FREQUENTLY ASEKD QUESTIONS
I am allergic to latex, can I use the diaphragm?
Yes, because diaphragms are in plastic or in silicone.
Won't the diaphragm disappear in my uterus?
The vagina is a set of muscles that ends with the cervix. The cervix has only a very small entrance to the uterus through which sperm, a smear stick or an IUD can eventually pass through. It is not possible for a diaphragm or cervical cap to enter.
Is the diaphragm uncomfortable (for one and/or both partners)?
Very few partners say they are bothered by the diaphragm during penetration.
Can the diaphragm be used without spermicide?
Yes, it is possible to use the diaphragm without spermicide, but the effectiveness is reduced. Without spermicide, the diaphragm is 83-84% effective. With spermicide, it prevents pregnancy by 88%. It is therefore not recommended to use the diaphragm 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 help protect you from STIs!
Can I keep the diaphragm on all day?
Yes and no.
Before intercourse: you can keep the diaphragm inserted for 2 hours before intercourse.
After intercourse: you should keep the diaphragm inserted at least for 6 hours after sex. You can keep it in for up to 24 hours after sex, but after 24 hours you increase your risk of having a toxic shock syndrome.
What is toxic shock syndrome?
Toxic shock is a serious reaction that requires a quick trip to the emergency room. It is caused by a bacterium 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, 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 device instruction or to your physician.
Can you use lubricant with the diaphragm?
Yes, but only use water-based or silicone-based lubricant. Do not use oil-based lubricants, lotions, creams, etc., as they may alter the latex and thus the effectiveness of the diaphragm and/or the vaginal flora.
How long does it take to change my diaphragm?
The diaphragm can be reused several times, just wash it with soap and water before storing it until the next time it is used. The diaphragm should be changed when you see that the silicone is deteriorating, approximately every 12 to 24 months.
