The contraceptive effect of ejaculation outside the body is very poor, and accidental pregnancy is easy to occur. If sufficient and safe contraceptive measures are not taken, emergency contraceptives should be taken promptly after sexual behavior, which can achieve the effect of post-hoc remediation and thus reduce the probability of accidental pregnancy for women.

Questions and Answers Regarding Ejaculation Outside the Body and the Use of Contraceptives

1. Is it necessary to take contraceptives after ejaculation outside the body?

Many people mistakenly believe that ejaculation outside the body cannot lead to pregnancy for women. However, this is a very wrong assumption. During sexual intercourse, men usually secrete some prostatic secretions, which contain a large number of sperm. Therefore, even if ejaculation occurs outside the body, there is still a significant chance of pregnancy for women. Men should never rely on this method for contraception. If sufficient and safe contraceptive measures are not taken, emergency contraceptives should be taken promptly after sexual behavior to achieve the effect of post-hoc remediation and reduce the probability of accidental pregnancy for women.

2. Precautions for Taking Contraceptives

Although contraceptives can serve as a post-hoc remedy, they also have significant side effects, which can easily lead to menstrual irregularity, lower abdominal pain, abnormal vaginal bleeding, dizziness, nausea, and other symptoms. Therefore, after taking contraceptives, women should closely monitor their physical condition, rest more, and avoid being in a state of fatigue, as this may exacerbate symptoms. If symptoms are severe, women should seek medical attention promptly for treatment to avoid causing more serious health issues.

3. Scientific Methods of Contraception

Male Condoms: Success Rate of 80%-90%

Principle: Prevent sperm from encountering eggs. Method: Men should wear the condom on their genitalia before sexual activity. Note: Condoms are the most commonly used method among young people. Their biggest advantage is that they do not interfere with women's physiology and can also prevent sexually transmitted diseases.

Intrauterine Devices (IUDs): Success Rate Over 95%

Principle: Prevent the implantation of fertilized eggs in the uterus. Method: Inserted into the uterus by a doctor. Note: The placement and removal of IUDs require certain procedures. After insertion, there may be slight increases in menstrual flow, menstrual cramps, or the induction of inflammation. They are mostly used for postpartum women. Before getting an IUD, women should undergo a medical examination. Women with gynecological inflammation, irregular or excessive menstruation, or reproductive organ tumors are not suitable for IUDs.
