The probability of pregnancy from external ejaculation?

Hello, Director Du: I apologize for my anxiety and concerns, and I would like to ask you about the following: 1) If my partner experiences ejaculation on their chest during urination, which is the second ejaculation of the day, and there are two small drops of semen (approximately 1/5 or less of the normal ejaculation volume) on their external genitalia, and after one to two minutes, my partner wipes their external genitalia with toilet paper, the app indicates a [moderate chance of conception].
If a small amount of semen accidentally enters the vagina, is there a possibility of pregnancy? 2) After wiping off the remaining semen from other areas, if my partner takes a shower and washes other parts of their body first before washing their external genitalia, is there a chance that the remaining trace amounts of semen could enter the vagina and lead to pregnancy?

Hello: 1) If a partner ejaculates on their chest while using the restroom, and this is the second ejaculation of the day, with two small drops of semen (approximately one-fifth or less of a normal ejaculation volume) on the partner's vulva, and after one to two minutes, the partner wipes the vulva with toilet paper, and the app indicates a [moderate chance of conception] period, is there a possibility of pregnancy if a small amount of semen accidentally enters the vagina? ---》 Yes, there is a possibility if a small amount of semen accidentally enters the vagina, but the chances are very low because conception is not that easy.
2) After wiping the remaining semen from other areas, if the partner later takes a shower, washing other areas first before washing the vulva, is it possible for the remaining trace amounts of semen to enter the vagina and cause pregnancy? ---》 Similarly, it is unlikely.
Wishing you good health.

When it comes to the question of whether precum (pre-ejaculate fluid) can lead to pregnancy, it is essential to understand the mechanics of conception and the factors involved in the reproductive process.
1. Understanding Precum: Precum is a fluid released by the male during sexual arousal before ejaculation. It is primarily meant to lubricate the urethra and neutralize any acidity that may be present due to urine. While it is often assumed that precum does not contain sperm, studies have shown that it can contain viable sperm, especially if the male has recently ejaculated. This means that there is a potential risk of pregnancy even if ejaculation does not occur inside the vagina.

2. Risk of Pregnancy from External Contact: In your scenario, where there were two drops of semen on the partner's external genitalia, the risk of pregnancy exists, albeit it is relatively low. If the semen were to come into contact with the vaginal opening, there is a possibility that sperm could travel into the vagina, especially if the timing coincides with the partner's fertile window. The fertility window is typically a few days before ovulation, when the chances of conception are highest.

3. Wiping and Washing: After the partner wiped the external genitalia with a tissue, the risk of sperm leading to pregnancy decreases significantly. However, if there were any residual sperm on the tissue or if the partner did not wash thoroughly before washing the external genitalia, there remains a slight risk. Sperm can survive outside the body for a short period, and if any sperm were to be transferred to the vaginal area, there could be a chance of pregnancy.

4. Contraceptive Measures: If avoiding pregnancy is a priority, it is crucial to use effective contraceptive methods. Condoms, hormonal birth control, or other forms of contraception can significantly reduce the risk of unintended pregnancy. Relying solely on withdrawal or the timing of intercourse is less reliable.

5. Fertility Awareness: Understanding the menstrual cycle and recognizing signs of ovulation can help in making informed decisions about sexual activity. Apps that track fertility can provide insights, but they should be used in conjunction with other methods for greater accuracy.

6. Consulting a Healthcare Professional: If there are concerns about potential pregnancy or if there are questions about fertility and reproductive health, it is advisable to consult a healthcare professional. They can provide personalized advice based on individual circumstances and health history.

In conclusion, while the risk of pregnancy from precum is lower compared to direct ejaculation into the vagina, it is not zero. Factors such as timing in relation to the menstrual cycle, the presence of viable sperm in precum, and the method of cleaning after contact all play a role in determining the likelihood of conception. For those who wish to avoid pregnancy, utilizing reliable contraceptive methods is essential.
