Can Pre-Ejaculate Fluid on Thighs Lead to Pregnancy Risks?

Regarding the possibility of pregnancy from contact with pre-ejaculate fluid?

Hello, doctor.
I would like to ask about a situation with my boyfriend.
When he hugged me, he had a physiological reaction, and I felt that part of his body touching the inner side of my thigh.
After some contact, I noticed a little liquid on his hand, which may have come through his underwear.
I'm not sure if that liquid flowed onto my thigh because I was lying down and wearing cotton pants and underwear.
I'm worried that if the liquid dripped down, it could lead to pregnancy.
Can you tell me if pre-ejaculate fluid on the inner thigh can cause pregnancy through cotton pants and underwear? I noticed that today is three days before my ovulation period according to my app.
Should I be concerned about the possibility of pregnancy? Thank you, doctor.

More Info

The concern regarding the potential for pregnancy from pre-ejaculate fluid (also known as pre-cum) is a common question, especially among individuals who are trying to understand their reproductive health. Pre-ejaculate fluid is produced by the Cowper's glands and can contain sperm, although typically in much lower concentrations than ejaculate. The primary purpose of this fluid is to lubricate the urethra and neutralize any acidity that may be present from urine.

In your specific situation, the likelihood of becoming pregnant from pre-ejaculate fluid that has come into contact with your thighs through clothing is extremely low. Here’s why:
1. Sperm Viability: Sperm cells are quite sensitive to environmental conditions. Once sperm is exposed to air, it begins to die quickly. The chances of sperm surviving on fabric, such as cotton underwear or pants, are minimal. Even if there were sperm in the pre-ejaculate fluid, the likelihood of it remaining viable after being transferred to your thigh through clothing is very low.

2. Distance and Barriers: For pregnancy to occur, sperm must travel through the vaginal canal to reach the egg. The distance from your thigh to the vaginal opening, combined with the barriers of clothing, makes it highly unlikely that any viable sperm could reach the egg.

3. Timing: You mentioned that you are approaching your ovulation period. While this is the time when you are most fertile, the risk of pregnancy from the scenario you described remains low. If you are concerned about potential pregnancy, it is always advisable to use reliable contraception methods to reduce any risk.

4. Pre-ejaculate Fluid: While pre-ejaculate can contain sperm, the concentration is generally much lower than in ejaculate. Studies have shown that while there is a possibility of sperm being present, the actual risk of pregnancy from pre-ejaculate is significantly less than from ejaculate.

5. Psychological Impact: It’s important to address the psychological aspect of your concern. Worrying about unintended pregnancy can lead to anxiety, which may affect your overall well-being. If you are sexually active and concerned about pregnancy, consider discussing contraceptive options with your healthcare provider to find a method that works for you.

In conclusion, while it is theoretically possible for pregnancy to occur from pre-ejaculate fluid, the specific circumstances you described—contact through clothing and the nature of pre-ejaculate—make it highly unlikely. If you have further concerns or if your situation changes, it would be beneficial to consult with a healthcare professional who can provide personalized advice and support. Additionally, if you are actively trying to avoid pregnancy, consider using more reliable forms of contraception.
