Diaphragm with Spermicide

What Is It?

A diaphragm is a dome-shaped latex (rubber) cup which is inserted by the individual into the vagina before intercourse and covers the cervix (the opening to the uterus).

How Does It Work?

Cup acts as barrier to semen contact with the cervix. Spermicide kills sperm. Fertilization does not occur.

How Is It Used?

Clinician fits women with proper size and teaches correct use. Spermicide cream or gel/jelly is placed in the cup before insertion. Before sex, diaphragm is placed in the vagina, covering the cervix. Diaphragm is left in place for at least 6 hours after sex. Additional application of spermicide is needed for each act of intercourse.

How Well Does It Work?

Typical use: 80%. Perfect use: 94%. Failure rate increases with increased sexual activity (more than 3 times a week).

What Are Its Main Advantages?

Reversible. Can be used with or without partner cooperation. Can be placed in vagina up to 6 hours before sex.

What Are Some Possible Problems?

Requires a prescription and clinic visit. May be difficult for some women to insert. Some individuals are allergic to the rubber or the spermicide. Pelvic pressure, vaginal discharge, or vaginal irritation if left in too long. Increased risk for vaginal and urinary tract infections. Increased risk for toxic shock syndrome; must be removed within 24 hours. Cannot be used with oil-based lubricants or vaginal medications.
