There are seven lies in female contraception. There are five folk methods of contraception.

Learning how to use contraception is the most important lesson for adult men and women. However, many people have little knowledge of how to use contraception correctly and scientifically. Mistakes in contraceptive methods are likely to cause inevitable regrets and affect people's health.

There are seven lies about female contraception

Lie one

You won't get pregnant during the safe period.

Many women with more accurate menstrual cycles can calculate their own safety period. Each menstrual cycle of women is divided into menstrual period, ovulation period and safe period. Generally speaking, there is no egg exclusion during the safe period, so there is no need to worry about the problem of sperm entering the body to make the egg pregnant.

But you may not know that sperm can fertilize an egg within three days after excretion, but there are also reports that sperm retain the ability to fertilize a week after sex. Although the ovulation period is in the middle of menstruation adult shop , it may advance or postpone ovulation due to the influence of external environment, temperature, mood, health status and other factors.

Therefore, the method of safe period contraception is not reliable at all. Generally speaking, the method of safe period contraception is only applicable to couples who have regular menstrual cycle, long-term cohabitation, regular life, mutual cooperation and understanding.

Lie two

Don't be afraid of the trouble to keep taking contraceptive.

What kind of contraception are you using? Contraceptive, which you must take before sex, does not guarantee the safety of "whim" sex. Are these short-term contraceptive measures boring you already?

In fact, in addition to external condoms, oral contraceptive, built-in contraceptive rings, there are many quite effective contraceptive methods you do not know. For example, an intrauterine device that must be surgically implanted into the womb. All it has to do is to prevent fertilized eggs from growing in the womb.

Generally speaking, as long as there is nothing unusual, it won't cause trouble for sex for a year or two. Intrauterine contraception does not guarantee you against sexually transmitted diseases, but it is one of the most effective methods of contraception. Once placed, you can forget about it, and there is only a 1% failure rate.

This long-term method of contraception is undoubtedly the most effective and convenient. But it is also not suitable for people, such as extreme retroflexion of uterus, endometritis, salpingitis, vaginitis, uterine fibroids and other gynecological diseases or excessive menstruation and secretions. If you are interested in intrauterine contraception, you might as well ask an experienced doctor in a regular hospital.

Lie three

The contraceptive effect of contraceptive is the same for everyone

The packaging of contraceptive, which is sold on the market, shows only a few types that are not suitable for people. So is it suitable for people to take, the effect is the same?

In fact, overweight women have a faster metabolism and need more hormones to prevent pregnancy. When they are in contraception, they will be hindered by too much fat in the body, which will greatly reduce the effect of drugs, and it is difficult to get rid of the influence of weight when "creating a baby". Therefore, they should be cautious when choosing appropriate methods of contraception and "making a baby".

Moreover, a lot of contraceptive has the effect of dissolving fat and may be stuck in the place where fat accumulates in the body, so it can't really play a role in the blood where it should be.

I would like to remind you that if you weigh more than 58 kilograms, it is best to ask your doctor to recommend other more reliable methods, such as an intrauterine device, or a combination of contraceptive and condoms.

Lie four

The effect of contraception is foolproof.

Do you think it is foolproof to use contraception? You must know that when the doctor tells you how effective contraceptives are, it is also based on the premise of proper use. Although contraceptive and condoms boast 99% and 97% efficiency. But in fact, in practical application, the real efficiency of the two is 94% and 86% respectively. That is to say, it does not have a 100% effective contraceptive effect at all.

To ensure that contraceptive is effective, you should take it at the same time every day. If you don't try to combine it with your daily life, it can help you remember the time better, such as after brushing your teeth every morning.

In case you forget to take it, read the notes carefully and see what you can do to make up for it. If the women who choose condoms have less secretion, they can apply some lubricating ointment to fix it tightly to prevent it from slipping, and the effect is better.

Lie five

If the penis is not fully inserted, that is to say, the man ejaculates in the woman's vulva instead of in the vagina, the woman will not get pregnant.

The fact is that it is possible for sperm to enter the vagina and continue to move toward the uterus.

How much do you know about the real principle of contraception?

