To avoid inflammation or even bleeding found when using other vaginal diaphragms, Marsh uses bio-compatible silicon (BASF) and high precision molding in our products. Please talk to your physician to decide the correct size.

What it is
A diaphragm is a dome made of soft silicone. Along with spermicide, a diaphragm was inserted into your vagina before sex to cover the cervix. They are useful for people who do not want to use a hormonal or long lasting contraceptive.

Why use it
A diaphragm is useful for people who do not want to use a hormonal or long lasting contraceptive. When used correctly they are between 92-96% effective at preventing pregnancy.

Application note:
Diaphragms don’t protect against STIs. Using a diaphragm and a condom together greatly reduces your pregnancy risk while providing protection against STIs.

Spermicides contain substances that kill sperm. Some products also form a thick foam or mucus which blocks the cervix and acts as a barrier against the sperm. They can come in the form of foam, foaming tablets, pessaries, creams, jellies and sponges. Spermicides are not effective enough when used alone, and should be used in combination with barrier methods such as the diaphragm or cap.

Wearing the diaphragm for longer than 24 hours without interruption can promote bacterial growth inside the vagina. These bacteria can lead to Toxic Shock Syndrome. Toxic shock is a rare but serious infection.

This is unlikely. However, some partners may feel the rim of the diaphragm.

The diaphragm is a hormone free vaginal contraceptive that does not disrupt your menstrual cycle.

A diaphragm should be removed no sooner than 6 hours after intercourse and can be left in place for up to 24 hours after intercourse. Additional spermicide is required with subsequent acts of intercourse. If more spermicide is required it should be placed in the vagina and the diaphragm should be left in place.
