Diaphragm

What’s a diaphragm?

The diaphragm is a reusable latex barrier used by women that prevents sperm from entering the uterus.  This device can be washed and reused.  It acts as a barrier to keep the sperm from entering the uterus and fertilizing the egg.Â

This birth control method is effective 80% of the time if used alone.  To increase its effectiveness against pregnancy to 88%, you must also use a spermicide, applied inside the diaphragm before it is inserted into the vagina.

Be aware that there are many diaphragm sizes!  To ensure the best effectiveness possible, ask a doctor to help you get the size which is best for you.Â

Precautions

  • The diaphragm offers no protection against sexually transmitted infections (STI’s).  A condom is required for protection against infections.
  • You can’t use the diaphragm during your period, because it would prevent the blood from flowing out of your body..

How much does it cost?

You can get a diaphragm over the counter in any drug store or family planning clinic.  Many sizes are available.  To ensure the best effectiveness possible, ask a doctor to help you figure out which size is best for you.  It costs between $50 and $60.

How to use it and practical tips

Using a diaphragm…

  • The first time you install a diaphragm, it wouldn’t be a bad idea to ask a nurse or a doctor to supervise to make sure you put it in correctly.
  • It is recommended to apply spermicide inside the diaphragm before using it.
  • To install it, you must squeeze it and adjust it so that it fits tightly within you vagina – like a tampon. If you’re not sure, follow the instructions provided with the diaphragm.
  • Try to find a comfortable position for installation: crouching, one leg in the air, lying on your side, are all possibilities..
  • If your partner can feel the diaphragm, it means that it’s not correctly positioned or that it’s not the right size.
  • You can apply an extra dose of spermicide just before sex to increase your chances of preventing a pregnancy.
  • Any lubricant must be water based.
  • The diaphragm must stay in place for at least 8 hours after intercourse, but no more than 48 hours.
  • You have to wash the diaphragm after every use with a gentle soap that doesn’t contain phosphate.  Leave it to air dry.
  • You can sprinkle it with corn starch to keep it dry and odor-free.  It must also be kept out of direct sunlight and heat.
  • If the diaphragm is pushed out or removed during sex, you must take the morning-after pill to avoid pregnancy.

What are the Pros and Cons?

The Pros:
  • The diaphragm can be installed up to 48 hours before sex.  This allows for a more spontaneous sexual relationship, and also allows you to install it with more privacy.
  • If you don’t have frequent sexual relationships, it has the advantage of being installed only when needed.
  • It’s usually not felt during sex.
  • The diaphragm produces no hormonal changes.
  • It is available over the counter

The Cons:

  • It is not as effective as other methods if you have frequent sexual relationships.
  • It can cause cramps
  • It can increase the risk of urinary infection
  • The diaphragm doesn’t protect against sexually transmitted infections (STI’s).  A condom is required to avoid STI’s.
  • The diaphragm can be difficult for some women to install and take out.  It all depends on your body shape.  However, like everything else, practise goes a long way.
  • It is recommended to use spermicidal gels or creams with the diaphragm, however, they can lead to irritations or taste bad.
  • It must be well cleaned and properly stored to insure its effectiveness

Complications

Like with tampons, there is a chance of toxic shock syndrome, a generalized blood infection, if the diaphragm is left installed for too long (more than 48 hours).