The so-called principle of contraception is to use scientific methods to prevent and destroy some links in the normal pregnancy process, in order to avoid pregnancy and prevent childbearing. At present, there are many contraceptive methods, which can be summarized into the following methods according to their contraceptive principles:

(1) inhibition of ovarian ovulation

There are female short-acting and long-acting contraceptive and subcutaneous implanted contraceptives which can inhibit ovarian ovulation. The development and maturation of oocytes are affected by the hypothalamus and pituitary. This kind of contraceptive can inhibit the function of hypothalamus and pituitary to prevent egg development, thus achieving the purpose of contraception. In addition, women in lactation also have the role of inhibiting ovarian ovulation, so lactation can also be contraceptive.

(2) inhibit the normal development of sperm.

Gossypol extracted from cottonseed can inhibit the normal development of spermatozoa. Long-term use of gossypol can significantly reduce or completely disappear the number of sperm, thus achieving the purpose of infertility. This kind of men's contraceptive has not yet been widely used. In recent years, some physical methods (such as ultrasound, microwave, warm stimulation of testis) have been used to inhibit the spermatogenic function of testis, and some progress has been made.

(3) prevent sperm from combining with egg.

There are many methods of this kind of contraception, and its purpose is to prevent sperm from combining with eggs in order to achieve the purpose of contraception. For example, condoms, vaginal diaphragm, etc., so that sperm can not enter the vagina, or sperm that enter the vagina can not enter the uterine cavity; contraceptive has a strong spermicidal effect, put it into the vagina can kill sperm, so that sperm can not enter the uterine cavity; male and female sterilization can prevent sperm excretion or prevent sperm from combining with eggs, is a permanent contraceptive measure In the process of sexual intercourse, the use of in vitro semen or perineal urethral pressure method, so that semen outside the vagina or retrograde injection into their own bladder, so that semen does not enter the vagina.

(4) prevent fertilized eggs from implantation.

The uterus is the place where the fetus is conceived. If you try to interfere with the internal environment of the uterus, it is not conducive to the growth and development of the fertilized egg. The placement of a birth control ring in the uterus and various contraceptive visits can change the endometrium and prevent the implantation and development of fertilized eggs.

(5) staggered ovulation period of contraception

Staggered ovulation contraception is contraception in the safe period, that is, the use of menstrual cycle calculation, basic body temperature measurement and cervical mucus observation to grasp the ovulation period of women and avoid sexual intercourse during ovulation to avoid contraception, so that sperm and eggs miss the opportunity to meet.

Contraceptive methods commonly used by men

At present adult toys , although there are many contraceptive methods that can be used by people, there are few contraceptive methods for men, such as condoms, vasectomy or blockage, oral contraceptive, in vitro ejaculation and perineal urethral compression.

Condom is a kind of male contraceptive which is widely used at present, as long as it is used correctly, the contraceptive effect is better, but some people are afraid of affecting sex appeal or are not used to it, so they are not willing to use it.

Vasectomy or blockage is a sterilization operation, which is suitable for husbands who are infertile or whose wives are infertile.

Although oral contraceptive for men has been successfully studied, it has some shortcomings and can not be widely used at present.

The method of extracorporeal ejaculation and perineal urethral compression is not easy to grasp normally, so the effect of contraception is not reliable, and now few people use it.

Contraceptive methods commonly used by women

There are many contraceptive methods for women, such as contraceptives, birth control ring, tubal ligation or blockage, vaginal diaphragm, vaginal contraceptive ring, safe period and lactation contraception.

There are many kinds of contraceptive, including short-acting contraceptive, long-acting contraceptive, visiting contraceptive, subcutaneous implanted contraceptive, topical contraceptive and so on. Among them, contraceptive is the most widely used. If taken correctly, the contraceptive effect is almost 100%. Long-acting contraceptive is only used once a month, and some can be used once every 2-3 months; it can reduce the trouble of taking medicine every day, and the contraceptive effect is slightly inferior to that of short-acting contraceptive. Subcutaneous implantation of contraceptive can be used for contraception for about 5 years, but it can not be widely used because it has not been produced in China and is imported at present. Contraceptive for visiting relatives is quick-acting contraceptive, which is mainly suitable for visiting couples as well as newlyweds. The main function of contraceptive for external use is to kill spermatozoa, in which the effect of contraceptive film is the best, while that of contraceptive ointment is poor.

