This Grooming Ritual Might Make You More Prone to STIs

shaving and STIs

While many people like to keep things “down below” more free and natural. However, next time before you take a razor in your hand to trim your business, you might want to think twice – recent research shows that this could make you more prone to sexually transmitted infections.

So, what’s the link between shaving and STIs?

The Study on Shaving and STIs

A study by the University of California and the University of Texas found a strong correlation between shaving and sexually transmitted infections like the human papillomavirus and herpes. The scientists found that people who trim daily or weekly, as well as completely remove all pubic hair more than 11 times a year are 80% more likely to contract an STD.

On the other hand, the people who were grooming less regularly were more likely to get lice. As around 50% of sexually active people will likely contract an STD before the age of 25, this research could help better understand and prevent these infections.

Why Does This Happen?

The scientists offered several explanations of this link between shaving and STIs.

  • Cuts and scratches – shaving can sometimes cause what is known as “epidermal microtears” which can help spread viral STDs.
  • Sharing equipment – although this is a rare occurrence, a shared razor can transmit an STI from one person to another.
  • More activity – people who groom often are usually more sexually active, which leads to a greater risk of STDs.


Although this research doesn’t establish causality (meaning that shaving doesn’t necessarily lead to STDs), it does find a strong link between shaving and STIs.
