Although modern contraceptive technology has improved greatly, and contraceptive effects have also been improved, there are still quite a few couples to choose external ejaculation to achieve the purpose of contraception.As everyone knows, this method may lead to a series of adverse reactions, so it is not advocated.So, what is the harm of male ejaculation?
The harm of men's ejaculation
1. Causes functional non -ejaculation
During the sexual intercourse, the penis erection is harder before ejaculation.If you forcibly interrupt sex at this time, in vitro exclusion will cause the function of the central nervous and lumbosacral ejaculation center.Over time, it is easy to be dysplained without ejaculation.
2. Cause sexual weakness
During the whole process of sexual life, its sexual reactions are completed under the control of the cerebral cortex.The psychological and physiological stimulus in sexual intercourse will cause a series of changes. High excitement will cause mental tension, accelerate heartbeat, and increase blood pressure.At the same time, the reproductive organs are erected as penile blood vessel congestion and muscle contraction.If you suddenly interrupt sexual intercourse when reaching the climax, it will inevitably have adverse effects on sexual psychology. Over time, it is prone to sexual weakness and cause premature ejaculation and other symptoms.
3. Make women cold
When the sexual intercourse reached the climax, the woman did not get sexual satisfaction at this time. The man forcibly interrupted sexual intercourse, and the in vitro was excited.To continue, it will lead to coldness.
In addition, in vitro radon method may be the most popular contraceptive method in the world and the lowest efficiency.According to statistics, if a hundred couples use this method to contraception, thirty women will get pregnant.

The best way for men
Use condom
Condoms are a convenient and promoted male contraceptive tool.The deliciousness of condom contraception has no side effects on both sides. The method of use is simple, but it will affect the feelings of men, and the contraceptive rate is not 100%.According to statistics, if the condom can be used correctly, the failure rate is only 1.5 to 4.2%.However, in the actual use of condoms, the failure rate is as high as 10 to 15%.The main reason is that in the process of using condoms, some minor last quarters are not noticed. If it is used correctly, the contraceptive rate is still very high.
Ligation
Male ligation surgery is a permanent contraceptive method.The principle of contraception is to cut off the sperm -transmitting tube transporting sperm from the testicular to the penis, so that the sperm cannot enter the inside of the semen and eliminate the in vitro.Men will not immediately have the effect of permanent contraception after undergoing ligation surgery. Therefore, other reliable contraceptive measures must be used after surgery. It is not until two sub -examinations that prove that there is no sperm -free existence before you can abandon contraceptive measures.
