Can women's and men's different pH cause an imbalance in the vagina after sex?

Yes, it can.

Did you know that a woman’s vagina has a natural pH level of around 3.8–4.5, while semen has a pH level of about 7.2–8? This difference is crucial for sperm mobility, but it can also disrupt the pH balance in the vagina after unprotected sex. This imbalance can sometimes lead to issues like bacterial vaginosis or yeast infections.

Many women who use the A.S tampon after sex have shared that it has not only become a regular part of their hygiene routine but has also helped alleviate discomfort they previously experienced frequently. Amazing, isn’t it?

In March 2024, we launched a study to find out how common post-sex imbalance is after unprotected intercourse and to see how the use of A.S might help prevent it. Of the women who reported frequently experiencing some form of imbalance after sex, a full 95% noticed a significant improvement thanks to the A.S tampon.
