If you have a vagina, you’ve probably been told it’s a vagina absolutely must to pee immediately after sex to prevent urinary tract infections (UTIs). But it turns out there isn’t much evidence to support this idea. There is shockingly little research on whether this oft-repeated advice actually works. One study in the so-called magazine Evidence-based practice found that, in general, there appeared to be no difference. But that’s just one study, and the results didn’t point strongly in either direction.

The American College of Obstetricians and Gynecologists (ACOG) does not include urination after sex in the his tips for preventing UTIs. Here’s what they are do recommended:

  • Wash the skin around the anus and genital area.
  • Drink plenty of fluids (including water) to flush bacteria out of the urinary system.
  • Empty your bladder as soon as you feel the need or about every two to three hours.

They point out that factors such as pregnancy, diabetes or going through menopause can increase the risk of contracting a UTI. And it seems that some people are just more prone to them: If you’ve had a UTI before, your chances of getting one again are higher than someone who’s never had one.

That said, if you’ve been peeing after sex, there’s no need to break the habit. Although there is no conclusive evidence that it helps, there is also no conclusive evidence that it harms – or even that it is useless.

Does urinating after sex prevent pregnancy or STIs?

While we’re at it, I’d like to address two myths that have gotten mixed up in the whole pee after sex advice. Peeing after sex is no they can prevent pregnancy or prevent sexually transmitted infections.

When it comes to preventing pregnancy, the sperm goes into the vagina, not the urethra. These two holes are close together, but they’re not the same thing, and the urine that leaves your urethra has no effect on what’s going on in your vagina, cervix, or uterus. People trying to get pregnant may have heard the advice to delay urination for at least a short while after sex so that gravity will help their chances of conception – but American Society for Reproductive Medicine notes that “this belief has no scientific basis.”

Urinating after sex has not been found to have a significant effect on the risk of contracting HIV, chlamydia, herpes, or any other sexually transmitted infection. To prevent STIs, ACOG recommends using condoms, being aware of the increased risk of anal sex or other actions that can break the skin, and making sure to get vaccinated against HPV and hepatitis B, both of which can be sexually transmitted.
