Caya Contoured Diaphragm

Take Control of Your Contraception Naturally

The Caya Contoured Diaphragm is a revolutionary approach to hormone-free birth control, developed by women and female health professionals who believed contraception should work with your body, not against it. As the first new diaphragm design to enter the market in over 50 years, Caya replaces one-size-doesn’t-fit-all thinking with a precisely contoured shape engineered to fit most women comfortably and effectively.

How It Works

Caya is a soft, flexible silicone diaphragm that sits comfortably inside the vagina, covering the cervix to create a physical barrier that prevents sperm from reaching and fertilising an egg. Used alongside a water-based contraceptive gel, it provides a double layer of protection, the diaphragm blocks physically while the gel alters the vaginal environment to be inhospitable to sperm. Simply apply gel, insert before sex, and leave in place for at least 6 hours afterward. That’s it.

Designed for Real Life

Unlike traditional diaphragms that required a clinical fitting for each individual size, Caya’s innovative contoured shape fits most women without a customised fitting. Grip bumps along the rim make insertion more secure and accurate, while a built-in removal dome makes taking it out simple and intuitive. In clinical studies, 85% of users found Caya easy to use, and over 95% reported it was comfortable for both partners.

100% Hormone-Free

For women who can’t or choose not to use hormonal contraception, Caya is a welcome alternative. There are no hormones to disrupt your cycle, no side effects such as weight gain or mood changes, and no impact on your libido. It’s safe to use while breastfeeding, and because it’s only in your body when you need it, your fertility returns immediately when you stop using it.

Cautions:

Caya should always be used with a water-based contraceptive gel for maximum effectiveness. Do not use silicone-based lubricants, as these are not compatible with the diaphragm material. Replace your Caya every two years from first use.
