What is the success rate of contraception during extracorporeal ejaculation? What are the hazards of long-term external ejaculation
1. What is Coitus interruptus contraception?
During sexual activity, the penis is immediately removed before ejaculation, and semen is discharged outside the vagina for the purpose of contraception. Coitus interruptus is a very old contraceptive method. However, many people still use it. It is estimated that 35 million couples in the world use this method, accounting for about 8% and 7% of all birth control measures. The proportion used by developed countries is significantly higher than that of developing countries.
2. Advantages of Coitus interruptus contraception
The advantage of Coitus interruptus is that it does not require any contraceptives or expert guidance, and the couple only need to cooperate for a period of time.
3. Disadvantages of Coitus interruptus contraception
One of its drawbacks is the decisive withdrawal of the penis when about to ejaculate, which can easily lead to interruption of sexual intercourse and affect the sexual satisfaction of both spouses. Secondly, men often have deep demands when they are about to ejaculate., At this point, if you hesitate, you may flow a small amount of semen into the vagina, leading to contraceptive failure. Due to the aforementioned shortcomings, previous literature often held a negative attitude towards this method. We do not advocate the widespread use of extracorporeal ejaculation contraception.
4. Causes of contraceptive failure of Coitus interruptus
Why is Coitus interruptus prone to contraceptive failure? Firstly, there is the pleasure of ejaculation approaching, as it is difficult for men to control it. Secondly, even if they can control it, they cannot ejaculate inside the body., It is also possible that some sperm may enter the body during sexual intercourse, and the possibility of pregnancy cannot be ruled out.
The above is the introduction of Coitus interruptus contraception. Because the effect of Coitus interruptus contraception is not reliable, and it is also easy to lead to premature ejaculation, it is not recommended to use this method.
Hazards of Coitus interruptus
1. Contraceptive failure
Coitus interruptus refers to the orgasm of sexual intercourse, the instant of ejaculation, the sexual intercourse is immediately interrupted, so that semen is discharged outside. This natural contraceptive method often fails to achieve the purpose of contraception., What is the reason? There are three reasons for failure: before ejaculation, sperm cells usually shed a few drops from the urethral orifice with the contraction of the Vas deferens. Each drop of sperm contains about 50000. If it flows into the vagina, if it flows into the vagina, one drop of semen is enough to fertilize women; At the most tense stage of the sprint, the time for pulling out the penis may be too late because the man is attached to pleasure and ejaculates some of the semen into the vagina; Sometimes after coitus interruptus, a man immediately touches a woman's penis with his hands to make her reach orgasm. The second sexual intercourse may not last long. In both cases, the fingers and penis can bring sperm into the vagina again.
