Can I get pregnant?


Hello doctor, last Wednesday (the 15th), my boyfriend masturbated and after he ejaculated, he put his pants back on but his underwear was wet.
Then I sat on him (while wearing pants).
Is there a chance I could get pregnant from this?

Hello, based on your description, the chances of becoming pregnant are low but not impossible.
As long as there are active sperm in the vagina during the ovulation period, there is still a possibility of pregnancy regardless of the method.
It is advisable to take appropriate contraceptive measures, and if necessary, consult a physician for evaluation.
Thank you! Wishing you safety and health.
Dr.

The concern about the possibility of pregnancy from wet clothes after a sexual encounter is a common question, and it's important to understand the mechanics of conception to address it accurately.

To begin with, pregnancy occurs when sperm fertilizes an egg. For this to happen, sperm must be deposited in or near the vaginal canal, where it can travel through the cervix and into the uterus to meet an egg. In your scenario, the key factor is whether sperm was present on the wet clothing that came into contact with your genital area.

1. Sperm Viability: Sperm can survive outside the body for a limited time, but they require a specific environment to remain viable. Sperm exposed to air and moisture on clothing typically do not survive long enough to cause pregnancy. Once sperm dries, they lose their ability to fertilize an egg. If your boyfriend ejaculated into his underwear and then put on pants, the likelihood of viable sperm being transferred to you through clothing is extremely low.

2. Clothing Barrier: The presence of multiple layers of clothing (such as pants and underwear) acts as a barrier that significantly reduces the chances of sperm reaching the vaginal area. Even if the underwear was wet, the sperm would have to be in a sufficient quantity and in the right condition to potentially lead to pregnancy, which is highly unlikely.

3. Direct Contact: For pregnancy to occur, there typically needs to be direct contact between sperm and the vaginal canal. In your case, since you were wearing pants and there was no direct transfer of sperm, the risk of pregnancy is minimal.

4. Other Considerations: It's also important to consider that while the risk of pregnancy is low, there are still risks of sexually transmitted infections (STIs) if there was any direct contact with bodily fluids. If you have concerns about STIs, it would be wise to consult a healthcare provider for testing and advice.

5. When to Worry: If your menstrual cycle is irregular or if you experience any unusual symptoms, it may be worth taking a pregnancy test or consulting a healthcare professional for further guidance. Pregnancy tests are most accurate when taken after a missed period.

In conclusion, based on the scenario you described, the likelihood of becoming pregnant from sitting on wet clothes after your boyfriend ejaculated is extremely low. However, if you have any lingering concerns or if your circumstances change, seeking advice from a healthcare provider is always a good step. They can provide personalized guidance and support based on your specific situation.
