Failure rate of in vitro ejaculation during ovulation

In vitro ejaculation refers to the process in which a man fertilizes a woman outside her body during sexual intercourse. Although this method is simple and easy to implement, the failure rate is very high. According to research, during the ovulation period, a woman’s egg can survive for 4-5 hours, while the survival time of sperm is longer, usually 3-4 days. This means that even if IVF is successful in a woman, the sperm may survive in the woman's body for a period of time, leading to pregnancy.

In addition to the failure rate, there are other risks associated with ejaculation. For example, a man may produce some sperm during sexual intercourse, which may enter the woman's body and lead to pregnancy. In addition, men may reduce the number of sperm during sexual intercourse due to factors such as fatigue, illness, or drugs, which will also increase the failure rate of in vitro ejaculation.

Therefore, although in vitro ejaculation may be a convenient and quick method, there are certain risks and failure rates in actual operation. If you are considering using this method, it is recommended to do enough research and understanding to ensure you can implement it safely. If you have tried in vitro ejaculation and become pregnant, it is recommended to seek medical treatment in time for further treatment.
