What is this?
The
contraceptive diaphragm is a soft, thin silicone circular dome. It is inserted
into the vagina before sex, covering the cervix to prevent sperm from entering
the womb.
When used
correctly with spermicide, a diaphragm is 92 to 96% effective at preventing
pregnancy. This means that between 4 and 8 out of every 100 people who use a
diaphragm as contraception will become pregnant within a year.
Most women
can use a diaphragm, although it may not be suitable for everyone.
● Have an unusually shaped or positioned cervix, or if you cannot reach
your cervix
● Have vaginal muscles that cannot hold a diaphragm in place, possibly due
to childbirth
● Have a sensitivity or allergy to latex or the chemicals in spermicide
● Have a history of toxic shock syndrome (a rare but life-threatening
bacterial infection)
● Experience frequent urinary tract infections (UTIs)
● Currently have a vaginal infection (wait until it clears before using a
diaphragm)
● Are uncomfortable touching your vagina
● Have a high risk of contracting an STI, such as having multiple sexual
partners or being unsure of your partner's sexual health
How does this work?
A diaphragm
fits inside your vagina and blocks sperm from entering your womb (the cervix).
It must be used with a sperm-killing gel (spermicide).
You only need
to use a diaphragm during sex. After sex, leave it in place for at least 6
hours. It can remain in place for up to 30 hours. Once removed, it can be
washed and reused.
A diaphragm
may be less effective if:
● It’s damaged, such as being torn or having holes
● It’s not the right size for you
● You use it without spermicide
● You don't apply additional spermicide each time you have more sex
● You remove it too soon (less than 6 hours after sex)
If any of
these issues occur or if you have unprotected sex, you may need emergency
contraception.
Diaphragms
come with instructions and are all inserted in a similar manner.

Usage duration recommended:
