The short answer is: No, the sensor itself does not cause infections. As a certified Class IIb medical device, trackle is subject to the strictest quality standards. Here is why you don’t need to worry about the material and what is important concerning its usage.


Certified Safety (Biocompatibility)

The trackle sensor is manufactured under medical conditions and is absolutely germ-free upon delivery. Our biocompatibility testing proves that the material is safe for your body. This testing ensures that:


  • The material does not cause irritation to the vaginal mucosa.
  • No undesirable substances are released into the body.
  • The sensor is suitable for internal use.


What Actually Causes Infections?

A yeast infection occurs when the natural balance of the vaginal flora is disrupted or when germs enter from the outside. While the sensor is not the cause, it can become a carrier. Here’s how:


  • Insufficient Cleaning: If the sensor is not cleaned thoroughly enough after use, bacteria or fungi can multiply on the surface and re-enter the vagina the next time it is inserted. (Learn more here: How do I clean my sensor?)
  • Transmission of Germs: Germs can be transferred into the vagina via your hands during insertion or removal, for example. Therefore, ensure good hand hygiene.
  • External Factors: Often, the infection has nothing to do with trackle at all. Factors such as stress, hormonal fluctuations, taking antibiotics, or excessive intimate hygiene (which disrupts the natural pH value) are common triggers.
