There are many methods of contraception, and different women require different contraceptive methods. However, no matter which contraceptive method is used, it is important to choose a safe and effective contraceptive method. Coitus externa is a very common method of contraception. During sexual intercourse between a man and a woman, the man comes out of the woman's body when he is about to ejaculate and ejaculates outside the body. In fact, this is a very unsafe method of contraception. Coitus externa refers to the man pulling his penis out of the vagina before ejaculation, and ejaculating semen outside the vagina, so that the sperm cannot meet the egg, thus achieving the purpose of contraception. It is easy to get pregnant using this method because during sexual intercourse, when sexual pleasure reaches its peak, if the movement slows down a little, semen will be ejaculated into the vagina, causing contraceptive failure. In addition, this method can easily make both men and women nervous because they pay too much attention to the time of ejaculation, making the sexual intercourse process insatiable, and even causing sexual neurasthenia over time. Which contraceptive method is more effective? Surgical contraception Surgeries such as IUD insertion, tubal ligation, and vasectomy are also options for many people. These methods are suitable for couples who do not want to have children in the future. They can solve the problem once and for all, but they are not recommended for young couples. As a surgery, it is harmful to the body after all, and the IUD is a foreign object and is not 100% contraceptive. It is also a health hazard. Safe period contraception The so-called safe period contraception refers to calculating the time of ovulation and cleverly staggering the days when sperm and egg are easily combined to conceive, thereby achieving the purpose of contraception. This method seems good, but sometimes women have irregular menstrual periods and ovulation periods are difficult to calculate, which can easily lead to contraceptive failure. According to statistics, the failure rate of contraception during the ovulation period is as high as about 20% within one year. Contraceptive pills for contraception As a kind of exogenous hormone, birth control pills work by changing the state of cervical mucus and preventing sperm from penetrating, thus achieving the contraceptive effect. Contraceptive pills can be beneficial if taken under professional guidance. But it is worth noting that long-acting contraceptives must be taken accurately, on time and in the right amount, otherwise it may easily cause irregular bleeding or contraceptive failure. Sometimes, even if you take the medicine on time and in the right amount, side effects may still occur, such as breast tenderness, menstrual disorders, gastrointestinal reactions, etc. Especially taking emergency contraceptive pills, the harm will be greater. Condoms for contraception Condoms are currently the most mainstream method of contraception, with a contraceptive efficiency of up to 98%. They use special materials to separate the male and female reproductive organs to prevent the sperm and egg from combining, thereby achieving the purpose of contraception. Because there is no direct contact, the use of condoms can achieve the effect of blocking sexually transmitted diseases. But female friends must keep their eyes open when choosing condoms, because many condoms on the market currently contain silicone oil. Long-term use can easily damage the female vaginal environment and cause gynecological diseases. Using hyaluronic acid as a condom lubricant is the best choice! |
