2. 4 things you know about contraception, do you know them all?

1. Do condoms have to be replaced with new ones after 15 minutes of use?

There is no standard answer to this question. If both partners still don't feel discomfort or a broken condom after 15 minutes, it's perfectly fine not to change the condom. The company's main goal is to provide the best possible service to its customers.

2. What should I do if I find out afterwards that the condom is broken?

There are many reasons for condom breakage, such as inadvertent tearing or excessive force during the process. The first thing you need to do is to take the emergency contraceptive pill, which is recommended to be taken within 24 hours, but the probability of failure increases after 48 hours. Note that the pill should not be taken for a long time, and it is recommended to take the pill <3 times in a year.

3. Is it okay to not wear a condom during the safe period?

The safe period refers to a woman's non-ovulatory period, which is the follicular phase after her period ends and the luteal phase before she arrives. It is generally believed that the 7 days before the onset of menstruation and the 8 days after the start of menstruation are safe periods, but it is actually difficult to calculate a woman's safe period accurately. Once the menstrual period is delayed or prolonged, the safety period will also change, and for women who have irregular periods, the safety period is not at all feasible. Even for women with regular menstrual periods, the probability of safety period contraception failing is as high as about 50%.

4. In vitro ejaculation won't get you pregnant?

Many men will coax girls into saying that in vitro ejaculation won't get them pregnant in order to not wear a condom, and many women have suffered because of it. The rate of contraception for in vitro ejaculation is only 27%, reminds Ms. Zheng Wei of the West China Women's and Children's Hospital. On the one hand, it is because men have difficulty controlling the rhythm of ejaculation and may ejaculate before they withdraw, and on the other hand, male sperm will be discharged not only at the last moment, but there may be sperm within the secretions before intercourse, not to mention some secretions during the process. So, in vitro ejaculation contraception is very unreliable!

3. Condoms have 2 "side effects" that both men and women know about

Many people's preferred method of birth control is to use condoms, but they have "side effects" too, you know?

Condoms are not 100% guaranteed, and there is a 2% chance of failure when worn correctly. The first thing you need to do is to make sure that you are not using the condom in the wrong way, such as not evacuating the air in the reservoir before use, or breaking the condom when you tear open the package.

It is important to check for condom breakage after daily use, and for couples who do not have a need to have children, it is important to take the emergency contraceptive pill to remedy any breakage.

Most condoms on the market are made of latex, and some people who are allergic to latex may also experience allergies after using condoms, which can manifest as itching, swelling, and burning sensations in the private parts.

Four, before using condoms, 4 things must not do

Condom use also exists a lot of elementary school, if you do these things before using, the chances of contraceptive failure will greatly increase.

1. Bite with your teeth

Opening the condom bag with your teeth is likely to break the condom, and if you don't find it in time to use it as usual, it is likely to fail.

2. Not emptying the air at the front

Before using condoms, pay attention to emptying the air at the front to avoid excessive pressure during the process leading to condom rupture or causing it to slip off.

3. Get the front and back wrong

Condoms also need to be clear about the front and back, with the outside of the rolled edge being the front and the inside being the back. The wrong side of the condom will increase the risk of the condom falling off.

4. Withdraw too late

Many men want to stay warm for a while and then wait until their genitals are weak before withdrawing from the woman, but this is very undesirable. The size of the genitalia will shrink after the weakness, which is likely to allow semen to escape and increase the probability of unwanted pregnancy in women.
