Using the diaphragm or cervical cap

• These devices must be fitted and prescribed by a healthcare professional. You will be instructed on how to insert them.

• These devices must be used with spermicides, which are creams, foams, or gels that kill sperm.

• The diaphragm can be inserted up to 2 hours before sex and the cervical cap up to 6 hours before sex.

• The diaphragm can be left in place for up to 24 hours and the cervical cap for up to 48 hours.

Pros

• Can be inserted ahead of time

Cons

• Requires planning ahead

• May be hard for some women to insert

• May increase the risk of urinary tract infection (UTI) or toxic shock syndrome (TSS), a rare but serious disorder caused by toxins released by certain bacteria

• Must be left in place for 6 to 8 hours after sex

• Cervical cap can’t be used during your period

• Cervical cap is significantly less effective for a woman who has given birth
