Caya is 100% hormone-free! It’s without side-effects like weight gain and migraines, and it’s healthier if you’re breast feeding.

Woman controlled

Caya is ready when you are. It’s not always in your body like the pill or an IUD. And unlike condoms, your birth control is yours to manage.


Caya lasts two years. It is an affordable method of birth control. Once you have a prescription, there’s no need for follow-up visits.

How Does Caya Work?

Caya is a soft, flexible, contoured diaphragm that covers your cervix so sperm can’t get in and fertilize an egg.

In studies, 85% of consumers found Caya easy to use. More than 95% found it comfortable for both partners.

Apply a water-based contraceptive gel
to the Caya diaphragm.

Insert Caya before having sex, making sure it covers the cervix.

Leave Caya in place for 6 hours after having sex before removing.

Wash with water and soap before storing, and reuse up to 2 years.


Your Questions Answered

No. Because Caya is hormone free, it will not affect how you feel about having sex. The moment of intimacy shouldn’t be interrupted by use either, as insertion can be done up to two hours ahead of sex, and Caya needs to be left in for 6 hours after sex.
Two years from the first use. After 2 years, the nylon ring inside Caya loses its “bounce back,” which can make it less effective. We recommend you write the date of first-use on the box, or put a note in your calendar to order a new one earlier than 2 years from the first-use date. Any Caya diaphragm older than 2 years, no matter how often it was used, should be discarded.
Yes. The United States FDA requires that patients have a prescription for the diaphragm. Your healthcare provider can dispense Caya to you at your appointment, or provide you with a prescription for you to fulfill. See our Get Caya page for prescription fulfillment options.
