Eight secrets of safe contraception there is a limit on the number of times to use contraceptive.

Most condoms are made of spermicidal nonnoxynol-9, which is not only ineffective in preventing STD infections, but may increase the risk of HIV / AIDS and other sexually transmitted diseases.

Secret 1: hidden dangers of condoms

Most condoms are made of spermicidal nonnoxynol-9, which is not only ineffective in preventing STD infections, but may increase the risk of HIV / AIDS and other sexually transmitted diseases. Its working principle is to achieve the purpose of contraception by destroying the sperm cell membrane, and in the process, the protective membrane at the edge of the vagina may also be destroyed. The US Drug Administration believes that there is an increased risk of contracting STDs with condoms due to cell damage, and is considering putting warning labels on finished products that contain spermicidal ingredients.

Use it properly to avoid future trouble: the fingertip pinches the small pocket at the top to remove the air inside. If there is air residue, the top bulges and may fall off midway. Put it on the erectile genitals and open the curly parts one by one. Don't get involved in pubic hair or wrinkles. It's better to wear it from the beginning of sexual intercourse. Pay attention to the treatment after use, press and hold the root to pull out slowly, otherwise it may fall off in the vagina. If you do not leave the body temporarily after ejaculation, the male genitals will shrink and there is a risk of semen outflow.

Secret 2: weight is at work

For women between the age of 39 who weigh 58kg or more, oral contraceptive is 60 per cent likely to fail, especially those with low estrogen levels. Overweight women have a faster metabolism and need more hormones to prevent pregnancy.

Moreover, contraceptive has the effect of dissolving fat and may "stay" in the place where fat is stored in the body, unable to reach the place where it should be in the blood. If you weigh more than 58 kilograms, it's best to ask your doctor to recommend other more reliable methods, such as an intrauterine device, or a combination of contraceptive and condoms to be foolproof.

Secret 3: the enduring is the most effective

In fact, there are quite a lot of effective contraceptive methods that you don't know about, have never imagined, and have never been recommended to you. Curious? Intrauterine device (IUD) is one of the cases. This is a small T-shaped contraceptive device placed in the womb. It is made of flexible soft plastic and must be embedded in your body with the help of a doctor. After that, even if the egg has been fertilized, it will not grow in bed in the womb, as long as there is nothing abnormal, no matter for a year or two, and will not cause trouble to sex, very convenient.

Generally speaking, today's IUD is quite safe, only one brand called "Dalkson Shield" once deviated and disappeared from the market in the 1970s, but it more or less affected the reputation of IUD. Although it is already quite common in other countries, less than 1% of women choose to use it. This situation is not optimistic, because for monogamous families, IUD does not guarantee you against sexually transmitted diseases, but it is the most effective form of contraception. Once placed, you can forget about it, not only without the other hormonal side effects that contraceptive may have, but also with excellent results-with a failure rate of only 1 per cent a year.

There are two types of IUD, the latest of which is Mirena. As we know, there are more than 100 million sperm in the semen emitted by men, and this vast army swims in the female reproductive tract, swimming 2-3 millimeters per minute, breaking through the vagina, cervix, uterine cavity and fallopian tubes. Date with eggs. The principle of Mirena is to release pregnancy hormone into the uterus, thickening the cervical mucus, making it difficult for the sperm to penetrate the mucus and unable to move upward into the uterine cavity to meet the egg. It can be placed in the human body for at least 5 years. The other is Paracard, made of copper.

The sperm army did not hesitate to travel a long way, and after a week of clinging to the drug, contraception began to wiggle its tail forward with a menacing trend. Many sperm surround an egg, digest its peripheral zona pellucida, break through the cells around the egg, dissolve the acid between the cells, and open the way for the next sperm, the whole process of sperm combining with the egg is fertilized.

