A must-read for women: Contraceptive secrets you don’t know

　　When it comes to birth control, doctors may not tell you everything, and some key facts are not common to most. female As far as I know, it has not attracted enough attention.

　　Do you think that doctors will tell you immediately if there are any new breakthroughs in contraceptive measures, right? Unfortunately, the doctor is probably hiding a lot of details from you. Why? Maybe because you didn't raise any questions, she thought you had mastered all the information she needed to know; maybe her schedule was full and she received countless eager people like you every day, so she had no time to have an in-depth conversation with you and was perfunctory.

　　A poll of more than 2,000 women was conducted, and 33% of women responded to the annual Gynecology The examining doctor just scratched the surface and dealt with it. It is precisely the information you do not understand that may lay hidden dangers and harm you. Among women who take contraceptive measures, 2/3 find themselves "unexpectedly" pregnant because the method they use is incorrect or does not fit well with their lifestyle. In actual practice, contraceptive methods cannot be 100% safe, nor can they prevent infection. sexually transmitted diseases , but the following 7 incompletely known facts are likely to have a serious impact on your life.

　　Secret 1: Weight plays a role

　　For women aged 18-39 who weigh 58 kg or more, oral contraceptive pills are 60% likely to fail, especially those with low estrogen levels. Women who are overweight have a faster metabolism and require more hormones to prevent conception. Moreover, birth control pills have a fat-dissolving effect and may "stay" in the places where fat is stored in the body, unable to reach the bloodstream where they should be to actually take effect. If you weigh more than 58 kilograms, it is best to ask your doctor to recommend other more reliable methods, such as intrauterine devices, or a combination of birth control pills and condoms to ensure that everything is foolproof.

　　Secret 2: What lasts is the most effective

　　In fact, there are many very effective contraceptive methods that you are not aware of, have never imagined, and are not recommended to you. Curious? The intrauterine device (IUD) is one example.

　　This is placement Uterus The small T-shaped contraceptive device inside is made of flexible soft plastic and must be inserted into your body by a doctor. After that, even if the egg has been fertilized, it will not implant and grow in the uterus. As long as there are no abnormalities, it can be left alone for one or two years. It will not cause trouble to sex, which is very convenient.

　　Generally speaking, today's IUDs are quite safe. Only one brand called "Dalkson Shield" once had deviations and "disappeared" from the market in the 1970s, but it still affected the reputation of IUDs to some extent. Although it is quite common in other countries, less than 1% of women choose to use it. This situation is not optimistic, because for monogamous families, although IUD cannot guarantee that you will not contract sexually transmitted diseases, it is indeed the most effective contraceptive method. Once inserted, you can forget about its existence. Not only does it have no hormonal side effects that other contraceptive pills may cause, but it is also extremely effective - with only a 1% failure rate per year.

　　There are two types of IUDs, the latest being Mirena. As we know, male More than 100 million ejaculated semen sperm , this mighty army scrambles to swim in the female reproductive tract, able to swim 2-3 millimeters per minute. After passing through the four major barriers of the vagina, cervix, uterine cavity and fallopian tube, it dates with the egg. The principle of Mirena is to release gestin into the uterus, which thickens the cervical mucus, making it difficult for sperm to penetrate the mucus and continue to ascend into the uterine cavity to meet the egg. It can stay in the human body for at least 5 years. Another type is Paracard, made of copper. The sperm army does not care about the long distance, and after a week of taking the contraceptive pill, it starts to take effect. It swings its tail forward, and the oncoming force can be described as menacing. Many sperm surround an egg, digest its peripheral zona pellucida, break through the cells surrounding the egg, dissolve the acid between the cells, and open the way for the next sperm. The entire process of combining the sperm with the egg cell is fertilization.

　　Paracard's strategy is to try to weaken the sperm's motility and protect the eggs from fertilization. It can be left in the body for at least 10 years. After removal, fertility returns to normal. If there is any flaw, it is that the uterus of women who have never given birth is not soft, and it is difficult to place it. There is occasional pain, but only in the first few months. Also, during menstruation, the pain in the lower abdomen and waist may be slightly more severe than before. If you have a regular sexual partner and the other person has no history of sexually transmitted diseases, IUD is undoubtedly the ideal choice. However, the best IUD, due to incorrect placement, or gynecological disease , will also fail. Women with a pelvic history are not advised to use an IUD as it may worsen bacterial infections.

　　Other unsuitable groups: those with extreme uterine retroflexion, endometritis, salpingitis, Vaginitis , uterine fibroids and other gynecological diseases; those with excessive menstrual flow and secretions.

　　Correct operation: Check with a doctor → Determine whether it is suitable → Choose a shape → Choose a time (a few days after menstruation, no more than a week at the latest) → Ask a doctor to operate → Check once a year.

　　Secret 3: The hidden dangers of condoms

　　Most condoms are made with spermicidal nonnoxynol-9, which is not only ineffective in preventing STIs, but may increase the risk of contracting AIDS and other sexually transmitted diseases. Its working principle is to achieve the purpose of contraception by destroying the membrane of sperm cells. In the process, the protective membrane on the edge of the vagina may also be destroyed. The U.S. Drug Administration believes that the risk of contracting sexually transmitted diseases when using condoms increases due to cell damage, and is considering putting a warning label on finished products that contain spermicidal ingredients.

　　Use it properly to avoid future troubles: pinch the small pocket at the top with your fingertips to remove the air inside. If there is air remaining, the top will bulge and may fall off midway. Put it on the erect genitals, open the curled part in circles, do not entangle the pubic hair, and do not have wrinkles. It’s better if you put it on from the beginning of intercourse. Pay attention to how you handle it after use. When pulling out, hold the root and pull it out slowly, otherwise it may fall off in the vagina. If you do not leave the body for a while after ejaculation, the male genitals will shrink and there is a risk of semen leaking out.

