation of safety period, etc.). There are two methods of emergency contraception: one is to place an internal contraceptive device within 5 days after sexual intercourse. This method must be carried out in a hospital or clinic with certain medical conditions. This method is generally not suitable for pregnant women. The second is to take the emergency contraceptive An Ting. The medicine can be taken within 72 hours after unprotected sexual intercourse or contraceptive failure, which can effectively avoid pregnancy. An Ting is an emergency contraceptive approved by State Administration of Pharmaceutical Products, which is suitable for China's national conditions. The approval number is: National Medicine Zhunzi (1998)XF- 1573. You can buy it at the local drugstore and take it according to the instructions.
Zhang Fu's "Clever" Mistake
Wu Ting (Chief Pharmacist, Institute of National Family Planning Commission)
A newly married couple is temporarily not considering having children due to economic reasons. Who knows that one day during sex, there was an accident that the jujube condom slipped. The couple finally took the condom out of the woman's vagina, but how to get the semen flowing into the woman's vagina out? As a result, when the husband really came up with a "smart" method, he asked his wife to jump in place. He said that semen can be "sucked away" by gravity, which his wife thought was a good idea. So the husband and wife danced for two hours, and they were both exhausted. The wife is afraid that it is not safe enough, so she washes her vagina with water until she thinks it is safe. Who knows, I was pregnant that time. If they knew that emergency contraceptives (such as An Ting) were effective within 72 hours after sexual intercourse, they wouldn't do the absurd things mentioned above, and they wouldn't get pregnant unexpectedly. Emergency contraception refers to the "emergency" remedial measures taken to prevent unintended pregnancy after unprotected sex or contraceptive failure. It is inappropriate for some people to call the emergency contraceptive "the morning-after contraceptive" because it means taking it immediately after sexual intercourse. Some people think that emergency contraceptives are "morning contraceptives" or "morning contraceptives", but they are not exactly the same. Emergency contraceptives, such as An Ting, are effective within 72 hours after sexual intercourse. Of course, using it as soon as possible after sexual intercourse can avoid forgetting to take it or missing it. Experts suggest that families of women of childbearing age, especially newly married families, should always keep 1-2 boxes of emergency contraceptives (such as An Ting) to prevent unintended pregnancy.
Family medicine students, the second half of May 2000.
Conventional contraception and emergency contraception
Wu Ting (Chief Pharmacist, Institute of National Family Planning Commission)
A woman in her thirties told the doctor that her recent menstruation was either quiet for two or three months late or menacing. It lasted for more than ten days and a half, which affected her work and life. Finally, the doctor learned that she used the emergency contraceptive as a regular contraceptive. People can't help asking: Is emergency contraception safe?
Emergency contraception can only be used occasionally, and it cannot replace conventional contraception. For example, experts summed up An Ting and its possible side effects (1) nausea: the incidence of this kind of situation is very low, and it usually disappears in less than 24 hours. (2) Vomiting: Take it with food or before going to bed to relieve nausea or vomiting. If vomiting occurs within 2 hours after taking the medicine, you should take 1 tablet immediately. (4) Menstrual changes: Most women have menstrual cramps as scheduled, and some women have their menstruation earlier or later. If menstruation is delayed for a week, you should have a pregnancy test to see if contraception fails.
An Ting, an emergency contraceptive, is not suitable in the following situations: (1) It has been confirmed as pregnancy. The survey shows that some women continue to take emergency contraceptive measures without knowing that they are pregnant, but this has not increased the birth defects or other problems of babies. But in order to prevent other accidents, it has been confirmed as pregnancy, so it is best not to continue using An Ting. (2) There are many unprotected sexual intercourse in one cycle. (3) Women who smoke regularly.
If you miss the emergency contraception time, you should go to the hospital or family planning clinic for examination as soon as possible or take the method of inducing menstruation and terminating pregnancy under the guidance of a doctor. If you are diagnosed with pregnancy. You can also go to the hospital to take medicine or artificially terminate the pregnancy.
Emergency contraception, the failure rate is less than 2% Wu Ting (director pharmacist of the Institute of National Family Planning Commission)
A young woman walked up to the doctor and said, "Alas, I was cheated again. I have taken medicine this month. " It turns out that this woman has had five induced abortions in three years. When she heard that emergency contraception could solve the problem, she took enough medicine herself, but she didn't understand why she was pregnant again this time. Medical research believes that pregnancy begins after the fertilized egg is implanted into the endometrium. Once implanted, emergency contraception is ineffective, so emergency contraception must be used before pregnancy to prevent pregnancy. Taking emergency contraceptives (such as An Ting) can prevent most pregnancies. If the medication method is correct, the failure rate is less than 2%. Emergency contraception (such as An Ting) can only remedy the previous sexual intercourse, and it is impossible to have protection after taking the medicine.
