Can You Get Pregnant from Semen on Underwear During Foreplay?

The likelihood of becoming pregnant from semen on underwear is extremely low. For pregnancy to occur, sperm must be deposited in the vaginal canal, where it can travel to fertilize an egg. If semen is on underwear, the chances of sperm

Hello Doctor: I have a question.
Yesterday, on July 11th, my girlfriend and I were touching each other (without any penetration).
I felt like I was about to ejaculate, so I stopped her and put my underwear back on.
I ended up ejaculating in my underwear, which became wet.
While helping my girlfriend put her underwear back on, we embraced.
Is there a possibility that the semen on my wet underwear could come into contact with her underwear or thigh and cause pregnancy? Her menstrual cycle is irregular; the last time she had her period was on June 21st.
She mentioned that her discharge has been increasing lately.
Could this indicate that she is in her ovulation period?

More Info

The question of whether pregnancy can occur from semen on underwear during foreplay is a nuanced one. To address this, it is essential to understand the mechanics of sperm transfer and the conditions necessary for conception.

Semen contains sperm, which are the male reproductive cells necessary for fertilization. For pregnancy to occur, sperm must travel from the male's body to the female's reproductive tract, specifically the vagina, and then into the uterus where fertilization of an egg can take place. In the scenario described, the male ejaculated into his underwear, and then there was contact between his underwear and the female's body.

While it is theoretically possible for sperm to be transferred from wet underwear to the female's genital area, the likelihood of this resulting in pregnancy is extremely low. Sperm are quite fragile and do not survive long outside the human body. Once exposed to air and the fabric of clothing, sperm begin to die rapidly. Additionally, the sperm must be in a viable state and in sufficient quantity to reach the cervix and travel through the uterus to fertilize an egg.

In this case, the male's underwear was wet with semen, but the transfer of sperm to the female's body would require direct contact with the vaginal area. Even if some sperm were to be transferred, the chances of them being motile and capable of fertilization are significantly diminished due to the exposure to air and the fabric of the underwear.
Regarding the female's menstrual cycle, if her last period was on June 21 and her cycles are irregular, it is difficult to predict her ovulation accurately. Ovulation typically occurs about 14 days before the start of the next menstrual period, but this can vary widely in women with irregular cycles. Increased vaginal discharge can be a sign of approaching ovulation, but it is not definitive.

In summary, while the possibility of pregnancy from semen on underwear during foreplay exists, it is highly unlikely. The conditions required for sperm to survive and successfully fertilize an egg are not typically met in such scenarios. If there are concerns about potential pregnancy, it is advisable for the female partner to take a pregnancy test if her period is late or if she experiences any pregnancy symptoms.

For future reference, if avoiding pregnancy is a priority, it is essential to use reliable contraception methods consistently. Additionally, understanding the menstrual cycle and recognizing signs of ovulation can help in planning or preventing pregnancy effectively. If there are any further concerns or questions about sexual health or reproductive issues, consulting with a healthcare provider is recommended for personalized advice and guidance.
