Editor’s Note: September 26 is World Contraceptive Day every year. According to statistics, about 30% of women have had at least one abortion. That is to say, 3 out of 10 women have had an abortion in their lifetime, which is not a small proportion. What is the correct contraceptive method? Which of the popular contraceptive methods are unreliable? See what the obstetrician and gynecologist said. Note: The picture is Zhang Facai’s work.
As long as women have sex, We have to face two choices: Pregnancy and contraception. No matter which method of contraception, The success rate of contraception is not 100%, Even the most successful ligation, There is also the possibility of natural recanalization. This leads to contraceptive failure. All contraceptive methods have their advantages and disadvantages. Therefore, no method can have an absolute advantage. If anyone can invent a contraceptive method with a success rate of 100% and no what damage to human body, Then there is no doubt that, He will definitely win the Nobel Prize. It is precisely because any contraceptive method has the probability of failure. So whichever way you choose, As long as there is sex, Then there is the possibility of pregnancy, Only then can the remedy of abortion be used. Although contraceptive methods are likely to fail, However, there are also reliable and unreliable methods. There are many so-called contraceptive methods, just like some dirty martial arts moves, which are of little use and spread widely. Choose a few simple ones to talk about. Again, the following methods are strongly not recommended and must not be imitated.
Safety Period
The so-called safe period is the non-ovulation period. Ovulation is regulated, There are periodic rules to follow, Generally, ovulation occurs 14 days before menstruation, If it weren’t for having sex during ovulation, It seems that you shouldn’t be pregnant. But this idea is too naive, Ovarian regulation is not like Jiuquan Satellite Launch Center’s control of rocket launch, Every minute is not bad, Who knows hypothalamus, pituitary what when happy, Send a message to the ovaries, Ovulation is premature or delayed, They won’t inform you. Besides, After the eggs are discharged, Not that it will be absorbed immediately, There will be waiting times, And the sperm doesn’t run out right away, You’ll be waiting, too. In such a third class and a second class, Maybe both sides will wait, you this contraception even failed. And for those menstrual cycle irregular people, let alone what safety period. So, safety period is not safe, in the eyes of obstetricians and gynecologists, if you say contraceptive method is safety period contraception, it is basically equal to not contraceptive. Safety period does not cheat father, it pits mother! Contraceptive Failure Index: Errors Index: Pit Niang Index:
Emergency contraceptive pill
It is also a contraceptive pill, you can see clearly, it is quite different from oral short-acting contraceptives. The oral short-acting contraceptives mentioned earlier are taken orally one pill every day for 21 consecutive days as a cycle. Common contraceptives on the market, such as Marvelon, Minding, Daying-35 and Yousiming; The emergency contraception pill is after sex, For disposable use, Common on the market such as Yuting, Anting and Mifepristone. Oral emergency contraception is only suitable for conventional contraceptive failure (such as condom falling off). Or unwanted unprotected sex (such as rape), and not suitable for conventional contraception. This method not only has a high rate of contraceptive failure, but also has obvious side effects due to the large dose of emergency contraceptives, which is also relatively large in adverse effects on menstruation and can often cause menstrual disorders for several consecutive months.

Ejaculation in vitro
This is not much to say, do you think contraception can be achieved without being shot into the vagina? You just didn’t see the sperm go in. You underestimated the ability of sperm to swim too much. In the eyes of doctors, coitus interruptus is about equal to no contraception.

If pregnancy is regarded as an imaginary enemy, then the conventional contraceptive martial arts are different from school to school. Here are the reliable contraceptive methods of several famous schools.
Ligation
It belongs to Fuwei Escort Agency, which is one of the contraceptive methods. Lin Yuantu created a set of [sword method to ward off evil]. Mighty Wulin. It can be said that With this set of sword moves to ward off evil spirits, It can sweep almost all enemies-that is to say, this is the martial arts with the highest victory rate. However, I think everyone knows the preconditions for practicing this skill, You need to do some damage to your body. The method of ligation is to cut off the fallopian tube. It is the long corridor connecting the two sides of the palace of the uterus mentioned earlier. The function of these two long corridors is very important. Is the only way to transport fertilized eggs, If you cut it off, Then the fertilized egg will not be able to enter the palace. You can’t implant, Naturally, you won’t be pregnant. However, although you are strong in martial arts, But it is difficult to practice, You have to go to the hospital specially for an operation. Besides, The price to be paid is not small, That is, it is easier to cut off than to recanalize. It is very pleasant to make a clean break when ligating. However, in case you regret and want to be pregnant again, then you have to take back the two fallopian tubes that have been disconnected, and the operation will be much more troublesome. Therefore, those who choose this sect are basically women who have already given birth, and they no longer intend to give birth. The only requirement is to use enough superb moves to solve their opponents.

