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

Yes, it can.
Did you know that a woman's vagina has a natural pH of around 3.8-4.5, while semen has a pH of around 7.2-8? This difference is important for sperm's ability to swim, but it can also upset the pH balance in the vagina after unprotected sex. This can sometimes lead to conditions such as bacterial vaginosis or fungal infections.


Many women who use the A.S tampon after sex have told us how it has not only become part of their hygiene routine, but has also helped to relieve discomfort they often experienced in the past. Amazing, isn't it?

In March 2024, we launched a study to find out how common it is to experience discomfort after unprotected sex and how using A.S can help prevent it. Of the women who answered that they often experienced some form of imbalance after sex, a full 95% experienced a significant improvement thanks to the use of the A.S. tampon.
