Don't use these four unreliable contraceptive methods anymore? Which contraceptive methods are very harmful to the body

With the popularization of medical knowledge, most people know that induced abortion is a surgery that causes significant physical harm to women, and can even lead to infertility in severe cases. Therefore, many women do a good job of contraception without planning to have children, but not every couple can use the correct contraception method. So far, many people are still using unreliable contraception methods.

Which contraceptive methods are unreliable?

1. Coitus interruptus

Coitus interruptus is a very unreliable method of contraception, but many people have tried it. Firstly, not everyone can control it well in advance. If not, it may lead to unexpected pregnancy. Additionally, a small amount of sperm may be expelled before ejaculation. Although women have a lower chance of conception, there is still a chance of pregnancy.

2. Safe period contraception

Many couples or couples use safe period contraception for contraception, but in reality, this method of contraception is also unreliable. Many women believe that the first 7 days of menstruation and the last 8 days of menstruation are safe periods, during which they do not ovulate. In fact, not every woman's ovulation period is regular. If the ovulation period is advanced or delayed, safe contraception will fail.

3. Vaginal flushing

Many people believe that flushing the vagina after sexual intercourse can flush all semen out of the body and have a contraceptive effect. In fact, this method of contraception is not only unreliable, but also unscientific. In fact, the speed of sperm dissociation is particularly fast, and the vagina and cervix are not as long as imagined. Sperm and egg can meet in a short period of time, so flushing the vagina afterwards cannot have any contraceptive effect.

4. Emergency contraceptive pills

The emergency contraception is a remedial method after the event, which can prevent the zygote from implanting normally and has contraceptive effect. Firstly, the contraceptive effect of emergency birth control pills is not 100%, and there is still a possibility of missing the net. In addition, there are too many estrogen and progesterone in acute contraceptives. If used too frequently, it can cause hormonal disorders in the human body, leading to menstrual irregularities in women, and in severe cases, even infertility.
