How Effective?

Effectiveness depends on the user: Risk of pregnancy is greatest when the cervical cap with spermicide is not used with every act of sex.

Women who have given birth:

• One of the least effective methods, as commonly used.
• As commonly used, about 32 pregnancies per 100 women using the cervical cap with spermicide over the first year. This means that 68 of every 100 women using the cervical cap will not become pregnant.
• When used correctly with every act of sex, about 20 pregnancies per 100 women using the cervical cap over the first year.

More effective among women who have not given birth:

• As commonly used, about 16 pregnancies per 100 women using the cervical cap with spermicide over the first year. This means that 84 of every 100 women using the cervical cap will not become pregnant.
• When used correctly with every act of sex, about 9 pregnancies per 100 women using the cervical cap over the first year.

Return of fertility after use of cervical cap is stopped: No delay

Protection against sexually transmitted infections: None.
