Reproductive health deserves more attention, more research, and more answers.

What is Ösel?+

Ösel brings menstrual sample collection, cycle tracking, and reproductive health research into one monthly routine. Get to know your patterns and explore the bigger picture of your reproductive health.

When can I get my kit?+

We’re getting ready for our first release. Kits aren’t available to order yet; availability will be announced here.

Can I use a tampon or a pad?+

Yes. Ösel’s pouches accommodate both tampon and pad samples. Follow the collection guide included with your kit and record the product you used in the app.

Why are there two pouches?+

The pink pouch is for inflammation research. The forest green pouch is for microbiome and pH research. Each has its own label, collection date, and sample ID to keep your samples organized.

Does Ösel replace a visit to my doctor?+

No. Ösel is not a diagnostic service or a replacement for professional care. Your cycle notes can help you organize questions for your healthcare professional. Cycle estimates should not be used as contraception.

Do I have to take part in research?+

Research participation is a separate choice from personal tracking. You decide what you log, and any research participation requires your consent.

Meet yourself, a little more.

Every cycle.
A new beginning.
