You may have heard that the pull-out method is a way to help prevent pregnancy—and that’s true, it can reduce the risk. But it’s not as reliable as other methods, especially because of something called precum. Let’s talk about what precum is, the risk of pregnancy from precum, and what you can do to protect yourself.

If you’re looking for a birth control method to prevent pregnancy, Hey Jane offers 100+ options (including non-hormonal methods), from the comfort and convenience of your phone. Click here to learn more.

What is precum?

Precum, or pre-ejaculate, is a clear fluid that comes out of the penis when someone is sexually aroused before ejaculation. It’s made by the Cowper's glands and helps lubricate the urethra (the tube where urine and semen come out). It also neutralizes any acidity in the urethra which creates an environment to keep sperm healthy during ejaculation. Most people can’t feel or control when it comes out, and many don’t even notice it.

Does precum contain sperm?

Precum can carry sperm in certain cases, even though precum itself doesn’t come from the testes. Research shows that anywhere from 17% to 37% of people have sperm that’s capable of moving or swimming in their pre-ejaculate fluid.

Can you get pregnant from precum?

Yes. If precum gets into the vagina and contains sperm—especially during your fertile window (the 6 days when you’re most likely to get pregnant)—you can get pregnant, even if ejaculation within the vagina doesn’t happen. The likelihood of pregnancy depends on several factors.

How likely is pregnancy from precum?

Pregnancy Risk Factors
Factors Risk of Pregnancy
Unprotected sex Moderate to high: Because precum can contain sperm, if it enters the vagina during your fertile window, pregnancy is possible—even if ejaculation doesn't occur.
On your period Low: You are less likely to get pregnant during your period, but it’s possible—especially during a short cycle with early ovulation. Sperm can live up to 5 days inside your body.
When using a condom correctly Low: When used perfectly, condoms are 98% effective at reducing pregnancy—a properly used condom catches precum and semen, significantly lowering the chance of pregnancy. Breaks or slips can increase risk.
When using a condom incorrectly Moderate to high: If the condom is put on late, removed early, or used incorrectly, precum may still reach the vagina, which can result in pregnancy.
On hormonal birth control Extremely low: Hormonal birth control has the potential to be up to 99% effective at preventing pregnancy. With typical use, hormonal birth control is around 91% effective, even if sperm is present in precum.
Emergency contraception taken after sex Low to moderate: The sooner emergency contraception is taken after unprotected sex, the better it works. It can reduce the chance of pregnancy but isn’t 100% effective.

How to lower the risk of pregnancy from precum

You can reduce your risk by using protection and understanding your options.

1. Use reliable birth control

Hormonal birth control methods like the pill, patch, ring, IUD, or arm implant are very effective when used correctly. Non-hormonal methods including condoms and diaphragms, especially when used from the start of sexual activity, can also help prevent pregnancy.

2. Don’t rely on the pull-out method

The pull-out method, or removing the penis before ejaculation, is better than nothing, but it’s not nearly as effective as other forms of contraception—mostly because of precum. It’s easy to mistime or mess up, which makes it risky. If the pull-out method is best for you, you might find tracking your cycle is helpful to avoid sex during your fertile window when you’re most likely to get pregnant.

3. Consider emergency contraception

If you’ve had unprotected sex, the condom broke, or you’re unsure if precum might have entered the vagina, emergency contraception like Plan B or Ella can help reduce the chance of pregnancy. Emergency contraception works by delaying ovulation—so there’s no egg for sperm to fertilize. The sooner you take it, the more effective it is.

There’s a lot of misinformation floating around about the precum and the pull-out method. The bottom line is that precum can contain sperm—meaning pregnancy is possible, even without full ejaculation. Understanding how pregnancy occurs, when you're most fertile, and what precautions to take can empower you to make informed choices about your reproductive health. Whether you're using fertility tracking, condoms, hormonal birth control, or considering emergency contraception, there are effective ways to protect yourself. If you need help navigating an unplanned pregnancy, schedule an online consultation with a Hey Jane provider today.
