Pregnancy Risks: Can You Get Pregnant from Water Activities?

Is the risk of pregnancy high?

Hello, doctor.
My girlfriend's last day of menstruation was on February 2nd.
On February 7th, we went to a hot spring.
My girlfriend wore underwear the entire time while I was completely naked.
Before entering the water, I rubbed my genitals against her underwear a couple of times without ejaculation, but there may have been a small amount of pre-ejaculate fluid.
After entering the water, my girlfriend performed oral sex on me, and I ejaculated in the pool water.
A few minutes later, I rubbed against her underwear again a couple of times.
I would like to ask the doctor how likely it is for her to become pregnant in this situation.

Hello, based on your description, the chances of pregnancy are low but not impossible.
As long as there are active sperm 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 peace and health.

More Info

When it comes to understanding the risks of pregnancy related to water activities, it's important to clarify how conception occurs and the factors that influence it. In your scenario, you described a series of intimate actions that took place in a hot spring, including some contact with genitalia and ejaculation in the water.
To address your question directly: the likelihood of pregnancy from the activities you described is generally low, but not impossible. Pregnancy occurs when sperm fertilizes an egg, which typically happens during unprotected vaginal intercourse. In your case, while you mentioned that there was no direct ejaculation into the vagina, the presence of pre-ejaculate fluid (which can contain sperm) and the intimate contact could theoretically lead to pregnancy, albeit the chances are significantly reduced.

Several factors influence the likelihood of conception in such scenarios:
1. Timing of Ovulation: The menstrual cycle plays a crucial role in determining the chances of pregnancy. If your girlfriend's last menstrual period was on February 2, and she has a typical cycle, ovulation would likely occur around 14 days after the start of her last period, which would be around February 16. If you had sexual contact before ovulation, there is a possibility of sperm surviving in the female reproductive tract until ovulation, which could lead to conception.

2. Sperm Viability: Sperm can live for several days in the female reproductive tract, but once exposed to water, especially in a hot spring, their viability decreases significantly. The temperature and chemical composition of the water can affect sperm motility and survival.

3. Pre-ejaculate Fluid: Pre-ejaculate fluid can contain sperm, but the concentration is usually lower than in ejaculate. However, if there was any sperm present in the pre-ejaculate, it could potentially lead to pregnancy if it comes into contact with the vaginal canal.

4. Water Activities: Engaging in water activities like swimming or soaking in a hot spring does not inherently increase the risk of pregnancy. However, the conditions of the water (temperature, cleanliness, etc.) can affect sperm viability.

In summary, while the activities you described do carry a slight risk of pregnancy, the overall likelihood is low, especially considering the circumstances. If your girlfriend is concerned about the possibility of being pregnant, the best course of action would be to wait for her next menstrual cycle and take a pregnancy test if her period is late.
Additionally, if you both are actively trying to avoid pregnancy, it is advisable to use reliable contraception methods. If you are considering starting a family, understanding the timing of ovulation and engaging in unprotected intercourse during that window can increase the chances of conception.
Lastly, if there are any concerns about sexual health or reproductive issues, consulting with a healthcare provider can provide personalized advice and guidance.