Paracard's strategy is to try to weaken sperm motility and protect eggs from fertilization. It can be placed in the body for at least 10 years, and after it is removed, the fertility returns to normal. If there is a flaw, it is that the unborn womb is not soft, difficult to place, and occasionally painful, but only for the first few months. Also, during menstruation, the pain in the lower abdomen and waist may be slightly more severe than in the past. If there is a fixed sexual partner, the other party does not have a history of STDs, IUD is undoubtedly the ideal choice. However, the best IUD can also fail because of incorrect placement or gynecological diseases. Women with a history of pelvic disease do not recommend the use of IUD, which may worsen bacterial infections.

Other unsuitable people: those with gynecological diseases such as extreme retroflexion of uterus, endometritis, salpingitis, vaginitis, hysteromyoma, and excessive menstruation and secretions.

Correct operation: check the → by the doctor to determine whether it is suitable for → to choose the shape → selection time (a few days after menstruation, no more than one week at the latest) → ask the doctor to operate → once a year.

Secret 4: strict medication time

The principle of oral contraceptive is to artificially create a pregnancy-like state by taking sex hormones to inhibit ovulation. If used correctly, it is an excellent way to get contraception.

Most of the reasons for its failure are due to forgetting to take it.

If you forget, it is safe to take one tablet within 36 hours, and then take it according to the regulations. If you forget for more than two days, you can stop and start again after your next menstruation.

For long-term users rabbit vibrator , immediate pregnancy should be avoided and it is better to have an interval of at least 4 months.

Ordinary contraceptives are at least 60% cheaper than famous brands, so they are more attractive. However, some experts believe that there is no evidence that the two effects are equally safe. So, is it that taking ordinary products is much more likely to lead to an "unintended pregnancy"? No one is sure.

Any conjecture is not allowed for such a serious thing as contraception. Of course, experts do not object to your use of ordinary products, but you should keep in mind that this is different from a headache, taking one medicine does not work, you can also change another medicine. The verification of contraceptive is so risky that you don't know if it will work until there is an extra troublesome "thing" in your body.

It is inevitable not to enter the cervical canal. It is especially dangerous for people who lack sexual experience or have a tendency to have premature ejaculation that cannot be well controlled.

Moreover, interruption of sexual intercourse in the best part of sexual intercourse affects both parties' sexual pleasure, and repeated repetition may lead to "sexual deficiency." Nineteen percent of sexual partners who rely on this method of contraception are likely to become pregnant within a year.

Therefore, it can only be used when there is no contraceptive, or at an extraordinary moment. Condoms will fail many people often forget to check the expiration date when using condoms. Once they expire, they are particularly likely to get pregnant or become infected with sexually transmitted diseases. The rubber material will naturally weaken after the effective time.

Secret 6: can ordinary contraceptive products be equated with famous brands?

Secret 7: more hormonal choices

Nowadays, two new products are popular on the market: contraceptive patches and birth control rings, which are as effective or even safer as oral pills, without having to worry about remembering the days every day. A contraceptive patch is a sticky paste one inch long and half an inch wide. It is applied to the buttocks, abdomen, body or upper arm for three weeks a month. It releases hormones that prevent ovulation into the body through the surface of the skin. Birth control ring is a very flexible ring, containing hormones, embedded in the vagina, placed for three weeks, take off a week, menstruation will arrive as scheduled.

When the doctor tells you how effective contraceptives are, it is based on the premise of "proper use", such as sticking to long-term use and ensuring that every step is correct at all times. Scientifically, contraceptive is 99 per cent effective, which means only one in 100 drug users is likely to go wrong in a year, and condoms are 97 per cent effective.

However, in practical applications, the real efficiency of the two is 94% and 86%, respectively. To ensure that contraceptive is effective, you should take it at the same time every day. When combined with daily life, it can help you remember the time better, such as taking it after brushing your teeth every morning.

If you have amenorrhea for 3 months in a row, you should suspend medication, take other contraceptive measures, and continue to take medicine after menstruation recovers itself. If there is still no menstruation within 1 month after withdrawal, the doctor should be asked to use medroxyprogesterone, compound progesterone or menstrual tablets according to the examination, and then switch to other contraceptive.