Birth control ring is the most widely used long-term contraceptive tool at present. Stainless steel circular ring is commonly used, this kind of birth control ring can be used for contraception for about 20 years at a time, but the disadvantage is that the dropping rate and pregnancy rate with ring are high. The contraceptive effect of birth control ring with copper is better, and the drop-off rate and pregnancy rate are lower, so it has been widely used in various places.

The method of vaginal contraceptive ring is simple, and the contraceptive effect is good bluetooth vibrator , and it has been widely used in some areas.

The use of vaginal diaphragm is more troublesome, if you can not correctly grasp the placement technology, it is easy to lead to failure, so it can not be widely used.

Tubal sterilization is a permanent method of contraception, which can be used for life-long contraception, especially for women who no longer have children or are unable to give birth due to illness.

The contraceptive methods of safe period and lactation period are not easy to master correctly. It is easy to lead to failure, so it is not suitable for promotion and use.

How to ensure that contraception does not fail

China's Marriage Law stipulates that the age of marriage for women is 22 years old, and women still have a childbearing period of more than 20 years after marriage. At present, it is advocated that a couple should have only one child, so women need to adhere to contraception for most of the whole childbearing period. Otherwise, it will lead to failure. So, how can we ensure that contraception does not fail?

First of all, the couple must realize the importance of family planning, should attach great importance to contraception, at any time (such as lactation) can not exist fluke psychology.

Contraception is a matter for both husband and wife, especially the husband should be more concerned about, care for and considerate to his wife, and should not put the matter of contraception entirely on the woman. For the sake of the wife's health, the husband should bear more responsibilities, not just for temporary convenience, resulting in the failure of contraception and bringing unnecessary pain to the wife.

At present, there are many contraceptive methods, each of which has its own characteristics. when choosing contraceptive methods, we should not only consider the convenience, but also take into account the effect, but also according to the individual situation, especially the woman's health and the characteristics of different periods, correctly choose feasible and effective contraceptive methods that are suitable for you. Some contraceptive methods, such as safe period contraception, lactation contraception and extracorporeal sperm excretion contraception, should not be used as far as possible because the contraceptive effect is not reliable.

To learn to correctly use condoms, vaginal diaphragm and other external contraceptive tools, otherwise it will lead to failure. In case of failure in the use of external contraceptives (such as condom rupture), remedial measures should be taken in time to prevent pregnancy.

In short, contraception is a long-term and arduous task, and we should not be careless at any time.

The most unbelievable folk five contraceptive methods that women should pay attention to.

Lactation contraception

Women who are not breastfeeding usually resume ovulation and return to menstruation 6 weeks after giving birth. And most breast-feeding women do not menstruation. Some people think that breast-feeding women do not menstruation, do not ovulate, and will not be pregnant. In fact, this understanding is wrong. Breast-feeding pregnant women may resume ovulation even if they do not have menstruation. If there is no contraception during this period, it is very easy to cause the woman to "conceive". Therefore, breast-feeding pregnant women should also have contraception.

Urination contraception

Some people think that after having sex with a man and a woman, letting the woman rinse her vagina with the method of urinating can be used for contraception. This is a kind of confused understanding. A woman's vagina and urethra are two different organs. After having sex with a man and a woman, it is impossible for the woman to flush the sperm from another channel out of the body by urinating.

"safe period" contraception

The so-called "safe period" refers to 7 days before menstruation and the first 8 days after menstruation. People also call it "the first seven and the second eight". This is not the period of ovulation for women. At this time, couples sleep together, generally will not make the woman pregnant, so people call this period of time "safe period". But the "safe period" is not absolutely safe. Because some women ovulate irregularly. Even if some women ovulate regularly, when their mood, living environment and physical conditions change greatly, their ovulation will lose the original rule. Therefore, it is not safe to use female safe period contraception.

Vaginal flushing method for contraception

Some people think that after having sex with men and women, if the woman carries out vaginal flushing, it can be used for contraception. This method is actually very unsafe. In the same room penis sucking , if the man ejaculates, countless sperm will quickly swim to the woman's uterine cavity. At this point, no matter how the woman rinses the vagina, she can't flush all the sperm out of the body. Therefore, with vaginal washing method of contraception, the woman can still get pregnant.
