Chances of external ejaculation during ovulation

First, we need to understand how ejaculation works. In vitro ejaculation means that during sexual intercourse, a man ejaculates his sperm into a woman's body and then immediately withdraws it from the body. This method reduces the chance of sperm entering the woman's body, thereby reducing the risk of pregnancy.

So, what are the chances of ejaculation outside the body?

The chance of pregnancy from in vitro ejaculation is very low. According to research by scientists, during the ovulation period of a woman, when a man ejaculates sperm into a woman, the chance of pregnancy is about 0.0017%. However, this does not mean that ejaculation is 100% safe. In fact, the risks of pregnancy still exist and may be higher.

Why does ejaculation reduce the risk of pregnancy?

In vitro ejaculation can reduce the risk of pregnancy for several reasons:

1. Reduce the number of sperm: When ejaculating outside the body, the man ejaculates the sperm into the female body and then immediately withdraws it from the body, which can reduce the number of sperm. In this way, the number of sperm in a woman's body is reduced, thereby reducing the risk of pregnancy.

2. Reduce the combination of sperm and eggs: During in vitro ejaculation, the man ejaculates the sperm into the female body and then immediately withdraws it from the body, which can reduce the combination of sperm and eggs. In this way, the number of sperm in a woman's body is reduced, thereby reducing the risk of pregnancy.

3. Reduce the quality of fertilized eggs: During in vitro ejaculation, the man ejaculates the sperm into the female body and then immediately withdraws it from the body, which can reduce the quality of the fertilized eggs. In this way, the number of sperm in a woman's body is reduced, thereby reducing the risk of pregnancy.

However, in vitro ejaculation is not a complete guarantee against pregnancy. In fact, the risks of pregnancy still exist and may be higher. If you do not want to get pregnant, it is recommended to take other safety measures, such as using condoms or oral emergency contraceptive pills.

In summary, in vitro ejaculation is safe in most cases, but there are still certain pregnancy risks. If you don't want to get pregnant, take other safety measures.
