Is external ejaculation a natural contraceptive?

Generally speaking, the contraceptive method that people think of is pharmaceutical contraception. But female friends also know that birth control pills still have some harmful effects on health. Therefore, natural contraception is often chosen. So, is ejaculation a natural contraceptive? In fact, in vitro ejaculation is a method of natural contraception, but it is not recommended for long-term use because it will cause some harm to men.

Although the in vitro ejaculation contraceptive method is simple, it is unreliable and has a high failure rate. The reason for the failure was that a small amount of semen had been ejected into the vagina before the man pulled his penis out of the vagina. Because ejaculation and ejaculation are a continuous action, and the time between the two is very short, most men cannot accurately grasp the timing, so that when they are about to reach orgasm, they cannot withdraw the penis from the vagina in time, so that the initially ejaculated semen is discharged into the woman's vagina, and this part of the semen contains the largest number of sperm, so it is easy to lead to pregnancy. This is the main reason for contraceptive failure with in vitro ejaculation.

Secondly, men often have a small amount of sperm entering the vagina before ejaculation occurs. This is the sperm accumulated in the vas deferens. During sexual excitement, as the vas deferens contracts, it is first discharged into the urethra, and then overflows into the vagina along with urethral secretions. This phenomenon of sperm spillage before ejaculation is uncontrollable and can lead to contraceptive failure.

In vitro ejaculation contraception is a method of intercourse interruption contraception. In order to prevent semen from being ejaculated into the vagina, both couples (especially the man) are highly nervous during sexual intercourse, and suddenly interrupt the sexual intercourse at the climax. This will affect the occurrence of orgasm, fail to achieve sexual satisfaction, and lead to neurasthenia over time. Some men may develop sexual dysfunction, such as premature ejaculation, impotence, etc. Since this method has poor contraceptive effect, it should not be used when there are many contraceptive methods.

Although it is logical that external ejaculation will not lead to pregnancy, in fact we have also seen couples who have unexpected pregnancies due to external ejaculation.

Some people think that as long as they don't ejaculate inside their bodies, they won't get pregnant and don't take any safety measures. In fact, if the hymen is not broken, it does not mean that sperm cannot swim into the uterus. The hymen has holes in the middle and is not a completely closed membrane, otherwise a woman's menstruation will not come out. “Even if there is no internal ejaculation, a small amount of semen will remain in the woman's body during previous sexual intercourse, and the sperm will swim into the uterus. If it happens to be a woman's ovulation period, once the sperm and egg meet, pregnancy will occur.

In vitro ejaculation refers to a method in which the penis is pulled out during sexual intercourse and when ejaculation is about to occur, so that the semen is ejected outside the woman's body. It is often used as a method of contraception, but this method is unreliable and harmful to the body.
