What other contraceptive methods are there besides in vitro ejaculation

Many men and women use extracorporeal ejaculation contraception during sex, but in fact, this method is indeed the most unreliable method, in addition to leading to contraceptive failure, but may also lead to male sexual coldness. So, what is the harm of in vitro ejaculation?
The harm of ejaculation in vitro
1. Easy to cause sexual neurasthenia
Throughout the sexual life, the male sexual response is completed under the control of the cerebral cortex. Psychological and physical stimuli during sexual intercourse will cause a series of changes, and a high degree of excitement will make you nervous. My heart beats faster. Elevated blood pressure and so on. At the same time, the reproductive organs are characterized by penile vascular congestion and muscle contraction. If sexual intercourse is suddenly interrupted when it reaches the best part, it is bound to have a negative effect on sexual psychology. Over time, it is easy to have sexual neurasthenia, leading to premature ejaculation. Impotence and other symptoms.
two。 Easily lead to the failure of contraception
In vitro ejaculation means that when sexual intercourse reaches the most wonderful part, ejaculation is about to stop sexual intercourse immediately, so that semen is excreted. This natural method of contraception often fails to achieve the purpose of contraception. What is the reason? It turns out that when men and women have sex, a small amount of semen will spill to the vagina as the vas deferens contract. Although these semen have the largest number of sperm, it is easy to get pregnant.
3. Easy to cause functional non-ejaculation.
During sexual intercourse, penile erection is more difficult before ejaculation because of sexual excitement. If sexual intercourse is forcibly interrupted at this time, extracorporeal ejaculation will cause dysfunction of the central nervous system and lumbosacral ejaculation center. With the passage of time, it is easy to suffer from functional non-ejaculation.
4. It is easy to make women suffer from sexual apathy.
When sexual intercourse reaches the best part, women do not get sexual satisfaction at this time. The male forcibly interrupts the sexual intercourse and excretes the sperm in vitro, which makes the female's sexual excitement drop in a straight line and receive bad stimulation psychologically. If it goes on like this, it will lead to frigidity.
5. It is easy to cause disharmony between husband and wife
Normal, moderate and harmonious sex life can enhance the relationship between husband and wife, while extracorporeal sperm excretion, a seemingly scientific but actually unscientific method of contraception vibrator for vaginal atrophy , often leads to estrangement between husband and wife. If the woman is pregnant, the man does not think that the semen enters the vagina ahead of time, but mistakenly thinks that the woman is unfaithful, leading to a quarrel; if she forcibly interrupts the sexual life, the woman will not get sexual satisfaction, sexual psychological depression, will have an aversion to sexual intercourse, cast a shadow over the feelings of husband and wife. It can be seen that in vitro ejaculation is not enough, it is best to take other contraceptive methods between husband and wife.

1. Vaginal flushing method for contraception
Some people think that after having sex with men and women, if the woman washes her vagina, she can have contraception. This method is actually very unsafe. In the same room, if the man ejaculates, among the countless sperm, if the man ejaculates, countless sperm will soon swim into the woman's uterine cavity. At this time, no matter how much a woman washes her vagina, she can't flush all the sperm out of the body. So using vaginal flushing for contraception, women can still get pregnant.

This is not the period of ovulation for women. At this time, the husband and wife sleep together, generally will not let the woman get pregnant, so people call this period of time. & quot; safe period & quot;. But & quot; safe period & quot; this is not absolutely safe. Because some women ovulate irregularly. Some women, even if they ovulate regularly, are regular when their emotions appear. . When the living environment and physical conditions change greatly, ovulation will also lose the original rule. Therefore, it is not safe to use female safe period contraception.

4. Menopausal contraception
