The Most Unreliable Contraceptive Method in Sexual Life: Will Breastfeeding and Cohabitation Lead to Pregnancy

I believe there are various contraceptive methods, and everyone's choices are different. So far, the most commonly used contraceptive methods are condoms, contraceptives, etc. However, many contraceptive methods also have many unreliable methods. Did you go in? Next, let's take a look at the most unreliable contraceptive methods in sexual life

1. Room bounce

Past contraception guidelines have taught people that women can jump out of bed immediately after work to avoid the embarrassment of unintended pregnancy, thinking they can throw out semen. The ancestor of this invention is the Hippocratic master, the ancestor of Western medicine. There is also a legend in China that palace contraception is quite cruel in the movie "The Secret Life of Cixi". Later, eunuchs used wooden pestles to drive their waists crazy, brushed them with brushes, and washed them away with water, thinking that they could clean all their semen.

Analysis: These ideas are obviously childish. Firstly, the average male ejaculates about 40 million people each time, with small sperm size, each with a head size of 4-6 microns and a long tail size of 60 microns. Isn't it possible to jump up and throw it clean?

So, after unprotected sexual intercourse, jumping up and down or any other form of physical activity by women cannot reduce their chances of pregnancy. Whether the woman is standing or lying during ejaculation, the sperm will reach the entrance of the uterus - the cervix - within 90 seconds of ejaculation.

2. If you don't ejaculate, you won't get pregnant

Many couples try to play vaginal opening games because they want to get intimate and are afraid of getting pregnant. I was intimate with my boyfriend, only rubbing his genitalia, but he still couldn't help but ejaculate at the vaginal opening. Afterwards, I went to clean the genitalia, and since it was during ovulation, I don't know if she would get pregnant. "On the internet, many girls have this question, and they even think that as long as the penis is not fully inserted, it means that the man ejaculates in the woman's genitalia instead of inside the vagina, and the woman will not get pregnant.

Analysis: Generally speaking, it is not possible. The average length of the vagina is 7.5 centimeters. Sperm swims from the vaginal opening to the cervical opening, which can be described as a long journey. However, don't be too happy too early. There have been reports that this condition can also lead to pregnancy. Although the probability is extremely low, it cannot be ruled out that strong sperm have the endurance and courage to overcome difficulties and reach the cervix, enter the uterus, and combine with the egg.

3. Contraceptive pills can cause weight gain

When it comes to taking birth control pills, many women start shaking their heads and are usually unwilling to accept this method of contraception. According to the survey of married women in five cities in China in 2002, five contraceptive methods currently used in China are intrauterine device (IUD), condom, contraception, safety period and oral contraceptives, with the use rate of 41.17%, 4.79%, 3.18%, 0.88% and 0.77% respectively. The reason why people don't want to take pills is that many people believe that birth control pills have side effects, especially when taking them can lead to weight gain

Analysis: Generally speaking, oral contraceptives are often used for contraception, and there is also a possibility of treating menstrual disorders. Sometimes doctors also use them for the treatment of dysmenorrhea, functional uterine bleeding, endometriosis, endocrine system diseases, etc. We advocate for women to use scientific and reliable contraceptive methods. Modern short acting oral contraceptives have been proven to be highly reliable, safe, and have low side effects, with a usage rate of up to 30% -50% in Western countries.

4. Hymen can be used for contraception

Among many young couples, many believe that as long as a woman is a virgin and does not break this membrane during sexual activity, even if injected into the body, this membrane can prevent semen from entering the vagina, and women will definitely not become pregnant.

Analysis: There is a folk saying that the female hymen is complete, and men and women are pregnant without substantive sexual intercourse. This is rare in gynecological clinical practice, but it is not impossible. This is because the hymen of normal women has a small hole, otherwise the menstruation will flow out? Therefore, even if the semen is on the hymen, the sperm can enter the vagina through this hole, so it is wrong to think that hymen has the function of preventing semen, and it is incorrect not to be pregnant for the first time.

5. The top seven and back eight are the safest

After there is a saying of a safe period, men do not want to wear condoms and use the safe period for contraception. Are you in a safe period? "Many men in bed ask women if they are in a safe period when they don't want to wear condoms. In fact, the safety period is not as safe as people imagine.

Analysis: Women of reproductive age ovulate during their monthly menstrual cycle, with ovulation occurring 12-16 days before their next menstrual cycle, with an average of 14 days. The survival time of sperm is 3-5 days, and the survival time of eggs is 1 day. The danger period is 5 days before ovulation and 4 days after ovulation, while other times are the safety period. Ovulation has this pattern, but the actual ovulation date is still difficult to calculate.

Scholars in the United States have found that even women with a regular 28 day menstrual cycle may not have a certain ovulation period, with only 30% of the population being relatively fixed. Therefore, using calculation methods to determine the safe period is not safe. Irregular menstrual cycles, as well as changes in mental and environmental conditions, can alter ovulation dates. According to statistics, the failure rate of safe period contraception is as high as 14.4% -47%.

6. Lactation period=safe period

Having a child, breastfeeding, and not menstruating, women do not ovulate, so they will not get pregnant. Couples with this idea often suffer from the consequences. Because women who become pregnant four months after giving birth are very troublesome for the mother, not only affecting breastfeeding, but also facing consequences such as abortion.

Analysis: After delivery, the baby's inhalation of nipples can reflect and suppress the mother's hypothalamus, inhibiting ovarian ovulation. However, this method is equally unreliable. Due to the decrease in nipple intake, milk secretion, and milk concentration in infants, the inhibitory effect of lactation hormones on gonadotropins is weakened, and the ovaries recover function from a resting state during lactation, expelling mature eggs, and gradually resuming the menstrual cycle. A survey shows that 5% -10% of pregnant women become incredibly pregnant during breastfeeding.

Therefore, women have the characteristics of ovulation first and menstruation later, and even during breastfeeding, contraception should be taken into consideration. Especially for new mothers who breastfeed less every day or have less milk or insufficient milk within six months of breastfeeding, or have been breastfeeding for more than six months, they must pay attention to contraception.
