First place: In vitro semen ejaculation

This is an ancient contraceptive method. In the past, when there was a lack of contraceptives, many people used this method to prevent pregnancy. Although the in vitro ejaculation contraceptive method is simple, it is unreliable and has a high failure rate. Before the man withdraws his penis from the vagina, a small amount of semen has been ejected into the vagina. Because ejaculation and ejaculation are one continuous action, and the time between the two is extremely short, most men cannot accurately grasp the timing. As a result, when they are about to reach orgasm, they cannot withdraw their penis from the vagina in time to prevent the initial ejaculation. Semen is discharged into a woman's vagina, and this part of the semen contains the largest number of sperm, so it can easily lead to pregnancy. This is the main reason for contraceptive failure with in vitro ejaculation.

Second place: Calculating ovulation period

Calculating female ovulation period is a natural contraceptive method that does not use any contraceptive measures. The advantage is that it will not cause any impression or side effects on the body, but it fails. The rate is very high. Firstly, it is because women's ovulation periods often vary, making it difficult to accurately calculate the ovulation period. Secondly, it requires full cooperation between the couple to establish a regular sex life. This calculation method is often unreliable, because the time of a woman's ovulation is affected by factors such as the external environment, climate, her mood, and health status. As a result, ovulation may be delayed or advanced, and additional ovulation may occur. In addition, the longest survival time of sperm and eggs in the female reproductive tract cannot be determined conclusively. Therefore, the safe period cannot be accurately calculated, so contraception during the safe period is not safe.

Third place: Condoms

Most people choose condoms as a contraceptive method because they are convenient to purchase and easy to use. However, condoms are easily affected by human factors during use, such as Improper wearing, falling off or being torn, etc. will affect the contraceptive effect. In addition, some people may be allergic to rubber products, causing discomfort, and some people think that using condoms will affect pleasure. However, condoms can prevent sexually transmitted diseases and infectious diseases. Therefore, it is recommended to use it together with other contraceptive methods.

Fourth place: Uterine ring

The intrauterine ring is a long-term contraceptive method that can remain in the uterus for up to 5 years and has a high contraceptive success rate. However, some people, especially young women or women who have never given birth, may be repulsed by it and cause discomfort. In addition, wearing a ring may increase and prolong menstruation, and may cause bleeding outside menstruation.

Emergency contraceptive pills ≠ regret pills

Every year around Valentine’s Day, there is always a sales peak of emergency contraceptive pills. Couples who are desperate for love regard emergency contraceptive pills as "regret medicine" or "Buddha's feet" that can be hugged temporarily. They hope that a small pill can solve the serious consequences of unexpected pregnancy due to the failure to implement contraceptive measures in advance. Friends who have this plan, please note that this idea is out!

Emergency contraceptive pills are an afterthought and cannot be used as a regular method of contraception. This method achieves the purpose of post-event contraception by inhibiting ovulation and interfering with egg fertilization or implantation. The commonly used component is mostly a single large-dose progesterone (equivalent to 8 times the dose of short-acting oral contraceptives). Due to the dosage If it is larger, it will interfere with normal endocrine and easily lead to menstrual cycle disorders, irregular vaginal bleeding and other symptoms. Repeated use will have health effects, such as menstrual disorders, amenorrhea, etc. Thirdly, emergency contraceptive pills are irritating to the gastrointestinal tract, and vomiting may occur after taking them. If the pill is not taken again after vomiting, the contraceptive effect will be further compromised. Women who have had unprotected sex many times during a menstrual cycle should not use emergency contraception. Moreover, research data shows that emergency contraceptive pills are only 85% effective and are not foolproof. In other words, even if emergency contraceptive pills are used, there is still a risk of unwanted pregnancy.

So taking emergency contraceptive pills afterwards is by no means a healthy method of contraception. Only by paying attention to contraception beforehand can intimate life be safe and worry-free.
