Why it's done

When used with spermicide, the diaphragm helps prevent pregnancy. Among various benefits, the diaphragm:

• Allows prompt return to fertility
• Can be used as a backup method of birth control because it's effective immediately after insertion
• Can be used during breast-feeding beginning six weeks after childbirth
• Can be inserted up to six hours before sex and left in place for up to 24 hours
• Doesn't require that your partner use or wear anything for contraception
• Has few if any side effects

The diaphragm isn't appropriate for everyone, however. Your doctor may discourage use of the diaphragm if you:

• Are allergic to silicone, latex or spermicide
• Are at high risk of or have HIV/AIDS
• Are at high risk of pregnancy — you're younger than age 30; you have sex three or more times a week; you've had previous contraceptive failure with vaginal barrier methods; or you're not likely to consistently use the diaphragm
• Have vaginal abnormalities that interfere with the fit, placement or retention of the diaphragm
• Have a vaginal or pelvic infection
• Have frequent urinary tract infections
• Have a history of toxic shock syndrome
• Have significant pelvic organ prolapse, such as uterine prolapse — when the uterus descends into the vagina from its normal position in the pelvis
