- What is a diaphragm?
A diaphragm is a small cup made from silicone. It should be used with spermicide to be most effective.
- How does it work?
It is put inside the vaginal canal, no more than six hours prior to sexual intercourse. Spermicide is added to the diaphragm before insertion in order to ensure it is effective. The diaphragm covers the cervix to block sperm from entering the uterus and the spermicide stops sperm from moving so that sperm can’t get to an egg. Diaphragms are reusable for up to two years and they must be left in for at least six hours after sexual intercourse.
- Does it prevent STDs?
No, a diaphragm does not protect against STDs or STIs.
- Effectiveness
It is 88% effective when used correctly.
- Cost
A diaphragm can cost anywhere from $0 to $75 depending on insurance coverage.
