Can Oral Sex and Residual Semen Lead to Pregnancy Risks?

If semen is rinsed out of the mouth and then oral sex is performed again after 20 minutes, is there a possibility of pregnancy?

Hello, Dr.
Chang.
I would like to ask, after my girlfriend performed oral sex today, there was some residual semen in her mouth, and she rinsed her mouth with water afterward.
About 20 minutes later, when we kissed, it’s possible that some residual semen was transferred to my mouth.
After kissing, I drank a few sips of water, and then I performed oral sex on my girlfriend, inserting my tongue into her vagina.
My girlfriend is currently in her safe period.
What is the likelihood of pregnancy?

Hello, based on your description, the chances of pregnancy are low due to limited activity, but it is not impossible.
As long as active sperm are present 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.

More Info

When it comes to the question of whether oral sex and residual semen can lead to pregnancy risks, it's important to understand the mechanics of conception and the specific circumstances involved in your situation.

First, let's clarify how pregnancy occurs. For a pregnancy to happen, sperm must fertilize an egg. This typically occurs through vaginal intercourse, where sperm is deposited directly into the vagina. In your case, you mentioned that your girlfriend performed oral sex and that there was residual semen in her mouth. After she rinsed her mouth and you kissed, you then performed oral sex on her, inserting your tongue into her vagina.

The likelihood of pregnancy from this scenario is extremely low for several reasons:
1. Sperm Viability: Sperm can survive outside the human body for a limited time. Once exposed to air and the environment of the mouth, the viability of sperm decreases significantly. Even if some sperm were transferred during kissing, the chances of them remaining viable and capable of fertilizing an egg are minimal.

2. Dilution: When your girlfriend rinsed her mouth with water, any residual sperm would have been diluted. Additionally, during oral sex, the sperm would have to travel through the vaginal canal to reach the cervix and then into the uterus, which is a challenging journey for any sperm, especially if they are not in optimal condition.

3. Timing of Ovulation: You mentioned that your girlfriend is in her "safe period." This typically refers to the time in her menstrual cycle when she is least likely to be ovulating. If she is indeed in this phase, the chances of pregnancy are further reduced.

4. Semen Transfer: The transfer of semen from one person to another through kissing is not a reliable method of conception. The process of sperm needing to reach the egg is quite specific, and the conditions must be just right for fertilization to occur.

In summary, while it is theoretically possible for pregnancy to occur through indirect means, the specific circumstances you described make it highly unlikely. The combination of the dilution of sperm, the time elapsed, and the timing in your girlfriend's menstrual cycle all contribute to a very low risk of pregnancy.

However, it is always wise to consider the broader implications of sexual activity, including sexually transmitted infections (STIs) and the emotional aspects of your relationship. If you have concerns about pregnancy or STIs, it may be beneficial to consult with a healthcare provider for personalized advice and guidance. They can provide you with more information on safe sexual practices and family planning options that suit your needs.