　　Secret 4: Strictly take medication time

　　The principle of oral contraceptives is to artificially create a pregnancy-like state by taking sex hormones and inhibit ovulation. If used correctly, it is a contraceptive product that can achieve excellent contraceptive effects. It is characterized by reliable effect and easy use.

　　However, because it contains estrogen, it should be examined and judged by a doctor before taking it. When you start taking it, you don't have to wait a whole month for the effects to start, and it doesn't have to start on a Sunday. Perhaps many people have heard that the most magical number is 7 days, but this is pure fiction! After taking the medicine for a week, you need to take some auxiliary measures (such as condoms).

　　Hormones are very effective in preventing ovulation. After that, you can be busy having fun without worrying about "fish slipping through the net". Of course, don't forget that the prerequisite is that neither you nor he has a history of sexually transmitted diseases. No matter what precautions are marked on the medicine package, you can start taking it on any day of the week. The key is to ensure that the number of days is correct and you do not miss a dose. The statement that it must start on Sunday is medically untenable. If there is such a statement, it is only to prevent women from not having their period on weekends. If you are already taking medication but want to adjust the start date, what is the safest way to do it? “"Relaxation pills" will cause menopause. Don't count on a Sunday to start another cycle. You can take them earlier, any day, if you want. Most of the reasons for its failure are forgetting to take it.

　　Remember: the effectiveness of a pill only lasts for 24 hours, and the effectiveness is 0 after 48 hours. If you forget, it is still safe within 36 hours. You should take one tablet immediately and continue to take it as prescribed in the future. If you forget to take it for more than two days, you can stop taking it and start again after the next menstruation. Possible side effects: Nausea during the taking period, because the body will react to the pregnancy state and disappear in 10-15 days; weight gain and abnormal bleeding may occur in the early stage. Long-term users should avoid immediate pregnancy, and it is better to wait at least 4 months apart.

　　Secret 5: More hormonal options

　　Nowadays, two new products are popular on the market: the contraceptive patch and the contraceptive ring, which are as effective as oral pills and even safer. There is no need to worry about keeping track of the day every day. The contraceptive patch is a sticky patch that is one inch long and half an inch wide. It is applied to the buttocks, abdomen, torso or upper arm for three weeks every month. It releases hormones that prevent ovulation into the body through the surface of the skin.

　　The contraceptive ring is a very flexible ring that contains hormones and is inserted into the vagina. It is left in place for three weeks and is removed after one week. Menstruation will begin as scheduled. Possible discomfort reactions: increased vaginal discharge, inflammation or pain. But as long as they are used properly, these two products can guarantee a 99% success rate.

　　Secret 6: The chance of pregnancy during contraception is higher than imagined

　　When doctors tell you how effective contraceptives are, it is based on the premise of "proper use", such as insisting on long-term use and ensuring that every step is correct every time. From a scientific point of view, the effectiveness of contraceptive pills is 99%, which means that within a year, only one out of every 100 users may have a defect, while the effectiveness of condoms is 97%. However, in practical applications, the true effectiveness of the two is 94% and 86% respectively. To ensure birth control pills are effective, they should be taken at the same time every day. It can help you remember the time better when combined with your daily routine, such as taking it every morning after brushing your teeth. If you forget to take it, read the precautions carefully to see what you can do to make up for it, so as not to waste all your efforts. If a woman who chooses a condom has less secretion, she can apply some lubricating ointment and use it together to fix it tightly to prevent slipping for better results.

　　Secret 7: Can ordinary contraceptive products be equated with famous brands?

　　Ordinary contraceptive products are at least 60% cheaper than name-brand products, making them more attractive. However, some experts believe that there is no evidence that the two are equally safe. So, does it mean that taking ordinary products is much more likely to lead to "unintended pregnancy"? No one is sure. In such a serious matter as contraception, no conjecture is allowed. Of course, experts do not object to you using ordinary products, but you should remember that this is different from a headache. If one medicine does not work, you can switch to another medicine. The risk of verification of birth control pills is too high. You will only know whether it works or not when something troublesome appears in your body.

　　You may have heard the following information before, but don’t act blindly until you understand it! It is still possible to get pregnant during menstruation. After sexual intercourse, sperm can still survive in the female body for 5 days. If ovulation occurs immediately after menopause, it is still possible to become pregnant during sexual intercourse during menstruation.

　　Extravaginal ejaculation has many risks.

　　It is very risky to withdraw the genitals when ejaculation is about to occur. This requires considerable skills. Firstly, if the withdrawal is slow, it will flow out. Secondly, during sexual intercourse, the male testicles may eject semen at the upper end of the vagina and the cervix at any time, which will inevitably not enter the cervical canal. It is especially dangerous for people who lack sexual experience or have premature ejaculation (special interview consultation) tendencies that cannot be well controlled. Moreover, interrupting sexual intercourse at the peak of sexual intercourse will affect the sexual pleasure of both parties, and repeated repetitions may cause "sexual deficiency syndrome". 19% of sexual partners who rely on this method of contraception may become pregnant within a year. Therefore, it can only be used when contraceptive tools are not available or in emergency situations. Condoms will expire. Many people often forget to check the expiration date when using condoms. Once they expire, they are particularly vulnerable to pregnancy or sexually transmitted diseases. The rubber material will naturally weaken once its effective time expires.

　　There is no doubt that the cost of an unintended pregnancy is much greater than spending more money to buy brand-name products, if financial resources are indeed limited.
