I'm afraid of getting pregnant?


I would like to ask the doctor, if I had intercourse with my girlfriend and I did not ejaculate inside but only thrust a few times, is there a chance she could get pregnant? I'm worried...

As long as there is penetration into the vagina, even without ejaculation, there is still a possibility of a small amount of sperm entering the vagina, which means there is still a slight chance of pregnancy.

When it comes to the question of whether you can get pregnant from pre-ejaculation (often referred to as "pre-cum"), the answer is nuanced and involves understanding the biology of male ejaculation and the potential risks associated with it.

Pre-ejaculation fluid is a clear fluid that is released by the Cowper's glands during sexual arousal. Its primary function is to lubricate the urethra and neutralize any acidity in the urethra from urine, creating a more favorable environment for sperm. While this fluid itself typically does not contain sperm, there is a possibility that it can carry sperm from a previous ejaculation that may still be present in the urethra. This is particularly relevant if the male has recently ejaculated and has not urinated since then, as urination helps to clear any residual sperm.

Research indicates that while the likelihood of pregnancy from pre-ejaculation is lower than from full ejaculation, it is not zero. Studies suggest that pre-ejaculatory fluid can contain viable sperm, and thus, there is a risk of pregnancy if it comes into contact with the vaginal canal. The risk of pregnancy from pre-ejaculation is estimated to be around 4% to 27%, depending on various factors such as timing in the menstrual cycle and the presence of sperm in the pre-ejaculate.

Given your situation, where you engaged in sexual activity without ejaculation inside the vagina, the risk of pregnancy is still present, albeit lower than if ejaculation had occurred inside. If you are concerned about the possibility of pregnancy, it is advisable to consider emergency contraception options if you are within the appropriate time frame (typically within 72 to 120 hours after unprotected intercourse). Additionally, using condoms or other forms of birth control in the future can significantly reduce the risk of unintended pregnancy.

It is also important to note that pre-ejaculation does not provide protection against sexually transmitted infections (STIs). Therefore, if you are sexually active, it is wise to discuss safe sex practices with your partner and consider regular STI testing.

In summary, while the chances of pregnancy from pre-ejaculation are lower than from full ejaculation, there is still a risk involved. If you are worried about the possibility of pregnancy, it is best to consult with a healthcare provider for personalized advice and to discuss contraceptive options that suit your needs.
