Can You Get Pregnant from Intercourse with Incomplete Erection?

Partial erection without a condom?

Doctor, I would like to ask, yesterday I had unprotected intercourse with my boyfriend when he was not fully erect or engorged, and we only had four or five thrusts.
Is there a chance of getting pregnant? If I find out I am pregnant when I take a pregnancy test, does that mean I cannot take emergency contraception and would only have the option of abortion?

When it comes to the possibility of pregnancy from intercourse with incomplete erection, it's important to understand a few key points about male ejaculation and sperm viability. During sexual intercourse, even if the male partner does not achieve a full erection, there is still a possibility of sperm being present. This can occur due to pre-ejaculatory fluid, also known as pre-cum, which can contain sperm. While the amount of sperm in pre-ejaculatory fluid is generally lower than in ejaculate, it is still a potential risk for pregnancy.

In your case, since the intercourse was brief and the male partner was not fully erect, the likelihood of pregnancy is reduced but not eliminated. The fact that you had only a few thrusts may lower the risk, but it does not completely rule it out. If there was any pre-ejaculatory fluid released, there could still be a chance of sperm reaching the vaginal canal.

If you are concerned about the possibility of pregnancy, it is advisable to take a pregnancy test after the expected date of your next period. Most home pregnancy tests are reliable when taken after a missed period, as they measure the hormone hCG (human chorionic gonadotropin), which is produced during pregnancy.

Regarding the use of emergency contraception (commonly referred to as the "morning-after pill"), it is most effective when taken as soon as possible after unprotected intercourse. If you are already pregnant at the time of taking the test, emergency contraception will not be effective, and the options would then shift to discussing your pregnancy with a healthcare provider. If you find out you are pregnant, it is crucial to consult with a healthcare professional to discuss your options, including the possibility of continuing the pregnancy or considering termination.

It is also important to note that if you are considering taking emergency contraception, it is most effective within 72 hours after unprotected intercourse, and some types can be effective up to 5 days after. However, the sooner you take it, the better the chances of preventing pregnancy.

In summary, while the risk of pregnancy from intercourse with incomplete erection is lower, it is not zero. If you are concerned about the possibility of pregnancy, taking a pregnancy test after your missed period is the best course of action. If you are pregnant, consulting with a healthcare provider will help you understand your options and make informed decisions about your reproductive health.