Intrauterine device
Belonging to the contraceptive method of Thunderbolt Hall. Although Thunderbolt Hall has a good reputation, But it is not martial arts that win, But by making powerful explosives and firearms. IUD acts similarly, Is to place an IUD in the uterus, Thereby interfering with implantation, The contraceptive effect is also ideal. And compared with the poor reversibility of ligation, IUD is much more reversible, After taking it out, the reproductive function can be restored soon. And the surgical procedures for placement and removal are very convenient. Of course, Since it’s [explosive firearms], Then the risk of self-injury is not small. For example, There may be risks of bleeding, infection, uterine perforation during placement, But the probability is very low, It is mainly some problems after placement. There are a few people who will suffer from waist soreness, abdominal pain, abnormal menstruation and other discomfort manifestations after placing intrauterine devices. Even some people will be pregnant after placing the IUD, but also ectopic pregnancy. What’s more, some people’s IUD may gradually fuse with the uterine wall and grow into the myometrium, which is medically called IUD incarceration, bringing great trouble to the removal.

Short-acting oral contraceptives
Belonging to the Beggars’ Sect in contraceptive methods. The town sect of the Beggars’ Sect has 18 magic skills to subdue the It is famous for its vigorous internal force. The oral short-acting contraceptive pill is also made by estrogen and progesterone. Regulate the body’s endocrine, Inhibit ovulation, It also belongs to the cultivation of internal skills. Moreover, There are many misunderstandings about the Beggars’ Sect in Jianghu, People are full of disdain for beggars, Lack of respect, In fact, the Beggars’ Sect disciples have strict discipline, Once upon a time, He is loyal and full of sense of justice. Although it cannot be ruled out that some disciples have misbehaved, But in general, Beggars’ Sect is also a big positive gang in Jianghu. Similarly, Oral short-acting contraceptives have also been treated unfairly in what. As mentioned earlier, the Chinese people are surprisingly afraid of the word “hormone”. As long as what’s things are stained with the edge of “hormone”, it is basically to be strictly guarded against. I just want to avoid pregnancy. Why should I take hormone? In fact, oral short-acting contraceptives are far from so terrible. On the contrary, because of its deep internal skills, So the contraceptive effect is excellent. In addition, It has a number of other added benefits, As mentioned earlier, it can relieve dysmenorrhea, Regulate the menstrual cycle, It can also reduce the incidence of ovarian cancer and endometrial cancer, Therefore, many clinical treatments for irregular menstruation also use oral short-acting contraceptives. Of course, It also has certain side effects, Such as the risk of thrombosis, But we yellow people have a lower risk of thrombosis than white people. If you only eat for a year and a half, Can regular physical examination, or very safe. However, it does have a shortcoming, is the application of more troublesome, a cycle of 21 days, you need to insist on taking medicine on time every day, if missed will seriously affect the contraceptive effect. However, just like brushing teeth, although also every day to insist on doing, as long as the formation of habits, also don’t feel troublesome.

Condom
It belongs to the ancient tomb school in contraceptive methods. It has a long history, but since Wang Zhongyang lived in seclusion in the ancient tomb, the people in the ancient tomb have a characteristic: they will never come out! After Lin Chaoying received his disciples, he also made people swear that they would never leave the tomb. The same is true for condoms, and sperm is resolutely not allowed to come out! Sperm is isolated, Can’t meet the egg, The effect of contraception has been achieved. I believe most people who have a little knowledge of contraception, The understanding also stays at the condom level, However, with contraceptive awareness, It is also good to know how to use condoms. And condoms also have some additional benefits. The most important is the prevention of sexually transmitted diseases, Because the incidence of cervical cancer is mostly related to HPV infection, which can also be transmitted through sexual transmission, so the use of condoms can also reduce the incidence of cervical cancer. However, it should be emphasized that condoms are among the four contraceptive methods introduced here, with the lowest success rate of contraception, which is closely related to the correctness of the use method.
