The cervical cap (made of silicone) is placed inside the vagina at the entrance of the cervix and prevents sperm from passing through it to reach the egg.

This method is combined with a spermicide that makes the sperm inactive. Spermicide exists in different form: cream, gel, foam, pills, etc.




In Luxembourg, cervical caps are mainly purchased on the Internet, but you can also order them in pharmacies. It is recommended to learn how to place it with a healthcare professional.


After cleaning your hands thoroughly, make sure that the device does not have any holes (you can fill it with water to see if it is perforated or not).


Put spermicide in the hollow part of the device and insert the cervical cap into to vagina, up until reaching the cervix (with the spermicide side facing the cervix).


Place the device at the time of intercourse or up to 2 hours before. Remove the device at least 6 hours after intercourse (the time it takes for the spermicide to makes sperm inactive) and no more than 24 hours after intercourse.


In Luxembourg, only available online.

QUESTIONS Fréquentes

Can the cervical cap be used without spermicide?

Yes, it is possible to use the cap without spermicide, but its effectiveness is reduced. With spermicide, it prevents pregnancy at 68% for people who have never had children and 84% for people who have 2 or more children. Its effectiveness is not tested without spermicide. If you use it without spermicide, try combining it with another technique to increase its effectiveness, such as the internal or external condom, which will also protect you from STIs!

I feel like I have a weird vaginal smell with the cervical cap. Can I perfume it?

It is possible to have a different vaginal smell especially if the cap is left in for more than 24 hours. Only a gentle cleaning with warm water of the cervical cap is recommended. The use of perfumes could disturb your vaginal flora and encourage irritation and infections. Nevertheless, if unusual vaginal smell persists, do not hesitate to consult your physician.

I have inserted my cervical cap upside down! What to do?

Remove it, clean it with warm water and re-insert it. Don’t forget to reapply some spermicide again!

What is the difference between the cervical cap and the diaphragm?

Both devices are placed in the vagina, but the diaphragm is supported by the muscles of the vagina while the cervical cap is placed on the cervix and held in place by suction.

Can I keep the cervical cap on all day?

Yes and no.

Before intercourse: you can keep the cervical cap inserted for 2 hours before intercourse.

After intercourse: you should keep the cervical cap inserted at least for 6 hours after sex. You can keep it in up to 48 hours after sex, but after that you increase your risk of having a toxic shock syndrome.

What is a toxic shock syndrome?

Toxic shock syndrome is a serious reaction that requires a quick trip to the emergency room. It is caused by  a bacteria called “staphylococcus aureus” which is present in 1% of women without causing any problems. However, if there is a lot of fluid in the vagina, it creates a favorable environment for  the bacteria to multiply and, if there is enough of it, it will produce a toxin which will then affect the body. Warning symptoms are fever and flu symptoms, and/or loss of consciousness, after forgetting a tampon, a menstrual cup, a diaphragm or a cervical cap beyond the recommended time. As a reminder, it is advisable to change your tampon every 4-6 hours and to empty your cup every 6-12 hours. The diaphragm can be left in place for up to 24 hours after intercourse, and the cervical cap for up to  48 hours after intercourse. If you have any questions, please refer to the leaflet or to your physician.

How long does it take to change my cervical cap?

The cervical cap can be reused several times, simply wash it with mild soap and water before storing it until the next time it is used. It should be changed when you see that silicone is deteriorating, approximately every 12 to 24 months. 

Can I use lubricant with the cap?

Yes, but only use water-based or silicone-based lubricant. Do not use oil-based lubricants, lotions, creams, etc., as they can alter the latex and thus reduce the effectiveness of the cervical cap and alter the balance of the vaginal flora.
