What is the best method of contraception?

When people reach a certain age, they will have normal physiological needs, but only by taking proper measures can they avoid pregnancy and reduce unnecessary trouble. Contraception is also a good way to prevent disease, because many diseases are caused by bacteria, so contraception is a way to avoid disease. So let us learn about the best method of contraception. I hope everyone can choose the contraceptive method that suits them according to their physical condition.

Coitus interruptus refers to a method in which, during sexual intercourse, when ejaculation is about to occur, the penis is pulled out, causing semen to be ejaculated outside the woman's body. It is often used as a contraceptive method, but this method is unreliable and has certain harm to the body.

Although theoretically, pregnancy will not occur if ejaculation is performed outside the body, in fact, we have seen couples who accidentally became pregnant because of ejaculation outside the body. Why does this happen? In fact, when a man and a woman have sex, the man does not ejaculate sperm only when he reaches orgasm. Sperm is also ejaculated during the process, but the amount is relatively small compared to the sperm ejaculated during orgasm.

You should know that one drop of semen contains more than 20 million sperm, but only one sperm is needed to form a fertilized egg for reproduction. In addition, men cannot completely control their ejaculation outside the body. Some men forget to ejaculate because they miss the pleasure of orgasm or ejaculation, or they ejaculate slowly, and some semen is ejaculated and remains in the woman's body, which may lead to the possibility of pregnancy.

Although the withdrawal method of contraception is simple, it is not safe and has a high failure rate. The reason for failure is that a small amount of semen has been ejaculated into the vagina before the man pulls his penis out of the vagina. Because the time before ejaculation and ejaculation is a continuous action, and the time interval between the two is extremely short, most men cannot grasp the timing accurately, so that when they are about to reach orgasm, they cannot withdraw the penis from the vagina in time, causing the initial ejaculated semen to be discharged into the female's vagina. The number of sperm in this part of semen is the largest, so it is easy to cause pregnancy. This is the main reason for the failure of contraception by ejaculation outside the body.

Secondly, men often have a small amount of sperm entering the vagina before ejaculation occurs. These are sperm stored in the vas deferens. During sexual excitement, as the vas deferens contracts, they are first discharged into the urethra and then overflow into the vagina with urethral secretions. This sperm leakage before ejaculation is uncontrollable and may result in contraceptive failure.

The failure rate of external ejaculation is very high. According to statistics, if external ejaculation is used for contraception, the failure rate will be around 90%.

The above is an introduction to the best methods of contraception. Ejaculation outside the body is a relatively simple and effective method. It allows us to enjoy the pleasure of sexual life and can also effectively avoid pregnancy. However, the method of external ejaculation cannot achieve 100% contraception and is not as effective as condoms, contraceptives and other methods. Therefore, it is recommended that everyone take appropriate methods.
