What is Caya®?

Caya® is a single size silicone diaphragm with an oval contoured shape, and a flexible rim. The manufacturer recommends using a lactic-acid-containing gel as a lubricant. The gel is applied to the diaphragm, the rim is squeezed and the diaphragm is inserted into the vagina. It sits across the vagina and covers the cervix. One end of the rim sits high up behind the cervix and the other tucks under the pubic bone in front.

How does the diaphragm work?

The diaphragm prevents the sperm from entering the uterus and swimming up to meet the egg and joining together to become a pregnancy.

After intercourse the diaphragm must be left in place for six hours. During this time any sperm in the vagina die due to the normal acid environment in the vagina.

What are the advantages of Caya® as a method of contraception?

  • It is a non-hormonal method
  • It can be inserted well before sexual activity
  • It can be purchased from a pharmacy or a True clinic without a prescription, and you can insert the device yourself
  • It can be used in a regular relationship or for intermittent sexual activity
  • It can be used by men and women who have a latex allergy

What are the disadvantages of Caya® as a method of contraception?

  • The Caya® does not fit all women – it is designed to fit 80% of women
  • It requires consistent and careful use to be effective
  • It does not protect against sexually transmissible infections

Using a Caya®

  • The lactic-acid-containing gel should be applied to the diaphragm within two hours of intercourse. If there is any longer gap, then more gel should be used. The gel is not a spermicide.
  • After inserting the Caya®, check that the cervix is covered by feeling with your fingers.
  • When it is time to remove the diaphragm, insert a finger into the vagina just behind the pubic bone to hook down and remove the diaphragm.
  • Wash the diaphragm after use and dry thoroughly.
  • Do not use any other products on the diaphragm.
  • If well-cared for, the diaphragm can last two years.
