Can Pre-Ejaculation During Dangerous Days Lead to Pregnancy?

Dangerous period of withdrawal method (coitus interruptus)

Hello, doctor.
I would like to ask about the situation where my girlfriend and I had intercourse during her fertile period.
I consistently used a condom throughout, but at the end, I removed it because we had been going for a long time.
I pulled out and ejaculated on her buttocks, and some of it may have flowed onto her labia.
I immediately cleaned it up, and the amount was very small.
Recently, I have been staying up late.
Before I ejaculated, none of it went inside.
What is the likelihood of pregnancy in this situation?

When it comes to the question of whether pre-ejaculation during the fertile window can lead to pregnancy, it is important to understand the mechanics of conception and the role of pre-ejaculatory fluid. Pre-ejaculation, or pre-cum, is a fluid released by the penis before ejaculation. While it is primarily meant to lubricate the urethra and neutralize acidity, it can also contain sperm. The presence of sperm in pre-ejaculatory fluid is a topic of debate, but studies suggest that it is possible for pre-ejaculation to contain viable sperm, especially if there has been a recent ejaculation.

In your case, you mentioned that you used a condom throughout the sexual activity and only removed it before ejaculation. This is a good practice as condoms are highly effective in preventing pregnancy when used correctly. However, you also noted that some of the ejaculate may have come into contact with the vaginal area. This could potentially increase the risk of pregnancy, albeit the risk remains relatively low if the condom was used properly and there was no direct ejaculation inside the vagina.

The timing of your sexual activity is also crucial. The "dangerous days," or fertile window, typically occurs around ovulation, which is usually about 14 days before the start of the next menstrual period in a regular cycle. If your girlfriend was indeed in her fertile window, the chances of conception could be higher, especially if sperm were present near the vaginal opening.

It is also worth noting that factors such as the timing of ovulation, the lifespan of sperm (which can live up to five days in the female reproductive tract), and the overall health of both partners can influence the likelihood of pregnancy. If your girlfriend has a regular menstrual cycle, tracking her ovulation can provide more insight into her fertile days.

In summary, while the risk of pregnancy from pre-ejaculation during the fertile window exists, it is significantly reduced when using condoms correctly. If you are concerned about the possibility of pregnancy, it may be wise for your girlfriend to take a pregnancy test if her period is late, or to consult with a healthcare provider for further advice. Additionally, if you are looking to prevent pregnancy in the future, consider discussing more reliable contraceptive methods with your partner.
Lastly, it is essential to maintain open communication with your partner about sexual health and contraception to ensure both of you are comfortable and informed about your choices.
