Can I get pregnant?


Hello doctor, my girlfriend's menstrual cycle is approximately 30 days.
This month, she is expected to start her period tomorrow, October 22.
On October 21 at around 1 AM, my girlfriend helped me with manual stimulation, and I ejaculated onto a tissue.
However, her genitals were about five centimeters away from me, and we visually confirmed that there was no ejaculation onto her.
If a small drop of semen accidentally landed on her, what is the likelihood of her becoming pregnant? What is the probability?

Your girlfriend's menstrual cycle is approximately 30 days, and she is expected to start her period on 10/22.
On the early morning of 10/21, while she was giving you a handjob, you ejaculated onto a tissue.
Since her genital area was about five centimeters away, and you visually assessed that no semen reached her, the likelihood of pregnancy is very low, even if a small drop accidentally landed nearby.
The chances of conception in this scenario are minimal.

When it comes to the question of whether pregnancy can occur from precum (pre-ejaculatory fluid), it's important to understand the biological mechanisms involved in conception and the nature of precum itself.

Precum is a fluid that is released from the penis during sexual arousal, before ejaculation. Its primary function is to lubricate the urethra and neutralize any acidity that may be present, creating a more favorable environment for sperm. While precum itself does not typically contain sperm, there is a possibility that it can pick up sperm that may be left in the urethra from a previous ejaculation. This is particularly relevant if there has been a recent ejaculation before the precum is released.

In your scenario, you mentioned that your girlfriend's menstrual cycle is approximately 30 days, and you engaged in sexual activity just before her expected period. The timing of intercourse in relation to the menstrual cycle is crucial because a woman is most fertile during ovulation, which typically occurs around 14 days before the start of her next period. If her cycle is regular, she would likely be less fertile just before her period, which reduces the chances of conception.

However, the risk of pregnancy from precum, even if it contains a small amount of sperm, cannot be entirely dismissed. The likelihood of pregnancy from precum is generally considered to be lower than from full ejaculation, but it is not zero. Studies suggest that the chances of pregnancy from precum are significantly lower than from ejaculate, but exact probabilities can vary based on several factors, including the presence of viable sperm in the precum and the timing of the menstrual cycle.

To address your specific question about the likelihood of pregnancy given that you were approximately five centimeters away and there was a possibility of a small amount of precum coming into contact with her genital area: while the risk is low, it is not impossible. If there was indeed sperm in the precum and it made its way into the vaginal canal, there is a chance of pregnancy, albeit a small one.

If you and your girlfriend are concerned about the possibility of pregnancy, it is advisable to consider emergency contraception if the sexual encounter was recent and falls within the appropriate time frame for such methods. Additionally, if she misses her period, taking a home pregnancy test or consulting with a healthcare provider would be the next steps to confirm whether or not she is pregnant.

In summary, while the chances of getting pregnant from precum are relatively low, they are not nonexistent. Understanding the timing of the menstrual cycle and the nature of precum can help in assessing the risk. If you are looking to avoid pregnancy, using reliable contraception methods is essential.
